I'm not sure what you said but if I shrink bitcointalk.org and then share that link and someone clicks it he will see dd and after that go to bitcointalk.org and I get paid for that.
Yeah, but what does that accomplish for the person visiting that link? The key to success is to hide something interesting behind the advertisement. That's the reason why many streaming websites or websites that feature an index of streaming services, use those ads to make money.
it's crap ads for crap money, you don't get fancy retargeting/keywords etc
