Adsense Experiment

Don't know if this will help anyone out there but... here is what I have recently found out to be the order of operations for ads served by google on my sites.

Case: Relevent Ad not found for that particular page.
Result: Serves up an ad is deems appriopriate for that domain. This is believed to be based upon previous ads served on that domain before.

Case: Relevent Ad not found for that particular page, AND the domain has not served google ads before.
Result: It throws up charity ads. Ads for various charities around the world.

I just thought this was interesting... hope it helps someone.

 

I noticed this on my site too, I created a page that was not in the roor directory, and had a random filename, and the Google ads showed the exact same ads that where shown on my main index page.

the adsense spider should crawl new pages pretty quickly and should have relavant ads within a couple hours or so

 

I have just put Adsense on a site and it seems that the site is not spidered by the Adsense (Mediapartners-Google/2.1) bot in the same way as Googlebot works.

It appears that when the page with adsense on it is displayed to a user the adsense bot quickly requests the page if it does not have it cached already. then it shows the ads. I was amazed how quickly it can process the page. You can notice the page requests if you use the Adsense preview tool (and have access to the website logs).
