It was infuriating as you was never notified when Facebook turned off your ad set or ad randomly. You tried creating a new campaign from scratch, however after some time the same issue occurred. You tried different browsers, even clearing cookies and caches, yet not making any difference.

- I have 30-60€ daily budget per ad set and they are all turning off randomly (only the ad sets). There are no warnings or notifications about this and my ads were already approved.
- When I run an ad on a certain ad account on a particular FB page, the ad is reviewed and approved by FB starts spending money but after a few hours they turn off randomly.
- One of my Ad Sets turned off twice automatically. I contacted support and they said it might be a bug. But when they checked internally, they couldn't see the Ad Set turned off.
This happened to me as well at the ad level on a few of my clients' ad accounts. Facebook turned off the one with great ROAS, twice without any reason at all.
Here are the 3 main reasons why your Facebook ads get turned off automatically:
1. Old "Rules" Set Up Previously
Rules are great assets for automation when you are managing multiple ad accounts concurrently. You or your ex-agency may have set up some hidden rules which instruct Facebook to pause your ad sets or ads upon matching certain criteria, such as ROAS below X, CPA above $X or Spend above $X.
These tend to be overlooked since they aren't visible on your ad account dashboard. You may verify by navigating to your Facebook Ad Account > Rules > Manage rules.


2. Inappropriate Content On Facebook Page
The issue above may happen on just one ad account attached to one specific Facebook page. If your Facebook page tends to leverage on controversial topics and has a track record of getting reported as inappropriate (e.g. post taken down by Facebook), Facebook algorithm will pay extra attention to your ads. It may turn off your ads if your ad receives a lot of negative feedback from Facebook users, before restricting your Facebook Page from advertising.
3. Potential Meta Bugs / Glitches
Back in April 2022, multiple advertisers found that their ads were turned off by Facebook over night. Adding to injury, a number of the ads turned off were some of the best performing assets. While there is no official statement from Meta, it is recommended to check your ad accounts at least 2 times a day (Morning & Before End-of-day) to avoid any bugs from ruining your campaign performance.
