Caspian SEO Blog is now a Do-Follow Blog.
This means any comments you make are dofollow and you’ll benefit by receiving link juice from your comments
However to stop spammers, you must register, you wont get dofollow until you have posted at least 2 valuable comments (e.g. i agree, yes, and other crappy little comments will just get deleted and wont count!)
