Edu Backlinks are backlinks obtained from websites with .edu domains that can be owned by official institutions serving in the field of education and training. EDU backlinks apply to links acquired with the EDU extension on website domains. When a domain name is owned by an educational organization, it will usually have an extension to .edu. These .edu domains are also useful places to connect for you because they can have a lot of authority and often have a good effect on the performance of search engines.
