The changes that matter to advertisers, with the sources behind them and a practical next step. Pick a topic and catch up at your own pace.
Meta Ads
A documented new Meta ad setup showed creative-enhancement switches off; it is a useful workflow observation, not evidence of a platform-wide default.
Industry
Allison Schiff’s PatientPoint reporting explores advertising in medical-office settings. This is specialist inventory, and the reported network footprint is not a count of new screens installed this week. Healthcare advertisers considering the channel should interrogate audience definitions and measurement before treating proximity to care as evidence of effectiveness.
Google Ads
Natasha Kaurra highlights destination options involving a website and Business Profile, while noting that the functionality is not entirely new. For local advertisers, check where the customer lands and whether calls, forms and visits are measured appropriately. Convenience and qualified demand may not point to the same destination.
Industry
Jessica Davies and Sara Guaglione report on Google’s existing AI publisher-licensing pilot. The development is the reporting and detail, not a newly launched September programme.
Industry
Hugo Huijer reports a sharp fall in organic product carousels across the EEA markets represented in Productrise’s query sample. He explicitly thanks Christian Kunz and Mathias Noyez for raising the issue earlier.
Google Ads
Google has confirmed a very early Shopping-ad experiment that adds a label showing the days remaining in a sale; no broad availability or advertiser control is established.
YouTube
YouTube’s Shopping Affiliate programme is expanding into the Netherlands with bol, connecting creator product recommendations with shopping. Google announced the move on 11 September; bol followed on 14 September. This is a dated catch-up on a relevant retail development.
Amazon Ads
Amazon is piloting managed ChatGPT advertising through its DSP with selected US advertisers, according to Peter Adams' 10 September reporting for Marketing Dive. The report names Delta Vacations among the participants.
BigQuery
BigQuery introduced AI.CAUSAL_EFFECT in preview on 10 September. The function compares results after an intervention with a forecast based on earlier observations, letting analysts examine a change using time-series data already in their warehouse.
Industry
A coalition publicised by noyb calls for automated privacy signals as part of EU reform. The 10 September letter is an advocacy position on a proposed policy approach, not an announcement that website consent requirements have already changed.
Google Ads
Google's 10 September measurement announcement introduces Data Strength Uplift, a metric for conversions recovered through first-party data. It gives advertisers another way to examine measurement coverage, with an important distinction between capturing a sale and creating one.
Industry
IAB's September outlook raises its projected 2026 US advertising growth to 12.3%, up from 9.5% in January. The forecast draws on more than 200 brand and agency buyers and offers planning context across channels.
Microsoft Advertising
Microsoft describes Copilot in Curate as contextual guidance for curation workflows; it is not a new self-service buying control for every advertiser.
Snapchat Ads
Snap announced on 10 September that Dynamic Product Ads for Sponsored Snaps are available to advertisers globally. The placement brings catalog products into Chat as part of its Commerce Power Pack.
Snapchat
Snap's 10 September announcement places Omnichannel Optimization in alpha. It combines web and app purchase optimization within a single campaign.
Snapchat
Snap announced Third-Party Web Optimization in open beta on 10 September. It combines first- and third-party signals to optimize toward third-party purchase outcomes.
Snapchat
Snap's 10 September Commerce Power Pack includes Value Optimization in beta for web and app advertisers. It is designed to optimize toward purchase value and return on ad spend.
Amazon Ads
Will Haire shared Amazon's Seller News notice describing a revised coupon-creation process: reuse a previous setup, save a draft and review the coupon before submission. The notice shown in the screenshot is dated 9 September 2026.
Amazon Ads
Amazon's developer release feed dated 9 September describes a performance-data checkbox for Sponsored Ads bulk exports. It is selected by default; omitting performance data can make exports faster when only structure and settings are needed.
Google Ads API
Google says developer tokens were sunset on 9 September 2026. Google Ads API access now follows the Cloud project behind an application's credentials, making project ownership and access levels the immediate checks for integration teams.
Google Ads
Google will disallow gambling-promoting content targeting Croatia from 7 October; the notice does not prohibit online gambling advertising itself.
Google Merchant Center
Brodie Clark is credited with observing additional sections in Merchant Center's AI performance reporting. Barry Schwartz's 9 September coverage identifies Brodie's observation and screenshots; Google's current documentation explains the report's scope.
Pinterest's 9 September Men's Trend Report highlights interests around offline activities, hosting, grooming and workwear. For relevant advertisers, these are leads for creative research and testing rather than population-wide forecasts of what men will buy.
Google Ads
Google’s regional Search documentation now describes the EEA experience, with its 18 September changelog adding local-business query support for aggregator and supplier units. Some related travel experiences date back to 2024: the whole layout should not be described as newly launched.
Google Ads
Adriaan Dekker describes a Product Value Optimization beta and explicitly credits Tiago Goncalves. Treat this as a lead for eligible accounts, not a general release.
Meta Ads
Earlier coverage describes changes to Threads profile analytics. Treat the material as an organic-account reference and keep its metrics separate from paid campaign reporting.
Industry
An open letter published by Shoptimised sets out CSS Group's position on Shopping access and DMA enforcement. The signatories call for reciprocal visibility and testing of proposed changes. This is an industry position, not an enacted advertising rule.
Meta Ads
Meta announced Muse, a personal AI agent with shopping and task-completion capabilities, on 8 September. The US rollout introduces another potential route from a customer's request to a purchase, rather than a new ad-buying placement.
Google Ads
Thomas Eccel reports seeing AI Dashboards in some Google Ads accounts. The interface can create visual reports from text prompts and add an AI-generated summary. This supplies a reported availability update to the earlier dashboard preview, without establishing a general rollout or validating the suggested explanations.
OpenAI
OpenAI has announced ChatGPT Images 2.5, with targeted image comments, sketch references and templates for formats including product photos. The company says it improves reference preservation and consistency across edits, with rollout across ChatGPT, ChatGPT Work and Codex.
