Facebook ads not spending: every cause and a 2-minute check

The 2-minute check

Work from the top down. Each step either finds the cause or rules it out.

1. Read the Delivery column at every level. Open the campaign, the ad set and the ad, and hover over any warning or error status — Meta adds an explanation and the fix there.
2. Check payment and limits. In Billing & payments: a failed payment, the ad account spending limit, a campaign spending limit or Meta’s daily spending limit.
3. Check review. Is the ad still In review, Rejected or Preparing? A brand-new ad may simply need more time.
4. Check budget and schedule. Start and end dates, delivery hours, and whether the budget is large enough for the result you optimise for.
5. Check bid, audience and learning. A bid cap or cost per result goal set too low, an audience that is too narrow, or an ad set stuck in Learning limited.

We recommend checking the status of your ad at all levels if you are experiencing delivery issues.

What each Delivery status means

These are the statuses Meta lists for Ads Manager, with what to do about each:

Not delivering isn’t in Meta’s current status list. Meta’s help page says it will appear if the ad, ad set or ad campaign has been turned off or has finished its scheduled course of delivery — and that it is different from a rejection.

Payment and spending limits

Money problems stop everything at once, so check them first. Meta’s comparison page puts it plainly: only budgets, spending limits and available funds pause ads.

• Failed payment. your ads are paused and your ad account is disabled until you pay the amount due (source). Billing & payments may show the account as unsettled.
• Campaign spending limit. Once reached, every ad set and ad in the campaign stops (source).
• Meta’s daily spending limit. Meta sets one for most advertisers; when you reach it, ads pause and resume after midnight in the ad account’s time zone.
• Payment threshold. Not a cause: Your ads continue running after you reach your payment threshold.
• Restricted account or Page. A restricted ad account has its ads disabled, and a restricted Page isn’t allowed to advertise (source).

Ads in review or rejected

New and edited ads go through review first. Most ads are reviewed within 24 hours, although in some cases it may take longer. (source)

Even after review, Meta says you may need to wait up to 24 hours to see delivery. If an ad has been published for at least 48 hours and nothing else fixes it, Meta recommends deleting and recreating it.

If the ad was rejected, fix what the rejection names or request another review; Meta aims to decide within 48 hours. Update required is different: the Page running the ad was unpublished, or a post or product it uses is gone. Fix that and switch the ad set back on yourself — it doesn’t restart on its own.

Budget, bids and schedule

An ad set can be fully approved and paid for and still not spend, because its settings leave the auction nothing to work with:

• Budget too small for the result. Meta’s rule of thumb: a daily budget at least 10 times the average cost of your optimisation event. With a cost per result goal, at least 5 times that goal (source).
• Bid cap or cost per result goal too low. A low bid can limit or prevent delivery. (source) To test, Meta suggests removing the cap and seeing whether delivery starts.
• Campaign budget spread unevenly. With Advantage+ campaign budget, Meta may not spend the budget equally on each ad set, so one ad set can get almost nothing.
• Schedule. A start date in the future shows Scheduled; a passed end date shows Completed. Delivery hours work with a lifetime or daily budget — but very short hours leave little time to spend.
• Late or frequent changes. Raising the budget late in the day leaves only a few hours to spend it, and frequent pauses interfere with pacing (source).

Audience size and learning

An ad set leaves the learning phase after about 50 results in the week after its last significant edit. If that looks unlikely, Meta marks it Learning limited:

An ad set becomes learning limited when it is unlikely to receive about 50 optimization events in the week after your last significant edit.

Meta lists the usual reasons: small audience size, low budget, low bid or cost control, high auction overlap, an infrequent optimization event. It also says learning limited isn’t a penalty — the ad set still delivers, just less steadily.

Edits that restart learning include any change to targeting, creative or the optimisation event, adding a new ad, changing the bid strategy, and pausing the ad set for 7 days or longer (source). Making them every day keeps an ad set learning for good.

Spending, but less than the budget

A daily budget is an average over the week, not a fixed amount per day. Meta’s daily budget page: on some days spending can reach 175% of the daily budget, on others less, and over a week it won’t go above 7 times the daily budget.

So one slow day is normal. A week well below budget usually comes from the same causes as above in a milder form: a narrow audience, a low bid or cost goal, or a campaign budget that favours other ad sets.

When the conversion event is the problem

If you optimise for purchases or leads, delivery depends on Meta seeing those events. Meta warns you when it predicts zero conversions for an ad set, and suggests choosing an event that happens at least about 50 times a week.

A sudden drop in pixel events — broken pixel code, a site that was down, a wrong domain allow list — has the same effect. Meta’s troubleshooting page recommends checking with the Test Events tool in Events Manager.

Run the check with an AI assistant

Everything above is readable through Meta’s Marketing API, so an assistant connected to your ad account can do the check in one question: “Why is my ad set not spending?” It reads:

• the ad account’s account_status — 1 is active, 2 disabled, 3 unsettled, 9 in a grace period after a failed payment — and its spend_cap, where Meta’s reference says When the amount is reached, all delivery stops. (source);
• each campaign’s, ad set’s and ad’s effective_status and issues_info, the issues that prevented delivery;
• the ad set’s learning_stage_info, where FAIL means it isn’t getting enough results to exit learning (source).

Meta’s own ads MCP server has a tool for exactly this — ads_get_errors, which Return delivery-blocking errors for campaigns, ad sets, ads, or an ad account. (source) Setup is in our guides for ChatGPT and Claude.

How Variafy catches it before you look

The checks above work when you already suspect a problem. Variafy runs them on its own: every 15 minutes its watchdog looks at each connected ad account and emails you when:

• nothing was spent yesterday and nothing is running today, though campaigns are active;
• a campaign is active with a daily budget but spent nothing yesterday while the rest of the account did;
• the ad account reached its spending limit, a payment failed, or the account is disabled or unsettled;
• ads were rejected, or an ad set can’t deliver at all;
• conversion tracking stopped sending events.
