How soon google updates its Ads?

I have changed the title and Meta tag keywords

[conjo_guam]

Hi all,
One of my website's heavily used page is dynamically created. This is where i have a potential to make some money.

I did change the title of the page and added Meta tag Keywords to suite the content of that page.
How much time google takes to re-read the content of that page and title to direct relevant ads?
As of now, i see irrelevant ads on that page.

Are there any other optimization techniques to improve the ads from adsense?

I also read that, dynamically created pages are not that good for adsense ads?
Is that true?

Thanks again

Were you able to find your answer? I'm interested in this as well.

As far as I know, the mediabot (for Adsense) won't revisit the page just beacause you change the page. Revisits can take some time to happen because of that.

Changing the adblock code might draw the mediabot back faster. You can always change the adblock back to the way you have it now after the mediabot visits again.
