More on .Edu Links and Their Value

In our last post, we talked about the value of .edu links for SEO.  After considering comments by Google’s Matt Cutts and the nature of most .edu links, we concluded that there is some substantial SEO power in obtaining inbound links from .edu domains.

Some new information seems to support that conclusion.  A blog post at Divine Write provides notes from the recent SMX Sydney convention.  One of the speakers, noted SEO voice Rand Fishkin, discussed .edu links.  The blogger, Glenn Murray, summarizes:

Trustworthiness of a website – Good ‘degree of separation’ diagram: To Google, a site that’s one link away from a trusted seed (such as Amazon or an edu) is 0.4% likely to be spam, two links away is 1%, three links is 14%. This is why links from seed sites are so important.

Rand’s breakdown of SEO signals:

• Trust/authority of domain = 35%
• On page & keyword = 30%
• Page level link metrics = 25%
• Usage data = 10%

Now, think about what that means in terms of the potential SEO value of .edu’s.  Why does Google use links to determine SERPs?  In essence, it’s because they interpret inbound links as votes of confidence regarding a sites quality and relevance to users.  How does Google dtermine what kind of weight to give those inbound links?  Obviously, the trustworthiness of the source must be a significant consideration.

What do these SMX Sydney notes tell us?  They tell us that Google has a darn good reason to trust inbound links from .edu’s.  

Are .edu links the Holy Grail of SEO?  Of course not.  They are, however, a powerful component to increasing your performance in the SERPs.  Inbound links from .edu’s are just the kind of link Google should be trusting.  Isn’t that the kind of link you want?
