Facebook "Limited Ad Delivery" warning

Quick Answer

Limited delivery usually means your ad's quality ranking is in the bottom third of its auction. Refresh the creative, expand the audience, and check that your landing page loads fast and matches the ad. Within 48 hours of those fixes, delivery should normalise.

Step-by-step fix

1. Open Ads Manager → find the ad with the limited delivery warning → hover over the warning icon to read the specific reason.
2. Check the Quality, Engagement, and Conversion rankings in the ad's columns view. If any are "Below Average" or "Bottom 35%", that's your bottleneck.
3. For low Quality Ranking: replace the creative entirely. Quality is mostly about hide rates and "see fewer like this" reports. New creative resets the score.
4. For low Engagement Ranking: rewrite the headline and primary text to match the audience's pain point more directly. Engagement is about CTR and post-view interactions.
5. For low Conversion Ranking: improve the landing page (faster load, clearer CTA, better mobile experience). Conversion ranking compares your post-click rate to others in the auction.
6. Expand the audience by 2-3x. Narrow audiences hit delivery walls faster.
7. Increase the budget by 20-50% so the algorithm has more room to find buyers. Counterintuitively, higher budgets often release limited delivery.
8. Wait 48 hours for the delivery system to recalculate. Don't keep tweaking — that resets the learning phase and makes things worse.

Why it happens

"Limited delivery" appears when Meta's auction system decides your ad can't compete. There are five common causes:

1. Bottom-third quality ranking. Your ad is being hidden, reported, or scrolled past more often than competitors in the same auction.
2. Audience fatigue. Frequency above 4-5 in your audience means most people have already seen the ad multiple times, so the algorithm slows delivery.
3. Bid too low. Your max bid is below the auction floor for your audience.
4. Budget too small. Daily budget below 30x your CPA target gives the algorithm too little room.
5. Restricted category not declared. If your ad is borderline-regulated (alcohol, dating, gambling, cosmetic surgery) and you haven't enabled the relevant Special Ad Category or age gate, delivery is throttled while the system decides.

Additionally, in 2024 Meta introduced "low signal delivery" — when your conversion event is firing too rarely (less than 50/week per ad set), the algorithm can't optimise and throttles the campaign.

How to prevent it

• Refresh creative every 2-3 weeks to keep quality scores high.
• Maintain a healthy audience size: at least 500,000 for prospecting, at least 50,000 for retargeting.
• Set daily budgets that allow for at least 50 conversions per week at your target CPA.
• Use value-based bidding (bid cap or cost cap) only after you have at least 50 conversions per week of historical data.
• Monitor frequency in the columns view. Pause and refresh ad sets above frequency 4.
• Send server-side conversion events via the Conversions API to give the algorithm cleaner signal.
• Check landing page speed in PageSpeed Insights — anything over 3 seconds on mobile hurts conversion ranking.

When to escalate to Meta support

Limited delivery is almost never a support issue — it's an algorithmic feedback loop you fix yourself. Escalate only if:

• The warning persists for more than 7 days after creative refresh and budget changes.
• You're seeing limited delivery on multiple campaigns simultaneously, across different audiences (suggests an account-wide issue).
• The warning has no specific reason listed (Meta's UI shows a blank tooltip).

Use the Pro Team Chat in Ads Manager. Mention the campaign IDs and what you've already tried. Account-level delivery issues sometimes need a Meta engineer to manually release a soft restriction.

Pix-Vu mention

The fastest way to refresh a fatigued ad and improve quality ranking is to upgrade the creative without re-shooting. Pix-Vu lets you upscale, denoise, and modernise your existing ad images so they look fresh to the algorithm and to users — often releasing limited delivery within 24 hours.
