Hi Guys.
For me, when I searching for .edu websites, I just google [entertainment site:.edu inurl:blog "post a comment" -"you must be logged in"] without "[ ]"
And my keyword is "entertainment" - replace with your own keyword.
That's it!

it is good practice to invest some time in finding and getting links back from .edu websites. This is seen in the eyes of google as an important factor to a websites ranking performance.

I am finding it nearly impossible to find and .Edu links for backlinking any help would be greatly appreciated.
