So they help people part with their money. Then, if I was an advertiser, I'd put my money elsewhere:
> For example, while Google users click on the first advertisement for search results an average of 8% of the time (80,000 clicks for every one million searches), Facebook's users click on advertisements an average of 0.04% of the time (400 clicks for every one million pages).
So? Advertisers pay per click or even sale, so they don't care the least how many people "saw" their ad before that. Some agencies even sell this as a "branding" side effect.
