TL;DR
- Video campaigns cap frequency at campaign level only, by impressions, views or both, per day, week or month; Demand Gen campaigns do not support frequency capping.
- Impressions and views of the same video in other Video campaigns count toward the cap, and the stop applies only to in-stream and bumper ads in the auction.
- Target frequency in Video reach takes a weekly goal of 2 to 7 or a monthly goal of 4 to 12, and Google says it is not a frequency cap.
- Reach metrics cover at most 92 days, frequency distribution at most 31 days, and reach and frequency reporting can lag by up to 72 hours.
A frequency cap on YouTube sets a ceiling on how many times one person can see ads from your video campaign in a day, a week or a month. You set it at the campaign level in Google Ads, counted as impressions, views or both, and once a user reaches the cap Google stops showing that campaign to them. This guide explains where to set YouTube ad frequency, which campaign types allow it, how daily, weekly and monthly caps differ, where to read actual frequency in your reports, and what happens when the cap is too low or too high.
What a frequency cap is
Frequency is the average number of times one person sees an ad over a period. A frequency cap is the maximum you choose. If you set 3 impressions per week, a user who has seen the ad three times that week will not see this campaign again until the next period starts. The remaining budget goes to people who have not reached the cap, or who have not seen the ad at all.
There are two reasons to control frequency. The first is money: the fifth or tenth impression served to the same person usually does less than a first impression served to someone new. The second is perception: an ad that appears before every video makes people skip faster and can leave them feeling worse about the brand. Frequency that is too low has a cost too, because some messages need to be seen more than once before people remember them. So a frequency cap is not there to push frequency as low as possible. It is there to stop frequency going past the point you have decided on.
One thing to understand from the start is that a frequency cap is a ceiling, not a goal. Google does not try to make everyone reach the number you set. A campaign capped at 5 per week can easily show an actual average frequency of 1.5 if budget or audience size do not allow more.
Where to set YouTube ad frequency, and which campaigns allow it
Google Ads supports frequency capping in Video campaigns and in Display campaigns. Demand Gen campaigns do not support frequency capping. That matters because Demand Gen also serves ads on YouTube, yet you will not find a cap setting in that campaign type.
In Video campaigns the cap can only be set at the campaign level. You cannot set separate caps per ad group. The steps are:
- New campaign: go to Campaigns, click the plus button to create a new campaign, choose your objective and the Video campaign type, click Continue, then open Additional settings and go to Frequency capping.
- Existing campaign: go to Campaigns, open the Settings tab, select the Video campaign, open Additional settings and go to Frequency capping.
- Choose whether to limit impressions, views or both, enter a whole number, pick per day, per week or per month, and save.
In Video reach campaigns using Efficient reach or Non-skippable reach, the Frequency capping section sits in Additional settings as an optional step, with the options Cap impression frequency and Cap view frequency. The Target frequency option has no capping step in setup, because frequency is controlled by the Target frequency drop-down instead.
Display campaigns work differently. You can let Google Ads optimize frequency, which Google recommends, or set your own cap at the campaign, ad group or ad level. The menu is under Settings, then Additional settings, then Frequency management.
Two limits of Video campaign caps are worth knowing. First, if the same video also runs in another Video campaign, impressions and views from that other campaign count toward this campaign's cap, but only in-stream and bumper impressions or views. Second, when a user reaches the cap, the stop applies to in-stream and bumper ads in the auction only, so do not assume the cap controls every YouTube ad format.
Impressions vs views, and how day, week and month differ
An impression counts every time the ad is shown. A view counts when the user watches or interacts according to the rules for that ad format. An impression cap limits how often people see the ad whether or not they skip it. A view cap limits how often they actually watch. If the goal is to avoid annoying people, an impression cap is closer to the point, because skipping the same ad over and over is still seeing it over and over.
The interval you pick changes delivery a lot. An illustrative example, with made-up numbers only to show the logic:
- 2 per day. One person could see the ad up to about 14 times in a week if the budget is large enough. A daily cap stops heavy delivery within a single day, but it does not stop exposure piling up across the week.
- 4 per week. The system could use all four on Monday and then show nothing until the week ends. This suits always-on campaigns where you want to control the weekly total.
- 8 per month. The most flexible, and also the one that most allows frequency to bunch up at the start of the month.
For a short promotion of one or two weeks, a weekly cap is usually the easiest to read, because it lines up with the 7-day average frequency the reports show. For campaigns that run all year, a weekly cap combined with a look at 30-day frequency gives you both the short-term and the cumulative picture.
There is also a separate cap for video ad sequences. By default it is one sequence per person in a 7-day period, and it can be changed to one sequence per person in a 30-day period.
Reading actual frequency: Unique users and average impression frequency
The cap only tells you the upper bound. Actual frequency comes from the reach and frequency columns in the statistics table on the Campaigns page, which you add through the column settings. The main columns are:
- Unique users: the number of people who saw the ad, including co-viewers on connected TV.
- Avg. impr. freq. per user: total impressions divided by unique users. For example, 1,000 impressions across 200 people gives an average frequency of 5.
- Avg. impr. freq. per user (7 days) and (30 days): average frequency within a 7-day and a 30-day window. Google names the 7-day column and the frequency distribution as the preferred measures for frequency-focused campaigns.
- Frequency distribution 1+, 2+, 3+, 4+, 5+, 10+: how many people saw the ad at least once, twice, three times and so on up to ten or more. Use it to spot a small group seeing the ad very often behind a reasonable-looking average.
The reports have limits. The longest date range for reach metrics is 92 days, and frequency distribution is limited to 31 days or less. Data may not appear until the campaign reaches a minimum number of impressions and unique users, and reach and frequency reporting can lag by up to 72 hours.
If reported frequency is higher than your cap, the cap has not necessarily failed. In Display campaigns, only viewable impressions count toward the cap, while frequency reporting counts both viewable and non-viewable impressions, so the reported number can look higher. Reports also merge one person's exposures across devices, and the same video running in several campaigns can push the overall figure above any single campaign's cap.
| Metric | What it tells you | Decision it supports |
|---|---|---|
| Unique users | How many people saw the ad | Whether budget is reaching new people or circling the same ones |
| Avg. impr. freq. per user (7 days) | Average frequency per person in one week | Comparing against the weekly cap you set |
| Avg. impr. freq. per user (30 days) | Cumulative frequency over a month | Whether an always-on campaign is wearing people out |
| Frequency distribution 5+ and 10+ | The group seeing the ad very often | Whether to lower the cap or widen the audience |
What happens when the cap is too low or too high
Too low, such as 1 impression per month on a narrow audience, and the system struggles to find people who have not hit the cap. The visible result is unspent budget, fewer impressions than expected, and possibly a higher CPM as the system competes in auctions to reach the small group that remains. A message that needs repetition may not stick either. If budget is left over every day and the audience is narrow, a cap that is too low is one of the first things to check.
Too high, or no cap at all, and budget flows to the people who are easiest to win in the auction, often the heaviest YouTube viewers. The 10+ group in the frequency distribution grows, the cost of reaching new people rises without anyone noticing, and people who see the ad repeatedly skip it faster. This often does not show in the CPM or CPV columns, because the price per impression can still look cheap. You see it by comparing Unique users with the amount spent.
Another common mistake is running several campaigns with the same video and setting each cap separately on the assumption that they are independent. In practice, impressions and views of the same video from other Video campaigns count toward the cap, so a campaign set up later may barely serve. If you need to control frequency across several campaigns, merge campaigns that share a goal and set the cap in one place.
The way to find the right level for your business without guessing is to start with a moderate cap and change one thing at a time. Keep the Unique users, 7-day frequency and frequency distribution columns visible. After changing the cap, wait one to two weeks so the delayed reporting catches up, then compare business indicators over the same period, such as brand searches or direct visits to the website, rather than CPM alone.
How Video reach and Demand Gen differ on frequency
Video reach has three ways to reach its goal. Efficient reach aims to reach as many unique people as possible at a low cost, and can run bumper, skippable in-stream, in-feed and Shorts ads in one campaign. Non-skippable reach focuses on people seeing the full message, using bumpers of up to 6 seconds, standard non-skippable ads of 7 to 15 seconds, and 30-second non-skippable ads on CTV. Both bid on Target CPM and both let you set a frequency cap in Additional settings.
The third option, Target frequency, works differently. You choose a weekly frequency goal between 2 and 7, or a monthly goal between 4 and 12, and Google tries to get people close to that level. Google states plainly that this is not a frequency cap. Some people may see the ad more than the target in a week to offset people who see it less. These campaigns support one ad group only, should not use shared budgets, and should run for at least 7 days, with Google noting that flights of 2 to 4 weeks work best.
Demand Gen does not support frequency capping at all. Frequency in this campaign type depends on the system's optimization, the budget and the size of the audience. You can still read Demand Gen reach and frequency in reports, but if a hard frequency ceiling is a requirement for the campaign, use a Video campaign instead.
What this means for brands in Thailand
Viewers in Thailand watch YouTube in both Thai and English, and a campaign without a cap can quickly circle back to the heaviest viewers, especially when the audience is narrow, such as people in Bangkok interested in a single product category.
Seasonal campaigns around Songkran, New Year or double-date sales such as 11.11 tend to spend heavily over a short window. If the daily cap is too low, budget may go unspent on the days that matter most. With no cap at all, the same people may see the same ad many times in a few days. Planning a weekly cap that matches the campaign window, and preparing several versions of the video, helps reduce fatigue without cutting frequency.
Brands running Thai and English videos in separate campaigns should remember that if they use the same video file, the cap is counted together. If they use different files, the counts are separate, and people who understand both languages may see both versions, so the total frequency that person sees will be higher than either campaign's cap.
Frequently asked questions about YouTube frequency caps
Can I set a frequency cap per ad group on YouTube?
No, in Video campaigns the cap can only be set at the campaign level. If you need different caps for different audiences, split them into separate campaigns.
Can Demand Gen campaigns cap ad frequency?
No, Demand Gen does not support frequency capping, even though it serves ads on YouTube. If you need to control frequency, use a Video campaign such as Video reach with Efficient reach or Non-skippable reach.
What is the difference between Target frequency and a frequency cap?
Target frequency is a goal the system tries to reach, while a frequency cap is a ceiling that should not be passed. Target frequency lets you pick a weekly goal of 2 to 7 or a monthly goal of 4 to 12, and some people may see the ad more than the target.
Why does my report show frequency above the cap I set?
Because the report and the cap count differently. Reports merge one person's exposures across devices, in Display campaigns the cap counts only viewable impressions while reports count all of them, and the same video in several campaigns adds to the total.
Plan frequency before you launch
A good frequency cap comes from deciding in advance how many times one person should see the message, then using reports to confirm it. Relevant Audience's YouTube ads service defines audiences, formats and funnel structure, sets up conversion tracking, and reports in Thai or English. If you run YouTube alongside Search, see Google Ads management, and if you also need to control frequency on banner ads, see display advertising.
