Back when I rand ads on my website, the click through rate was horribly low, and that's what the advertising agencies used to demand very low rates for displaying ads.
The strategy everyone who hates ads has adopted is to never click on ads, and as a result, a website displaying 10000 ads will probably only get a handful of clicks.
So the strategy I've adopted is to click on evry ad I can. Especially on websites I like. With such low click through rates, just one user can double or tripple a site's revenue, and by the same virtue double or tripple an ad agency's costs.
It only takes a few seconds to open every ad in a new background tab that I'll never see. And I get the benefit of helping a website I like, while costing the advertisers money.
I'd think it wouldn't take an incredible number of people adopting the same strategy before advertisers have to change their game.
