Are you running display ads?

If you are, then setting a frequency cap can optimize performance and also reduce the chances of your ads becoming annoying (especially if you are using remarketing).

You can use the Multi-Channel Funnels reports inside +Google Analytics to help determine a frequency cap for +Google Ads: https://www.youtube.com/watch?v=rCSOn0tvS8c
