Unique root linking domains - clarification

[sssrpm]

Hi guys,

In SEOMoz Search Ranking Factors, one of the the top ranking factors is number of unique root domains linking to the page:

My question is: do these unique root domains need to be unique root domains liking to my domain also?

E.g. www.mydomain.com/landingpage1/ already got a link from www.externaldomain.com

If www.externaldomain.com has another link pointing to www.mydomain.com/landingpage2/ will this link be counted? If yes will the value be diluted as www.externaldomain.com has already linked to www.mydomain.com/

Many thanks.

Hi Casey,

Thanks for your answer.

As you were saying the 2nd link from same domain will be counted, will it be diluted in value even if it's from a different page to the first link?

E.g. Link 1: www.externaldomain.com/page1 linking to www.mydomain.com/page1

Link 2: www.externaldomain.com/page2 linking to www.mydomain.com/page2

Will the 2nd link lose some value as externaldomain.com already linked to mydomain.com?

Thanks.

David

Correct, Each unique linking domain linking to each page will be counted. One thing to keep in mind though, if you are receiving both links from the same page on externaldomain.com the second link to your domain will be diluted some. So if your going after multiple links from a same site, try getting them on different pages where you can have a unique link on separate pages.
