⚡ Quick Answer
Facebook frequency cap limits how many times one user sees your ad. Set it in Reach campaigns: typically 1-2 impressions per 7 days for awareness, 3-5 for retargeting. Conversion campaigns don't allow custom frequency caps in 2026 — Meta optimizes automatically with Andromeda, the new ranking system.
If you've ever scrolled Facebook and seen the same ad five times in an afternoon, you understand why frequency caps matter. Show your ad too rarely and you don't build memory; show it too often and you trigger ad fatigue, negative feedback, and rising CPMs. The sweet spot is narrow — and in 2026, Meta's Andromeda ranking system has changed where that sweet spot sits and who controls it.
For years, the playbook was: set a cap of 2 impressions per 7 days at the ad set level, monitor, adjust. That still works for Reach campaigns. But for the conversion-optimized campaigns most advertisers actually run today (Advantage+ Shopping, Sales, Leads), Meta has quietly removed manual frequency controls.
What is Facebook Frequency Cap?
A Facebook frequency cap is a delivery rule that tells Meta the maximum number of times a single user should see your ad within a defined time window. Classic format: "X impressions per Y days" — for example, 2 impressions per 7 days.
Frequency caps exist for one core reason: diminishing returns. First exposure has highest CTR. Second/third reinforce recall. By the fifth/sixth view, CTR collapses while CPM creeps up. Past a certain point, additional impressions actively damage brand perception.
Frequency cap is distinct from frequency (the metric) — average times each unique user has seen your ad. Frequency is observed; frequency cap is enforced.
How Frequency Cap Works in 2026 (Post-Andromeda)
Meta rolled out the Andromeda ranking update across all ad accounts during 2025. By 2026 it governs nearly every delivery decision — fundamentally changing how frequency works.
Different rules for Reach vs Conversion campaigns
- Reach campaigns — Frequency cap exposed at ad set level. You set X impressions per Y days, Meta enforces strictly.
- Brand Awareness — Folded into Reach in 2026; same controls.
- Video Views — Frequency cap available, but Meta optimizes for ThruPlay completion.
- Traffic, Engagement, Leads, Sales (Conversions), App Promotion — No manual frequency cap. Meta's algorithm decides.
- Advantage+ Shopping & Advantage+ App — Fully algorithmic; you cannot set any frequency rules.
Default behavior in Advantage+
Andromeda models a "fatigue curve" per user. If a user has seen your ad twice without converting, the model lowers their score and you won't win the next auction for that user. Result feels like a soft, dynamic frequency cap — but per-user and changes hour by hour.
How to Set Frequency Cap in Facebook Ads Manager
Step 1: Choose Reach campaign objective
Click Create, under "Awareness" pick Reach. If you select Sales, Leads, Traffic, or Engagement, the frequency cap field will not appear later.
Step 2: Navigate to ad set level
Set audience, placements, budget, schedule normally. Frequency cap lives in Optimization & Delivery section near the bottom.
Step 3: Set frequency cap (X impressions per Y days)
Default is 1 impression per 7 days. Common configurations:
- Awareness, large audience: 1/7 days
- Awareness, smaller audience: 2/7 days
- Reach with brand reinforcement: 3/7 days
- Retargeting via Reach: 5/7 days
Step 4: Save and monitor
Run for 72 hours minimum. Add Frequency column to your view. Check observed frequency tracks below your cap.
Frequency Cap Benchmarks by Campaign Type
| Campaign Type | Recommended Cap | Target Frequency | Watch For |
|---|---|---|---|
| Awareness | 1-2 / 7 days | 1.2-1.8 | Ad recall lift |
| Consideration | 2-3 / 7 days | 1.8-2.5 | CTR drop, video view rate |
| Retargeting (warm) | 3-5 / 7 days | 2.5-4.0 | Negative feedback rate |
| Cold prospecting | 1-2 / 7 days | 1.0-1.5 | CPM stability, hook rate |
| Cart abandoners | 5-7 / 7 days | 3.5-5.5 | CVR, hide-ad rate |
Retargeting tolerates higher frequency because intent is established. Cold prospecting needs tightest cap because audience perception is being formed.
How to Identify Ad Fatigue (Without Frequency Caps)
Most 2026 campaigns won't have frequency cap option. Monitor manually with these signals:
- CTR drops 20%+ from 7-day rolling average — earliest fatigue signal
- CPM rises noticeably while audience/placements unchanged — relevance score declining
- Frequency above 4 on conversion campaign = yellow flag; above 6 = red flag
- Negative feedback rises — hides, "I don't want to see this", reports
Cleanest fix: creative rotation. Refresh top-spending creative every 14-21 days for cold campaigns, 7-10 days for retargeting. See our 2026 algorithm changes guide.
Frequency Cap vs Frequency Threshold (the new 2026 setting)
Q1 2026, Meta introduced Frequency Threshold in Advantage+ Shopping. Not the same as frequency cap.
Frequency cap: hard ceiling. "Never show more than X times in Y days." Strictly enforced.
Frequency threshold: soft suggestion to Andromeda. "Try to keep average frequency near this number, but exceed it if conversion probability is high." Input to optimization, not a delivery rule.
Common Mistakes to Avoid
- Setting cap on conversion campaign assuming it works — field doesn't exist in 2026
- Capping too tightly on small audiences — causes severe under-delivery
- Ignoring placement-level frequency — Feed + Reels + Stories = frequency 3, not 1
- Confusing cap with reach goal — they work together but aren't interchangeable
- Not refreshing creative — cap of 2 doesn't help if all ads use same hook
- Forgetting engaged-view attribution — reported conversions may include views, masking fatigue
How 1ClickReport Tracks Ad Frequency Across Campaigns
1ClickReport connects directly to your Meta Ads account and surfaces frequency, CTR, CPM, quality ranking across every active campaign in one view. Ask in plain English: "Which of my Meta campaigns have frequency above 3 with declining CTR this week?"
Solo plan auto-flags ad sets breaching common fatigue thresholds. Premium lets you pause or rotate creative directly from chat. Either way, you catch fatigue the day it starts — not in last week's report.
FAQ
What's the ideal Facebook frequency cap?
Awareness: 1-2/7d. Consideration: 2-3/7d. Retargeting warm: 3-5/7d. Conversion campaigns don't allow manual caps — Meta optimizes automatically.
Why can't I find frequency cap in my campaign?
Only appears in Reach (and legacy awareness) campaigns. If you chose Sales, Leads, Traffic, Engagement, or Advantage+ Shopping, the option is hidden because Meta's algorithm controls cadence.
Does frequency cap work across Facebook and Instagram?
Yes. Enforced at user level across all placements. One user seeing your ad once on IG Feed and once on FB Reels = frequency 2.
What's a healthy frequency number?
Prospecting: 1.0-1.8 weekly. Retargeting: 2.5-4.0 weekly. Sustained frequency above 5 = fatigue signal, requires creative refresh.
Can I set frequency cap on Advantage+ Shopping?
No hard cap. As of Q1 2026 you can set frequency threshold (soft suggestion). Meta's Andromeda model has final say.
