Ad industry person here. It's not really aggregate data in the sense that any records about you are still individually separated. You're not anonymized by getting mixed into a bigger pool of data points. The usual rule is that the buyer won't get your records by name but will know more or less where you live, how old you are, political leanings, hobbies and interests, etc. So you have some anonymized ID number or set of cookies attached to you. However, if you think about it, from the perspective of the advertiser your name is one of the less valuable things about you. So... you might be anonymous by name, but the name thing is a bit of a red herring.
