That's short and explains it. Thanks shockie.
I understand now that in order to make profit from Google Ads, I have to select a niche. A niche which sells expensive stuff so they afford paying a high PPC then develop a site around that niche this way I get targetted ads and higher PPC.
Shockie's answer is probably what I wanted to confirm. I am having a problem.. 2 choices.. I could choose a domain with extremely searched times and no ad score, or choose a domain with low search volume and high ad score.. (I think the second option pays more..despite the first one pays a lot of traffic)
But what traffic means If I can't convert it to cash.
It makes sense.. the more searched / popular terms are low ppc.. and the less searched terms are high ppc..did I get it right?
I would say for example.. a site about loans pays more than a site about hot girls.
One last, and important question.
Let us say I decided to choose Credit Cards as my upcoming site niche, how can I know the ppc that advertisers are paying in this category? "credit cards"
Hope you got my question.
Otherwise, it would just be a waste of time in development and so on.
