First thing first. Well, .edu is a domain which can be owned only by the education institute so they are not in a bunch like .com domains. Normally, .edu have better PR and search engine rankings so getting a backlink from those blogs can get you too a high PR and a better search engine rankings.
Due to spammers, some of the sites having .edu domain has decided to make their links nofollow instead of dofollow. So try your luck! Below I am showing you the method of searching Google for .edu sites which allows you to comment on their articles in which you can include an HTML code with a link to your site.
Find the right sites
It is not always enough for you to know about any of the college, university or a school blog which has an .edu domain. So you should know what exactly you want and how to search for it. Below is the first command to have a simple list of .edu sites. Go to Google and perform a search.
Focusing on good blogs
Our aim is to have only those results in search which allows us to comment. Blogs on .edu sites which doesn’t allow us to comment are useless for us so we will have to narrow down the search only to those which blogs allow to post a comment to it. Use the line below and perform a search.
site:.edu inurl:blog “post a comment”
Removing useless blogs
Now after getting a result of blogs which allows you to comment on their post, you will need to remove all those blogs and articles on which the comments have been closed or not allowed after several days. You will also need to remove al those blogs which can allow comments only if you are logged in. So now copy the below line and perform a search.
site:.edu inurl:blog “post a comment” -”comments closed” -”you must be logged in”
Finding the right niche
Now after performing the search from the above point, you will need to find the right niche as per your site or blog you own so that you get a proper backlink traffic. This will get you some targetted traffic as per SEO and also earn you a backlink. Use the line given below and perform the search and you will get the final result.
site:.edu inurl:blog “post a comment” -”comments closed” -”you must be logged in” “seo”
You can replace the word “seo” as per your need.
Leaving a comment
After getting the result and selecting the blog article of your niche, its time to leave a comment there. You will need to act a bit wisely here. You will have to leave a sensible comment as per the article topic. Writing just one line with your blog link might not help you getting your comment approved. So be sensible in leaving a comment.
For .gov blogs, it is all the same, but instead site:.edu , you write site:.gov, everything else is the same.
Well, this is all you have to do to get an .edu backlink for your blog and believe me, it can create wonders for your blog if you succeed in getting couple of backlinks from a blog which has higher pagerank ! Wish you all the best.
