Well, it appears Google has done another page rank update. So, how did your dofollow blog Page Rank do? Does having a dofollow blog affect your page rank? Honestly, I don’t know. My page ranks have not changed at all – up or down, so I don’t know how they would have been ranked if they were not dofollow.
What are “Do Follow” blogs? “Do follow” is the opposite of “No-Follow”. Wordpress blogs, by default, use the HTML nofollow attribute on links that point away from the blog. This no follow attribute comes into play with the posting of blog comments. The no-follow tag tells the search engines NOT to follow the link to any other web sites.
