Google AdSense и robot.txt

Вот что пишет Google:

Robots

If you have a robots.txt file, remove the file or add the following two lines to the top of the file:

User-agent: Mediapartners-Google*

Disallow:

This change will allow our bot to crawl the content of your site, so that we may provide you with the most relevant Google ads.

мой robot.txt выглядит так:

User-Agent: *

Disallow: /admin

Disallow: /bin

Disallow: /db

Disallow: /download

Disallow: /htmlarea

Disallow: /icons

Disallow: /productdescriptions

Disallow: /productspecs

Disallow: /skins

Disallow: /src

Disallow: /xml

нужно ли что то изменить в нем ?

спасибо.
