Perhaps you have seen .edu backlinks being sold. In this thread, I would like to give some tips to find .Edu sites. While all the websites obtained might not make it possible to post a link or a comment, I still believe that this method is to be used with moderation. 1 - Go to google 2 - Type in the search box: "your keyword" inurl:blog site:.edu Alternatively, you could type: site:.edu inurl:blog "your keyword" "comment" The results might not be many if your keyword is nichy. In general, I find it better to go for broad keywords. One of the querry mentionned earlier [site:.edu inurl:blog "fitness training" "comment"] led me to find 77 results according to google.
