Google sense target optimization

[ernest1a]

I have never used Google sense, please tell how much can you optimize it. Please tell if is possible to do the following thing:

Let's say we have a social network site. Every user has own profile.

Is it possible to show on all pages to each user ads depends on user profile data (age, country, hobbies)? Those data are not shown on page where ads are displayed but in user settings page.

So can you send to each ad impression an information about to which data it should be related/targeted?

Thank you
