One of my sites, http://www.jaggedbladesoft.com is PR4, and has been for the last few updates (it was PR5 for a few months before that). http://www.jaggedbladesoft.com/desperate/ This page is PR5. Most of the other subpages are PR4. It always used to be that homepage was PR4, subpages PR3, then homepage hit PR5 and subpages hit PR4, then when the homepage dropped the others stayed where they are, except that link above which is oddly went to PR5. All link exchanges I do go to the hompage, and every subpage links back to the homepage. Whilst there are a number of game reviews and other misc site linking to /desperate/ out of my control, in general the vast majority of incomming links go to the homepage. Now, one thing I have cosidered is that some of my PR might be being filtered back to http://www.jaggedbladesoft.com/#. The reason some link to the # is because of Mambo on the SEO Friendly links module I use, basically I can't setup menu items to just link cleanly to http://www.jaggedbladesoft.com for some reason. However I always thought google would simply see http://www.jaggedbladesoft.com/# as http://www.jaggedbladesoft.com. And indeed if you look on google for the # page you get no results, whilst getting results for the url without the #. So I'm stumped, can anyone work out why my homepage isn't PR5 and why a subpage is? Thanks in advance!
Your subpage may have more quality links pointing to it I guess... If I read correctly, most of your homepage links are reciprocal? I don't think Google like them much... More isn't always "more", I would rather have 500 natural PR4 links than 2000 reciprocal PR0 links.
Well if all else is equal in a site then usually the main page will be PR5 for example, next level of pages PR4, then PR3 and so on. I have pages such as technical support which has no incomming links at all, that are PR4, and the main page is only PR4. So I'm not sure more links is the problem. Plus the root URL does actually have more and better natural links than any of the subpages.
