> statistically significant?

Yes. Don't have the numbers in front of me and wouldn't share them if I did, but the change in my traffic was dramatic without dramatically affecting my earnings. (And I've been using this new approach since a few days after the New Orleans WW. It seems more stable than before.)

Sustainable as in "If I get down to 1 visitor will I be making an infinite amount of money?" No, probably not. :)

The real lesson was a sufficient number of poor quality clicks means a statistically lower chance of conversion and a discount of all clicks. So, I stopped chasing raw quantity of visitors and am far more picky. Plus, I handle ad placement more conservatively by only putting them where a click would be likely to convert.

As in all things, YMMV. :)
