A few people on this forum claim that Google doesn't like sitewide links. Do most of you agree with this claim? Does anyone know if this only targets links that are on every single page of a website? Or would it also apply if the link was just on the majority of the pages...say more than 75%? Thank you.
I think it is more of a question as to whether Google likes site wide links. I think they are either ignored or help in Google.
My experience suggests that as the links from one site to another grow Google discounts them. So having 1 to 5 good related links probably carry some serious weight. Once you start getting a lot of links then they diminish in value pretty fast.
Lots of links from authoritative sites will still count high in google algorithm. If the links are form low quality sites, their value fo rthe SE ranking is also low. Inter-linking inside the same domain is not a problem unless there is duplicate contents (same contents on two different URIs).
