I have a site that has a home page of PR5 and I don’t know why? I think my home page should have a lot higher PR but I have no idea what else I have to do to make this happen. Here is a brief info about the site. It is 5 years old, never being penalized, banned etc by SEs. Google shows 11,800 back links (and they are a lot more) that are not only internal but from thousands of external sites as well. No linkfarm sites, noting illegal deployed on the site (cloacking etc). Many of the external links are from well known news sites with numerous pages of PR8 and PR7 all pointing to my home page. There are many external links pointing to internal pages as well not only the home page. Google has indexed about 800,000 pages from the site and all of them (obviously) have a link to the home page. Yet this page has a PR5 and has had it for more than a year despite the fact I have added content and more external sites have links pointing to this very home page.
If anyone has an idea, I would appreciate. I am going crazy and don’t know what I have to do more to increase the PR or what am I dong wrong? I know many sites with 40 - 70 externel links and having PR6 or PR7?
