Hi guys. I'm currently looking to start A/B testing on some of my ads.Hi guys. I'm currently looking to start A/B testing on some of my ads. However, the account already has 4 ads set-up in one ad-group - and all the ads have varying levels of success. For example - our ad with the most impressions in May had a CTR of 22. 27%, but a cost / conversion of $2. 25. Whereas another ad with a similar amount of impressions has a CTR of 7. 09%, but has a cost of conversion of $1. 56. (What's interesting is that some ads get similar amount of impressions, even though ad rotation is set to optimize). How do I determine which ad(s) to pause to start rotating new ones for A/B testing? And how many should I have running at the same time for best practices? I'm still quite new to all this - any information is highly appreciated! Thanks in advance.
