Yesterday your ads were bringing in orders. Today the numbers look like someone switched them off. Nothing obvious changed, Meta support has no answer, and the forums are full of people saying the platform is broken.
Before you rebuild campaigns or pause everything, take a breath. A sudden drop always has a cause, and in most cases you can find it in your own account and your own store within an hour. The key is to check things in the right order: first what can stop sales completely, then what changed, then where the change is concentrated.
First: rule out the things that stop sales entirely
These take a few minutes to check and explain a surprising number of “overnight” drops.
- Account and ad status. Are your ads still active and delivering? Look for rejected ads, restricted accounts, payment failures or spending limits that were reached.
- Did the spend actually happen? If spend dropped sharply, the problem is delivery, not performance.
- Website and checkout. Place a test order. Check that the payment methods work, products are in stock, prices are correct and the pages load on mobile. A broken checkout looks exactly like a performance collapse in Ads Manager.
- Store orders vs reported purchases. Compare the orders in your store with the purchases reported in Ads Manager for the same days. If your store still has orders but Ads Manager shows fewer, the drop may be partly in the reporting, not in real sales.
If all of these are fine, the drop is real and it came from a change somewhere. Now you need to find it.
Second: find out what changed
A “sudden” drop almost always comes from one of four places.
A change you made
Edits to budgets, targeting or optimization settings can restart the learning phase and disrupt delivery for several days. New campaigns can start competing with existing ones for the same people. A paused ad can turn out to have been carrying most of your sales. Check the account’s activity history for changes in the days before the drop.
An ad that was carrying the account
In many small accounts, one or two ads produce most of the purchases. If that ad got fatigued, rejected, paused or lost delivery, the whole account drops even though everything else is the same. This is one of the most common causes, and one of the easiest to miss when you only look at account totals.
A change in the market
The end of a sale period, a holiday, the days before payday, a competitor running a big promotion. These shift both the cost of reaching people and their willingness to buy. They affect many advertisers at the same time, which is why forum threads fill up during these periods.
A change in reporting
Meta periodically changes how conversions are attributed and reported. When that happens, the numbers in Ads Manager can move even if your actual sales do not. Your store’s own order data is the reference point here.
Third: find where the drop is concentrated
This is the step that turns a vague feeling into a diagnosis.
Compare two equal periods before and after the drop, for example the 7 days before and the 7 days since. Then look at each level:
- Campaigns. Did all campaigns drop, or mostly one?
- Ad sets. Within the affected campaign, which ad sets lost the most purchases?
- Ads. Within those, which ads lost spend or conversions?
The pattern tells you a lot:
- Drop spread evenly across everything: points to something outside the individual ads, such as the website, the market or reporting.
- Drop concentrated in one campaign or ad: points to that specific element, for example an ad that fatigued, got rejected or lost delivery after an edit.
Then, for the affected area, check which step broke: did impressions get more expensive, did fewer people click, or did fewer visitors buy? That separates auction, creative and website problems. Why Your Meta Ads CPA Is Increasing walks through that split in detail.

What not to do while you investigate
- Do not duplicate or rebuild campaigns immediately. New campaigns start learning from scratch and do not fix a website, reporting or creative problem.
- Do not change several things at once. If you edit budgets, audiences and creatives on the same day, you will not know which change helped or hurt.
- Do not judge by the last 1 or 2 days alone. Purchases are often attributed to a click with some delay, so the most recent days tend to look worse than they will once all conversions are recorded.

Frequently asked questions
Why did my Facebook ads stop working overnight?
The most common causes are an ad that was carrying most of your sales losing delivery, a change you made that restarted learning, a problem on your website or checkout, a market shift like the end of a promotion, or a change in how conversions are reported. Check account status and your checkout first, then compare periods to see where the drop is concentrated.
Should I turn off all my ads when sales drop suddenly?
Usually not. Turning everything off loses the learning your campaigns have built. Find where the drop comes from first. If only one campaign or ad is responsible, act on that one.
How long should I wait before reacting to a drop?
If sales stopped completely, check for breakages immediately. If they dropped but did not stop, look at 3 to 7 days of data before making changes, since recent days are often underreported.
Should I contact Meta support?
If your account is restricted, ads are rejected or billing failed, yes. For performance drops, support rarely has an account-specific answer. Your own data will tell you more.
Can a website change affect my Meta ads?
Yes. A new theme, checkout app, slower pages or tracking changes can reduce both sales and the conversion data Meta uses to optimize. If the drop lines up with a site change, start there.
