PR Pie?
What is PR Pie?
PR Pie is what I as well as some search engine marketers use to metaphorically describe how distribution of PR works.
If you have too many links coming from one page on your site, each site being linked to will receive less of a rank boost as more are added. Also having too many links from your site in the first place can negatively affect your PR period.
So lets say you have 2 link pages each with a PR 5, you have 20 links on 1 page, and 1 link on the other. The link by itself is getting the full PR boost of linking to your site while each of the other 20 receive about 5% of the PR5 boost.
As a rule of thumb I suggest not having more than 20 sites being linked to from any of your link/resource pages. Of course this is a lot harder to regulate when owning a blog.
