The AB Testing for Ads optimization is a data-driven tool that helps you compare ads with statistically significant data in the same ad group. It helps you find ads that meet your business goals or contribute to the success of your advertising campaign and remove those that are not performing well with a single click.
Cost/Conversion is not a ratio that can be used to determine success and is not a percentage that can be used to determine the probability of success for an ad text.
If an ad or an ad group is not listed on the page, it is because they don't have enough data for the tool to make a recommendation. The system analyzes all active ad groups real time and only shows those ads and ad groups that have statistically significant results. If you want to view all the active ad groups in the account, try the turbo mode in this optimization.
The AB Testing tool compares ads with statistically significant data and shows you the losers based on the criteria you choose (Conv/Imp, CTR, Conv Rate).
When you have unselected highlighted ads, it means those ads are losing, but not based on the selected criteria.
