Does CommentLuv Leak Link Juice? – Guest Post by Randy Pickard

Share Button

There has been some buzz lately from bloggers worried that CommentLuv leaks link juice. Researching this question became more than just an academic question for me, as I have been seriously considering about adding CommentLuv to my blog, Internet Marketing Remarks.

What is CommentLuv?

CommentLuv is a plugin that places the title of a recent blog post of a commenter under their comment on a blog article. This can be useful in gaining more comments, as commenters judge they are getting rewarded.  It can also lead to a blog receiving spammy comments.

What is Link Juice?

Link Juice is a term that refers to how much search engine ranking benefit a link passes along.  Based on the original Google algorithm published in 1998, if you had a page with eight PageRank points and four outgoing links, each of the four links would flow two points of PageRank Thus, if it was still 1998 and no changes had been made to the Google algorithm, then having lots of outgoing links to commenters’ posts would probably “leak” link juice. These links to commenters’ posts would have been harmful because they would reduce the link juice passed internally to other pages on your blog. However, the Google algorithm has undergone massive changes in the past 13 years. Position of links on a page is an important factor in how much link juice gets passed, and the comments at the bottom of the page carry much less link juice value than links in the first few paragraphs of an article.

Does CommentLuv Leak Link Juice?

If blogs leak link juice due to CommentLuv, a likely outcome would be that not as much link juice would be passed along via internal links to other pages on the blog. If this were the case, the link authority of the domain would be reduced as a ratio of the link authority of the blog home page. Blogs that do not use CommentLuv can serve as a control group in determining if there is a change in the juice is being passed by internal links and if there is an impact on the domain link authority.

Based on an analysis of home page authority and domain authority utilizing Open Site Explorer, CommentLuv does not seem to be leaking link juice

The chart below shows that the ratio between Home Page Authority and Domain Authority for a selection of 10 blogs that utilize CommentLuv is 87% versus  88% for 10 blogs that do not use it. Given the sample size, 1% is not a statistically significant difference.

www/ 52 43 No 83%
Average 88%

(The control group was selected from blogs featured in 50 Most Influential People in Blogging.)


Importantly, the conclusion that CommentLuv does not leak link juice based on this finding requires two major and potentially flawed assumptions:

  1. The Link Authority results were obtained via SEOmoz’s Open Site Explorer tool. Using Link Authority to determine link juice leakage is only valid if SEOmoz has effectively backward engineered the Google algorithm. An article by Rand Fishkin supports the case that there is a correlation between Link Authority, Google rankings and PageRank. My own testing also seems to support an argument that the correlation is solid.
  2. I have assumed that if CommentLuv enabled sites leaked link juice there would be a drop in domain link authority versus home page link authority. If link juice is leaking away to the sites’ of commenters, then the internal links of the CommentLuv enabled blogs would not be passing along as much link juice and the domain as a whole would suffer a loss of link authority.  The fact that the ratios are essentially the same for both types of blogs seemingly indicates that link authority in not being leaked.

Additional support for a conclusion that CommentLuv does not leak link juice is provided by the strong ranking on search engines for competitive term for sites that feature the CommentLuv plugin.

As a caveat to my conclusion, I did not control for whether or not the blogs used no-followed tags. However, based on Google spam sheriff Matt Cutt’s repudiation of page rank sculpting and no-follow tags as a technique for hoarding link juice, this may not have had much of an effect on the results. For reference, CommentLuv can be set to either no-follow or follow. Since no-follow tags limit the link juice passed along by a comments, they cut down somewhat on the incentive for the insertion of spammy comments.

(Update by Sherryl Perry on 3/16/14): One thing to keep in mind is that by default, the backlinks in user comments (when you use the CommentLuv plugin) are “do-follow”. Potentially, do-follow links to spammy sites can hurt you in Google. To get a better understanding of what do-follow and no-follow links are, check out my post Do You Comment for Backlinks on DoFollow Enabled CommentLuv Blogs?

BTW – One of the benefits of CommentLuv Premium (my affiliate link) is that you can manage your backlinks on the individual comment level. You can also configure CommentLuv so that the do-follow tag is not enabled until a commenter has reached a specific level of approved comments. Some bloggers have set this number as “10” in the belief that spammers will never leave that many comments on your blog.


Based on the results of my study, I’ve added CommentLuv to my blog as I’m reasonably confident that it does not leak link juice.

  1. I was reading about Commentluv being ‘black hat’ SEO. I was searching for more information before disabling the plugin. I am a premium user so I didn’t want to make the decision lightly. Sites that I have visited that use the plugin don’t seem to be penalised by Google but bad SEO is a concern.

    Does anyone have any thoughts on this?

    1. Hi PashaO,
      This is a topic that I’ve blogged about quite a bit lately. Fortunately for you, you’re using the premium version of CommentLuv. That gives you a lot of control over the do-follow tag.

      In light of Google’s recent webspam actions, it’s more important than ever for us to be diligent about monitoring links that we have on our site (to other blogs) and backlinks to our blog.

      Below, I’ve linked to one of my posts that I think you would find helpful. In that article, I outline the steps that I take to monitor my CommentLuv links. I also have linked to other articles that go into more detail about the do-follow tags and what is behind Google’s webspam actions.

      I hope you find the additional reading helpful. Thanks for joining the conversation!

  2. Few days back, I removed commentluv from my blog having fear of loosing page rank. Today I got this post and I understood that I was wrong. I will enable commentluv again. Thank you for bringing this post.

    1. Thanks for letting me know that Randy’s post helped you make that decision. In light of Google’s recent webspam actions (penalizing websites that have what they deem to be “unnatural” links), it’s more important than ever to monitor CommentLuv links for spam. (Not only links in comments left for you but links you’re leaving on CommentLuv enabled blogs.)

    1. Robb,
      One thing to keep in mind is that (by default), the backlinks in CommentLuv user comments are “do-follow”. Potentially, do-follow links to spammy sites can hurt you in Google.

      Thanks so much for your comment. It made me realize that I hadn’t updated this post in a while (which I have done now).

  3. Hi Sherryl.

    CommentLuv does not LEAK linkjuice as you said, but it will PASS ON some linkjuice if you make the link in the comment DO-Follow.

    That said, I saw many of your commenters are concerned about spam. That’s a problem I had a while back on my blog. While CommentLuv and Akismet can deal with MOST spammers, there will always be a few that slip the net. To stop those that slip through, you need 2 more plugins, “Bad Behavior” and “Stop Registration Spam”. By using the combination of CommentLuv, Akismet, Bad Behavior and Stop Registration Spam, I have stopped Spam comments on my sites completely.

    My CommentLuv are setup to allow comments only if the reader are longer that 2 minutes on my site and the comment is longer than 15 words.

    And I ALWAYS moderate comments made on my site, I NEVER auto approve a comment. That way I can leave a reply almost as soon as a comment is posted.

    I hope this help you and your readers.

    God Bless and keep well.
    Abraham van der Linde recently posted..4 Best WordPress Plugins To Prevent Comment And Registration SpamMy Profile

    1. Hi Abraham,

      Thanks so much for the plugin suggestions. I’ll keep them in mind for the future.

      I have my share of plugin conflicts. I think part of the problem is I’m using an older theme and there may also be an issue with the server that my site is hosted on.

      For a while, I was having a huge issue with spam. I was running the G.A.S.P. function of CommentLuv Premium (CLP). When I first installed the Anti-Backlinker plugin (from Andy Bailey), my problems continued until I configured it aggressively (including not allowing comments from anyone who did not have a Gravatar).

      I had my site down to zero spam and things were running fine until I installed the WP Touch Mobile Plugin. Suddenly, people couldn’t comment. Uninstalling the WP Touch Mobile eliminated the error message that people were reporting but instead, they started receiving an error that told them they were a “spambot”.

      After tracing the spambot error to the G.A.S.P. component of CLP, I deactivated G.A.S.P. and Anti-Backliner . I am now running the Anti-Spam plugin (per Ileane Smith’s recommendation). A couple of comments have snuck in but it’s definitely manageable.

      So, for now, I’m sticking with what I’m running. I have CLP set to enable the dofollow tag after 10 approved comments.

      It’s always interesting to hear what plugins people
      Sherryl Perry recently posted..Do You Comment for Backlinks on DoFollow Enabled CommentLuv Blogs?My Profile

      1. It’s always good to go with what you are comfortable with.

        I did not mean to imply that you should use my suggestions, only that is what I use and it works for me.

        But I did see in some of the previous comments that some of your readers are concerned about spam and my suggestions are just one more avenue to follow if they like to.

        PS: I don’t have a mobile plugin, so my blogs are not “responsive”. Maybe it’s time to get one. 🙂
        Abraham van der Linde recently posted..Google Like BlogsMy Profile

        1. Abraham,
          I’m grateful for your plugin suggestions! I encourage people to share their recommendations. I wasn’t looking for a spam plugin when Ileane suggested it but when I ran into problems (again), her suggestion was on my mind.

          I’m not familiar with either “Bad Behavior” or “Stop Registration Spam”. I will definitely check them out the next time I get frustrated with spam or if I run into another plugin issues like not allowing comments. (I run into my share of plugin conflicts and I could be installing your recommendations as early as next week.)

          I’m back to not using a responsive mobile plugin due to the issues that I ran into on my site. It’s frustrating though. I know another blogger who is using the same version of Thesis that I am and that mobile plugin works fine for her. Plus, she’s using CommentLuv Premium too. Go figure! There’s subtle difference with my site that’s causing conflicts.

          Thanks so much for sharing your thoughts with us! Have a nice weekend.

  4. This is a great article. So much emphasis is put on stopping LinkJuice leak from your site and people guard their domain authority by sometimes putting no follow on every external link, which isn\’t good for the web as whole. Healthy moderated comments and guest blog articles are still a source of active content and should be considered so.

    1. Hi Mark,
      First, I’d like to apologize for not replying to your comment for almost a month. (Somehow, it got by me.) You’re absolutely right about “healthy moderated comments” with dofollow links as well as allowing guest blog posts.

      It can be a real challenge to stay on top of dofollow links left in CommentLuv comments especially for those of us who have years of comments. Sometimes, domains change hands and a link that previously pointed to a valuable blog may now point to a spammy site.

      I’ve linked below to an article wrote on what happened to my organic search traffic after Google updated their algorithms. I lost about a third of my traffic. To a large part, it was due to CommentLuv backlinks that had gone awry. One particular problem that I encountered was abandoned domain names that are now parked with GoDaddy. These parked pages are now riddled with AdSense ads. Because they’re live sites, these links don’t show up as broken. The only way to identify them is by visiting the links. (I have over 11k comments. So, that was a big task.)

      Thanks for dropping by and taking the time to leave a comment.

  5. Hi Chetan,
    Thanks for taking the time to let us know that you enjoyed Randy’s article, I’m a big fan of CommentLuv even though it does create more work for me as far as monitoring spam goes. I think it’s worth the extra work to be part of a community of bloggers who support each other with do-follow links.

  6. I was a bit confused after reading the headline of this post. After reading the whole post, it was pretty clear to me. Commentluv is a great plugin to get interacted with the readers of a blog and also it build up authority ranks.

    1. Hi Harvey,
      When CommentLuv first gained popularity, some bloggers expressed concerns about CL leaking link juice. Those concerns seem to have subsided somewhat. Now, there’s a concern that Google may punish us for linking to sites that are spammy or are deemed “low-content”. (CL defaults to do-follow and you either need to manually deselect it or, if you’re using the premium version of CL, remove the link and/or the do-follow tag for individual comments.)

      It’s always been crucial to monitor the sites that we link to. Since Google Panda 2.0, it’s more important than ever to monitor links in your comments.

  7. Very helpful article. I am brand new to the world of blogging, so have been quite confused about which plugin to use for commenting. Right now I use the built in Word Press one, but have never got any comments from it. I’ve also briefly used Disqus, but didn’t like how it looked on my site, and still didn’t get any comments. Maybe Commentluv might be the right choice to help start bringing readers to a new blog. I was concerned about how allowing people to link to their posts would affect my SEO. Now I wonder, does leaving my link when commenting affect my site at all in a negative way?

    1. Hi Ronda,
      Thanks for letting me know that you found Randy’s post helpful. CommentLuv should help you get comments but it needs to be part of your overall marketing strategy. (I’ve linked below to a post I wrote when I first started blogging about developing a commenting strategy.) If I were you, I would install the free version of CL. Be prepared for spam comments. That’s the biggest drawback of this plugin. There is the potential for a negative impact on SEO if you allow do-follow links to unsavory and low quality sites. Just be diligent about monitoring your spam and delete them.

      What you can also do is start building relationships with other bloggers. Follow popular bloggers who are already reaching your target readers. Comment on their blogs. Share their posts on social sites like Twitter and Facebook. Eventually, some of them will start commenting and sharing for you too. Just stay that course for a while.

      One tip – go to and set up your globally recognized avatar. Some bloggers will not accept comments if you don’t have a profile pic associated with your email address. Besides, getting to recognize you is part of your branding.

      Another thing that you may want to do is check out the “Bloggers Helping Bloggers” group on LinkedIn. You can get a lot of support there. Plus, there’s a weekly discussion there for people who are interested in supporting each other by commenting on their blogs. Good luck! Thanks for taking the time to comment.

  8. Good evening, Randy,

    Very informative–I’m just trying to redo my website and was wondering about this plugin. I certainly think it’s useful on the user end–it’s comforting to hear the usage of it will not harm my own site’s rankings, according to how I read your findings. Thank you.


    1. Jec,
      CommentLuv is a great tool for building your blogging community. Your website visitors appreciate being able to leave a do-follow link to your blog while you get the benefit of more visitors. The only downside is that along with more comments, you’ll get more spam. I believe that it’s well worth it though.

      The premium version of CommentLuv has a premium version of G.A.S.P. (Grow Map Anti-spam Plugin) built in but there’s a free version of both to get you started. Good luck with your site and thanks for letting us know that you enjoyed Randy’s article.

  9. I’m just wondering do people put too much emphasis on getting the dofollow links, like how bad for google would it be if everyone decided to put the no-follow plugin on their pages. I’m dofollows probably carry more weight but i think people should have similar amounts.

    1. Julie do-follow links can help (or hurt) your rankings in the search engines. I don’t believe they carry a lot of weigh individually but they’re a piece of the puzzle. It helps to have backlinks from high ranked pages/websites (especially if they’re related to your niche) and they’re do-follow. It also can hurt your SEO if you have do-follow backlinks from spammy sites.

    1. Hi Wilson,
      I’m very happy with CommentLuv Premium. I used the original version initially and while it helped drive traffic to my site, I did not like that all of the links were do-follow. With the premium version, you can strip both the do-follow tag or the entire link from comments individually. That’s a huge advantage because the biggest downside that I see to CommentLuv is that it does attract spammers who are only looking for the link. The GASP plugin (which is included in the premium version) does a great job of catching spam but some comments seem acceptable while you still won’t want a follow link to their site. If you do install it on your site, look for directories of do-follow blogs and get yourself listed. I get referral traffic that way too.
      Sherryl Perry recently posted..Tips for Bloggers | Before You Press that Publish ButtonMy Profile

      1. sound really nice, but what kind of do follow blog directories are you referring to? Is it just like the normal directory submission?

  10. Personally, I feel that it is the quality of content and comment that matters at the end of the day . As media is ever revolving, one can be ensured that his comment will attract attention if it is of high quality that is useful to the public audience.

  11. Blog commenting is the best in terms of seo benefit, when you look at the recent google algorithm it will simply tell you that forum posting is dead. I can not argue much but the point still remain valid due to the fact behind seo and i hope to say google still remain the gaint when it comes to web search. Sometimes when i do comment on blogs i see higher rankings in value compare to getting shitting links from the web, sure blog commenting is effective.

  12. Good information. I am considering trying out commentluv on my blog. Was wondering if the free / lite version allows me to keep the WP default of no follow links or am I forced have do follow links unless I upgrade to premium? Could not find the answer on the commentluv website.
    Lashan W recently posted..Best Free Small Business Software ToolsMy Profile

    1. Lasha,
      People who leave comments on CommentLuv blogs expect their links to be do-follow. That’s the biggest incentives of commenting on these sites.The entire CommentLuv community is built upon this. There’s even a directory of do-follow blogs at (I get a good share of traffic from that site.)

      Of course, CommentLuv does attract spammers and it increases the amount of time you spend monitoring your comments but most of who use this plugin believe the benefits outweigh the cons. Some of the advantages of the premium version is that it is very easy to remove the do-follow tags for individual comments and you also have the option of removing the link. Additionally, you can control things like the number of comments that a person has to leave before their links are do-follow. That’s helpful because some people will start out leaving innocent links and then start linking to spammy sites.
      Sherryl Perry recently posted..Do You Use Google Webmaster Tools Bing or Both?My Profile

      1. Thanks for taking the time to answer my question Sherryl, I did install the lite version and looks good so far. I generally agree with your point of view and have no problem with with a do-follow for valid comments. It’s the spam that I am concerned about and unfortunately so far I’ve been getting a lot of them. Ability to specify which comments gets do-follow would be great, but you are right, it does mean more time monitoring comments.
        Lashan W recently posted..Best Free Small Business Software ToolsMy Profile

        1. Hi Lashan,
          Are you using G.A.S.P. (the Growmap Anti-Spam plugin)? It captures a lot more spam than Akismet does. That plugin is built into the premium version of CommentLuv but it’s also available as a free stand-alone plugin. If you’re not already using that, it should help.

  13. I personally use seomoz’s toolbar to determine if a page will give a lot of link juice. It gives a page authority number. Obviously, the higher the number, the more link juice a page will provide. You also have to take into account the number of links already on a page. The more links on a page, the more the page’s link juice will be diversified.

    1. Maybe Basit is one of the spammers everyone is talking about 🙂

      Fwiw in the current environment I entirely agree with your strategy but ofcourse whether rewarding your readers is worth the price to build up a community is dependent on Google’s algorythm. There is always a turning point where it’s no longer worth it but I would think that it is highly unlikely for Google to adjust the algo in such a way.

      1. Hi Bram,
        I think the importance of building a community varies based on our individual goals. Building community is extremely important to individuals who depend upon clients. Someone else who is marketing products to the masses still needs to establish themselves as trustworthy but for them spending the time to cultivate meaningful individual relationships may not be as beneficial to them as it would be to me.

        Now that I’m reflecting on this, the vast majority (if not all) of the CommentLuv blogs that pop into my mind all deal with clients rather than products. Sure, lots of them are doing affiliate marketing but they’re also all marketing the same or similar products. So, it does often come down to who doe you want to buy from (which goes round circle to relationship building).

  14. This is a very thorough analysis on the topic. Even many bloggers who have already used commentluv might still wonder if this ever happens.

    With your analysis, people have more confidence in choosing this as a plugin for their blogs.


    1. Thanks for letting us know that you appreciate Randy’s guest post on CommentLuv. A lot has changed since Randy originally conducted his study. So, I honestly can’t vouch for his results. Having said that, even if it was proven to me that CommentLuv linked juice, I would continue using it. Comments are very important to me because it plays a role in my commenting strategy.

  15. What if I don’t have premium version enabled? Btw I just found the you can set minimum number of characters per comment(not sure good or bad). Good because the quality of comments can be increased, bad because it can annoy your active commentors.

    1. I’m not sure I understand your question Rahul. Do you own a license to the premium version?

      You have to be cautious with tweaking the settings too much because you do risk annoying active commentors. When I fist set the minimum amount of time that someone needs to be on my site, a regular blogger emailed me that there was something wrong.

    1. Kevin,
      Are you using the free version of CommentLuv? If you are, what do you use for your anti-spam software? If you’re still using Akismet, you may want to switch to G.A.S.P. (the Growmap Anti Spam plugin). That seems to work better and it is actually built into the premium version of CommentLuv.

    1. Thanks Bharat. I wrote a few more posts about CommentLuv when the premium version first came out. The premium version does have a lot more controls built in to help cut down on spam. For instance, you can set the amount of time that someone has to be on the page before leaving a comment. You can also set the number of comments someone has to leave before they can leave a link and you can also set the number of comments they need to leave before it gets the do-follow tag.

  18. thanks for the information. I have a brand new internet marketing business and website and am receiving tons of spam comments on my blog posts. I installed a plugin and now the comments have dropped to zero. Im going to try some of the suggestions above.
    I will be back for more reading. The information here was better than some of the forums Im involved in. Thanks again.

    1. Wow! I’m impressed that your plugin is catching all of your spam. Are you using CommentLuv? My guess is no unless you recently installed it and the word hasn’t got out yet. CommenLuv is great and I recommend using it but there’s no doubt that it will increase the amount of spam that you’ll get.

  19. As it is link stays after the post which Google devalues in most of the cases so it won’t hurt…Though it will help commentator to get some traffic…

    1. Tyron,
      If the link is to a spammy site, I believe it can hurt us don’t you agree?The biggest negative that I see to CommentLuv is that spammers do target your blog in search of the “do-follow” tag. CommentLuv Premium arms us with the tools to fight this but it can be very time consuming monitoring links that are left in the comments. Some spammers start out leaving innocent looking links and then after they’ve been accepted and earned the right to have the do-follow tag, they abuse the privilege.

  20. Randy, good to know. I am investigating this plugin since I can see that pages that use it are doing very well in Alexa. It seems the Google algorithm now is getting more and more into social media.

    1. Hi George,
      There are a lot of advantages to using CommentLuv and you can always start out with the free version. It certainly helped drive a lot of traffic to my blog. People seem to love the incentive of being able to leave a do-follow link to one of their posts. It does tend to attract more than it’s share of spam though. So be sure that you’re using G.A.S.P (the Growmap anti-spam plugin) instead of Aksimet. That helps a lot. The premium version of CommentLuv has G.A.S.P. built into it. It also has some powerful options to control spam by being able to tweak your options with parameters such as the amount of time that someone has to be on your site before commenting. You can also easily remove the do-follow tag from an individual comment as well as keep the comment and remove the CommentLuv link completely.

  21. Comment luv is a fantastic plugin and while i do agree that it can attract more spammers it also helps to increase the activity of a blog.

  22. I don’t think comment luv leaks link juice but it definitely brings more spammers than other commenting system.

    1. Rahul,
      I agree with you that CommentLuv sites do attract more spammers. That’s why, I’m grateful that Andy Bailey added more spam controls to the premium version. You can now tweak CommentLuv Premium to require a specific number of words and the length of time that someone has spent on your site before their comment is sent to moderation. Otherwise, the comment goes to spam.

  23. Thanks for sharing new ideas. By the way if a link doesn’t pass link value then what’s the use of posting links then? It is clear that we are not doing social work here, we post our opinions and suggestions to a post only to get a back links and if we realize that we will not get any benefit of the same, we will stop doing that.

    I personally believe that every link passes link juice/link value if it is not a ‘nofollow’ one.


    1. Hi Aaron,
      I think that it does pass some link juice. Personally, I don’t comment on CommentLuv sites looking for the SEO value of the link. Rather, I value the opportunity to expose my blog to new readers. Whenever possible, I link to an article that relates to the topic that I’m commenting on in hopes that someone will follow the link to my blog and then like what they see.

  24. I am also convinced now that commentluv doesn’t leak link juice. But if so, why are commentluv blogs recommended by SEO experts? If the link juice doesn’t pass, how can it be beneficial from an SEO point of view?

  25. This is good to know. Although commentluv does not link juice, as per your study, keywordluv does. I was on the top of page two for “earn more money.” on Yahoo and Bing. I thought a bit more link juice would push it to page one. Wrong!!! I am now nowhere for those keywords. I got pushed back a page on Google, also.

    1. Hi David,
      That’s very interesting that you’ve found that keywordluv leaks link juice. Just so that I understand, are you saying that your comments (that you left on other blogs that have keywordluv enabled) is hurting you? (I just want to clarify that having keywordluv enabled on your site isn’t what’s negatively affecting your ranking for those keywords.)

      1. There could have been so many factors influencing you losing ranks on those keywords. Even by trying to get more backlinks through comments you could have schewed your linkprofile in an unnatural way which may have caused a drop. I would be interested to know how you are so sure that’s the tool that caused you to lose rank..

    1. Thanks for letting me know that you found this article helpful Bethany. A great way to get started with CommentLuv is to download the free version. If you find it’s helping you to increase your website traffic, you can always upgrade to the premium version. I find the premium version to be very valuable because of the additional controls that it offers. When you start getting a lot of comments, you may want to upgrade. If you’re not already using G.A.S.P. as your anti-spam plugin, you may want to look into installing that too. G.A.S.P. is much better than Akismet. It’s actually built into the premium version of CommentLuv.

  26. This article is wonderful and helping people to understand what they are trying to understand!I salute to the article of Randy!This is so very incredible…

  27. Thanks for clearing this up and taking the time to research, it was a question I asked G as I wasnt happy with the existing comment plugin on my site. Giving it a go now!

  28. Hi Randy

    I’ve been studying this as I wasn’t completely happy with my existing comments plugin and I like the comment luv features. So thanks for all your research and hard work to determine if it is link leaking …

  29. To deal with link juice being leaked to non-essential pages simply add a nofollow tag to these links. This is particularly important where you have a common header or footer for all your pages, which also include navigation.

  30. Seems that Google stopped using comment links as authority links some time ago so it makes sense that the links in comments would not link juice.

      1. Hi Sherryl,

        This is were the security questions come into play, people who are using spamming tools to find holes in blogs security systems cant leave comments on your site if you have a security question such as yourself.
        As you mentioned, google is punishing sites who are associated (linked with) sites with poor content or are generally spam related.

        1. I wasn’t aware that google had begun punishing sites based on the content of those who are linking to you! Just more work for us bloggers I suppose!

          Great point Michael, thanks!


  31. Yea, I know what you mean. I’ve gotten flagged by the auto anti spam measures on some blogs and I’m like “Really???”. lol. It’s a bit funny when it happens and I see all these obvious spam posts on the blog freely posting. Ah well, such is life I guess. A lot of the spam is due to SEO companies using auto generated programs to generate garbage blog posts all over the interwebs on whatever random blog/forum they can find. It’s unfortunate that their customers do not realize that they are tainting their websites with spammy backlinks.

    Anyway, it was nice to meet you. It’s always refreshing to see someone who replies to their blog posts. Thank you for the conversation.

    1. Thank you for the conversation too Don. I appreciate the input about SEO companies generating spam. It reinforces some of the advice that I’ve read about using caution when you hire a company to outsource SEO or any other service for that matter. I was just having a discussion with a group of bloggers and we were commenting on how easy it is these days for anyone to hang out a virtual “shingle” and purport to be an expert. It’s dangerous.

      1. Yes, it is. You have to be very careful who you have do your SEO. Most SEO companies out there are worse than used car salesman. If you’re lucky they won’t rip you blind. It’s difficult to find one that is not only honest and does white hat SEO, but also actually knows what they are doing. Many of them get by with knowing little because so few people knew much about SEO. I’ve seen so many people taking advantage of for thousands of dollars as a result of a scammy scummy SEO Firm. Always ask them if they do it by hand, or if they used automated programs.

  32. Of course it ‘leaks’ link Juice. Comment Luv is meant to make the links followed, which leaks some link juice to the linking sites.

      1. It is only a fraction. Yes, I agree. Linking to spam sites and black hat sites is very bad. Keyword Luv, and comment Luv are great tools and allow rewards for bloggers. It can attract the spammers, but I personally think it’s not a good idea to punish all bloggers because of spam. One problem I have on my blog is having to go through thousands of spam bot messages to pick out the ones that are legit. A pain in the neck lol

        1. Spam is such a pain. I just went through my spam folder today and recovered two legitimate comments. Both people had profile pics and used their real names. They went into spam, yet, I had about ten comments today that went into moderation and the majority of them had keywords for their names and the content was questionable at best.

  33. Good morning again, Randy

    I’m so glad your site is DOFOLLOW. Nofollow sites (default in wordpress) are simply IGNORED by Google. (Although not by other search engines) So nofollow sites do not show link leakage, they show NO linkage at all in the eyes of megalomaniac G.

    Warm regards
    Al Joh 🙂

  34. Top of the morning to you, Randy

    Link juice is leaked mainly through low or no PR on the page your comment is on. Note this is NOT, NOT the PR of the home page.

    All the best of British luck to you.

    Fond of the presentation of your site, in passing. In the infamous words of our muscle proud Arnold S, “I’ll be back” (if you’ll have me)

    Warm regards
    Al 🙂

  35. Hi Sherry
    I believe this kind of blogs posts and discussion encourage people to use commentluv plugin on their blogs.This is a great job and hope people will know the real value of comentluv and keywordluv plugin for their blogs.
    Many Thanks

  36. Excellent insights on Comment luv sites and links, you have done your research. Thanks for writing a neat article.

  37. Link juice is passed anytime an external link is posted on a site, so the answer to the question is a clear yes.

    1. Don, The question I pose would be “Is it worth it to you?”. My answer is yes. I have successfully used CommentLuv to increase quality traffic to my site. Does it take some policing on my part? Yes. Has it become easier with CommentLuv Premium? Definitely yes.

      Thanks for adding to the conversation. This discussion will never get old.

  38. I just discovered keywordluv and commentluv. It is obvious that these plugins pass value to the site of the person placing the comments. I have been searching for several hours for the answer I believe I have found in your post, that being, having the plugin on my site can be a benefit to my site without having to worry about the plugins harming my site in the eyes of Google.

    Thanks for the post

    1. Hi James,
      I strongly believe that you do need to monitor your comments fairly closely if you decide to use this plugin. I have decided that I personally only want links left that I find valuable. I recently went in and removed any links that I had previously approved to coupon sites and review sites that are basically in existence for the purpose of running ads.

      I now have CommentLuv Premium installed. One of the things that I value the most with this upgrade is the ability to leave links and remove individual do-follow tags. I do this I don’t want to completely strip the link from the comment but at the same time I don’t want search engines to follow it.

      1. Thanks for the response. Now, I just have to figure out how to install it on my site. (I am not that technically oriented.)

        1. James, I always backup my database before I install any plugins. Are you installing the free version or the premium? The premium has a lot of settings to deal with. They’re optional but they’re there. If you need help, send me a message using the contact form here. It’s snowing here. SO, I’ll be online working a good part of the day.
