It seems likely that search engines — and Google in particular — regard some links as more valuable than others. And it seems very likely to me that they — and Google in particular — will tighten up the way they regard links. Because the search engines keep their techniques secret, the following practices may already be in use or could be soon:
- Links inside paragraphs of text are likely regarded as more valuable than links in large lists or links set apart from text.
- The search engines could compare incoming links with outgoing links, and downgrade a page or site if it appears to do a lot of reciprocal linking from link pages.
- Links pointing to a page inside a site might be valued more highly than links to the home page.
- Outgoing links concentrated on a few pages might be valued less than links spread around a site.

Why are Links so Powerful?
Links from other webmasters are viewed by search engines as unbiased third party votes.
Importance of Number of Links on the Page
Any page only has a certain amount of link popularity which it can redistribute to other pages.
