SEO: Why Do-Follow Blog Comments? 16

Do-follow comment backlinks for SEO

Comment love is about respect for your interlocutor.

I don’t frequently do tactics articles, especially on SEO. This was one occasion I couldn’t pass up.

Many overlook the power of comment love from blogs ( like this one! ) who provide do-follow rel tags on all of our post links and comment links. While comment spam is understood by most blog owners to be bad, many are starting blogs without any conception of why they should provide do-follow rel tags on comments (and posts). As someone who’s been knee-deep into SEO since well BEFORE Google, I’ll enumerate them briefly:

1) Do-follow does NOT mean that spammers automatically get in a comment!
Akismet and Disqus are each more than adequate in catching bot-generated spam (and anything that could possibly be spam). Unknownest to many blog owners, those who regularly post spam comments by hand and have been flagged thus, typically are recognized by most spam filters they were caught on as “potential” spam, and thus must still be marked as “not spam” manually by the blog owner to get through.

2) Do-follow shows your visitors that you value them and where they come from. In SEO, this is called “comment love” and isn’t it grand? Comment love is about respect for your interlocutor as part of the conversation. It’s a time-honored tradition in blogging and be sure that it’s not going away any time soon.

3) They count for link juice and increase rankings in the short term, for your site, and for your visitors sites being linked.
There is a persistently growing myth that Google doesn’t reward comment links that are do-follow, and while there may be times when Google is depreciating their value (as part of their tactics to shake things up for SEO technicians), in general, this is just not the case. In fact, there is way more evidence that Google continues to honor their weight over time than it would non-blog content pages. The only possible reason that Google would diminish their value over time is due to the “freshness” factor of blog posts. But since they are typically THE content type of choice on the internet, and since blogs that seem to be blogs give more info about themselves, there is less potential for running afoul of best practices as it evolves over time.

    Appreciate your cut-to-the-chase clarity and lack of wanking: here and in other posts.

  • Thanks, Malissa! I know for tactics related marketing articles, people want speed and mnemonic ease, so I try.

  • Great tactical info on comment love here Mark. From a basic editorial sense it seems obvious that we want our commenting friends to get value in exchange for their valuable comments. I think articles like this make it easier for people to decide on their own instead of implicitly relying on a generic piece of “wisdom”.

  • I do this for my blog using the “NoFollow Free” plugin for wordpress. It has a number of options to configure the criteria for removing the nofollow attribute from commenter's links.

  • Thanks for the comment and the tip, Bryan.

    I'm glad that Thesis (what this site uses) provides an option for this on the site options menu, but it's worth noting that there are such plugins that help convert WP blogs into comment love blogs, as you say, so thank you for that. All said and done, WordPress provides a lot of freedom from excessive programming via such themes and plugins, including for SEO purposes, in general.

  • Thanks, Justin. I'm all about knowledge rather than blind conformity. There is no reason to deprive the comment love from the visitor. People need to understand that too much has been done already to prevent comment spam from ever gracing their posts via services like Akismet and the hosted WP Disqus plugin.

    Amazing article. Many thanks for posting this! Definitely taking notes!

  • Mark, I always had a problem with this do-follow while I think many folks underestimate the value of a good, targeted AND nofollow link. Even if nofollowed, some links might be just the ones that make the difference.;)
