Google I/O 2026: What It Actually Means for Your SEO

The number Google really wants you to notice

Let me throw one number at you, because it’s the one everything else hangs off. AI Mode, which is Google’s chatty AI answer thing that now sits right at the top of your search results whether you asked for it or not, just passed a billion monthly users. A billion. And the queries going into it have doubled every single quarter since it launched, which is the kind of growth that makes a marketer either very excited or slightly nauseous, depending on the day.

So no, people aren’t searching less. They’re just searching differently, which I appreciate is the sort of profound insight you could have lived without, but bear with me, because the next bit is where it gets real for you.

The average AI Mode search is about three times longer than a normal Google search. People aren’t typing “kitchen showroom Surrey” anymore. They’re typing whole sentences, the way they’d actually ask a mate, something like “independent kitchen showroom near Guildford that does German cabinetry with a five-week lead time.” Which is brilliant news, honestly, because that’s a customer telling you exactly what they want. As long as your website is set up to answer them.

And if it’s not? Well. We’ll get to that.

So what actually changed?

Six things, fast.

1. AI Mode and AI Overviews are now one thing

Right, so these two used to be separate things. AI Overviews was the little AI summary that popped up at the top of the page, and AI Mode was a separate thing you had to deliberately click into. Google’s now sewn them together into one big experience, so your customer asks a question, gets a summary, asks a follow-up, and before they know it they’re having a full conversation with Google without ever once clicking through to an actual website. Yours included.

You know what that does? It quietly kills your click-through rate. On searches where AI Overviews show up, the top organic result has slid from around 27% of the clicks to as low as 11% in some of the recent third-party studies I’ve seen. And roughly 58.5% of searches in the US now end with no click at all. None. People are getting their answer and getting on with their day.

Now, if that’s just ruined your morning, hang on, because there’s good news. The pages Google actually quotes in those AI Overviews are still, underneath it all, pages with proper SEO done well. Clear headings. FAQ sections. Named places, named products, named industries, the specific stuff. So the job hasn’t really changed, it’s just doubled. Ranking on its own isn’t enough anymore. You also have to be the source the AI trusts enough to quote.

(And yes, “be the source the AI trusts enough to quote” is absolutely going to be on some bloke’s keynote slide next year. I apologise in advance.)

2. Google’s search box now eats anything

Now this was the bit I actually sat up for. Google reckons it’s the biggest rethink of the search box in over 25 years, and for once, that wasn’t just marketing speak from a man in a gilet. You can now drop in pretty much anything: text, a photo, a PDF, a video, even the tabs you’ve got open in Chrome, and Search will happily read the whole lot at once and work out what you’re on about.

What does that actually look like for a normal human? Someone spots a tap they like in a magazine, takes a photo of it, drops it into Search and asks where they can get it fitted in Sussex. A patient screenshots some aesthetic treatment they’ve been eyeing up, pops it in the box, and asks if anyone does it privately in West London. A bloke photographs the ancient boiler in his loft and asks who on earth still fits that model in Brighton.

So if you run a showroom, or a clinic, or honestly anything where people buy with their eyes, this is the one to pay attention to. Your product photos just stopped being decoration and started being search results. Your alt text just quietly became sales copy. Funny how that works.

Here’s what to do about it, and it won’t take long. Get 30+ photos onto your Google Business Profile (costs you nothing and tends to lift your GBP clicks by around 2.7x, which is frankly a daft return for an afternoon’s work), give the files proper names instead of IMG_4823, write actual alt text like a person would, and add product schema where it makes sense. Or, you know, give us a shout and we’ll have a look for you.

3. Search agents, which are sneakier than they look

Then there’s this thing Google’s calling “information agents,” which is exactly as sci-fi as it sounds. You give one a question, and then you just… walk off. It sits there in the background, 24/7, quietly watching blogs, news, social posts and Google’s own real-time data, and the second something changes, it taps you on the shoulder with a tidy little summary and an option to do something about it.

From a customer’s point of view, that’s genuinely brilliant. From a business point of view, it’s a tiny bit terrifying, and here’s why. Your potential customers can now set up a permanent watchlist for your entire category and then forget about it. Every new offer you launch, every new location you open, every fresh review you get, every time someone mentions you in the local paper: logged, filed, served up to them on a plate.

So you know what that quietly rewards? Showing up, consistently. Posting more than once in a blue moon. A steady trickle of reviews instead of nine of them in a panicked fortnight every March. Your name turning up in the local press, in trade mags, in the odd podcast. Which is, funnily enough, exactly the slow, unglamorous stuff most agencies have been quietly ignoring since about 2019, because it doesn’t tick along nicely on a dashboard.

Well. It’s the work now.

4. Generative UI (or: Search builds the page itself now)

For the trickier questions, Search has started building a custom page right there on the spot. Tables, graphs, interactive layouts, all stitched together live, based on whatever the person actually asked. No clicking around five different websites to piece it together themselves.

And for bigger, ongoing projects, it goes further. Google’s calling them “mini apps,” and the examples they used were planning a wedding and moving house, but honestly a kitchen renovation is the exact same shape of problem. Search builds the customer a little dashboard they keep coming back to, with the specs, the budgets, the suppliers, the lead times, all sat in one place. Quite handy, if you’re the one renovating. Slightly nerve-wracking, if you’re hoping to be one of those suppliers.

So where does Google pull all that from? Whichever sources are tidy enough for Gemini to actually read. Which, when you boil it down, means tables instead of waffly paragraphs, pricing explained in plain English instead of “POA,” and proper comparison pages that come right out and say “our hob versus theirs.” The dull, unsexy SEO graft — schema, internal linking, alt text, sensible headings — is now the exact same work that gets you seen by the AI. Two jobs, one bit of effort. Lovely.

5. Universal Cart, for everyone selling online

Now, if you’re a DTC brand, you sell online, or you take bookings through your website, this is your bit.

Google’s launched something called Universal Cart, which is basically a shopping basket that follows your customer around everywhere they go: Search, Gemini, YouTube, even their Gmail. And thanks to their new Universal Commerce Protocol (snappy, I know), people can now check out on Google itself for loads of brands. A couple of taps. Done. Without ever landing on your actual website.

Whether that’s brilliant or mildly horrifying depends entirely on you. If your margins are healthy and your checkout’s a faff, it’s great, because a frictionless buy usually means more people actually finish buying. If your whole pitch lives on your site, it stings a bit, because suddenly you’re fighting to be in the cart at all, and that boring old product feed you’ve never quite got round to tidying is now doing a lot of heavy lifting. Most likely it’s a bit of both, depending which way the wind’s blowing that morning.

What to do, and do soon: get the product feed clean, prices current, stock current, all the dull Merchant Center housekeeping we go on about until everyone’s eyes glaze over. If you’re an e-commerce brand, the businesses that win a spot in Universal Cart are simply the ones whose data Gemini can actually trust. Not the loudest, but the tidiest.

6. And one Google really wants you to be impressed by

There’s a new Gemini model. Faster, cleverer, better at absolutely everything, the way there always is. And look, unless you’re actually building software on top of the thing, it changes almost nothing about your Tuesday. The genuinely interesting part isn’t the engine, it’s everything they’ve bolted onto it, which is, conveniently, the five things we’ve just been through.

So… what’s the actual takeaway?

Three honest things, then I’ll let you get on with your day.

One. Don’t panic. The foundations still rank, they always have. Hand on heart, most of what we’ll be doing on our clients’ accounts between now and August is the same unglamorous graft we’d have been doing anyway: technical SEO, keeping Google Business Profiles tidy, writing content that actually has a point of view, running paid search that’s tied to real revenue, and per-location strategy where it’s needed. And if anything, that last one matters more now, not less, because every single address has to earn its own ranking. Corporate clout doesn’t carry the local branch like it used to.

Two. Brand mentions are SEO now. If your name keeps cropping up in trade publications, the local press, a podcast here and there, the odd forum thread, the AI is reading all of it and quietly forming an opinion about you. If it’s nowhere, that’s a fixable problem, and it’s exactly why we’ve started pitching digital PR to clients who genuinely wouldn’t have needed it 18 months ago.

Three. The boring stuff is the moat. The agencies that win the next 18 months won’t be the ones who’ve automated the hardest or shouted “AI-first” the loudest. They’ll be the ones quietly doing the unglamorous work properly while everyone else films themselves reacting to keynote demos. We are, for the record, very firmly in that second camp.

The bit no one’s saying

Here’s the thing to hold onto. I/O is a developer conference, and developer conferences exist to make everything sound like it’s landing tomorrow morning. It never does. This stuff rolls out slowly, in dribs and drabs, to subscribers first, probably on a wet Tuesday in 2027. Universal Cart will take a while. The information agents are starting with Pro users. Generative UI is, and I quote, “coming this summer,” which in Google-speak means whenever it’s ready.

But the direction of travel is the direction of travel, and that part’s worth taking seriously. Your customers are going to keep asking longer, more specific questions. They’ll click less and read more right there on the results page. They’ll let an agent do the boring early research for them. And they’ll trust whoever Gemini decides to trust.

The good news, and I promise this is the last time I’ll say it, is that getting ready for all of it is mostly just the work you should be doing anyway. Same work. Done faster, done more specifically, done with an actual point of view.

That’s it. That’s the lot. You can have your three hours back now.
