No, PR is page rank. PR is passed on by links. If you have 10 links on a page, a portion of the PR will be "passed on" through each link. Reduce the number of links and you will "pass on" more PR. Does that help?
Okay thanks. I think I got it. My home page PR doesn't drop by linking to other pages on my site. Here's another issue. I have a cgi-bin page with "noindex" robots tag, and the page has a PR of 3. I guess I thought that "noindex" pages wouldn't get PR passed on to them. Any ideas why this page got PR?
