Google's AI now runs your ad account by default. You're still the one legally on the hook.

On July 1, 2026, Google rewrote the Google Ads Terms of Service for the first time in roughly eight years — and every existing account was bound to it automatically, with no checkbox, no re-login, no re-acceptance click. The headline change: Google's automated systems now have standing, default authorization to generate, select and format your targets, ads and destinations. The part almost nobody is talking about: none of that shifts legal liability off the advertiser. If the AI writes a misleading claim or skips a disclosure label, that's your problem, not Google's.

What actually changed on July 1, 2026

Per Search Engine Land's reporting on the update, the new terms read: "Customer authorizes Google and its affiliates to serve ads, including through the use of automated program features to format, select, or generate targets, ads, or destinations on Customer's behalf." That's a meaningful shift from the prior terms, where many automation features were framed as opt-in settings an advertiser could toggle. The new language authorizes automation as a default condition of running Google Ads at all — a change Common Thread Collective's coverage frames explicitly around AI automation for e-commerce accounts.

The scope is broad by design: it covers text and URLs typed into conversational campaign-creation tools, and the sites and accounts advertisers authorize Google to crawl for automated setup — the same underlying mechanism behind Dynamic Search Ads and Performance Max, and now AI Max for Search.

Who's liable when Google's AI writes your ad?

You are. Common Thread Collective's analysis of the new terms is direct on this point: advertisers remain fully responsible for reviewing, approving, editing or removing anything Google's systems generate automatically. The automation is a convenience Google is granting itself by default — it is explicitly not an assumption of responsibility. If an automatically generated headline overstates a claim, targets an audience it shouldn't, or a Performance Max asset group pulls copy from a page that's since changed, the compliance exposure sits with the advertiser's account, not Google's.

The new AI-disclosure labels — and why the compliance burden landed on you

Layered on top of the terms change, Google began rolling out disclosure labeling for AI-generated or AI-modified ad creative between July 9–13, 2026, per Search Engine Journal. Ads across Search, YouTube and Discover now carry a "How this ad was made" panel, reachable from the three-dot menu or an info icon. Google auto-applies the label when its own generative ad tools were used — but as ppc.land's coverage of the change puts it, Google shifts the labeling liability entirely to advertisers when an outside AI tool was used instead: you have to self-apply the disclosure through a new control, and getting that wrong is on you, not the platform. The requirement is anchored to jurisdictions with AI-transparency laws — the EU, India and New York State currently — so if you run ads in any of those markets, this isn't optional.

What this means right now if you're running Performance Max, AI Max or DSA

There's some near-term relief on timing. Google had planned to auto-migrate all Dynamic Search Ads campaigns to AI Max for Search by September 2026, but pushed that deadline to February 2027 after advertiser feedback about disruption during Q4 budget planning, according to Search Engine Roundtable, with Google Ads Liaison Ginny Marvin cited as the source of that change. That's a genuine reprieve for anyone mid-quarter. It doesn't apply to everything, though — campaigns using Automatically Created Assets and campaign-level broad match are still on track to auto-upgrade starting September 2026, an earlier and separate deadline from the DSA sunset.

Industry reaction has been mixed at best. AdSQUIRE founder Anthony Higman has argued publicly that the rewritten terms further erode what he considers the two pillars advertisers actually paid for in Google Ads: relevance and control. Whether or not you share that framing, the practical upshot is the same — automation default-on plus liability default-yours means the advertiser side of the relationship needs more active governance, not less, even as the platform asks for less manual input.

A practical governance checklist for the next 90 days

• Audit what's currently auto-generating in your account — ACA assets, Performance Max asset groups, any conversational campaign builds — and confirm a human actually reviewed the last batch, not just the first one.
• Check your disclosure-label settings if you use any outside AI tool for ad creative and you run ads in the EU, India or New York — this is a self-serve control you have to activate, not something Google does for you.
• Calendar the September 2026 ACA/broad-match auto-upgrade separately from the February 2027 DSA-to-AI-Max deadline — they are not the same clock.
• Build a standing review cadence for AI-touched assets into your account management process, the same way you'd review a junior team member's output before it goes live.
• Reconcile automation output against your actual offers and pricing pages regularly — automated targets and destinations can drift out of sync with a site that's since changed.

None of this is a reason to turn automation off — Performance Max and AI Max earn their place in a performance marketing account when they're managed, not left unattended. It is a reason to stop treating "AI generated it" as the end of the review process instead of the start of one.

Frequently asked questions

Did I have to agree to Google's new Ads Terms of Service?

No. The July 1, 2026 update applied automatically to every existing Google Ads account with no re-acceptance click, login prompt or checkbox. If you run Google Ads, you are already operating under the new terms whether or not you've read them.

What exactly does the new Google Ads authorization language cover?

The rewritten terms authorize Google and its affiliates to use automated program features to format, select or generate targets, ads or destinations on the advertiser's behalf. In practice this covers tools like Performance Max, AI Max for Search and conversational campaign-creation features that read your site, feed and inputs to build campaigns automatically.

Who is legally responsible if an AI-generated ad makes a misleading claim?

The advertiser is. Google's terms are explicit that automation does not shift liability: advertisers remain responsible for reviewing, approving, editing or removing any AI-generated campaigns or assets before they run, and for correctly applying required AI-content disclosure labels.

Do I need to add a disclosure label if I use an outside AI tool to make my ad creative?

Yes, in jurisdictions with AI-transparency requirements such as the EU, India and New York State. Google auto-labels ads built with its own generative tools, but if you use a third-party AI tool for images or video, you're responsible for applying the disclosure yourself through the available ad controls.

The takeaway

Google didn't ask permission to hand its AI more default control over your account — it just changed the terms and moved on. That's not a reason to panic, but it is a reason to stop treating your ad account as something that runs itself safely in the background. The accounts that come out ahead here are the ones that keep a human explicitly in the loop on everything AI touches, calendar the real deadlines instead of the rumored ones, and get the disclosure settings right before a regulator or a platform review finds the gap first.
