CTV Frequency Capping 2026: The 3-5/Week Rule That Works

DRAFT — outline below, needs body expansion before publish.

Intro hook

Most CTV plans cap frequency at 7–10 impressions per household per week. Real 2026 performance data shows the sweet spot is 3–5. Above that, ad recall plateaus, brand sentiment drops, and you're paying for diminishing returns. Here's the data behind the rule — and how to set the caps correctly across DSPs.

The 3-5/Week Rule — what the data shows

• SpotlightIQ 2026: frequency capping at 3–5/week reduces ad fatigue by 22%
• Below 3: not enough memory built to move purchase intent
• Above 5: ad recall plateaus, brand sentiment scores drop
• Above 8: actively negative — measured drop in purchase consideration

Why traditional TV frequency rules don't apply to CTV

• Linear TV: passive, half-attention environment — needs 7–10 exposures
• CTV: full attention, audio-on, big screen — each exposure is worth more

How to set frequency caps in each major DSP

• The Trade Desk: campaign-level + ad-group-level cap setup
• DV360: insertion order + line item caps
• Amazon DSP: audience-level frequency
• StackAdapt: campaign-level with override

Frequency caps by funnel stage

• Awareness/prospecting: 4–5 per week
• Consideration: 3–4 per week
• Retargeting: 2–3 per week
• Converters (suppress): 0

The dayparting interaction

• Why 3–5/week doesn't mean 1 every other day — cluster around primetime
• Lookback windows: 7-day rolling cap performs better than 30-day

Common mistakes

• Setting frequency at vendor's recommended default (usually 10+)
• Not separating frequency caps by funnel stage
• Ignoring cross-device frequency (UID2 helps solve this)
