Try viewing your site with Firefox with the adblock extension installed. Poof! No ads.

This is one of the issues I have with third party, javascript based ads. They are easy to filter out. So not only don’t you have any control of the content, but many people don’t see them.

In my first pass with ad sense I got a lot of ads for patent medicines and self-help sites. These are exactly the types of nostrums I would write against (if I had thought of it).
A series of emails back and forth to support, just reinforced my dislike for Google’s “smarts”.

See my two linked essays on google’s monopoly arrogance:

In addition Google gets the float for the ad revenue until they feel like sending you a payment. How much is that worth?
There needs to be a better way for small sites to receive some revenue from relevant ads.

I don’t think the long tail expects to get rich or retire off of AdSense revenue. I make more in one hour at my job than I do from one month of AdSense. But I make enough to cover my hosting costs, so that’s good enough for me. At least my site isn’t a money-losing venture anymore!

What you can also do is use different channels to see what ads placed on different pages or in different positions do.

You could also - and I hesitate to mention this - decide which format of ads and where they are based on, for instance, post number. Even posts get an ad at the top, odd posts get an ad at the bottom, etc. The goal would be to prevent ad blindness.
