There is software that will search blogs for you and tell you if they are dofollow. But on another note I would not worry if they are follow or not. Even a nofollow can get traffic.
Well as per my knowledge blog commenting is beneficial in one or other way. Though the other techniques are useful in same manner. My friend if you are searching for blog I suggest you to google it. I'm sure you will find a great and help full list over there.
Hi, Here is the list of blog commenting list. http://www.seopoints.info/2010/06/blog-commenting-list-seo-points/ Thanks
You can do a search on google with the keyword "blog DoFollow lists" or "blogs DoFollow lists high PageRank." . But there are a lot of keywords you can search there. In addition to google, in the digital point forums also a lot of members who give the DoFollow blog list and directory site who's quick to approve. Hopefully it can helped you. .
In google type "dofollow inurl:blog site:.edu" you will get tons of dofollow blogs with .edu extensions, if you are not interested in .edu then change it to .com.
you can use Google dofollow blog search engine to find it Or googling with the keyword phrase "dofollow blog list"
Allow me to put this to song ( to the tune of London Bridge is Falling Down) "There is NO Relevance Do Follow" "Do Follow" "Do Follow" "There is NO Relevance Do Follow" "My fair Lady"
