How does Adsense know what to put on a page that is

created based on a dropdown form?

[HughMungus]

I have a page that has a dropdown menu with a bunch of RSS feeds from which a visitor can select and see headlines/summaries for each source. The RSS feed that appears to any given visitor is randomly selected from a (current) list of 5 or so.

It appears that the ads I'm getting now are basd on the Slashdot selection and they don't change if I select something else.

How will Adsense figure out what's supposed to go on this page? Will it just be random based on which RSS feed pops up when they visit the page?

Yes - AdSense is serving ads based upon the content when Mediapartners/Googlebot last read the page; not what the current viewer is looking at.

It sounds like the last crawl served up Slashdot from your random selection; so you are currently seeing ads based on that.

Thanks, d, that's what I figured. I wonder what those DNA gene sequencing ads pay. :D

Is the users' selection from the drop-down box being submitted via GET or POST?

If you're using POST, you could probably makes things work better by using GET; which will give MediawotsitGooglepartners/Bot some unqiue URLs to go at for each option from your list.

For the first page view; if you can do it you would be best off using a 301 redirect to the equivalent "GET" url for the random page.
