Anyone know how to change which Adsense ads get displayed?

Adsense theme change

[casper53]

I know, it's all about the theme of the page and the keywords, but what sections of the html, exactly?

Here's the deal. I am trying to get higher paying keywords to be displayed on <snip>, but as you can see right now it is showing ads related to the keyword "<general widgets>". I want to change this theme. I want this page to show ads related to <specific widgets> (or one of those 3), and I've changed the meta tags and added these keywords to the body. But it still shows "<general widgets>" ads.

I need to know how to change the theme of my page, and what Google looks for when they target ads? What part of my source are they looking at? And how long does it take to show the new ads once I successfully change the theme of a page?

Anyone...?

Thanks!

Type this into Google, and use it to see exactly what the spiders are seeing:

Should give you a good idea what to change and tweak.
