Meta’s own help notice now says the updated Meta Commercial Terms and Self-Serve Ad Terms take effect on November 20, 2026, in every language edition we checked. A capture of the same notice from October 16 said October 30. The legal pages themselves are split: the UK-English, German, French and Spanish previews we checked still print October 30. Meta gave no reason and made no announcement that we found.
When do Meta’s updated Commercial Terms take effect?
Meta’s help notice says: “From November 20, 2026, updated versions of the Meta Commercial Terms and the Self-Serve Ad Terms will take effect.” The same notice said October 30 on October 16. The terms previews disagree by language edition: US-English and India-English say November 20, while UK-English, German, French and Spanish still say October 30.
Which date does each page show today?
We rendered each page on October 23. The table lists editions (locale versions of a page), not countries or customers. Which edition governs a given account is not stated on the pages. For French we checked the France and Canada editions, and for Spanish the Latin American and Spain editions.
| Page | Edition | Effective date shown today |
|---|---|---|
| Help notice | en_US, en_GB, de_DE, fr_FR, fr_CA, es_LA, es_ES, en_IN | November 20, 2026 (in each language) |
| Commercial Terms preview | en_US, en_IN | November 20, 2026 |
| Commercial Terms preview | en_GB, de_DE, fr_FR, fr_CA, es_LA, es_ES | October 30, 2026 (in each language) |
| Self-Serve Ad Terms preview | en_US, en_IN | November 20, 2026 |
| Self-Serve Ad Terms preview | en_GB, de_DE, fr_FR, fr_CA, es_LA, es_ES | October 30, 2026 (in each language) |
The archive shows the move. A capture of the US-English preview from October 17 says October 30. A capture from today says November 20, and the UK-English page still said 30 October when we rendered it today. Comparing the two US-English texts, only the banner and the Effective Date line changed. The AI wording is identical.
We can bracket the change but not date it. An archived copy of the US-English Commercial Terms preview from the evening of October 18 (UTC) still gave October 30, so that page changed between October 18 and October 23. The US-English Self-Serve preview changed between October 17 and October 23, and the notice after October 16. The coverage we found, all published on October 22, gives October 30. Adweek’s October 22 report says the terms come into play “Oct 30”, and PPC Land, citing the News/Media Alliance open letter, reports that the letter asks Meta to withdraw the terms “before their claimed effective date of October 30, 2026.”
Acceptance works by continued use. The terms in force and the preview both say that if you keep using Meta’s products for business or commercial purposes “after any notice of an update to these Commercial Terms, you agree to be bound by them.”
What does the new AI Features section say?
The section sits in the Commercial Terms preview and was already in an October 6 capture. It says AI features “may make mistakes and may not always produce accurate, complete, or suitable results.” Then: “You are solely responsible for and assume any and all risks associated with such AI features and any resulting Content, including evaluating the suitability of any Content for business or commercial purposes.” The Self-Serve preview carries a parallel clause for Ad Creative. Meta’s notice says the Ad Creative Generative AI Terms (effective May 6, 2024) are folded into the Self-Serve Ad Terms.
| Item | 2024 Ad Creative Generative AI Terms | New AI Features section |
|---|---|---|
| Scope | GenAI features offered through Self-Serve Ad Interfaces or the Marketing API for ad creative | Products “powered by artificial intelligence, machine learning, generative AI, or other automated products or features” across Meta Company Products |
| Condition on responsibility | “you may choose to use the Ad Creative AIs in your sole discretion”; “if you use or publish any Output” | None in the text: “solely responsible for and assume any and all risks” |
| Watermark sentence | “You must not alter or remove any watermark or content-authenticating metadata that may be generated with Output.” | “…watermark or content-authenticating metadata generated by AI in connection with Content.” |
| How you agree | Clicking “accept” or using the tools | Continued business use of Meta products after notice |
Does the AI clause depend on whether you switched a feature on?
The text contains no such condition. Our reading is narrow: the 2024 wording tied responsibility to choosing a tool and using or publishing its output, and the new sentence does not. Adweek reads it more broadly, saying advertisers will be responsible for whatever the features create “including features Meta switches on.” According to Adweek, a Meta spokesperson did not directly address that point and added that advertisers can turn off individual Advantage+ features in Ads Manager at any time.
Two sentences the coverage we read did not mention
The watermark rule is not new: the 2024 Ad Creative Generative AI Terms had it. What changed is the reach: it now covers metadata “generated by AI in connection with Content,” not only Output of the ad creative tools, and neither preview defines “content-authenticating metadata”. Teams that re-export Meta-generated creative should know what their workflow keeps. For what one AI vendor’s marks do and do not show, see our piece on Claude’s watermark and why contact is not authorship.
The other sentence is new to the preview: “You are solely responsible for the acts or omissions of any third-party software or service that you use or authorize in connection with your use of Meta Company Products for any business or commercial purpose.” The terms in force, dated March 6, 2024, have no such sentence. The sentence does not name AI assistants. Meta’s own release, the Meta Ads MCP connectors, launched in April to let outside assistants such as ChatGPT and Claude read and change campaigns. We quote the text and draw no legal conclusion about which tools it covers.
What to audit before October 30
Ad buyers quoted by Adweek describe the practical risk. Ryan Adams of Exverus told Adweek that “Meta auto-applies the enhancements, and many of the options are tucked away in hidden or collapsed menus.” He added that if each is not unchecked, “the enhancements still apply.” Kayla Loecker of AdCellerant told Adweek her team turns off Meta’s default AI automation across every campaign.
- Check every enhancement option in Ads Manager, including the hidden or collapsed menus Exverus describes.
- Keep the original assets so any AI variant can be compared with them.
- Record which enhancements were on and when. PPC Land wrote on October 22 that Meta has not said whether version-level reporting will show which AI-altered variants ran.
- List every third-party tool or agent with access to the account.
- Since Meta’s pages disagree, plan for October 30 until they agree.
