Adsense and Affiliate Marketing; both of them have been quite heart throb for webmasters across the world.
AdSense is very easy to implement and pays for the daily bread.
Affiliate marketing needs more research to find which product/service works better, it never gives regular income, but occasionally provides the butter and jam.
Agree, I am also concentrating on affiliates, although still running adsense simultaneously on most sites…Guess a lot of good sales flow out with the clicks (worth cents) on adsense, so the last 2 sites I’ve made do not have any ads and I’ll also remove them from 1-2 more sites, which have good affiliate earnings. However, for sites not precisely aimed at the right keywords, Adsense still works nice.
It depends on how to you know about selling and searching. Affiliate marketing requires us to learn the art of selling, while Adsense require us to be resourceful. In both cases, I think both of them are not easy. We can only make it not harder.
