Google Ads promotions go automatic on 12 October, and your homepage becomes the ad copy

What Google Ads promotions change on 12 October#

A fox does not wait for the hounds to announce themselves. It reads the wind, and this week the wind says that on 12 October Google will start writing a line of your ad copy for you. Search Engine Roundtable reported on 5 October that Google has emailed advertisers to say automated promotions will be switched on by default, and because the setting is opt-out, Google opts you in unless you say no.

The mechanics of Google Ads promotions are plain enough. Google's own help page on automated promotions says the system finds and extracts promotional offers straight from your website, then attaches them to eligible campaigns. Eligible means active Search or Performance Max campaigns that have location assets linked and no promotion assets of their own. If you already run a promotion asset by hand, the automation has nothing to add. If you do not, it goes looking for one, and your homepage is the first hedgerow it checks.

Two details deserve a wary watch. First, the same help page says each sourced promotion runs for less than 24 hours and may be switched back on if Google verifies that the offer is still visible on your site. Google Ads promotions run on a rolling lease, not a one-off scrape, so a banner you forget to remove can keep returning. Second, Google also says only active, non-expired offers are shown, which sounds reassuring until you remember that Google is judging activity by what your page still says, not by what your finance team agreed last Tuesday.

That last line is the whole brief, delivered by a practitioner in three short sentences. Treat your site as the ad copy and the audit writes itself.

The trail is short. PPC News Feed logged the first sighting in early September, with the 24-hour re-verification rule already attached. Search Engine Roundtable followed on 7 September with the detail that Google Ads sources promotions, such as buy-one-get-one offers, from your landing pages. Google Ads promotions went from first sighting to default in forty days. Then came the date, and with it the sharp scent of a deadline that most accounts will meet half-asleep.

You can see what Google has added once it starts. Relevant Audience notes that you can filter the Assets view and look for Google AI in the Added by column. The same write-up flags a gap worth keeping in mind: Google has not said which countries the 12 October default covers. So if you run accounts across borders, do not assume the date applies, or fails to apply, to any one of them.

When a forgotten banner becomes an ad claim you never wrote#

Promotion assets are not new. They are the little offer lines that sit under a Search ad, and what many accounts still call a google ads promotion extension. Google's page on promotion assets describes them as highlighting sales and special offers beneath ads, and it describes the automated version as an AI-powered feature that sources, validates and displays deals from your website and other sources. What is new about Google Ads promotions is the author. Until now a person typed the offer, set the dates and signed it off. From 12 October, in an eligible account, a crawler can do all three.

Here lies the quiet quarry. A UK agency, UClimb, puts it bluntly: you do not build the asset, and you do not approve the wording. That is the authorship gap in a single line. Google's help page, meanwhile, still expects you to keep your website's promotional details current and to comply with ordinary advertising policy. So the machine writes the line, and the advertiser answers for it. Anyone who has carried a clipboard through a compliance review will feel the draught.

A cautionary note, hedged properly. An expired banner left on a homepage is the obvious route for a stale offer to reach a paid ad, because Google judges whether an offer is live by what your page still says. That is a reasoned risk, not a measured incident, and we found no published enforcement case on this feature. But the shape of the risk is not exotic. A stale banner is already a small lie on your own site. Fed into a paid ad, it becomes a small lie with a bidding strategy.

The contrast with the manual rules is instructive. Google's promotion assets page says occasion-specific promotion assets must be created or edited within six months of their start date to be eligible to serve. That is a freshness rule for human-written offers, and it runs on a calendar. The automated version runs on a clock measured in hours, driven by whatever your page happens to say. Different rules, same underlying question: is this offer real, current and findable by the customer who clicks?

Google's misrepresentation policy answers that question bluntly. It bars promising offers that are unavailable or not easily found from the destination, and it bars pricing practices that create a false or misleading impression of cost. The policy does not carve out an exception for offers written by Google's own automation. A claim in your ad is your claim, whoever held the pen.

Where the audit bites: dealers, regulated offers and google ads location assets#

Not every account meets Google Ads promotions with the same draught. Three kinds sit closest to the window.

Dealers and price-policy retailers#

Retailers who sell under a manufacturer's minimum advertised price agreement face the sharpest edge. Ecommerce Paradise sets out a hypothetical: a dealer lists a high-ticket item at $4,200, a site banner advertises ten per cent off, and an extracted promotion could surface a price of about $3,780 that undercuts the agreed floor. The numbers are the author's illustration, not an observed case, but the mechanism is sound. The same write-up says the setting reaches stores with a linked location asset, which is also the eligibility test in Google's own help page.

Anyone who prices in the UK#

The Advertising Standards Authority is clear that marketers are responsible for the prices in their ads, even where a third party sets them. Its guidance on price claims also expects the higher reference price to have been charged for longer than the promotional price, and says a comparison against a recommended retail price can mislead when that price differs significantly from the price at which the product is generally sold. Add the rule that ads must make clear the commitment needed to get the advertised price, and a banner stripped of its conditions begins to look risky.

The enforcement stakes are not theoretical either. The UK's consumer-protection regime under the Digital Markets, Competition and Consumers Act brought, as the Competition and Markets Authority's own blog explained, a prohibition on drip pricing of unavoidable fees. Law firm Osborne Clarke reports that the regulator can now impose fines of up to ten per cent of global turnover and has begun enforcement on pricing. Ten per cent is the ceiling, not the typical outcome. But it is a ceiling high enough to make a proofreading pass look cheap.

Regulated sectors, and an honest gap on Google Ads promotions#

What about iGaming and fintech, where an offer is a regulated act and Google Ads promotions could carry a bonus claim? We went looking for a Google statement on how automated promotions treat gambling bonuses or financial promotions, and found none. That is a gap, not a green light. Until Google says otherwise, the sensible reading is that the automation does not know your licence conditions, so keep the feature off where an offer line is a regulated claim, and ask your Google representative for the answer in writing. Operators who live in that thicket will recognise the habit: assume nothing, document everything. Our iGaming marketing and fintech marketing pages explain how we work in that terrain.

Keep it, switch it off or steer it: the automated promotions decision#

There are three honest options for Google Ads promotions, and none of them is a moral failing. The fox picks the path that suits the terrain, not the one the signpost recommends.

  • Clean the site first, then review.

The off switch, according to Ecommerce Paradise, lives under Assets, then account-level automated assets, then Advanced settings, where Automated Promotions moves from on to off. Google's help page confirms the same opt-out, and adds that you can upload specific promotions yourself if you need exact control over what is shown. That second sentence is the quiet third door: a manual promotion asset attached to an eligible campaign means the campaign no longer qualifies, which keeps the pen in your hand without switching a useful feature off for everyone.

Whichever door you choose for Google Ads promotions, measure it. Google's guidance suggests you segment your campaign reports by click type to see how customers interact with offers. That is the one place the automation leaves evidence behind, so use it. Our PPC and paid search service builds exactly this kind of control into account reviews, and our write-up on why the landing page is part of the ad covers the neighbouring problem of a destination that changes underneath your claim.

Five checks to run before 12 October#

The audit of Google Ads promotions is short enough to finish in an afternoon and dull enough to be worth it. Work down the list in order.

None of this audit of Google Ads promotions requires a new tool, a larger budget or a lawyer on retainer, though a quick word with your compliance lead is wise where offers are regulated. It requires the same thing the fox brings to every hedgerow: patience, attention and a refusal to let the undergrowth write the story.

If your account carries a mix of regulated and unregulated offers, the cleanest approach is usually to split by campaign, keep the automation where it is safe and switch it off where it is not. We apply the same logic when we review Google's AI Max migration and smart bidding exploration: a feature can be good for the account and still need a human to own it.

Google Ads promotions trade effort for authorship. Sometimes that is a bargain. Sometimes it is a stranger writing your sign. The date is fixed, the setting is findable, and the audit is an afternoon. That is a fair trade for keeping your own voice in your own ads.
