The frequency cap for a brand limits the total number of times a unique device sees an ad within a specific period of time. This limit applies to all ads in the brand's groups and campaigns.
Group frequency caps and campaign frequency caps still take effect, but setting a frequency cap at the brand level gives you more control over the amount of impressions that you show to a single device. By limiting how many impressions you deliver to a single device, you can be more efficient with your spend.
