For Google, Yahoo and Microsoft search does anchor power trickle up from other pages?
I was explaining anchor power of external links to someone recently and they asked an interesting question. If sub-pages (or subdomains) are receiving inbound links descriptive of the site as well as the homepage, does any of the anchor power (NOT link power, link juice or pagerank) trickle up to the root page. I indicated that if I were an engineer it should but I wasn't sure if it does.
For example, if 40 pages on ford.com all have inbound links containing the anchor SUV and the root page has only three, it would make sense to me that Google and company would realize that the root domain also should rank well for SUV.
Anyone ever test this?

Great question and from what I have seen, I'd say it does, though I have no empirical evidence to support this as I have not tested it directly.

I've seen pretty compelling evidence that it does, on Google at least. It's mostly to do with local relevance, and the iterative nature of ranking calculations, rather than being a concious "design feature" though. you can think of it as an emergent property of relevance scoring / LocalRank

My understanding from attending Bruce Clay's SEO Toolset training, that a % of page rank for the anchor keyword does get passed "up" from internal pages.
