BTW - not to wander off topic, but I had a real live Google rep call me a few months ago and left a very helpful sounding message (I wasn't home) asking if I had any questions and that they wanted to work with me to help optimize my Adwords account. Not sure if this was actually Google or some third party SEO scam. Anyone else get a call like this?
A year or two ago I had an Adsense Rep call us. She said make some ads bigger and convert all of our ads to image/text ads. I hardly noticed a difference. In fact, I tried analyzing it and the image ads paid worse.
