Newbie Question-How does Adsense work?

Hi all,

I was wondering if someone could tell me how AdSense works in regards to providing context based ads?

Does Google scan a requested web page from your site before it is sent to the readers web browser?

Cheers

When you insert the Google AdSense JavaScript into a page, the Google AdSense bot queries Google every time a user accesses the page.

If Google doesn't know what the page is about, i.e. the page is new or the page has changed, Google AdSense will send it's bot over to check the page out.

That looks like this in your web server logs:

64.68.83.29 - - [18/Aug/2004:22:30:38 -0600] "GET / HTTP/1.1" 200 6529 "-" "Mediapartners-Google/2.1"

Code (markup):

Once Google AdSense knows about the page, it selects appropriate ads to display to the user each time the page is viewed and the AdSense JavaScript is executed.

 

Thanks Will for your time and effort!

Cheers

..... until ADS has determined the content on a page and related it to potential advertising so called "public service ad's" will be shown as placeholders.

The mediabot is usually on the page within minutes of serving the page with the ad code on it but it can take a while to show targeted ad's.

It also does not do anything to your positioning but seems to use "intelligence" already available from generic g crawls, at least that is my experience, because once your pages (content theme) are known ADS show relevant content almost immediately.

Don't forget there is a tool here where you can check what may be shown on your pages. (Tools - view adsense for url)

I've seen the media bot instantly produce a result just after a page has been created (On a search request).

The page content is there, then the adsense appears almost instantly.

That just seems real quick to me.
