AI Overviews launched in France, triggering noticeable organic click drops for informational publishers. Search Console tracking across multiple French properties showed a sudden decline in CTR as AI Overviews resolved quick-answer queries at the top of the SERP. Here is a tweet from Lily Ray showing a drastic drop in clicks for a French site that coincides with this day.
Google released Gemini 3.8 Flash, making it available as a selectable option in the AI Mode model dropdown for paid subscribers. A new model option in AI Mode functions much like an algorithm update: the model's advanced reasoning allows it to directly resolve complex queries with fewer clicks to external sites, while simultaneously recalibrating which websites it predicts will provide the most valuable deep-dive source material.
Google published major updates to the Universal Commerce Protocol (UCP) specification, refining how e-commerce sites declare inventory, checkout workflows, and machine-readable product schemas for agentic shopping.
Google introduced direct controls in Search Console for Generative AI visibility. Webmasters can now monitor and set explicit preferences for how their content is summarized and utilized across Google's generative search features and AI Overviews.
Interactive visuals and live code-generated simulations began rolling out directly within AI Overviews, expanding beyond AI Mode. Searchers can interact with dynamic charts, calculations, and simulations inside the SERP without needing to click into full AI Mode.
Google launched the August 2026 Spam Update, completing on August 21. Google announced this as a global update affecting all regions and languages. This was an impactful update. There are many reports of sites suffering deindexing of AI generated content done at scale. Here is a good post from Glenn Gabe with his observations and case studies.
Data from Promptwatch showed that ChatGPT has almost entirely stopped citing Reddit. AI Mode is also showing significantly fewer Reddit responses, dropping to just 1.5% of monitored answers over the past 7 days (while AI Overviews citations have decreased only slightly). This represents a notable shift in how generative search engines weight forum and UGC discussions for informational queries.
Gemini in Chrome with Autobrowse rolled out to Android users in the US. Autobrowse allows Gemini to autonomously navigate websites, complete multi-step tasks, book tickets, and fill out forms on behalf of the user, marking a major milestone in agentic web navigation.
Gemini 3.7 Flash rolled out to power AI Mode for paid Google AI subscribers. Model updates feel like algorithm updates because they improve the quality of AI answers, meaning fewer clicks to some websites. And also, they can improve Google's predictions of which websites a user wants to use to go deeper, which can improve Search performance for some sites with original insight and data.
Google announced that users can now connect external apps directly to Search from AI Mode (US only). The initial connected apps include Instacart, Canva, and YouTube Music. This allows AI Mode to take actions and draw upon external app capabilities directly within the search experience, continuing the move toward agentic search workflows.
Universal Commerce Protocol (UCP) spotted for more brands in organic search results. Originally spotted primarily on Wayfair listings in the US, Brodie Clark and others observed UCP expanding across more retail and ecommerce brand results.
Google released the June 2026 Spam Update. The rollout was fast, completing in just two days on June 26. As with typical spam updates, it targeted sites violating Google's spam policies across all languages.
May 21, 2026: New core update went live. It will take up to 2 weeks to complete. Google linked to their standard guidance on core updates. Although nothing has changed in this document, it is worth noting that just a few days ago they published new guidance on ranking in the AI features in Search which includes recommendations to provide a unique point of view, focus on non-commodity content, avoid scaled content, organize content in a way that helps your readers and add high quality images and video.
May 19, 2026: Gemini 3.5 Flash is now the default model in AI Mode for everyone globally. Also, the Search Box has changed to now provide AI powered suggestions and allowing you to search across modalities using text, images, files, videos or Chrome tabs as inputs. And, importantly, AI Overviews are now showing the ability to ask a followup question, which then takes you to AI Mode. This was announced back in January and some are saying it is not new. It just started appearing for me on May 19, however. Prior to this there was a button to encourage the user to explore more in AI Mode. Now there is a box to ask a followup question.
May 15, 2026: Google made changes to their spam policies to indicate it is considered spam to attempt to manipulate generative AI responses in Google Search. No spam update was mentioned at this time. However, I have heard rumblings amongst black hat SEOs that they are seeing significant ranking changes.
