Mediabot
From Wikipedia the free encyclopedia, by MultiMedia
Mediabot is the name given to the robot that Google uses to crawl
webpages for purposes of analysing the content so Google
AdSense can serve contextually relevant
advertising to the page.
Mediabot visits those pages running AdSense ads
that have not blocked its access via a robots.txt file and it's a Google
recommendation that webmasters specifically add a command to their
robots.txt file granting Mediabot access to the entire site . Here is how
to do it
User-agent: Mediapartners-Google*
Disallow:
The Mediabot identifies itself with the user agent string "Mediapartners-Google/2.1".
The Mediabot revisits pages on a regular, but unpredictable basis. Changes
made to a page therefore do not immediately cause changes to the ads
displayed on the page. Note that ads can still be shown on a page even if
the Mediabot has not yet visited it, in which case the ads chosen will be
based on the overall theme of the other pages on the site. If no ads can be
chosen, public service announcements are displayed instead.
