Ad Unit Relevance

How Long Before the Ads Become relevant?

I recently had to change the Adsense Ads from one account to another (after transfer of ownership of the site).
Since the change the earnings/click through rate has dropped dramatically because less relevant Ads are being displayed.

How long does Google take to 'tune in' the right Ads?

It's just the theoretical speculation and only Google knows how it really works but…

1. It cannot be less than a week because it’s the smallest natural period when the pattern may repeat.

2. It cannot be less than 10 clicks for pattern (better 100) because otherwise no meaningful statistics is possible.

3. Since the adds are now irrelevant it is possible that Google tries again to determine the topic of the site and pages. Judging from the sandbox effects and assuming that the time is limited by the Google calculation power , it may be about couple month.

So the estimation is: between one week and the couple of months.
