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.
Industry
Todd Bishop reports Amazon blocking Muse shopping access. Keep Amazon’s stated reasons attributed to Amazon and distinguish the access dispute from the separate Shopify and Instacart integrations.
Google Ads
Google’s Commerce Audience Sharing guidance sets out how eligible commerce media partners can share selected first-party audiences with brands or sellers, with links, permissions and approved-domain limits.
Amazon Ads
Isaac Gross reports an AI-assisted multi-country option in Sponsored Products setup. His post says expansion can include countries with eligible matching products, including products sold through Amazon Global Store.
Amazon Ads
James Howard reports an “often out of stock” message with alternative products, even while the item shown was available. It is a reported presentation test, not proof of an algorithmic penalty or quantified conversion loss.
Industry
Instacart’s new campaign demonstrates how it is presenting Clementine’s meal inspiration and shopping workflow to consumers. The assistant launched on 9 September, so this is campaign context around an earlier product announcement, not another launch.
Amazon Ads
Vita K. reports a beta offering to create a Sponsored Brands campaign alongside Sponsored Products setup. Other practitioner coverage appears to describe the same test, so it is one story.
Industry
Sam’s Club’s 17 September announcement expands its advertising proposition with predictive targeting and cross-channel measurement. The important buying question is how predicted propensity translates into incremental sales for your category.
Amazon Ads
Isaac Gross and Oleksandr Kovalov report expanded custom date selection at account level in the Ads Console. This may make it easier to investigate a past period when no report archive was handed over.
Walmart Connect
Walmart’s September announcement sets out expanded commerce intelligence, including marketplace visibility planned for next year. Reporting identifies an important limit: the relevant expansion is for brands operating both first-party and marketplace models, not a blanket offer to marketplace-only sellers.
Industry
Chris Kelly’s interview with Jen Wilson examines the addition of digital commerce to a remit already covering marketing, retail media, loyalty and personalisation. The transferable question is organisational: are the people buying traffic, managing the shopping experience and assessing customer value working from the same priorities? This is a strategic example, not new ad-buying functionality.
Amazon Ads
Amazon says sellers with products in enhanced-safety categories must hold USD 1 million in commercial liability cover from 2 November 2026, even if they do not meet the usual monthly sales threshold.
Amazon Ads
Mansour Norouzi shared an Amazon Ads settings screen for a seasonal targeting beta. The interface describes adding seasonal keyword and product targets to eligible campaigns, then pausing them after the season. Detailed eligibility and bidding behaviour remain unclear.
Google Merchant Center
Emmanuel Flossie observed supplemental-feed controls when the primary Merchant Center source used Google's automatic import. He explicitly notes that the option may have existed for longer, so this is a workflow observation rather than a dated launch.
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.
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 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.
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.
Google Merchant Center
Merchant Centre’s AI performance insights now cover Australia, Canada, India and New Zealand alongside the US, according to Google’s updated eligibility guidance.
Google Merchant Center
Google’s Business Agent setup now includes a route through the Google & YouTube app on Shopify, importing branding and support details for merchants to review before activation.
YouTube
YouTube is running a small shopping experiment that can show the same creator-tagged affiliate product from a different eligible local retailer.
ChatGPT Ads
OpenAI’s advertiser briefing adds card impressions and clicks for product-feed carousel ads, as well as product-level reporting via its Insights API.
Amazon Ads
Amazon’s guidance states that migration recommendations for legacy Product Collections will arrive in Campaign Manager in September, ahead of the format’s February 2027 deprecation.
Amazon Ads
The US Federal Trade Commission and 22 states sued Amazon on 31 August, alleging that undisclosed auction practices inflated advertising charges over several years.
Anthropic
Anthropic released reference implementations for shopping and merchant agents across retail, travel, telecoms and ticketing.
Amazon Ads
Amazon's updated Business Solutions Agreement, effective 24 August, restricts sellers from transferring contractual rights or obligations without Amazon's consent and from pledging them as collateral. The wording could affect account sales, aggregators, and financing structures tied to future Amazon disbursements.
Amazon Ads
Amazon Advertising Console is showing Last 12 months and Quarter-to-date presets in some accounts, extending analysis beyond the familiar short reporting windows without an export. Later sightings indicate that custom dashboard ranges can reach roughly 14 months in certain accounts, although granular limits on downloadable reports may still differ.
Amazon Ads
Eligible US YouTube creators can now tag Amazon products directly in Shorts, long-form videos, and livestreams through the YouTube Shopping Affiliate Programme. Viewers can move from creator content to an Amazon purchase without relying on a description link, and eligible brands may also connect a channel with an Amazon storefront.
Amazon Ads
Amazon DSP's automatic deal selection for Streaming TV and online video is expanding beyond the US to Canada, Mexico, Brazil, the UK, Germany, France, Italy, and Spain. The beta selects deals using the campaign's budget, audience, and dates, displays their pricing and availability before launch, and still allows manual additions.
