ChatGPT ads hit Europe, Google kills legacy Search campaigns in September
Four things moved in digital advertising this week, and none of them were optional. OpenAI is bringing ads to European ChatGPT users this month. Google locked in a September date for forcing Search campaigns into AI Max. CMOs still cannot connect AI visibility scores to revenue. And Apple opened Maps ad bookings before a single ad has actually run.
ChatGPT ads arrive in Europe, contextual only
OpenAI emailed European users on Saturday, 15 August confirming ads will appear on Free and Go plans later that month. Plus, Pro, Enterprise, Business, and Education tiers stay ad-free. The sender is OpenAI Ireland Limited, which makes the Irish DPC the relevant regulator for EEA and Switzerland complaints.
Targeting at launch is contextual only: the current conversation topic, general location, and device type. Past chats and memories are excluded. OpenAI’s help centre states personalised ads are “not initially available” in the EEA or Switzerland, held behind a later opt-in prompt. Advertisers receive aggregate views and clicks only, with no access to chats or history. Ads sit below the response, labelled sponsored, and do not appear in the Atlas browser or Temporary Chats.
Separately, automatic advanced matching becomes the default on existing ChatGPT web pixels on 17 August.
The practical implication: with behavioural targeting off, context hints, ad copy, and landing page carry the full targeting weight in Europe. Anything built on US behavioural signals needs rewriting, not duplicating.
Google’s AI Max migration is mandatory from 1 September
From 1 September, Google automatically upgrades Search campaigns running campaign-level broad match or standalone automatically created assets into AI Max. The rollout is gradual across the month. Campaigns move in place with equivalent settings, and existing brand inclusions and exclusions carry over.
There is no route back. Google already blocked creation of those legacy structures across the Ads interface, Ads Editor, and API on 3 August.
Dynamic Search Ads are on a slower timeline: in-account warnings from September, reminders on 15 January 2027, automatic migration through February 2027. After that, new DSA ad groups cannot be created. API versions released after 1 September drop support for legacy DSA entities entirely, with older versions sunsetting around September 2027.
Audit any account still running broad match at campaign level or standalone automatically created assets before August ends. After that, the migration happens whether you have set a baseline or not.
73% of marketers are buying AI visibility tools, nobody is connecting them to revenue
Digiday reports that 73% of marketers have invested in tools to monitor AI visibility. Share-of-model products from Semrush, Profound, and Scrunch estimate presence without connecting it to sales. Roast’s John Barham told Digiday: “There is no one tool out there that can paint you a picture of the universe.”
The scale of the problem is growing. Demandbase data puts ChatGPT-referred visits to B2B brands up 303%, from roughly 645,000 in June 2025 to 2.6 million in June 2026. That traffic growth lands straight back into the same attribution gap.
The teams making progress are modelling rather than reporting. Rippling triangulates Profound and AirOps visibility data, ChatGPT ads conversion data, branded and unbranded search traffic, and a bespoke MMM built on Google’s open-source Meridian. Roast uses Google’s Causal Impact model. The IAB published standard visibility measurement guidance at the start of August.
If your AI visibility reporting stops at a share-of-model score, expect a board question you cannot answer. The fix is building a modelling layer, not buying another dashboard.
Apple Maps ad booking is open, but no ads are live yet
Booking opened on 14 August for US and Canada businesses at ads.apple.com/maps. Delivery has not started. Apple says ads go live “soon” with no confirmed date, so campaigns built now accrue nothing yet.
The launch promotion returns 15% of spend as a monthly statement credit for up to a year, capped at $1,000 per month, for businesses booking by credit card before 11 October 2026.
Two placements are available: Suggested Places on the search screen before a query, and search results after one. Apple claims over a billion business searches in Maps each month, says one in two results in a user action, and cites GWI data putting Gen Z and millennials at 57% of Maps users. Businesses must have claimed their location through Apple Business first.
For anyone with multi-location clients, the Apple Business claiming step is the slow part. Get that done now and treat the 11 October credit deadline as the real booking date.
