Googler, JohnMu, wrote in a Google Groups thread that links from EDU domains are not in itself better links than .com or .net links. John said:
In general, I would like to add that no, backlinks from .EDU domains generally do not get "additional credibility from Google"
I believe this may be one of the first times we have official confirmation in writing from a Google representative that EDU links are not anymore valuable then other types of links.
Here are some of our past articles on EDU links:
- What Would You Do For An .edu Link?
- Finding Some of Your EDU Links with Yahoo Search
- How Do You Obtain Links from .edu Sites?
- Need Help Getting Links from Education (.EDU) Sites?
- Are Links From .edu and .gov Domains Really "Better?"
