Thanks to a question by farmboy over at WebmasterWorld and the replies by RhinoFish I am taking a new hard look at my AdSense publisher behaviour.
Questions from an AdSense publisher
I sort of knew most/all that was said but it hadn't sunk in.
Read the thread, follow the citations/links, read some more. I suspect that this one thread will increase my AdSense revenue significantly. Perhaps yours as well.
if you can add a new layer of attention to your adsense thinking, and if you add lots of sections that aren't identical to your contextual structure, you will allow more bidders to chase you, from more angles. and in an auction, more bidders means higher prices, for you.
