I’ve managed more than $10 million in YouTube ads. Here’s something Google won’t tell you.
Controlling how many people see your YouTube ad, and how often, isn’t as easy as Google makes it sound.
That’s because YouTube is a mix of people who are logged in and people who aren’t.
The Problem With Frequency on YouTube
Frequency capping is meant to stop the same person seeing your ad too many times. You set a limit, say three views a week, and Google is supposed to stick to it.
But Google can only reliably count views for people it can identify. That means people signed in to a Google account.
Plenty of YouTube viewing happens without a sign-in. Smart TVs, shared devices, work browsers and private windows all make it harder to tell one viewer from another.
So when your report says people saw your ad three times, treat that as an average, not a fact. Some people saw it once. Some saw it ten times.
Why Does This Matter?
Every impression you pay for beyond the point where someone has got the message is wasted budget.
Uneven frequency costs you in two ways:
- Over-served viewers: Some people see your ad so often it stops working, or starts to annoy them.
- Under-served viewers: Other people in your audience never see it enough to remember your brand.
On a large YouTube and Google Ads budget, that gap adds up quickly.
The Fix: Run At Least Two Campaigns
Experienced media buyers get around this by splitting the job across a minimum of two campaigns.
- Campaign one, audience building: Its job is to reach people and build an audience of logged-in YouTube users who have engaged with your videos.
- Campaign two, the real campaign: This one retargets that audience with the ad you actually want to run, with your frequency cap applied.
Why This Works
By retargeting an audience, you force Google Ads to find logged-in users.
YouTube audiences built from video engagement are made up of signed-in viewers, because that’s the only way Google can connect a view to a person.
And because they’re logged in, Google can count how often each one sees your ad. Your frequency cap stops being an estimate and starts doing its job.
The result is a campaign that’s more efficient and more effective. Less budget goes on people who have already seen your ad too many times, and more goes on reaching the people who haven’t.
Questions to Ask Your Media Buyer
If you’re running YouTube ads, ask:
- Structure: Is our YouTube activity running as one campaign, or split into audience building and retargeting?
- Frequency: What frequency cap are we using, and how confident are we that it’s being applied?
- Audiences: Are we building YouTube audiences from video engagement, and how big are they?
- Reporting: Can you show frequency for the retargeting campaign separately from the rest?
If your media buyer isn’t doing this, ask them why.
