Managed Ad Ai will monitor your ads and pause an ad based on the criteria you input and even rebuild the ad automatically for you to try and get a better result. You will find this feature when you go to deploy and ad on the final step. Here is a break down of the settings:
1. Pauses the ad when cost per lead on the ad exceeds the inputted value.
2. When this is turned on it will build a new ad with the same image and copy as the original to see if it can get an improved result.
3. When this is turned on it will rebuild the ad with a different image and ad copy.
