I am getting a lot of "unknown" when it comes to do follow and no follow links. Is it worth commenting on the unknowns?
I would say no. I use SEO QUAKE a long side Fast Blog Finder. When I see an unknown I will go to the page.. scroll to the comments and SEO Quake will tell me if its do follow or no follow.
i do want to know the software power, but i do affraid a bit if the software contains any malware, spyware, or any warez on it.. Could anyone please clarify those? Thanks
