Even though advertisers are the ones paying, we are the one doing the service. My site is one of the largest in my topic, and we are the largest one who uses adsense. All other sites, that do what I do, depend on paying reviews or paying members. So if I stop running adsense a 100 small junk sites will get all those ads. Say what you want, but that matters a lot. I've started running paid ads this morning. We tripled our earnings a couple months back by doing this. I want google to be 1/3 of what we make, but at this point it doesn't make sense even to keep them on the site if the earnings go any lower.
This is like working with a company, the company makes you a 1/2 million or more over a couple year period, and then you decide to change the rules on them? Open your pay check and boom, less money? It's not right. We are going to paid ads too. What we need is a PPT ads. That's Paid per time, just like newspapers and magazines and television. PPC, PPA are like going door to door, it's never going to be stable.
