Optimized Ads

When do the best show?

HI,
I have been testing new copy and have discovered some that works significantly better(CTR) than my current copy.
If one lets google optimize ads, how long does it take for the new copy to be Optimized, i.e. get greater percentage of exposures.
thanks

First the new ad(s) needs to be approved. If it is, the speed in which the optimization works depends on how much better the new ad is. If it has e.g. a CTR of 10% and the old one 2% optimization an be very quick as in one or two days. When the difference is less it takes longer. Make sure you look at the daily percentages to see how the optimization is doing.

Remember that a good CTR is not the same as a good ROI though...
