Can Dofollow Comments Affect Your Blog Reputation and Rank?
Google’s Matt Cutts answers the question: “Are there negative SEO implications to having a blog with do-follow comments? What about commenting on do-follow blogs?”
Short Definition: Dofollow is basically the absence of the “nofollow” tag in a link which is the default setting on blog platforms such as Wordpress and Blogger. Links with a “nofollow” do not count as backlinks to Google and other search engines, so you won’t get the rank benefit. For a more in-depth discussion on this please see my do/nofollow blog post:
Dofollow on blogs has been a source of controversy for years. Although it is a noble thing to reward our readers with “dofollow” there are also drawbacks to consider.
For example the major drawback discussed by Matt Cutts in his video … i.e. comment spam links can damage our blog reputation. But one thing that he doesn’t mention is if your blog is popular it will be targeted by spam websites that list your blog as being “dofollow”, compounding the problem of getting even more comment spam on your blog.
Believe me when I say I spend far too much time weeding the comment spam out every day.
I’m not going to tell you what to do on your blog. It’s your decision. But what is important is that you understand all of the implications for making your blog dofollow, and then decide for yourself.
What about you? Are you a Dofollower?
