Ignore No Follow
Interesting tips I found at searchenginejournal.com. Loren Baker, editor of searchenginejournal write about Six Explosive Organic & Paid Link Building Tips. And I like tips No. 3. Ignore NoFollow
As a general rule of thumb I tell my employees who are doing quality and relevant comment driven linking to comment on all relevant blogs which allow comments and a URL field. Then, I go back and analyze the percentage of blogs which use NoFollow to those which do not. Usually 65% to 70% of the blogs end up using NoFollow, but search engines follow links and identify sites via links using NoFollow anyway, so this is fine.
This practice results in more natural blog linking and in my opinion, if you only comment in 100% DOFollow blogs or 70% DOFollow blogs, your blog comment participation is not following natural trends, and could be viewed as anchor text and linking manipulation.
I think this make sense, at least for me in this situation :D. I joined SEO contest ( Busby SEO Challenge Contest ), and I try to find dofollow blog with related content. It’s a hard job to do in a short time.
Then, I try to build links via blog commenting, via a nofollow blog, as long as that blog have relevant content with my blog. Is this SEO trick still useful ? Yes, blog commenting is still useful. But, don’t try to make spammy comment, try to adding value to the discussion. And, to see how comment spam can be identified algorithmically read here
