Many bloggers are more reluctant to comment on other blogs that have the rel=follow than its counterpart rel=nofollow. The reason for dofollow is that each link counts as a “vote” for your site with search engines. These votes increase your page rank and make your site appear closer to the top in search engine result pages.
What was Pagerank Sculpting?
Pagerank Sculpting was the practice of making some links on a page nofollow so the rest of them pass more link juice according to Mr. Google (Matt Cutts).
You’re likely to notice some negative changes in your PR or SERPs if you:
- Do not make your social bookmark buttons nofollow.
- Have paid links and use nofollow for them.
- Use nofollow to link to your competitors.
- Use nofollow on your tags or labels (That’s every blogspot user, btw).
- Have a large nofollow blogroll!
For those keeping score, Matt Cutts (along with Jason Shellen) is the one who started all this no-follow nonsense in the first place. The link is to the official Google blog where he announced the HTML attribute value.
It’s obvious that dofollow blogs will get more attention and comments as well as spam comments, but that can be controlled using comment spam plug-ins or Akismet.
