Last week, Matt Cutts got the blogging community in an uproar over whether or not guest blogging was dead. (It’s not.) Actually, what Matt said was that guest blogging for “backlinks” was no longer going to be tolerated by Google and that we should be especially concerned with spammy links in guest posts intended for SEO. He cautioned us to only accept guest posts from trusted bloggers who we could vouch for. That got me thinking about the backlinks that are left in the comments of blogs that use the CommentLuv WordPress plugin.
