I have an eight year old site which has done very poorly in the SERPS the entire time I've been running it. Since earnings have been trivial, I figured I'd remove the ads and see what happens. Much to my surprise, the site is now at #2 of some 20,000,000 returns for the very same highly competitive keyword search that's never worked before. Interesting.
