If your company buys Meta ads, then from November 20, 2026, any mistake Meta's own AI makes in your ads is your legal problem, including edits from features you never knowingly switched on. Meta's revised Commercial Terms add an AI Features section that says the features "may make mistakes" and that "you are solely responsible for and assume any and all risks associated with such AI features." The terms bind on continued use. Nobody signs anything. That leaves marketing, legal and procurement about three weeks to decide which AI enhancements stay on, what your crawler policy is and how your agency contracts split the risk.
The date moved once already. Meta originally set October 30, then pushed it back. A spokesperson told Reuters on October 23 that the company needed time "to explain to our partners and stakeholders what's changing and what's not." Meta did not say the text would change. Both the Commercial Terms and the Self-Serve Ad Terms pages now carry the banner "These updates will go into effect on November 20, 2026."
What Meta's New AI Features Clause Actually Says
The new clause makes the advertiser carry the risk of anything Meta's AI produces or changes in an ad. The Self-Serve Ad Terms preview puts it plainly: "Some of our products include automated features that allow Meta to assist you with your Ad Creative," followed by the same sentence about the advertiser being "solely responsible" and assuming "any and all risks." It sits beside the existing line that you are "solely responsible for the Order, Ad Creative, targeting decisions, and ad placements."
Under the older wording, according to Adweek's reporting as summarized by PPC Land, advertisers answered for AI output only when they chose to use Meta's AI creative tools. The new section drops that condition. PPC Land notes it could not match Adweek's quote of the old wording to the March 2024 terms, so treat the before-and-after comparison as reported rather than confirmed.
The preview terms say nothing about which AI features are on by default or how to turn them off. Neither terms page mentions Advantage+ by name. The contract assigns the risk, and the settings that decide how much of it you take on live in Ads Manager.
The Indemnity and Liability Cap Are Not New
The broad indemnity and the liability cap are already in the terms you accepted. The current Commercial Terms, dated March 6, 2024, already require you to "indemnify and hold us harmless from and against any damages, losses, and expenses of any kind" arising from third-party claims. They already cap Meta's liability at "the greater of one hundred dollars ($100) or the amount you have paid us in the past twelve months." The November 20 preview keeps both.
What changes is the set of risks those clauses now reach. The AI Features clause adds content that Meta's own tools generate or modify to the risks you assume. If an AI-generated product image misstates a feature, or an auto-translated headline makes a claim your regulator objects to, the contract says the risk was yours and you indemnify Meta for it.
The preview also lets Meta "modify, limit, suspend, or discontinue any commercial products, services, and features" at "any time without prior notice or liability." Read together, Meta can change what its AI does to your ads without telling you, and you still own the result.
Features Already Running in Your Account
Meta's AI has already edited live ads in ways advertisers did not ask for. In July, Business Insider reported that REI ran an Instagram ad showing a bicycle with two handlebars after Meta automatically enrolled it in an AI feature. Meta's reply then was the policy now being written into the contract: its terms say "AI can make mistakes and that it is the advertiser's responsibility to review the AI outputs."
The agency Exverus reported that Meta's AI added sitelinks, translated copy and generated images and carousels, sometimes where nobody had enabled those features. Its paid search and social specialist Ryan Adams said: "Meta auto-applies the enhancements, and many of the options are tucked away in hidden or collapsed menus." Bookshop.org said one of its ads was "'enhanced' (or ruined, really) by Meta without our knowledge." A Meta spokesperson said individual Advantage+ features can be switched off in Ads Manager, but did not say whether an advertiser is liable for a feature it never turned on.
The next default flip lands this week. Meta's advertiser notice says that "Starting October 28, 2026, we'll add product browsing to your existing ads" unless you opt out, per PPC Land's copy of the notice. Product browsing can send someone who taps your ad to a Meta-hosted page with product information and "personalized suggestions" before they reach your site. Meta cites a 3% average conversion lift from an August 6-21 experiment across about 117,700 advertisers, without defining which conversions it counted. The notice covers existing ads only and does not say whether new ones default on.
Turning things off once is not enough. Agency JumpFly warned in August that "replacing the creative, changing the ad format, duplicating an ad" can reselect recommended enhancements. It points to account-level defaults under Ad account settings, then Creative features, as the place to stop new features from being enabled automatically.
The Crawl Clause Covers Your Website
The same terms let Meta crawl any site associated with your business, and they make no promise to honour robots.txt. The preview authorizes Meta "(or any entity acting on our behalf) to use automated software (such as web scrapers, bots, robots, spiders, crawlers, and user agents)" and to "create test credentials to access, index, cache, analyze, collect, retrieve, or crawl" those domains. The stated purpose is "to provide, develop, improve, research, and maintain advertising and business products."
That purpose line has already been edited once. The original version listed "train" among the uses. Search Engine Journal reported that Meta removed the word, a revision Nieman Lab reported on October 17, and that spokesperson Daniel Roberts told The Verge the crawling terms "only applied to our ads and business products." Matt Topic of Loevy & Loevy told Nieman Lab, "I think 'develop' is broad enough to include 'train,'" and noted that "business product" is not a defined term.
The scope is wider than ad buyers. Relevant Audience reported that the terms cover any business that keeps using Meta's business products, including one that only manages a Page. Meta says robots.txt still expresses your preferences. Its own crawler documentation says Meta-ExternalAgent crawls for "training foundation AI models or improving products by indexing content directly." So one robots.txt token covers both uses: block it and you lose indexing too, allow it and you allow training. It also says meta-externalfetcher "may bypass robots.txt rules" for user-requested fetches.
The Arbitration Opt-Out Window May Already Be Closed
The 30-day arbitration opt-out matters less than it looks for most existing advertisers. The preview requires US businesses to arbitrate commercial claims individually and says that to opt out, "you must notify us as set forth below within 30 days of the first acceptance date of any version" of the terms containing an arbitration provision. The notice goes by mail to Meta Platforms in Menlo Park.
PPC Land estimated that the window would close around December 20 if acceptance happens on November 20. That assumes the clock starts with this version. But the current terms already contain an arbitration clause with the same 30-day, first-acceptance language. If your company accepted an earlier version years ago, your window probably closed then. A legal entity that first accepts on or after November 20, such as a new subsidiary opening its own ad account, may still have one. Ask counsel to check which entity holds each ad account and when it first accepted.
What to Do Before November 20
The work splits across marketing ops, legal and web, and most of it can start today.
This Week:
- Decide on product browsing before October 28. If you want taps to go straight to your site, use the opt-out in Meta's notice or switch the setting off per ad in Advantage+ Creative and Destination settings.
- Export a list of every live ad with Advantage+ creative enhancements enabled, account by account. Set account-level Creative features defaults to off for anything your brand or legal team has not approved.
- Pull five recent ads per account and compare what ran against what was approved. If Meta changed text, images or translations, you have evidence for the agency conversation below.
Before November 20:
- Have counsel read the AI Features clause next to your existing indemnity exposure. Regulated claims (financial products, health, pricing) are where an AI rewrite turns into a third-party claim.
- Re-paper agency contracts. Your agency likely toggles these settings. Decide in writing who reviews AI-modified creative and who carries the cost when an enhancement causes a claim.
- Set your crawler policy deliberately. Decide whether Meta-ExternalAgent is allowed on product pages, gated content and login flows. Remember that the terms authorize test credentials, so sign-up walls are in scope.
- Check the arbitration position per legal entity rather than assuming a December deadline applies to you.
After November 20:
- Re-audit enhancements after every creative change, duplication or format switch. JumpFly's finding means a one-time cleanup decays.
The Bigger Picture
Meta's risk allocation was written for a world where the advertiser wrote every word: a $100-or-twelve-months cap on Meta's side, an uncapped indemnity on yours. Generative features change who authors the ad while the allocation stays put. The image-generation vendors went the other way, and Adobe, Google and Getty now indemnify customers for some AI output. Meta's terms put that risk on the advertiser instead. Under the updates clause, disagreeing means you stop using Meta's products for commercial purposes. What you control is how much AI-modified creative runs under your name, through Ads Manager settings and your agency contract.
Get the enhancement inventory done before October 28, while the product browsing opt-out is still open.
