I would say that my best advice is that you need to make sure that the traffic going to your page actually would WANT to click an ad. You can't just pump a page with traffic and expect to see a high CTR or eCPM.
I believe there is no such thing as "a single most important Adsense tip" because just like cooking there is no such thing as "a fresh fish/meat" without various ingredients. One has to prepare nice dishes for the Adsense’s spiders for them to enjoy and tell the rest of the world about those dishes.
Hi ainmohd, I think you are right. But I just wanna pull out what everyone thinks about working with Adsense, everyone is special so each one of us should offer something different according to our past experiences.
