is Google using pagerank in ad targeting?

Found something intresting pagerank with ad targeting

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?

Google is advertising herself

You will probably find these ads are affiliates promoting the 'referal program' for Adsense. I would expect the value per click to rise over time as more people compete to get signups to Adsense.

I think that was your question.

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.

So excluding topic relevance & EPC, yes PR (among other things) plays an indirect role in the kind of ads you get and the amount of money you earn, hence the green color $$ of your PR in the Google Toolbar ;-)

Yes Hobbs is understanding my thinking... sorry for worse English,

But all my pages are indexed, i dont think PR has effect on how many pages google will index. From the beginning of my site Google liked my site structure and indexed everything... ( a little too much )

The only intresting find i would like to share with you is that you may get Better and more expensive ads when you have a high PR.

Maybe you knew that allready, im sorry then.

It sure does affect how frequent pages are crawled and the affects the cache update on the google servers, but that's another discussion another forum..

As for the earnings per click (EPC) being higher just because of its coming from a high PR pages, I don't think so, it has to do with the topic of the page, and how well this page converts visitors in the eyes of the advertiser among other things.

High PR (or perhaps the gross number of links to a page) does seem to encourage Googlebot to crawl more frequently and more deeply, but I'd be surprised if the Mediapartners bot looked at it. It would make much more sense to pay attention to (a) how many people actually view a given page, or (b) how often the page is typically updated.

I also doubt very much that PR is a factor in determining what ads to show. Why should it be? Google is trying to show relevant ads on behalf of its advertisers, not reward you for having a popular site.

[Hobbs]

agree to all what you said jomaxx, as for MediaBot, probably as they once told me, the AdSense team is very separate from the search engine team to maintain objectivity, so I would not be surprised if PR is ignored all together when placing ads on our pages.

[ska_demon]

I agree jomaxx.

As an example:

Pretend I have a site that is totally unique its field. There is no other site covering this topic or keywords. As the only site in its niche it gets loads of inbound links which gives it a huge PR of say 9.

Nobody bids on Adwords in this sector so when I put Adsense on my pages what type of ads will get served?

PSA's and other irrelevant low paying ads. Even tho I have PR9

Does that make sense? Sort of ;)
