darkmage, good post. There are couple of other points, like the "location of visitors "one raised already, sources of your traffic would be another. What competing offer I have on my site also affect both the ads shown on my site and the CTR.
It happened as a result of broad based ads last Novemeber and again with the Smart Pricing formulas in April.
Agreed. But it does not happen on a week by week, or publisher by publisher basis that some here claim. Changes are an essential part of doing business on the web. Adsense would be remiss if it did not keep making changes with a view to improving the overall program. Some may lose and some may win. In March this year (April?) some publishers saw their earnings jump.
Is Google capping our average income to feather their own bed?
Hmm. There is no evidence of course but I look at the influencing factors. Adwords advertisers are not exactly being treated like gold. Google is advertising for more publishers. There are other points suggesting that if Google wants more of anything, it's publishers they want. They'd hardly be likely to try and upset the existing ones.
There is no conspiracy though.
