What is the purpose of a 'frequency cap' setting in a Twitch ad campaign?

The purpose of a 'frequency cap' setting in a Twitch ad campaign is to limit the number of times a single viewer is exposed to the same advertisement within a specified period. This is done to prevent ad fatigue and to optimize the overall effectiveness of the campaign. Showing the same ad repeatedly to the same person can become annoying and counterproductive, potentially leading to negative associations with the brand being advertised. By setting a frequency cap, advertisers can ensure that their ads are shown to a wider range of viewers and that individual viewers are not oversaturated with the same message. A frequency cap helps to improve the viewer experience, reduce ad waste, and potentially increase the overall ROI (Return on Investment) of the ad campaign. For example, a frequency cap might be set to '3 impressions per viewer per day', meaning that no individual viewer will see the same ad more than three times in a single day. This setting is crucial for balancing reach and frequency and maximizing the impact of the ad campaign.
