PR doesnt affect the frequency of googlebot crawling ur site lol, they come when they want or when they are forwarded by a link to your site from another.
I don't think that PR matters much now-a-days. My website www.enamul.info is on Google's 1st page for key phrases craigslist posting tips & craigslist similar posting but it has zero PR. Content is most valuable I think.
PR is not Important for Blogs/Sites atleast I think so but PR is very important for Directory Owners PR doesn't mean anything to SEO, Content is King
Your PR does effect the frequency of Google bot. The higher your pr the more you should get crawled (not the only factor).
it still work as part of considering your SERPs but not that very important. it also can drive you some revenue if you got some respective PR.
I think PR is important but not something you always need to stress about. The way I view it is that if your site is just as relevant as your competitors google will likely give you a higher ranking if you have better page rank. It is also a good way to measure how well your internal link popularity is with google. If PR is n/a on internal pages google has not indexed these pages.
PR only gives an idea that the site is considered a decently popular site it is only one part of the algorithm. It measures one aspect of popularity used by Google overall.
Somehow important, if you want to sell links space and if you want to exchange links with other sites.
I think it depends on how you view and what you do with PR. For link sellers, PR is one of the most important advertising tool. As for getting ranked high in G SERP, PR is not as important as it used to be. But Google still uses PR, so you can't ignore 100% as a ranking factor. Just because it doesn't seem reflect to the position in G SERP, it doesn't always mean PR is useless.
PR or Page Rank is an indication of a sites popularity... the higher your PR is,, the more popular is your site!
it's my belief that pr doesn't have a direct effect on rankings, but there's a strong correlation between many of the things that give you high pr and good rankings. hope that makes sense to you.
Its really an advantage if your site has a PR because many site want to link with you or want to buy link with you.
