If your CTR is above 0.020%, then you are above the stated average. That doesn’t mean that this is as good as it gets or that you should be satisfied. As we’ve mentioned before, in our businesses, we pull any ad that has a CTR below 0.09%—it just doesn’t produce enough of a return. Certainly, keep an eye on your CTR and start creating new ads with different (but similar) photos. Test a few ads at a time, with the goal of getting a higher CTR and conversion rate. Try different photos first, then different headlines.
