How long does it take to get crawled by the AdSense Mediabot?

I'm hoping being crawled will help

[clickme]

I'm new to adsense and am wondering how long it typically takes Google to crawl my site? I just downloaded the Preview tool, and believe I can't see the site because my site hasn't been crawled.

Also, does anyone know if getting crawled will help with profits?

Your help is appreciated.

Thanks

Generall it only takes a couple of days for the site to be crawled, then It will happen countinously depending on how often you add new content make changes etc.

It normally happens within a few secs of an ad getting clicked.

I always thought that a page was crawled as soon as an ad was placed on it. I have been adding sites over the last few months and the ads seem to be on target from the get go.

I think initially they are based on either the rest of the site by broadly matching that content, and / or by url and filename. Once refreshed or clicked a few times (NOT BY YOURSELF!) then they get a more thorough looking at! And after some time depending on performance etc the best ads eventually "settle" on that page.

As far as I can tell...

Looks like my site must have already been crawled. I guess I still have lots to learn. Luckily, all of you nice folks are here to help.

Thanks

It seems to me that it is like Nitrous said. I've put up a few new pages, and initially, the ads are either off-target, or more often, on-target to other pages in my site, but after a day or two, the ads seem more targeted to the specific page.

It's fun to watch this stuff from day to day and try to figure this stuff out.

I just studied it at a new report from me.

Just seconds after a visitors comes to a new page, the mediabot comes to.
