Frequency capping

Frequency capping, also known as ad frequency control or ad impression capping, is a feature used by advertisers to limit the number of times a specific ad is displayed to the same user within a set period. This period can range from a day to a month, depending on the advertiser's goals and the advertising platform's capabilities.

Purpose of frequency capping

The primary purpose of frequency capping is to optimize ad delivery. It aims to strike a balance between achieving campaign objectives, such as brand awareness or conversions, and preventing ad overexposure. Overexposure occurs when users see the same ad repeatedly, which can lead to annoyance, ad blindness, and a decrease in campaign effectiveness.

Types of frequency capping

  • Hard frequency cap: This type of capping sets an absolute limit on the number of times a user can see a particular ad within a specified time frame. Once this limit is reached, the user will no longer see the ad during that period.

  • Soft frequency cap: A soft frequency cap allows some flexibility. It aims to limit ad exposure while still considering the user's behavior and engagement with the ad. If a user interacts positively with the ad, they may see it slightly more times than the cap suggests.

  • Viewable frequency cap: Some advertisers focus on ensuring that their ads are viewable to users, which means that the ad must be displayed on the screen long enough to be seen. Viewable frequency capping sets a limit on how often the ad is viewable to a user.

Benefits of frequency capping

  • Improved user experience: Frequency capping helps prevent users from being bombarded with the same ad, leading to a more positive and less intrusive online experience.

  • Cost-efficiency: Advertisers can manage their ad spend more efficiently by avoiding unnecessary ad impressions to the same user. This can lead to cost savings.

  • Ad effectiveness: By preventing ad fatigue, frequency capping can maintain ad effectiveness and engagement, increasing the likelihood of achieving campaign goals.

  • Brand perception: Overexposure to ads can negatively impact a brand's image. Frequency capping helps maintain a positive brand perception.

Challenges and considerations

  • Choosing the right cap: Setting the appropriate frequency cap requires careful consideration of campaign objectives, ad content, and user behavior. Too strict a cap can limit reach, while too lenient a cap can lead to overexposure.

  • Platform limitations: The capabilities of different advertising platforms may vary in terms of frequency capping options. Advertisers need to understand and work within these limitations.

  • User engagement: Advertisers should monitor user engagement and adjust frequency caps accordingly. For instance, if users are positively engaging with the ad, a slightly higher cap may be acceptable.

Frequency capping is a critical tool in online advertising that helps strike a balance between campaign effectiveness and user experience. By setting appropriate limits on ad exposure to individual users, advertisers can improve their campaigns' efficiency, maintain user engagement, and ultimately achieve their advertising goals while avoiding the pitfalls of ad fatigue.
