Advertisers carry the risk of Meta's AI ad edits from November 20

Meta's AI can add text, images and links to live ads, sometimes on ads where nobody turned the feature on. From November 20, 2026, a week before Black Friday, Meta's new ad terms put the risk of those edits on the advertiser.

Meta's AI is already changing live ads

Bookshop.org found an AI illustration in an ad its team had made by hand, after an account update opted it into a generative AI feature, Adweek reported. The agency Exverus told Adweek that Meta's AI has added sitelinks, translated copy and turned a brand's own photos into AI images and carousels, sometimes on ads where nobody switched the feature on. Exverus has had to pull live ads to remove those changes.

These edits come from Advantage+ creative, Meta's AI tools for ads, where each change is called an enhancement. Ryan Adams at Exverus said Meta applies enhancements automatically and that many switches sit in hidden or collapsed menus.

Shoppers don't know Meta's ad policies, so they will likely assume the brand chose to use AI, Emarketer analyst Asa Hiken told Adweek.

Why do advertisers carry that risk from November 20?

Meta's updated Self-serve Ad Terms apply from November 20, 2026. Nobody signs anything. Continuing to use Meta's ad tools counts as accepting them.

Adweek had reported an October 30 start, which is why the post below still shows the old date.

The AI section of the new terms admits these features can get things wrong. The next sentence puts the risk on the advertiser.

"You are solely responsible for and assume any and all risks associated with such AI features and any resulting Ad Creative."

If an agency runs the ads for a store, the terms bind the store as the advertiser, and Meta may also hold the agency responsible if the store breaks them. The same terms make the advertiser responsible for reviewing, approving or removing its ads, even when Meta's automated tools helped generate them.

Under the Ad Creative Generative AI Terms in force since May 2024, advertisers carried the risk only if they chose to use the AI tools. The new wording drops that condition. Meta told Adweek that advertisers can switch off any Advantage+ feature at any time, but did not directly say whether they are liable for features they never turned on.

Until Meta answers that, treat every enhancement running on your ads as one you chose.

Three things to check and switch off before November 20

Agencies quoted by Adweek are not telling clients to stop advertising. David Dweck, president of Go Fish Digital, said the agency won't advise clients to pull back in Q4. So before November 20, go through each live ad in three steps.

  1. Compare what's live with what you uploaded. Open each running ad the way a customer would see it, as @AIBrain suggests, and screenshot the version Meta is actually showing, as @ecombatman suggests. Note every difference.
  2. Turn off anything that can make a promise. @ecombatman says to kill any enhancement that can invent claims such as discounts, guarantees, timelines or results. Do these first, because a shopper will read that promise as yours. Then switch off every Advantage+ toggle you didn't choose, including the ones in collapsed menus, as @AI__Brain advises.
  3. Screenshot your settings when you're done, so you have a record of what you turned on, as @AI__Brain suggests.

Editing a live ad sends it back through review, @ecombatman notes, so do this outside your busiest selling hours. The checklist below from @ecombatman still uses the old October 30 date, which Meta later moved to November 20.

From November 20, the advertiser answers for whatever Meta's AI puts in its ads, so check every live ad before then.
