Which of the following describes the number of times a unique user will see an ad over a given time period?

• Reach
• Impression
• Engagement rate
• Frequency

Explanation:

Frequency refers to the number of times a single user sees an ad during a defined period. Using frequency capping—available in Display and Video campaigns—advertisers can control how often their ads are shown to the same user. In Display campaigns, advertisers can either allow Google Ads to automatically optimize ad frequency or set a manual limit at the campaign, ad group, or ad level. This approach helps manage impressions more efficiently and reduces the risk of ad fatigue among users.
