Hi, I have a high traffic site with adsense on it. I want to save in a txt file every 6 hours which adsense ads are being displayed. Is this possible with php or something like that? I can't even view the actual links if i check the source of my page. Maybe there is a commercial software available? Anyone can point me into the good direction?
No you cannot. How about incorporating GoogleAnalytics? I am planning to do that but I am lazy and don't want to pour over analytic data to discover gems. But that is the only way to go.
If you wait, you soon will be able to link your Adsense to your Google Analytics. I think they are slowly rolling it out to all publishers. Look at this http://uk.youtube.com/watch?v=UWxFqb5pa40
It isn't possible. When some ads show up depending on what country you are in, it would present a bias to your results.
I don't think there's an automated software around. I'm afraid it has to be done manually and add it to your list. Just install the ads preview tool and check out which type of ads that appear.
That is not possible. Google automatically displays them related to your content. If you change your content then you will get other ads. Don't try to target high paying keywords - its a common misconception that that will not get you the money you are looking for (sorry for linking to my own blog, but I explained it pretty well ;P).
