Industry
The FTC, Utah and Nevada allege that Lens.com advertised contact-lens prices without mandatory fees and misled customers about AutoRefill enrolment.
Industry
Google’s September 2026 spam update began on 24 September and had no completion notice by the review cut-off; reported volatility was not Google-confirmed.
Industry
Reporting says Judge Amit Mehta dismissed Chegg and Penske Media’s AI Overviews antitrust claims without prejudice, leaving open possible amended claims.
Industry
Google updated its guidance to stress manual fact-checking and review of AI-generated content, including titles, meta descriptions, structured data and alt text.
Industry
Judge P. Kevin Castel denied Google summary judgment on main ad-tech claims from Gannett, Daily Mail and a publisher class, allowing the dispute to continue.
Industry
Chris Long found AI Overviews on 93 of 100 enterprise brand names tested, while DemandSphere and Ahrefs reported rises using different methods and query sets.
OpenAI
OpenAI announced GPT-6.1 Sol and plugin improvements including sidebar homes, interactive panels and discovery in directories and conversations for all plans.
Industry
Reuters reports that Google asked the EU General Court to annul and suspend DMA decisions on search-data sharing and rival AI-assistant access in Android.
OpenAI
OpenAI introduced Dots, always-on agents with cloud computers and connected apps, plus ChatGPT Space for shared work, with access varying by plan and market.
Industry
Graphite and Similarweb analysed more than 95,000 ads and 8,000 landing pages, reporting early ChatGPT Ads findings alongside important methodology limits.
Anthropic
Anthropic says Claude Sonnet 5.5 complements Opus 5.5, claiming more than 30% faster operation and up to 30% lower cost for most work than Sonnet 5.
Industry
Microsoft’s 25 September announcement introduces Home and Code with gradual Frontier access, while Autopilot is scheduled for a private preview at the end of the month. For marketing teams, assess a defined research, reporting or production workflow before assuming the whole experience is available.
Anthropic
Claude’s 24 September announcement brings personal connectors into channel workflows, initially through a Team beta, with Enterprise to follow. Review what a request can access and what the resulting channel message reveals to other members.
Industry
Reporting credits Lluc Penycate with a hotel-search side-panel observation. It is an organic search-interface test; no Hotel Ads buying change or universal rollout has been established.
Google Business Profile
Coverage attributes to Ayman Ali an observation of entering business hours through text. It could reduce repetitive profile administration where available.
OpenAI
OpenAI’s 23 September release notes describe Voice Work across documents, presentations, spreadsheets, apps and browser work. Access depends on the relevant Voice and Work capabilities, permissions and usage limits.
Industry
The partnership announcement describes Comscore demographics entering forecasting, pacing and posting workflows through datafuelX. That may reduce friction in working with different TV measurement currencies.
Industry
The UK Competition and Markets Authority proposes annual search-choice prompts and the inclusion of eligible AI assistants. The consultation runs to 9 October.
Industry
Trigify’s 23 September notice says its team is joining HubSpot and the standalone service will retire. It is not a migration of the product into HubSpot.
Anthropic
Anthropic announced Opus 5.5 on 22 September, with changes to capability, pricing and effort controls. Marketing teams should compare it on a repeatable task such as analysing an export or preparing a source-backed brief, including review time and retries in the cost.
OpenAI
OpenAI’s announcement makes Sol and Luna available through ChatGPT Work, Codex, and the API, with access varying by plan; it also distinguishes these surfaces from Chat. For marketers, compare the models on repeatable analysis and production tasks, measuring factual quality and review effort alongside cost.
Industry
A WebKit bug report filed on 21 September documented blocked requests involving adsrvr.org and identity domains on iOS 27; Apple said it was investigating.
Google Ads
Sachin Patel has documented text-link ads and descriptions in AI Mode. Brodie Clark’s ongoing format guide also records paid and organic product presentations, including earlier examples.
Meta Ads
Coverage of Muse’s desktop and connector expansion provides a practical productivity reference beyond the earlier general agent demonstrations. Start with a bounded task such as preparing research or gathering reporting inputs, then inspect access permissions and the resulting work.
Industry
David Vargas shares a practitioner observation that raffles can stimulate app installs. A prize can change the mix of people installing, so headline install volume alone cannot establish whether the tactic improves a sustainable acquisition programme.
Google Merchant Center
Google Merchant Center now documents Merchant API uploads for product-review data, adding a programmatic route alongside established feed-delivery methods.
Google Ads
Google’s current guidance supports product-review uploads through Merchant API. Teams maintaining feeds can assess whether this reduces manual handling, while checking review-programme requirements and validation. Documentation coverage does not by itself establish that the underlying capability launched this week.
Google Ads
Mike Ryan’s follow-up analysis reports diverging CPC trends between budget-limited and non-limited campaigns after Google’s change to target-based bidding. Google dates the rollout to 17–27 August, so this is new analysis of an earlier change.
Google Ads
Google’s guidance describes review volume, country coverage, a rolling 24-month window and the rating threshold for ads. Eligibility is more nuanced than a universal “100 reviews unlocks stars” rule. Check the current requirements before building a review-collection plan; this is a reference, not a verified new policy.
Google Ads
Google’s guidance recommends safeguards including CAPTCHA, double opt-in and server-side validation. Review where invalid submissions enter your process, then measure qualified leads rather than celebrating a cheaper form fill. These are practical safeguards, not a promise that Google’s filters or your form will eliminate all fraud.
