Which metric is used to cap ad exposure to a user to once per day on Facebook or Instagram?

• A. Daily Unique Reach
• B. Link Clicks
• C. Reach
• D. Impressions

Answer: (A)

Daily Unique Reach tracks how many distinct people see your ad in a single day, counting each person at most once for that day. This is exactly what you need when you want to cap exposure per user to one impression per day, because it prevents multiple views by the same person from inflating the daily count. Impressions would include every single view, even if the same person sees the ad multiple times. Reach counts unique people over a period, not per day, so it doesn’t enforce a daily cap. Link Clicks measure actions taken rather than exposure, so they’re not about how often a user is shown the ad.
