I guess there is no incentive in most markets. Facebook, etc make only a token effort to reject non-troublesome bot traffic.
[0] bots and other automated traffic which cannot generate revenue or human ad views
One rep I had known for years finally admitted the truth off the record. "Dude, we know," he said. "Everyone knows. But if we filtered it all out properly, our revenue would drop 40% overnight, and investors would have a meltdown."Yes, if you only count purchase/sale conversions
Maybe no, if you also count clickthrough and view conversions, perhaps even lead conversions sometimes (because fake sign ups are possible).
But you’re right. Purchase conversions are one incentive
I'd love to have an agent that goes online whenever I'm running low on toilet paper or something, browses all the stores and clicks all the ads, and automatically orders the best deal it can find.
