That sounds like the kind of thing I envision.

Yes, no personalized data collection. Both sides of the ad transaction would need to track something if the placement had some kind of impressions or click-through payment system. It's been a while since I've managed a website, but I think most of that can be handled with pretty basic logging that has existed since before micro-targeted advertising was even conceived.

For a simple placement contract like we have with what few newspapers remain, the ad supplier could assess the value of the placement for themselves using standard referrer logs. Not paying its way? Don't renew the placement.
