AdSense Googlebot vs. the "Real" Googlebot

How to tell which logged crawls effect your rankings?

I have a ton of googlebot sightings in my logs, but I think that it is mainly because my site is a search engine with dynamically created pages, and AdSense ads on most pages. Since most searches are unique and generate a unique page, within seconds of a search the googlebot comes calling, reproducing the search and search terms.

My question is: Is this googlebot just checking the content for the purpose of targeting AdSense ads, or is it also using the information for relevancy ranking in search results? In other words, are there two googlebots or one, and if there are two, are they talking to each other?

Hello layklynn,

Welcome to Webmaster World!

You have googlebot, and you have mediabot. Supposedly, mediabot does not 'talk' to googlebot. I beg to differ, but that's a whole new discussion ;)

I was under the impression that you were not allowed to run ads on search engine resuts unless it's site search. In other words, no outgiong links in the results.

Glad to have you on board at WW!,

adsense in a searchengine has no use unless you generate large quantities of searches with the same keywords.

As long as mediabot hasn't fetched the page it will diesplay the promotion banners which bring in no revenue.

One of my friends with a similar page setup as you is running banners on the search results and google adsense on his content pages.

He is doing fine lately but always complaining the clickthru on the ads in the searchengine sections are low.

Thanks for the response. I guess "search engine" was not the right term: I have a database of information that users can search and produce tables of search results. It's not a search engine a la Google.

If I ignore googlebot visits that have "Mediapartners-Google/2.1 (+http://www.googlebot.com/bot.html)" then I guess the rest are "real" googlebot visits. Right?

mars: Thanks for the reply. I have a lot of unique searches and of course some that repeat. I cache my results with jpcache for five days, so I can see how many different searches are made, many with misspelled query terms and the like.

I'm _pretty_ sure I get non-public service ads most of the time even with queries I think are unique. I think that with multi-term queries, if any one of the words match (or perhaps if theres a substring match), AdSense will send relevant paying ads. Anyway, we should probably discuss this in the AdSense forum.
