On every other adsesne related ppl talk about High Paying Keywords always .. But sometimes I Wonder do ppl really put those keywords on those sites ? Does that Increase CTR as those ads will be unrelated to content right ? So does it help to just find High Paying Keywords and add those keywords on your site ?
With adsense you cannot pick keywords, Google picks them, and your website has to be related to them. So if you want high paying keywords then you need a website that is completely related to it.
