You’ve launched your campaign, uploaded polished creatives, set a budget, and hit “Publish.” Then you check back a few hours later — zero impressions. No spend. No reach.
If this sounds familiar, you’re dealing with one of the most frustrating issues advertisers face: Facebook ads not delivering.

In Meta’s advertising ecosystem, “not delivering” doesn’t always mean something is broken. It means your ads aren’t entering the auction system — the place where impressions are won or lost. Understanding why this happens and how to fix it is crucial to keeping your campaigns performing consistently.

In this guide, we’ll break down the technical meaning of “not delivering,” explore 12 real-world reasons behind it, and share practical fixes used by experienced advertisers. Whether you manage multiple accounts or optimize campaigns daily, this walkthrough will help you restore delivery and prevent downtime.

What 'Not Delivering' Technically Means in Meta Ads

"Not Delivering" is not a performance problem; it's a gatekeeping problem. This is a specific technical state where your campaign, ad set, or ad has an "Active" status but shows zero impressions and $0.00 spend long after it should have started.

It's crucial to understand that this is not the same as:

• Poor Performance: (High CPA, low CTR)

• Learning Limited: (Getting some impressions, but not enough to optimize)

• Under-delivery: (Spending some budget, but less than the daily cap)

"Not Delivering" means your ad is systematically failing to even enter the auction system. The algorithm is, for a reason we will diagnose, disqualifying your ad before it ever gets a chance to compete.

How to Confirm the Facebook ad not delivering status

Before you touch a single setting, your first step is a 10-second diagnosis.

1. Navigate to your Ads Manager and view the Ad Set level.

2. Find the "Delivery" column for the ad set in question.

3. Hover your mouse directly over the status (e.g., "Active," "Error").

The tooltip that appears is Meta's own diagnostic. It is the single most important piece of information you have. It will often provide a specific reason, such as "Error: Bid too low," "Not delivering," or "Audience too small."

Why Facebook Ads Are Not Delivering

Once you understand the mechanics, it’s time to dig into the real causes. Most “not delivering” issues stem from approval delays, targeting overlap, bidding limitations, or account-level restrictions.

Let’s explore each in detail and how to fix them effectively.

1. Ad Rejection or Pending Review

Meta reviews every ad to ensure it complies with the Meta Advertising Standards. While most reviews finish within 24 hours, delays happen, especially during high-volume ad periods.

If your ad shows “In Review,” it won’t deliver until approved. A disapproved ad, on the other hand, will stay inactive until you edit and resubmit it.

How to fix:

• Double-check your ad content for policy violations (restricted keywords, sensitive categories, etc.).
  

• If you believe your ad complies with the policy, use the Request Review button within Ads Manager.
  

• For repeated rejections or compliance concerns, review your Facebook Ads Account Quality dashboard.

2. Audience Overlap and Competition Within Ad Sets

Meta’s system can’t decide which ad to prioritize when two or more ad sets target similar audiences. This internal competition often results in one ad set winning auctions while others barely deliver.

How to fix:

• Use Meta’s Audience Overlap tool to check duplication percentages.

• Combine overlapping ad sets or refine targeting to minimize overlap.

• Consider running Advantage+ Audience to let Meta optimize across audiences automatically.

If your campaigns consistently struggle with delivery despite good structure, check whether your overall account setup has too many competing ad sets, something we discussed in depth in Facebook Ads Account Error.

3. Narrow Targeting or Low Audience Size

While precision targeting seems smart, going too narrow can stop your ads from delivering entirely. Meta requires a minimum audience size for the auction to function efficiently.

For example, a retargeting audience with only a few hundred people may never generate impressions if competition is high.

Recommended audience sizes:

• Awareness campaigns: at least 500k+ users.

• Conversion campaigns: 50k–200k users per ad set.

Solutions:

• Broaden targeting slightly (e.g., widen age range, add interests).

• Use Advantage+ Audience or broad targeting with conversion optimization.

• Merge ad sets with similar targeting to increase reach and data density.

4. Low Bid or Budget Below Auction Threshold

Meta’s ad delivery depends on winning the auction. If your bid or daily budget is too low, your ad may never enter bidding rounds.

Campaigns with a $1 daily budget or extremely low cost caps typically underdeliver or stall completely.

How to fix:

• Increase your bid strategy — especially if using “Cost Cap” or “Bid Cap.”

• Raise your daily budget to ensure enough auction participation.

• Allow Meta’s pacing algorithm to stabilize before making further changes.

5. Schedule and Start Date Issues

Sometimes, the problem isn’t algorithmic — it’s a simple scheduling mistake.
Ads set for future start dates, incorrect time zones, or misaligned scheduling between ad sets and campaigns can all cause zero delivery.

Quick checks:

• Verify that your campaign start date has passed.

• Make sure your account’s time zone matches your intended ad schedule.

• Avoid frequent pausing and reactivation, which resets pacing.

6. Learning Phase and Algorithmic Freezing

When you publish a new ad set, Meta’s system needs to collect data before it can optimize delivery, this is called the learning phase. If you make too many changes too quickly, the algorithm struggles to stabilize, and delivery can freeze.

Key distinctions:

• Learning Phase: Gathering data; delivery active but unstable.

• Learning Limited: Too few conversions to complete learning.

Fixes:

• Consolidate ad sets to accelerate learning.

• Avoid changing budgets or creatives during the learning phase.

• Use Campaign Budget Optimization (CBO) for steadier delivery.

7. Too Many Ad Set Edits

Frequent edits — changing creatives, budgets, or targeting — reset the learning process. When this happens repeatedly, Meta temporarily pauses delivery until it recalibrates.

Best practice:

• Wait at least 24–48 hours between significant edits.

• Batch all adjustments together (budget + creative) to minimize resets.

• Use “duplicate and modify” instead of editing live ads when testing.

8. Account Spending Limit or Payment Issues

Even if your ad looks perfect, it won’t run if your account spending limit has been reached or your payment method fails. Meta stops delivery automatically in these cases.

How to fix:

• Go to Billing > Payment Settings and review your spending limit.

• Increase or remove the limit.

• Ensure your payment method is active — expired cards or failed charges halt delivery.

If payment setup issues persist, check our detailed guide on Add Payment Method for Facebook Ads and Facebook Ad Account Spending Limit for safe setup practices.

9. Restricted or Disabled Account / Ad Access

Policy violations, unauthorized activity, or repeated disapprovals can lead Meta to restrict or disable ad accounts. When that happens, all ads stop delivering immediately.

What to do:

• Visit the Account Quality dashboard.

• Review alerts, flagged assets, or Business Manager restrictions.

• File an appeal if the issue was caused by a false positive.

In some cases, you may need to verify your account identity or business details. Our guide on Verify Facebook Ad Account explains this process in detail.

10. Ad Fatigue or Low Relevance Score

If your ad receives poor engagement, Meta’s algorithm deprioritizes it in auctions. Low CTR, negative feedback, or outdated creatives reduce your quality ranking and thus delivery frequency.

How to fix:

• Refresh ad creatives every 7–14 days.

• Review performance metrics: CTR, Quality Ranking, Engagement Rate Ranking.

• Use dynamic creatives or carousel formats to re-engage audiences.

11. Targeting Conflicts in Advantage+ Campaigns

Advantage+ automations are powerful but can conflict with manual settings — especially if you mix automated placements with specific audience exclusions. When the algorithm can’t reconcile the instructions, delivery halts.

Fixes:

• Simplify structure: avoid redundant layers of targeting.

• Stick with either fully automated or fully manual settings per campaign.

• Reset optimization events if they conflict with conversion goals.

12. Conversion Event or Pixel Tracking Errors

Conversion-based campaigns rely on the Facebook pixel or API events to track performance. If the pixel isn’t firing correctly or the chosen conversion event is inactive, your ads may stop delivering entirely.

Steps to fix:

• Open Events Manager to verify pixel activity.

• Use Meta Pixel Helper to test firing accuracy.

• Re-map your conversion event to an active one (e.g., “Add to Cart” or “Purchase”).

Incorrect or inactive events are among the top technical reasons ads stop delivering — and one of the easiest to fix once identified.

How to Systematically Fix Facebook Ads That Aren’t Delivering

Don't just randomly change settings; you'll reset the learning phase and make things worse. Follow this diagnostic checklist.

Step 1. Diagnose the Root Cause in Ads Manager

1. Check Account-Level Status: Go to Account Quality. Are there any red flags? If yes, this is your problem. Stop here and resolve the Facebook Ads Account Restriction first.

2. Check Billing: Go to the Billing tab. Is your payment method active? Have you hit your Facebook ad account spending limit? If yes, fix this.

3. Check the Delivery Column (Ad Set Level):

• What does the "Delivery" column say?

• Hover your mouse over the status. Read the tooltip. This is Meta's own diagnosis. It will often tell you exactly what's wrong (e.g., "Error: Audience too small," "Error: Bid is too low").

Step 2. Apply Corrective Actions by Category

Based on your diagnosis in Step 1, take one of these targeted actions. Do not do all of them.

• If it's a Policy Issue (Account Quality):

• Stop. Read the violation notice.

• If it's an ad, edit it for compliance or request a review.

• If it's your account, you will need to appeal.

• If it's a Billing Issue:

• Add a new payment method or reset your account spending limit.

• Wait 1-2 hours for the system to re-authenticate.

• If it's an Auction/Audience Issue ("Active" but 0 impressions):

• Duplicate the Ad Set: This is the fastest "hard reset." Create an exact duplicate of the non-delivering ad set. Sometimes this is all it takes to get it "picked up" by the auction system.

• Widen the Audience: Remove one or two targeting restrictions.

• Increase the Budget: Double the daily budget for 24 hours.

• Change Bid Strategy: If you're on "Bid Cap," switch to "Highest Volume."

• If it's a Technical (Pixel) Issue:

• Pause the campaign.

• Go to Events Manager and use the "Test Events" tool to confirm your optimization event is firing correctly.

• Do not resume the campaign until you see the event firing in the "Test Events" tab.

Step 3. Use Meta’s Automated Tools for Optimization

If you're still stuck, it's time to stop fighting the algorithm and start working with it.

• Consolidate: Instead of 10 ad sets with $10/day, try one CBO (Campaign Budget Optimization) campaign with 5 ad sets and a $100/day budget. This forces more data through fewer ad sets and helps exit the learning phase.

• Trust Advantage+: Create a new Advantage+ campaign. Give it your best-performing audience as a "suggestion" and let Meta's AI find the customers.

Step 4. Monitor Post-Fix Performance

After applying a fix (especially duplicating an ad set or changing the budget), you must wait. The algorithm needs 24-72 hours to recalibrate. If you keep "tinkering," you will be stuck in a permanent loop of non-delivery and learning resets.

Pro Tips to Prevent Future Delivery Problems

Fixing is good. Prevention is better. Integrate these habits into your workflow.

• Build Testing Campaigns: Instead of constantly editing your main "control" ad set, create a separate CBO campaign for testing new creatives or audiences. Drag and drop winning ads into your main campaign once they're proven.

• Warm-Up New Accounts: If you're working with a new ad account, don't start with a $1,000/day conversion campaign. This is a massive red flag. Warm it up for 3-5 days with a simple Traffic or Engagement campaign at a low budget ($20-$50/day).

• Maintain Consistent Activity: Don't let an ad account go "dark" for months. Inactive accounts are more likely to be flagged for review or have issues with delivery when they're suddenly reactivated with a high budget.

• Use A/B Testing: Use Meta's built-in A/B testing tool to scientifically test variables (like audience or creative). This avoids the manual "ad set reset" problem and gives you clean data.

When to Contact Meta Support

As an experienced advertiser, you know Meta Support can be a mixed bag. However, there are times when it's necessary.

Contact support only after you have done all of the following:

1. Checked Account Quality (no issues).

2. Checked Billing (no issues).

3. Confirmed your Pixel/CAPI is firing correctly.

4. Ensured your audience is broad (>1M) and your budget is reasonable.

5. Waited 72 hours with the ad "Active" and seen zero impressions.

If you meet all those criteria, you likely have a technical freeze or a "stuck" ad that only a manual, internal push from Meta can fix.

How to Prepare:

• Go to the Meta Business Help Center.

• Have your Ad Account ID ready.

• Have the specific Ad Set ID (and Ad ID) ready.

• Take screenshots of your "Active" status, $0 spend, and your (working) Events Manager.

• Clearly state: "My ad set [ID] has been Active for 72 hours with 0 impressions. I have confirmed my billing, pixel, and policy status are all healthy. Please escalate this to the technical team for a manual review."

FAQs

Why is my "Active" ad not delivering?

"Active" only means your ad has been approved and is scheduled to run. It does not mean it is winning auctions. The most common reasons are that your budget or bid is too low to compete, your audience is too narrow, or your ad is stuck in a processing loop.

How long does it take for a new Facebook ad to start delivering?

Typically, an ad will start delivering within a few hours of being approved. However, it can take up to 24 hours for the system to fully ramp up and for delivery to become stable. If you have zero impressions after 24 hours, start this diagnostic guide.

Will increasing my budget fix non-delivery?

It will fix non-delivery if the root cause is a budget that is too low to enter the auction. It will do nothing if the cause is a restricted account, a broken pixel, or a future start date.

My ad set says "Learning Limited." Is that why it stopped delivering?

"Learning Limited" means it is delivering, just sub-optimally. However, if an ad set remains "Learning Limited" for a long time, the algorithm may heavily deprioritize it, causing delivery to drop significantly. The fix is to provide more budget or consolidate ad sets to push at least 50 optimization events per week.

Why do new ad accounts have so many non-delivery problems?

Meta's systems treat new accounts as high-risk to prevent fraud and spam. Your account has no "trust history." This leads to:

• Stricter Reviews: Your ads will stay "In Review" longer.

• Low Default Spending Limits: You will have a low, automated Facebook ad account spending limit imposed until you've proven you're a legitimate advertiser.

• Algorithmic "Cold Start": The algorithm has no pixel data or performance history to learn from. This makes initial delivery very slow. This is why "warming up" an account with a low-budget Traffic or Engagement campaign for a few days is a best practice.

Why is duplicating an ad set often a successful fix for non-delivery?

This action acts as a "hard reset" for the algorithm. When you duplicate an ad set, you are forcing Meta to register a brand-new auction entry with a new ID. This can effectively bypass a "stuck" ad set that might be frozen in a processing loop or a glitched algorithmic state. It doesn't fix the original ad set's root problem, but it gets around it. This should only be used after you've confirmed there are no obvious billing, policy, or technical errors.
