Pr?

What is the PageRank of your site? My site has a PageRank of 3, which I don't think is too bad...

I don't know so much about P3, but that's good. I think it's about the popularity of your site.

My site has PR4. And it gives me nothing

PR means google popularity, how much popular is your site.
PR deppends in sumary : how many backlinks your site has and pr of those backlinks:
for example 100 backlinks but those backlinks belong to sites with pr0 well not affect to much your site PR

5 backlink in pr6 sites, well I think your site will have pr4 at least in next google pr update.

at this time sounds good but i have another theory:

you know google sell adds right?
so like all bussines , google offer good sites where google will put your add.

hey buddy i have a good pr4 sites waitting for you, and of course google will earn more money than selling pr0 adds

so is posible that a site wich has 4 months old, began with pr0 and with alexa rank 0
has in 2 months pr4

also is not important to be online, becasue if your site has PR0 and is down 2 months, but your site has adsense, probably will have pr4 in 1 month.

so pr is not qual for everybody.

and adsense sites has preferences because google bussines

Thanx, I've cleared some things for myself from your post.

PR is good indicator about how good your backlinks are. I have few PR4 and lots of PR3 & PR2 websites.

is a Pr 1 better then a PR 2? how do you get all these backlinks is it just by emailing to a site and asking to exchange links with them?
