Frequency Cap
A frequency cap limits how many times one person sees your ad — but only inside one platform's walls.

A frequency cap is a limit you set on how many times a single user sees your ad within a defined time period, used to prevent overexposure and ad fatigue.

What is Frequency Cap?
A frequency cap is a guardrail. You tell a platform "show this person my ad no more than X times per day or week," and it throttles delivery to stay under that ceiling. The goal is to avoid burning out an audience and wasting spend on people who've already seen the message enough. The catch is that every cap lives inside a single platform's walled garden. Meta caps within Meta, Google caps within Google, TikTok within TikTok. None of them can see the others. So a user who hits your cap of three on each of three platforms has actually seen your brand nine times — and no platform knows that. This means total cross-platform frequency is effectively uncontrolled. The per-platform caps feel like control, but the real number — how many times a real person saw you everywhere — is invisible unless you unify the data yourself.
How Frequency Cap differs across ad platforms
Meta
Meta applies frequency caps automatically on reach-and-frequency buys and offers limited manual control on auction campaigns. Caps only count impressions served within Meta's own properties (Facebook, Instagram, Audience Network).
Google / DV360
Google Ads and DV360 offer more granular cap controls, including caps across campaigns and per-channel limits within Google's ecosystem. DV360 can cap across the inventory it buys, but still can't see impressions delivered by Meta or TikTok.
TikTok
TikTok provides frequency cap settings on certain buy types, scoped entirely to TikTok inventory. Like the others, it has no visibility into how often the same user encountered your ads off-platform.
Common Frequency Cap misconceptions
Setting a frequency cap on each platform controls how often people see my ads overall.
Each cap only governs one platform's inventory. A cap of 3 on Meta, Google, and TikTok can still add up to 9+ exposures for one person, because no platform deduplicates against the others. Overall frequency stays uncapped.
A lower frequency cap always means less waste.
Cap too low and you can starve campaigns of the repeated exposure that drives consideration and conversion. The right cap balances against fatigue, not just minimizing impressions — and it should be set with cross-platform totals in mind.
