What ads show up doesn't necessarily tell you a thing about that individual user, because the networks use aggregate site as well as individual habits. I've had ads for things I've never looked at show up on my forums because some other users on the forums might have looked at them. You have to go to the ad company's server side to know the true picture of any given user.Your fingerprint within network leaks to website via cookies set within your domain by adnetwork's JS and querystring set on iframe inserted by it (and if you are running ads yourself, from ads pointing to your site).
Once you have fingerprint, you just query same endpoints ads do from serverside and look what ads show up. Thats it, no need to back-end access to network's data.
