I am testing sevral versions of copy at the momment and although google says that it favours the ad with the highest CTR and will serve this ad more often, i am not seeing this. i have ads with double the CTR of other ads that are being shown less that the ads with the lowest CTR? how can this be ?

How you know that other sites have double CTR and your page is relevant to those keywords.

Also You may be seeing those ads but the higher paying ads might have a GEO targeted to some other region

How did you get this information?

I never knew that!

i do not geo target ads to different locations - they are all targetting UK. ALso i'm not on about other sites i'm on about Ads in my account that are under "ad variations" i have about 10 ads all running for the same campaign/ad group/keywords. Google is not serving the ad with the highest CTR in the ad group , is this a lot clearer now?

You have to go into your campaign settings and under the advanced options > Ad serving you need to select "Optimize"

it is

Interesting... I had that problem once and I just deleted all the ads and re-created them and it worked fine. It's a lot of work but you might be able to try that.

say that? yeah work work work
