I think we pretty much know by now the VALUE of creating Backlinks with Educational sites. By leaving quality comments to posts on these sites we can
a) Create value to the site we are posting the comment
b) Create a quality Backlink to our site to help increase OUR ranking on Google
c) Build a relationship with the Blog owner for the future - for reciprocal comments on our own Blog, plus possible future guest blogging relationships.
But how can we find these EDU blogs, especially ones in our NICHE?
Where you normally type in the URL, type in:
site:.edu inurl:blog +"post a comment" -"comments are closed" -"comments off" +"YOUR KEYWORDS HERE"
Where it says "YOUR KEYWORDS HERE", replace this with the actual keywords that best represent your niche, i.e Internet Marketing, etc
This will bring you up a stream of EDU blogs in your niche for you to create lots of quality backlinks...
Have a great Sunday...
