I don't know how I can keep a user on a page longer

I didn't mean on your site - I meant on the advertiser's site. Smart pricing occurs, broadly, when ads are not seen as delivering value to advertisers. One measure of that is people accidentally clicking through to an advertisers landing page, realising it was a mistake and leaving immediately.

When doing anything with AdSense one of the primary questions should be "How will what I do improve the quality of clicks I send to my advertisers?". In the race to increase their CTR, that is all too often something to which AdSense publishers give little or no thought.
