I have 4 ads in an ad group in a few instances. For some reason, Google is showing an ad with a much lower CTR than 1 or 2 other ads way more. As in, 92% of the time. Why would they do that? And can I decide somehow which ads to prioritize? Or are my only options rotate and let google decide? Thanks!
Take a look at this thread... http://forums.digitalpoint.com/showthread.php?t=1514076 Make sure you go into your Campaign Settings and select to show ads evenly, instead of allowing Google to optimise.
