Ok I'm almost embarrassed to ask this question but I've scoured the net and STM without coming up with anything so I must be doing something wrong. Anyway, here goes...
I'm looking to rotate ad images for a FB campaign (while maintaining the same ad copy) to see which images have a higher CTR. One way to do it is to duplicate an existing ad and changing the image only, but is there another way? eg. have several images rotate in a single ad?
I'm thinking the "duplicate ad" approach isn't ideal because effectively, your ads are bidding against each other? So if you're testing CTRs for dozens of images, this could to some degree impact the CPC (especially if everyone else is doing the same thing)?
Thanks a lot in advance!
Dynamic rotation of images inside a single ad? Not going to happen. Duplicating ads is the only way to do it. If you did change image you would also need to change ad URL, so, everything would now have to be dynamic. Your always going to be in an auction for impressions with many competitors including yourself. Don't get hung up on it and just test like your other campaigns don't exist.
Got it. Thanks, that was helpful.
