An advertiser notices that Pins are served too many times to the same audience. Which two steps should the advertiser take to help fix this issue?

When Pins are served too many times to the same audience, it indicates a high frequency. To address this, an advertiser should decrease or remove the frequency cap, allowing the system to serve ads to a wider range of individuals within the target audience, thereby reducing individual exposure. Alternatively, broadening the audience target by adding Interests expands the pool of eligible users, naturally lowering the frequency for any single user as the ad spend is distributed across more people. Creating niche audiences would likely increase frequency within those smaller groups, not decrease it. Increasing the frequency cap would exacerbate the problem. Creating a new ad group with a lower frequency cap is a valid strategy, but "Decrease or remove frequency cap" is a more direct action applicable to the existing setup.
