Use Multiple Palettes… does Google automatically optimise performance? Does Google show the highest performing palette? bouncybunny msg:4189110 9:29 am on Aug 19, 2010 (gmt 0) I have been using the Multiple Palettes option in many ads for several years and have laboured under the impression that Google will automatically show the best performing version. But I recently realised that I can't actually remember reading anywhere that this is actually true. I can't find any reference on Google's site or blogs. Does anyone know?

I have never heard, and I always just assumed they rotated them. It's a good question, but I dunno if we'll get it answered unless we get an ASA again. I don't use it; I serve up alternate ad styles via PHP and assign a channel to each one, and that's how I control performance (why won't anyone click on green? it's my favorite color) bouncybunny msg:4189592 4:55 am on Aug 20, 2010 (gmt 0)
Yep. Indeed, I suppose I really should do some A/B testing, but I generally prefer to just let them get on with it. farmboy msg:4189681 10:11 am on Aug 20, 2010 (gmt 0)
If you have three color palettes rotating, say red, green and blue, the only way to see which performed the best was to have the same ad shown every time someone viewed the page - otherwise it may be different ads that are causing clicks, not colors. In my experience viewing my own sites, the colors seem to change on a planned basis but the ads are more random. That's led me to assume (a dangerous thing) the colors change based on repetition not based on which ad is performing best. FarmBoy rustybrick msg:4189727 12:18 pm on Aug 20, 2010 (gmt 0)
Seems random, see https://www.google.com/adsense/support/bin/answer.py?hl=en&answer=9981 "You can select up to 4 palettes that will rotate randomly."
