Note
Updated May 2026. Live operator diagnostic. If your Meta ad is active, budget is set, audience is defined, and impressions are zero or near-zero - this is the order to check. The most common 2026 cause is the Andromeda rollout interacting with audience size estimates and Learning Phase, but there are 9 other causes worth ruling out first because most are 2-minute fixes.
If you Googled "Meta ads not delivering" because Ads Manager shows your ad is Active but you have zero impressions, zero spend, or under-delivery vs your daily budget - read the diagnostic order below before changing anything. The single most expensive mistake is panicking and editing the ad set, which usually triggers a Learning Phase reset on top of whatever the actual issue was.
This guide covers the 10 causes ranked by likelihood, the 5-minute diagnostic order, and the fix for each.
First: confirm 'not delivering' vs 'under-delivering'
These are two different problems with different causes:
| Symptom | Meaning | Most likely cause |
|---|---|---|
| Zero impressions, zero spend, status Active | Truly not delivering | Ad rejected, audience size 0, daily budget too low to enter auction, billing issue |
| Some impressions, well below daily budget cap | Under-delivering | Audience too narrow, bid too low, frequency cap, attribution settings, Andromeda exploration |
| Impressions but no conversions | Delivering, attribution problem | Pixel/CAPI not tracking - different problem, see linked guide |
If you have impressions but no conversions, that's a tracking issue, not a delivery issue. Jump to /blog/meta-pixel-not-tracking-conversions. The rest of this guide assumes truly not delivering or significantly under-delivering.
10 causes of Meta ads not delivering
Ranked roughly by likelihood in 2026.
Cause 1: Ad rejected (silent or with notice)
What it is. Your ad was rejected in review but Ads Manager still shows status "Active" because you haven't refreshed. Rejected ads do not deliver.
Signal. Open the ad - if rejected, there's a red banner or "Rejected" status in the Quality column. Sometimes the rejection is silent and only shows on Inspect.
Fix. Appeal via the rejection notice. Don't edit the ad before appealing - editing often confirms the rejection. If 5+ ads on the same account get rejected in 24 hours, file a Business Help Center ticket; account-level review may be needed.
Cause 2: Daily budget too low to enter the auction
What it is. Meta's auction needs a minimum daily budget to clear, which scales with your CPM. In high-CPM verticals (B2B, finance, legal), a 5-10 USD daily budget cannot win any impressions.
Signal. Daily budget below 50 USD on a campaign in a niche where average CPM is over 25 USD. Audience size estimate looks fine.
Fix. Raise daily budget to a minimum of 2x the typical CPM for your vertical. For high-CPM B2B, that often means 50-100 USD/day per ad set as a floor.
Cause 3: Audience size too small or shows 0
What it is. Audience configuration produces a size of zero or below the minimum threshold (typically ~1,000 active users). Common cause: stacked exclusions, conflicting interests, geographic restriction.
Signal. Open ad set > Audience. Estimated audience size shows 0, less than 1K, or "narrow."
Fix. Remove the most restrictive exclusion. Broaden geographic targeting. Remove interest stacks that have AND logic creating impossible intersections.
Cause 4: Account-level billing or payment issue
What it is. Failed payment, expired card, hit spending limit, account restriction. Meta freezes delivery without cancelling the campaign.
Signal. Account-level notification banner. "Payment failed" email. Spending Limit reached message in Billing.
Fix. Open Business Settings > Billing & Payments. Resolve the payment issue. Delivery typically resumes within hours of payment clearing, sometimes immediately.
Cause 5: Ad set scheduled outside delivery window
What it is. Schedule shows the ad set is outside its delivery window (start date in future, end date passed, daypart restrictions excluding current hour).
Signal. Schedule tab shows current time outside the active window. Status may say "Not delivering - off schedule."
Fix. Update schedule. If running daypart restrictions, verify the timezone - a common bug is setting the schedule in your timezone but Meta interpreting it in account timezone.
Cause 6: Bid cap or ROAS goal too restrictive
What it is. You set a bid cap below market clearing price, or a target ROAS that no impression can clear at current auction prices.
Signal. Manual bid cap set; ad set winning zero impressions. Target ROAS set 30%+ above account historical average; delivery low.
Fix. Remove or raise the bid cap by 25-50%. Drop target ROAS to within 10% of account historical average. Run for 7 days before re-tightening.
Cause 7: Learning Phase reset trapping the ad set
What it is. Recent edits triggered Learning Phase resets repeatedly. Each reset cuts delivery while the algorithm re-explores. After 2-3 resets, delivery never recovers.
Signal. Ad set history shows 2+ Learning resets in 30 days. Delivery declines step-wise after each edit.
Fix. Stop editing. Freeze the ad set for 14 days. If delivery doesn't recover, duplicate the ad set fresh - the duplicate gets a clean Learning window. Full guide at /blog/meta-ads-learning-phase-stuck.
Cause 8: Andromeda audience signal re-evaluation (May 2026 specific)
What it is. During the Andromeda rollout, audience signal re-evaluation produces temporary delivery dips on accounts mid-rollout. Audience size estimates fluctuate; ad sets that were delivering yesterday under-deliver today.
Signal. Started in March-April 2026. Audience size estimate showing variance day-over-day. No account-side change explains the dip.
Fix. Hold steady through the 4-6 week per-account stabilization window. Verify Conversion API is running. Full diagnostic at /blog/meta-andromeda-issues-may-2026.
Cause 9: Frequency cap suppressing delivery
What it is. Tight frequency cap limits how often any individual user sees your ad. Combined with a small audience, frequency cap can effectively cap total impressions below your budget.
Signal. Frequency cap is set explicitly. Audience size estimate is small (under 500K). Average frequency in reporting is at the cap.
Fix. Remove the frequency cap or raise it. Audiences below 500K rarely benefit from frequency caps - the natural exposure rate is below the cap anyway.
Cause 10: Ad credits depleted on a credit-funded account
What it is. Account is funded by ad credits (promotional, agency, or grant) and credits ran out. Delivery stops until additional funding is added.
Signal. Billing tab shows credit balance at 0. No active payment method as fallback.
Fix. Add a backup payment method or top up credits. Some accounts require manual review by Meta to switch from credit to card billing.

Pros
- Step 1: Open the ad. Check Quality column for Rejected status. (30 sec)
- Step 2: Open Billing. Check for payment failures or spending limit hits. (30 sec)
- Step 3: Open ad set > Audience. Verify audience size estimate is non-zero. (30 sec)
- Step 4: Check schedule, timezone, and current delivery window. (30 sec)
- Step 5: Check daily budget vs vertical CPM. Below 2x CPM is a problem. (30 sec)
- Step 6: Check bid cap and target ROAS settings. (1 min)
- Step 7: Check ad set edit history for recent Learning resets. (1 min)
- Step 8: If all 7 above are clean, suspect Andromeda; verify CAPI and hold steady (1 min)
Cons
- The diagnostic is 5 minutes; the fix can take 24-72 hours for delivery to fully recover
What NOT to do when ads stop delivering
The 'do not panic' rules for delivery
When this fits
Recommended: Run the 8-step diagnostic before making any changes. Verify rejection status before assuming Meta is broken. Check billing before assuming account is fine. Hold edits until you've identified the cause. Document the date and time the issue started. Use Duplicate-to-test rather than editing the original ad set if you want to test a fix. Wait 24 hours after a fix before further intervention.
When to skip
Recommended: Editing the ad set 5 times in an hour trying to make it deliver. Pausing and reactivating the campaign repeatedly. Cranking the budget up while the underlying issue is unresolved. Filing a Meta support ticket without first checking billing and rejection status. Assuming 'not delivering' is the same as 'not converting' (different problem). Cutting budgets on healthy ad sets because one delivery issue panicked you into account-wide changes.

How Hyper helps
When delivery stops, the cause is usually one of the 10 above and the fix is usually fast - but only if you spot the issue in time. Hyper agents monitor delivery health continuously and flag anomalies (zero impressions for 2+ hours, spend below 30% of pace, audience size anomalies, billing issues) within minutes rather than waiting for a daily review. The agent surfaces which of the 10 causes is the likely culprit so you skip straight to the fix instead of running the full diagnostic. Case study: /blog/ai-marketing-case-study.
Across 1,000+ customer accounts and 10M+ USD/month managed ad spend, the most common delivery interruption flagged is billing-related (45% of incidents in our 2025 telemetry), followed by ad rejections (22%), audience configuration (15%), and budget-too-low (10%) - the same ranked likelihood reflected in this post's diagnostic order.

Frequently asked questions
Q: Why is my Meta ad not delivering despite being Active?
Most common causes in order: (1) ad rejected in review but Ads Manager hasn't refreshed the status, (2) billing issue or spending limit reached, (3) audience configuration producing zero or near-zero size, (4) daily budget too low to enter auction in your vertical's CPM range. Run the 8-step diagnostic above to identify which one before making changes.
Q: How long should I wait before assuming an ad isn't delivering?
For new ad sets, give Meta 4-8 hours to ramp delivery before assuming there's a problem. For previously-delivering ad sets that suddenly stopped, the issue is usually evident within 1-2 hours. Beyond 24 hours of zero spend on an Active ad, the cause is almost always one of the 10 listed in this post.
Q: Will editing the ad set help if it's not delivering?
Usually no, and often it makes things worse. Edits trigger Learning Phase resets that compound the delivery problem. Identify the actual cause (rejection, billing, audience, budget) before editing. The fix is usually at the cause level, not at the ad set level.
Q: Can the Andromeda rollout cause Meta ads not to deliver?
Yes - during the per-account rollout window (typically 4-6 weeks), audience signal re-evaluation can produce temporary delivery dips. Combine that with Learning Phase resets on edits and some accounts see weeks of under-delivery. The fix is verify Conversion API, hold steady, and wait through the stabilization window. Full diagnostic at /blog/meta-andromeda-issues-may-2026.
Q: My ad has impressions but no conversions - is that the same problem?
No. Impressions but no conversions is a tracking issue (pixel, CAPI, AEM priority, or attribution setting), not a delivery issue. See /blog/meta-pixel-not-tracking-conversions for that diagnostic.
Q: Why does my ad spend pause overnight and resume in the morning?
Most common cause: daypart restrictions in the schedule. Less common: account-level spending limit hit during peak hours then reset at midnight UTC. Check both before assuming Meta is broken.
