Everyone these days seem to be interested in more opportunities to gain traction with SEO and link building while the search engines seem to be getting stricter with their policies. If you are a blogger using WordPress to manage your blog content then you should know that commenters leaving comments on your blog posts will get no link juice unless you change the links to dofollow links. WordPress is defaulted at nofollow on the comment links.
A dofollow link is one that passes link juice while a nofollow link doesn’t. What that means is you’ll get credit from the search engines, Google primarily, for your links. That translates into a higher PageRank and better authority and could lead to higher search rankings.
WordPress has a plugin called the Dofollow Plugin. By installing this plugin you are turning your WordPress blog into a dofollow blog instead of a nofollow blog. That will encourage more comments. Many people will not comment on nofollow blogs because they are looking for the link credit. They may be very commenters and therefore you are missing out on their valuable knowledge.
So how does this benefit you? Well, the more comments you get on your blog, the more often the search engine robots will visit it and crawl it, but also more comments means more on-page content, which is good for search rankings. Blog posts with a lot of comments rise in the search engines more quickly and go higher in the rankings.
This is a decision you’ll have to weigh carefully, however. By making your links dofollow you are also inviting more spammers – people who are there just for the link and really have nothing valuable to contribute. Be on notice that you’ll have to spend more time filtering through comments to separate the spam from the valuable comments. If you’re OK with that then the Dofollow Plugin is a good plugin to add to your WordPress blog.
