DoFollow Search Engine - All sites verified January 2009.
The DoFollow Search Engine is based on a list of recently confirmed dofollow blogs. In my experience most of the lists and other search tools are about 50% DoFollow and 50% NoFollow. I found this frustrating and a waste of time. I hope my tool solves that problem.
Comments on DoFollow blogs is especially effective if the blog is also relevant to your niche. Just plug your keywords in and you should have dozens of blogs listed. Please make quality posts. Spam gets delete and makes bloggers change back to NoFollow.
Also please remember that blog comments should be only one part of a larger backlinking strategy.
