What changed in Meta's terms, and why November 20 matters
Meta updated its Commercial Terms and Self-Serve Ad Terms, the documents everyone accepts without reading when they advertise on Facebook and Instagram. The update adds a new section on AI features.
According to Adweek and other industry outlets, it states that advertisers are solely responsible for whatever Meta's AI features create or change in their ads. The part that got the industry's attention: this covers features Meta turns on by itself, not just the ones you chose. The previous version tied that responsibility to the advertiser deciding to use the tool.
Meta's new terms take effect November 20, 2026
The original date was October 30. On October 23, a Meta spokesperson told Reuters the deadline had moved to November 20.
Industry coverage reads it this way: if you keep advertising after the date, you've accepted the terms. There's nothing to sign and no email to reply to. Keep your campaigns running and you've agreed.
Meta says advertisers can turn off any individual Advantage+ feature in Ads Manager at any time. That's true. The catch is that plenty of advertisers don't realize those features are on in the first place.
This isn't hypothetical: Meta's AI has already changed brands' ads
On October 22, Adweek reported on advertisers pulling ads after Meta's AI had altered them.
- Bookshop.org, the online bookseller, posted on Threads that one of its ads had been "enhanced" ("or ruined, really," in the company's words) by Meta without its knowledge. It has since turned off all of Meta's AI ad features.
- The agency Exverus told Adweek that Meta's AI added sitelinks, translated copy and generated images from brands' photos, sometimes on ads where the feature had never been switched on. Some of those changes made it through several rounds of quality checks and were only caught once the ads were live.
Adweek says Meta didn't answer several specific questions about these cases. Its response was that the generative AI ad terms were folded into the main terms and that each feature can be turned off in Ads Manager.
Why clinics and private practices should pay extra attention
If you work in healthcare, the stakes are higher. Ads for doctors, dentists and clinics usually have to follow professional and regulatory advertising rules. Now imagine an AI generating a new image from your photo, or rewriting your copy to make it more "engaging." A regulator won't care that Meta made the edit: the ad ran under your name. And under the new terms, as far as Meta is concerned, the responsibility is yours too.
The same goes for any business that mentions prices, deadlines or guarantees in its ads. One word swapped by the AI can turn into a promise you never made.
What to review in your account before November 20
The good news: this fits into an afternoon. The bad news: there's no magic button. People who manage Meta ads every day point out that each enhancement has to be checked on its own. Here's the routine:
- Open every active ad in Ads Manager and find the Advantage+ creative enhancements section. Look at what's switched on and turn off anything you don't want, item by item.
- Check your account defaults. Your ad account settings include a creative features area that controls what's switched on by default for new ads. If you skip it, every new ad may start with everything enabled again.
- Preview every placement (Feed, Stories, Reels) before publishing. That's where crops, copy and images you didn't make tend to show up.
- Check again regularly. Some advertisers report settings they had turned off showing up again. This isn't a one-time fix.
- Save screenshots of the ad you approved and of your settings. If something runs differently, you can show what you actually signed off on.
One caveat: menu names in Ads Manager change often. If you can't find a section by that exact name, look for "Advantage+" while editing the ad.
This isn't about treating AI as the enemy. Sometimes testing automatic variations makes sense. The point is that it should be your call, made on purpose, not something the platform switches on while the account stays in your name. If you don't have time to watch this every week, it's worth having someone on your marketing team review your ads one by one.
Frequently asked questions
What changes for Facebook and Instagram advertisers on November 20, 2026?
Meta's updated Commercial Terms take effect, including a new section on AI features. As reported, advertisers become solely responsible for whatever Meta's AI creates or changes in their ads, including features Meta turns on by itself. The original date was October 30 and was pushed to November 20.
Can I stop Meta's AI from changing my ads?
Yes. Meta says each Advantage+ feature can be turned off in Ads Manager at any time. But there's no single switch: you need to check the creative enhancements on each ad, review the defaults in your ad account settings, and keep checking periodically.
Should clinics and private practices worry more about this?
Yes. Healthcare ads usually have to follow professional and regulatory advertising rules. If the AI generates an image or rewrites copy in a way that breaks those rules, the ad still runs under the practice's name, and under the new terms the advertiser is responsible as far as Meta is concerned.
