http://www.googlekeywords.net/ I just found this yesterday.....so it was news to me anyway. What this site is supposed to do is serve up a different high paying keyword each day. I suppose some people click on the adsense ads on the page. What has me puzzled (a common state of affairs for me) is how the adsense ads change when the content changes each day. For example, say I make a simple page about quittting cigarette smoking (topic "a"). I make sure to put in the right title and meta tags and so forth. I publish the page and, sure enough, appropriate adsense ads are displayed. Now I go back and change the same page to another unrelated topic, say mortgages. I am sure to change all the text and all the title and meta tags and so forth (topic "b"). I now push the topic "b" page back up the same url as the topic "a" page. Google continues to feed the topic "a" ads on the topic "b" page, at least for a while. What causes the ads to change and when will that happen? Any guesses as to how this high paying keywords page does it (uses the same url but serves different ads/topics each day?) Thanks.
I'm guessing they have the site built in PHP where they have variables in page title and meta tags, so they change dynamically every day there is a new topic to cover. With regards to Google ads changing, I have found that they change almost immediately based on page content, page title, etc. Vito
I think Google scans the page -- immediately on the page load. Then it caches it for later page loads. Maybe after 100 more page loads it will default to scanning the page again, just to check if there were any changes. So it doesn't really require the spider to go out and read the page again, the client's loading of the page acts as a spider... I mean triggering google to read/scan the page. hope that makes sense.
