I don’t say this lightly: what Google announced this week at Google I/O is the biggest change to Search since the search box was invented.
Not an algorithm update, not a new SERP feature, but a full-blown platform shift.
So let me break down what’s actually happened, and what you need to do about it.
What’s happened?
AI Mode has passed one billion monthly users, with queries more than doubling every quarter. Gemini 2.5 Flash is now the default model powering Search globally. And the Search box itself has been fundamentally rebuilt – it now anticipates intent before you finish typing, accepts multimodal inputs (text, image, voice, combined), and flows into full back-and-forth AI conversations.
That billion-user figure isn’t a statistic to file away in a quarterly deck – it should drive action. It means AI-powered search is already mainstream and the question is no longer whether your customers are using AI Mode, because they absolutely are! The question is whether your brand is showing up in it.
What’s actually changed (and why it’s not business as usual)
For decades, Google Search operated on a simple transaction: a user types a query, Google serves ten blue links, the user clicks. Brands optimised for that moment. Rankings, click-through rates, meta descriptions. That was the game.
That game has changed.
Search is now conversational. A user can move seamlessly from an AI Overview straight into a multi-turn dialogue with AI Mode, with full context carried across the session. They don’t click through to your site to start the conversation. The conversation starts without you. And if your brand isn’t present in that opening AI answer, you’re invisible for everything that follows.
Search is also now agentic. Google is launching information agents that operate 24/7, scanning the web and real-time data to surface what a user needs at exactly the right moment. Your brand doesn’t just need to rank. It needs to be the answer an agent selects, validates and serves.
And search is now a transaction layer. Agentic booking is native to search, pulling together pricing and availability with direct links to complete a purchase. If your structured data isn’t tight and your availability isn’t live, you’re handing that conversion directly to a competitor.
The four things you need to act on now
I’ve been working in search for over a decade. I’ve seen Google updates that moved rankings; Panda, Penguin, the mobile-first index. This is different. This isn’t a change you adapt your existing strategy to. This is a rebuild and you need to build a new strategy in order to succeed.
Here’s what your brand needs to prioritise:
1. Answer conversations, not just queries
Traditional SEO optimised for a single intent signal at a specific moment. AI Mode operates across a session. That means your content needs to be the kind that earns its place in an AI Overview and then holds up under follow-up questions. Think depth, authority, and specificity. If you’re writing thin content that answers one narrow query and stops, you’re building for a search paradigm that’s already behind you.
2. Prepare your brand for search agents
Google’s information agents don’t just crawl for keywords. They evaluate entities, authority signals, structured data and real-time relevance. Your brand needs clear, consistent entity definitions across your site and across the web. Who you are, what you do, what you stand for. If Google’s agents can’t confidently categorise your brand, they won’t confidently recommend it.
3. Get your data agent-ready
Agentic booking changes the commercial stakes entirely. An AI agent that can complete a transaction on a user’s behalf will select the option with the clearest, most reliable data. That means structured data done properly: schema markup, live pricing feeds, real-time availability. It means your technical foundations need to be solid, not on the to-do list. If your product or booking data isn’t machine-readable, you’re simply not in the running.
4. Stop betting everything on static content
One of the most striking announcements from Google I/O was that Search can now build custom dashboards and visual tools in real time, tailored to an individual user’s specific question. Think about what that means for the blog post you spent three weeks producing. A static piece of content is competing against a dynamically generated, personalised experience built on the fly for that exact user. That is not a fair fight on pure content alone.
The brands that will win this aren’t necessarily the ones with the most content. They’re the ones with the best data, the clearest entity authority, and the technical infrastructure that AI systems can actually use.
What this means for your investment in search
I know what some of you are thinking. We’ve heard “search is changing” a lot over the years. And yes, we’ve adapted each time. But here’s what I want to be direct about: the pace and scale of this shift is different and you need to take note now.
Brands that are investing now in AI visibility, entity authority and structured data are building a compounding advantage. Every week that passes where your site isn’t optimised for how AI agents evaluate and serve content is a week your competitors who are investing in this can pull further ahead.
The good news? This isn’t starting from scratch. If you’ve built strong SEO foundations over the years, you have something to work with. But the work now is different. It’s about entity clarity, technical precision, content that earns AI citations, and commercial data infrastructure that agents can act on.This is exactly what we’re helping our clients navigate. If you want to understand where your brand stands against the new AI search landscape, and what to prioritise, let’s talk.
