    “..I can’t see anything that would explain the apparently large difference in CTR between these two ads which would cause the first to be shown so much more often..”

    Don’t let it get to ya. In my experience with AdWords, I have never been able to divine whether the “Optimize” feature even works at all! Typically, I will see 95% of impressions given to whichever ad was posted first. Every other ad plays a poor second fiddle, regardless of its CTR. A second ad could be grabbing a 20% CTR and it would *still* have just a fraction of the impressions that an original 1.5% CTR ad has. IMHO, there are programming problems with many of Google’s features … this being one of them.

    That being said, I very much enjoyed your attempt to explain it.
