Is Google using pagerank in ad targeting?

[admin]

Q:
Hello
My first page the / one has sinds a few weeks a PR of 4, not very intresting but another page on my site has a PR of 5 and now Google is advertising herself; with 'adwords' and become 'adsense professional ads'.
I dont know how much $ this ads will deliver, not mutch because it's on a page that isnt visited often.
But do you think that google use Pagerank to push 'more or other' ads?
A:
My observation is that PR affects how deep and how often pages gets crawled by the bot.
The more frequent and the deeper (more pages) your site gets crawled, the better indexed you will become on Google.
The Better indexed you are on Google, the more visitors they will send you.
The more visitors you have, the more ads you will be getting and serving.
The more visitors, ads, impressions the more money you get.
