Perhaps I missed something but when it comes to relevancy of links (looking at GOOGLE) I found the following:
Only external links (incoming and outgoing) and the number of web pages inside a web site can increase or decrease the amount of PageRank of a web site. Internal links on a web site just "take" the whole amount of PageRank and divide it between the web pages of the web site.
So external links create PageRank, and internal links transport a given amount of PageRank to the web pages of a web site. If this is true you can't compare internal and external links by guessing a "3:1 relevancy ratio".
I found this information here: Google's PageRank and how to make the most of it
If this is true, them I'd like to "crosslink" to another idea
There was a discussion about themes in this forum (Themes here
If an internal link does not create PageRank (or "relevancy" in general), then this could be a good reason why themes do not work inside of a web site (see the tiger and coffee example). And it is not violating the fact that e.g. Teoma is working with themes, because Teoma is concentrating on external links in order to identify communities.
Am I right, have I misunderstood something or is this just fantasy? :halo:
