@res260 @bagder i think that non tracking ads could work better than tracked ads.

For tracked ads, two weeks after buying a fridge online I still see ads for fridges... That's not going to get then sales.

Serve ads based on the content of the page instead. Am I looking up a microwave give microwave ads on that page.

There is a reason there is more beer commercials on TV during soccer matches than during Planet Earth documentaries. Its what people are interested in at that time.
