I'm increasingly freaked out by the relevance of ads I see across sites. For example, I receive a joke mail about planning a trip to Antarctica, and now I start seeing Antarctica travel ads across sites that use AdSense.
I am curious whether or not my privacy is controlled more tightly if I upgrade to a Google Apps for Business account. My assumption is that I (as an admin of the domain) would better be able to control which data Google has access to.
Hopefully someone a little more fluent in legalese has looked at the Terms of Use for Google Apps. If not, I suppose I will go ahead reading it.

The advertisements you see following you around are not connected with whether or not you have a Google Apps account, business or otherwise.
What is happening is that you're being remarketed to across the Google Ad Display network.
The cookies in your browser help the ad network track what kind of interests you've been viewing on other sites and find relevant ads to you. The higher the relevance, the likelier you are to click on the ads.
You can decrease the rate of these ads following you around by opting out using the Google Advertising Cookie Opt-out Plugin and deleting your cookies on a regular basis.
