By "lot", I mean, that sometimes, there can be 100 links in one page of 3000 words.
JorgeV... too many internal nav links, whether in-line or from global drop down mega-menus, etc, will dilute both the value and the "meaning" of link-related signals transmitted by your individual links.
The "classic" formulation of PageRank (PR) suggests that on a page with "n" outbound internal links, each link will have one-nth the value of the PR available from the page to distribute to the rest of the site. Some models of PageRank suggest that links from different areas of a page might carry more "weight"... but, to keep discussion simple, let's gloss over this for this particular discussion.
What is important in your question is that on a page with, say, 20 internal nav links linking to other pages, each link will transmit roughly 5 times the value of a link from a page with 100 such internal nav links. Again, I'm going to gloss over what kinds of factors the links will distribute, but the point is that if you're counting links on a page, link value per link must necessarily be lower on a page with more links than on a page with fewer links.
The type of site to a large degree determines its nav structure. Where a site might be receiving its inbound links from other sites also will affect its structure.
Nav structure also inevitably relates to how a visitor might use the site. While lots of links on a page gives the user lots of choices, it might give too many choices, which might confuse both Google and the user
Additionally, a site like Amazon, with a huge number of inbound links, is able to be larger because it can attract more links than most sites, for a multitude of reasons.. That does not mean that a site can simply add a lot of pages and expect to do what Amazon does.
Additonally, your word count on a page doesn't determine how many pages a site can can support. The popularlity and scope of your content (as reflected in your inbound linking) determines that.
It's been so long since I've seen this discussed that I'm thinking that many SEOs and designers might think that it no longer makes a difference. I think that it does. I'm curious what thoughts others have.
