Frequency Capping in Google Ads

How to stop the same person seeing your ad over and over, where the setting lives, and why Google will not tell you the one right number.

Definition

Frequency capping is a Google Ads setting that limits how many times one person sees your Display or Video ads. You set a number of impressions per day, week or month. Display campaigns can cap at 3 levels: campaign, ad group or ad. Video campaigns cap at the campaign level only.

Also called: frequency cap, impression cap

How Frequency Capping Works in Google Ads

Frequency is how many times one person sees your ads in a set time. Google defines it as "the number of times a user sees ads in your Display or Video campaign over a given time period."

A frequency cap is the most you allow. When a person hits it, Google stops showing them that ad until the time window resets.

It only applies to Display and Video ads. Search ads do not have a frequency cap, because they show when someone searches, not while they browse.

Display and Video Caps Work Differently

Google spells out the differences on its definition page.

One Video detail catches people out. Inside a Video campaign, in-feed, in-stream and bumper ads all count toward its cap. Say the same video also runs in a second Video campaign. Views of it there count toward the first campaign's cap too, but only in-stream and bumper views.

What Is a Good Frequency Cap?

There is no single good number, and Google does not publish one. A number from someone else's blog was set for someone else's store.

Here is how to find yours. Start with the job of the campaign. A remarketing campaign that chases people who left a cart can live with a higher cap, because those people already know you. A campaign that shows you to strangers needs a lower one.

Then watch two things over a few weeks: how often people see the ads (Google's reach and frequency reports) and what each extra impression earns. When more impressions stop bringing more sales, the cap is too high.

Display Campaigns Are Moving to Demand Gen

Google is moving Display campaigns into Demand Gen, starting with a migration tool in June 2026. Check your caps after you move a campaign, because the campaign type changes even though the Display Network does not.

Store example

Example: A Skincare Store Caps Its Remarketing

Made-up numbers, to show the method. A skincare store runs a Display remarketing campaign to people who viewed a product in the last 30 days.

With no cap, some visitors see the ad dozens of times a week and a few email the store to complain. It sets a cap of 3 impressions per user per day at the campaign level.

Four weeks later it compares sales from the campaign before and after. Sales held steady while impressions fell, so the money it saved was going to people who had already seen enough. It keeps the cap and tests a lower one next month.

Common Mistakes

  • Looking for a frequency cap on Search ads

    Frequency capping is for Display and Video campaigns. Search ads show when someone searches, so there is nothing to cap.

  • Copying a number from a blog

    Google gives no universal cap. Set one, measure sales per impression, and adjust for your own store.

  • Capping Video at the ad group

    Video caps can only be set at the campaign level. Display caps can go on the campaign, ad group or ad.

  • Forgetting other Video campaigns count

    In-stream and bumper views of the same video in other Video campaigns count toward the first campaign's cap.
