Frequency cap

A limit on how many times one person sees a Display or Video ad in a period. Without one, a few heavy users can absorb a large share of impressions.

Why it matters

Without a cap, a small group who spend all day on one site or app can see the same ad hundreds of times. That money buys irritation rather than reach.

A cap spreads the budget across more people, which is usually what a Display or video campaign is for.

Where to find it in Google Ads

  1. Open a Display, Video or Demand Gen campaign, then Settings.
  2. Expand Frequency management or Frequency capping.
  3. Set a limit per day, week or month on impressions or views.
  4. Compare reach and frequency columns before and after.

An example

A remarketing campaign with no cap shows the same visitors an ad 40 times a week. Capping it at 5 per week cuts spend on those visitors and frees budget to reach more of them.

Common mistakes

  • Leaving Display and video campaigns uncapped.
  • Setting the same cap for prospecting and remarketing.
  • Setting a cap so low that nobody sees the ad enough to remember it.

Checks that look at it

  • Display Network: Websites and apps where Google shows image and text ads.
  • Video campaign: A campaign that shows video ads on YouTube and video partner sites, for reach or views.
  • Remarketing: Showing ads to people who visited your site or used your app before.

What frequency cap should I use?

Start with a few impressions per person per week for prospecting and somewhat more for remarketing, then adjust on reach and conversions.

Do frequency caps apply to Search?

No. Search ads only show when someone searches, so there is no frequency cap on Search campaigns.
