The rollout may take up to two weeks. Google hasn\u2019t published a companion blog post or shared goals for the update.<\/p> <p><iframe class=\"sej-iframe-auto-height\" id=\"in-content-iframe\" scrolling=\"no\" src=\"https:\/\/www.searchenginejournal.com\/wp-json\/sscats\/v2\/tk\/Middle_Post_Text\"><\/iframe><\/p> <h3>Why This Matters<\/h3> <p>The timing puts this update in the middle of Google I\/O week. Ranking movement over the next two weeks will overlap with other changes Google announced, which could make it harder to isolate what caused any shifts you see in Search Console.<\/p> <p>Your baseline should be the weeks before May 21, compared against performance after the rollout finishes. Wait at least one full week after completion before reviewing data.<\/p> <h3>What SEO Professionals Are Saying<\/h3> <p>Marie Haynes, founder of Marie Haynes Consulting Inc., connected the timing to I\/O:<\/p> <blockquote> <p>\u201cMakes sense seeing as Gemini 3.5 Flash is now powering the AI features of Search.\u201d<\/p> <\/blockquote> <p>Harpreet Singh Chatha, SEO &amp; AI Search Consultant, suggested this update could be targeting websites that are over-optimizing for AI citations:<\/p> <blockquote> <p>\u201cCalling it now. If you\u2019ve been doing dumb [things] to show up in AI answers this one\u2019s coming for you.\u201d<\/p> <\/blockquote> <p><em>Read our full coverage: Google Begins Rolling Out May 2026 Core Update<\/em><\/p> <h2>Google Redesigns Search Box, Upgrades AI Mode &amp; Previews Search Agents At I\/O<\/h2> <p>Google announced Gemini 3.5 Flash as the new default model in AI Mode, redesigned the Search box with AI capabilities, and previewed information agents coming this summer.<\/p> <p><strong>Key facts:<\/strong> Google described the redesigned Search box as its biggest upgrade in over 25 years. It expands dynamically, supports multimodal inputs like images and files, and provides AI-powered suggestions beyond autocomplete. Information agents will monitor the web and deliver updates. New features include agentic booking, generative UI, and Personal Intelligence expansion to nearly 200 countries.<\/p> <h3>Why This Matters<\/h3> <p>The Search box redesign prompts users to describe needs in longer, conversational queries. Paired with Gemini 3.5 Flash in AI Mode, responses mostly come from AI rather than traditional pages.<\/p> <p>Information agents continuously search and synthesize updates, raising questions about whether your content is cited or overlooked in those summaries.<\/p> <h3>What SEO Professionals Are Saying<\/h3> <p>Jake Ward, SEO\/content entrepreneur building Mentions, wrote:<\/p> <blockquote> <p>\u201cMy feed is full of \u2018SEO is dead\u2019 posts today. But none of this should be a surprise. Every platform we use is moving towards AI-first, agentic, proactive experiences like this. And clicks were already dying. We\u2019ve watched CTR decline for 2-3 years straight now. However, search is very much alive, just different. We\u2019re moving further into a world of visibility &gt; clicks.\u201d<\/p> <\/blockquote> <p><em>Read our full coverage: Google\u2019s New Search Box Hands Queries To AI Agents, I\/O Reveals<\/em><\/p> <h2>Google Releases First AI Mode Usage Data After One Year<\/h2> <p>Google published a report on how people use AI Mode in the U.S., drawing on internal Search data and Google Trends one year after launch.<\/p> <p><strong>Key facts:<\/strong> AI Mode has over 1 billion monthly users, with queries doubling each quarter. Searches are thrice as long as traditional ones, and follow-up queries increase 40% monthly in the U.S. Over 16% of searches are multimodal, using voice, images, or video. Planning queries grow at 80% the rate of overall usage. Trends data isn\u2019t publicly available.<\/p> <h3>Why This Matters<\/h3> <p>The key insight is the behavioral data, not milestone numbers. Users write longer queries, follow up more, and use multiple input types, changing content and how it surfaces.<\/p> <p>Pages with short keywords may not match AI Mode\u2019s conversational patterns. Growth in planning queries is significant; when users ask AI Mode to compare products, evaluate services, or research, that content has commercial value, even without clicks.<\/p> <p>Google\u2019s report is based on internal, unverifiable data, and AI Mode search trends aren\u2019t available publicly.<\/p> <h3>What SEO Professionals Are Saying<\/h3> <p>Jeffrey Cohen, chief business development officer at Skai, wrote:<\/p> <blockquote> <p>\u201cShoppers aren\u2019t typing \u2018running shoes.\u2019 They\u2019re asking \u2018what are the best running shoes for a wide foot that I can wear for a half marathon training on pavement under $150.\u2019 That\u2019s not a keyword. That\u2019s a brief. Planning queries grew 80% faster than AI Mode overall in the last 6 months. That means shoppers are using AI as a research partner long before they hit buy. The brand that shows up during research owns the consideration phase. The transition from keyword to conversation has been talked about for years. The data says it\u2019s already here.\u201d<\/p> <\/blockquote> <p>Alisa Scharf, CAIO at Seer, pointed to the measurement gap:<\/p> <blockquote> <p>\u201cFor those of us who weren\u2019t yet investing in tracking visibility in AI Mode, we\u2019ve gotta bug our product or procurement teams to get more tracking established. Can\u2019t optimize what you can\u2019t measure. If anyone from Google follows me \u2014 It\u2019s really pretty wild that none of these metrics are available for free in Google Webmaster tools. I so rarely shake my fist in the general direction of Palo Alto, but this is becoming obscene. Big props to the team at Bing who\u2019s investing in a real control center of information with their Webmaster Tools.\u201d<\/p> <\/blockquote> <p><em>Read our full coverage: Google Reveals First AI Mode Usage Numbers After One Year<\/em><\/p> <h2>Google\u2019s Llms.txt Guidance Splits Between Search &amp; Lighthouse<\/h2> <p>Google\u2019s Search team and its Lighthouse team are giving different guidance on llms.txt. Meanwhile, Mueller clarified where markdown pages for LLMs do and don\u2019t help.<\/p> <p><strong>Key facts:<\/strong> Google\u2019s AI guide states llms.txt isn\u2019t needed for AI Search. Lighthouse 13.3 checks for llms.txt by default, flagging sites with errors. Mueller said markdown pages are useful for documentation but not for most websites. He differentiated discovery (search visibility) from on-page tasks, advising sites to focus on being found.<\/p> <h3>Why This Matters<\/h3> <p>The answer depends on your traffic. If agentic tools visit and complete tasks, markdown versions of your docs may help those tools. If you\u2019re planning for the future, Mueller recommends prioritizing current needs first, saying, \u201cPrioritize needs before dreams.\u201d<\/p> <p>The conflict between the Search and Lighthouse teams exists, and Google hasn\u2019t resolved it. Search Central offers guidance for Search visibility, while Lighthouse assesses agentic browsing readiness, not ranking or AI Mode eligibility.<\/p> <h3>What SEO Professionals Are Saying<\/h3> <p>Chris Long, co-founder of Nectiv, wrote:<\/p> <blockquote> <p>\u201cChrome just released documentation on their new Agentic Browsing audits. Somewhat buried in there, they reference how the audit will check for the LLMs.txt file. It mentions how it \u2018checks for the presence of a machine-readable summary at the domain root.\u2019 This is less than a week after their documentation talking about how SEOs don\u2019t need to worry about additional files + markup. I\u2019m starting to turn around on the LLMs.txt a bit. Some seriously smart people including Crystal Carter, John-Henry Scherck, Joost de Valk are turning me around on it a bit. It also seems very clear that Google doesn\u2019t want us to test this stuff. To just keep doing SEO as we\u2019ve normally done it without looking behind the scenes and waiting for their guidance.\u201d<\/p> <\/blockquote> <p><em>Read our full coverage: Mueller Explains Why Google Uses Markdown On Dev Docs | Google\u2019s llms.txt Guidance Depends On Which Product You Ask<\/em><\/p> <h2>Theme Of The Week: The Quiet Rebuild<\/h2> <p>Google is rebuilding Search around AI while telling everyone the fundamentals still apply.<\/p> <p>The optimization guide published last week says AEO and GEO are \u201cstill SEO.\u201d Mueller says to focus on current needs. The core update rollout looks like any other. But the same week, Google announced what it called the biggest upgrade to the Search box in over 25 years, reported that AI Mode has surpassed 1 billion monthly users, announced always-on information agents, and released data showing user behavior is already shifting toward longer, multimodal, follow-up-heavy queries.<\/p> <p>The gap between Google\u2019s public guidance and its product roadmap keeps widening.
