Does making changes to your landing page start your quality score over or something? I got a keyword down to a very low bid, changed like 1 word on my landing page all of sudden my bid shot up. Anybody have any experience with this?
I suspect it takes Google's algorithm a little while to start "trusting" a website and even if you make only minor changes it has to be re-analyzed. Why not split test with new campaigns, saves you killing off your current ones.
