On May 19th Sundar Pichai took the Google I/O stage and redesigned search for the first time in more than 25 years. Here is what changed, what it means for your website, and what you should be doing this very week.
I have been in SEO since 2009 and I have never seen anything like this
I lived through Penguin, Panda, BERT, Helpful Content and AI Overviews. Every major Google change rewrites the rules of the game. What just happened at Google I/O 2026 is not a rule change. It is a game change.
Pichai said it in plain words: “the agentic era”. And it is not marketing.
Gemini 3.5 Flash is now the default model in AI Mode. A billion people a month are already using it to search. The Google box is no longer a box, it is a conversational entry point with multimodality built in. And AI agents are starting to do tasks for us: monitoring websites, comparing prices, calling restaurants to book a table.
If you run digital marketing or own a site that lives off organic traffic, this affects you. Not next year. Now.
I break it down into the 8 points where I see the biggest opportunities and risks.
1. The classic search box stops making sense
What changed. Google redesigned the search box so it works as an entry point for long prompts. It now expands dynamically, accepts multiple formats at once (text, image, video, Chrome tabs), and suggests more complete reformulations before you press enter.
How it affects you. The entire logic of “I optimize for the keyword SEO agency Barcelona” falls short. Users no longer type two or three words. They type long questions, with context, with attached files.
This breaks the classic keyword research model. Someone who used to search “web design pricing” can now type “I am launching an online cosmetics store in Catalonia with an 8,000 euro budget, what kind of website do I need and how much should I pay”. The second one is what Gemini sees and processes.
What to do. Reorient your content towards long, specific queries. Cover the context that surrounds a decision, not just the keyword itself. If you sell a service, do not write about the service: write about the client situation that comes before hiring it.
2. Gemini 3.5 Flash as the global standard
What changed. Gemini 3.5 Flash becomes the default model for AI answers in search. Faster than its predecessors, cheaper to operate, and with improved benchmarks on agentic tasks. Pichai used the presentation to show the math: a company processing a trillion tokens a day saves more than a billion dollars a year by switching to Flash from competing models.
How it affects you. This proves AI generated answers are no longer a side experiment next to the classic blue results. They are the core product. Google is betting everything on this.
What to do. Assume your strategy has to feed this model. If your content does not show up in AI Mode answers, you are invisible to a growing share of qualified traffic. This is what we call GEO (Generative Engine Optimization) at SEOCOM, and what we have been working on since before Google gave it an official name.
3. Conversational searches with continuous context
What changed. The user no longer starts from scratch after each search. Follow-up questions are possible while keeping the previous context. The AI remembers what came before and refines its answer.
How it affects you. SEO stops being linear. It used to be query, result, click. Now you can be irrelevant in the user’s first question and decisive in the third. Or the other way around: rank top in the first one and lose the opportunity in the next.
This changes how content gets structured. “Frequently asked questions” stops being a section at the end of the post. It becomes the backbone.
What to do. Design your content around supporting questions. After reading the general answer, what will the user wonder next? What objection will they have? What will they need to compare? Cover those second and third questions. The AI will look them up the same way it looks up the primary ones.
4. Enter the Search Agents
What changed. Google introduces agents that work 24/7 in the background on the user’s behalf. They notify the user when something of interest happens: a pair of sneakers drops, a flight price falls, an apartment matching their criteria hits the market.
This is how they work: the user describes what they care about in a long sentence, the agent monitors the web continuously, then notifies with a synthesized summary and a way to act. The feature lands this summer for Google AI Pro and Ultra subscribers.
How it affects you. If the user delegates their searches to an agent, that agent becomes your new user. It is not a person evaluating with human judgement. It is a system filtering content by structure, authority, freshness and technical clarity.
If your value proposition is ambiguous, if your information is poorly marked up with schema, if your prices are unclear, if your last update was two years ago, the agent will never recommend you. End of story.
What to do. Impeccable structure: schema.org well implemented, complete structured data, clear information hierarchy. Demonstrable authority: links, mentions, real cases. Constant updates: content reviewed by date, dates visible. If the agent cannot trust you, it will not show you to the human.
5. Agentic bookings and local SEO
What changed. Google extends agentic bookings to local services. The agent can compare availability across several businesses, make the reservation for you, even call the venue by phone if they do not have an online system.
Pichai gave a concrete example in the keynote: booking a karaoke spot for a friend’s birthday. The agent looks for availability, compares options by user preferences, and books.
How it affects you. For local SEO, having an updated Google Business Profile is no longer enough. Appearing in the Local Pack is no longer enough. You have to be readable by an AI that will execute a concrete action on the client’s behalf.
What to do. Clear, up-to-date hours, no fuzzy “we open around 9”. Services well defined with prices when you can give them. Real-time availability if your business allows it. Consistent reviews, not contradictory. Contact information a machine can process without parsing free text.
If you handle local SEO for clients, this is a new scenario. My recommendation: audit the 10 main businesses you handle and ask “can an agent book here without human intervention?”. If the answer is no, you have work to do.
6. Generative interfaces (Google Antigravity)
What changed. For complex queries, Google can generate mini-apps, dashboards, tables or custom widgets directly inside search. It does not send you to an external site. It builds the result inside Google.
If you search “compare the 5 best health insurance options for freelancers in 2026”, Google can synthesize a comparison table with data from several sources. The user gets what they need without clicking on any site.
How it affects you. Zero-click risk goes up. Your content becomes raw material for Google to build its answer. Traffic to your site can drop while your information keeps being used. The traffic-based monetization model weakens.
This was already happening with AI Overviews. Antigravity takes it to the extreme.
What to do. Rethink how your brand monetizes. If you depend solely on organic traffic to sell, you are going to suffer. Move to an authority and qualified conversion model. Offer experiences and services that a table cannot synthesize: consulting, proprietary tools, communities, interactive content.
If you sell products: brand and differentiation. If you sell services: direct relationship and proof of use cases. AI does not replicate personal trust.
7. Personal Intelligence: the average position is dead
What changed. Google connects search to the user’s personal apps (Gmail, Google Photos, Calendar, Drive). The system now answers with their personal context in mind. Personal Intelligence rolls out to 200 countries.
How it affects you. The universal answer disappears. Two people can run the exact same query and see completely different results based on their context. Their emails, their calendars, their travel history, their previous purchases all weigh in.
The “average position” metric we have been using for years in Search Console loses meaning. Average position for whom? For what context?
What to do. Accept that abstract ranking stops being the queen metric. Focus on qualified traffic and real conversion. Measure impressions by intent, not by keyword. Measure post-click engagement. Measure qualified leads, not sessions.
And if you report SEO to leadership, get ready for different conversations. The KPIs are changing.
8. Agentic commerce for e-commerce
What changed. Google announces new protocols for universal carts: the AI helps the user find the best prices, compare specs, manage cross-merchant carts and make secure payments. The user no longer enters a specific store. They enter a purchase process mediated by an AI.
How it affects you. For e-commerce, this is massive. You no longer compete only to show up in product searches. You compete to be picked by an AI inside an automated purchase process. The AI evaluates price, availability, shipping policy, return policy, reviews, compatibility with what the user already owns.
A store with great SEO but an unclear return policy can lose sales to one with worse SEO but better data structure.
What to do. Perfect data markup. Complete Product schema: price, availability, attributes, GTIN, MPN, brand. Clear, well structured shipping policy. Return policy in structured data. Authentic, visible reviews. Compatibility info if you sell technical products.
If you have product pages in your CMS and you have not reviewed them in the past year: you have work to do.
What I would do this week if I were you
I summarize the concrete actions in order of priority. This is what we are doing for SEOCOM clients.
1. Audit your schema.org. Selling products: complete Product schema. Local business: LocalBusiness with every field filled in. Publishing content: Article + Author + Organization properly defined. Without correct schema, agents will not read you.
2. Rewrite your headlines around questions, not keywords. If your H1 is “SEO Services in Barcelona”, move it to something more conversational without dropping the classic SEO. People no longer search “SEO services Barcelona”. They search “which SEO agency would you recommend in Barcelona for a cosmetics e-commerce”.
3. Create content for follow-up questions. After your main post on a topic, add sections covering the doubts a user will have after reading it. Anticipate the conversation.
4. Review your Google Business Profile and reviews. For local SEO, this moves from “we should” to “we have to”. Hours, prices, specific services. No ambiguity.
5. Implement or review your GEO strategy. Showing up in answers from Gemini, ChatGPT and Perplexity is no longer optional. It is the channel where more and more qualified traffic is coming from. At SEOCOM we treat it as a specific sub-discipline within modern SEO.
6. Rethink your KPIs. If you keep reporting average position to leadership, you will look bad in six months. Move to qualified traffic, conversions by intent, share of voice inside AI answers.
7. Subscribe to AI Pro or Ultra. Yes, it sounds self-interested, but do it to test how Search Agents behave from the user’s side. See whether they recommend you (or not) when an agent is in the loop. It is the best training you will get this year.
What we still do not know
I am being honest: there are things that were announced but where the picture is not fully clear yet.
We do not know how Google plans to balance zero-click with keeping the editorial ecosystem alive. If websites stop receiving traffic, they stop producing content, and the AI runs out of raw material. It is a fragile balance.
We do not know how much weight llms.txt files will carry. Lizzi Sassman left it ambiguous from Google: useful if you have agents using your site, but nothing you need to rush yet. I would still implement it preventively if you have the resources.
We do not know how personalized search will really impact comparable metrics across companies. The SEO industry will have to reinvent part of its reporting dashboard.
What I do know is that whoever reacts this week will have an edge over whoever waits until November.

Full Google I/O 2026 keynote (official Google channel)
Official Google sources with the details of each announcement:
- Welcome to the Gemini-powered agentic era, the article by Sundar Pichai
- A new era for AI in Search, what specifically changes in Google Search

Want to adapt your strategy to this new scenario?
At SEOCOM we have been working on GEO since 2024. We know how to show up in answers from Gemini, ChatGPT and Perplexity because we already do it for clients. After Google I/O 2026, this stops being an early advantage and becomes a basic requirement.
Two entry points depending on what you need: understand the discipline as a whole, or start right away with a diagnosis of your site.
