The search box is becoming the checkout.

A year ago, AI Mode was a tab you opted into. Today Google says it has passed a billion monthly users, runs on a new default model, and ships with the biggest redesign of the search box in 25 years. But the headline isn't the model. It's what the box now does: it doesn't just answer you — it acts for you.

01What actually changed

Google has been stacking the pieces of “agentic commerce” — search that completes tasks, not just lists links. The ones already live or rolling out: agentic booking for restaurants, events and local appointments; a Universal Cart that follows you across Search, Gemini, YouTube and Gmail; and the plumbing underneath it — a Universal Commerce Protocol for merchants and an agent payments protocol with spending guardrails. You describe what you want; the agent finds real-time matches and, increasingly, checks out.

Travel is the one everyone's watching. Google has announced hotel (and eventually flight) booking right inside AI Mode, with launch partners including Booking.com, Expedia, Marriott, IHG, Choice and Wyndham. The direction is unmistakable: more of the journey from “I'm thinking about a trip” to “it's booked” happens without you ever leaving the search box.

02The Paris hotel, revisited

We've used this example in our SEO guide for a while, and it's the cleanest way to feel the change. Booking a hotel in Paris used to mean you doing the filtering: open a few tabs, check each one — Wi-Fi? pool? near the Eiffel Tower? under budget? — and stitch the answer together yourself.

That second column isn't a prediction anymore. The planning, comparison and (for some categories) the booking already work this way. The number of places a business can be seen on the way to a sale just collapsed from ten blue links to a short, AI-curated shortlist.

03The middleman gets compressed

Here's the part that should make a few business models nervous. A lot of the web's money sits with middlemen— comparison sites, affiliate blogs, aggregators, the “best 10 X for Y” pages — whose entire job is the filtering Google is now doing natively. When the engine compares for you and books for you, the layer whose only value was comparing and routing gets thin fast.

And it doesn't stop at third parties. The shift quietly demotes your own homepage too. If an AI agent reads your prices, stock and amenities and presents them inside Google, the customer may decide — and even pay — without ever seeing your site. The visit you used to optimise for becomes a data exchange you may never witness. Shopping and booking move onto Google; your storefront becomes a feed.

04But read the fine print

This is where we'll be straight with you, because the honest read matters more than the hot take. “Google kills the middleman” is the direction, not yet the destination.

05Our two cents — what to actually do

The winners in this shift aren't the ones with the prettiest homepage. They're the ones an AI can understand, trust and quote. That's a different discipline, and it's the one we've been building toward. Concretely:

• 01
  Publish structured facts, not just prose
  Prices, availability, amenities, distances, specs — as clean, machine-readable data, not buried in a paragraph. AI can only recommend what it can parse. This is the heart of technical SEO now.
• 02
  Optimise to be selected, not clicked
  Visibility is shifting from “rank a link” to “get chosen by the AI.” That's GEO and AEO — being the source the engine cites and the option it shortlists.
• 03
  Feed the machine first-hand
  Own your product and inventory feeds and keep them honest and current, so Google reads you directly rather than an aggregator's stale copy of you. If a middleman is describing you, they're the one getting found.
• 04
  Be the brand, build the authority
  Agents lean on entities they trust — consistent identity, real reviews, citations, a tidy knowledge graph. Brand equity is becoming an SEO input, not just a marketing nicety.
• 05
  Don't depend on the layer being removed
  If your traffic rides on comparison sites or affiliates, build the direct relationship now — your own findability, your own bookings, your own list. The intermediary you rely on may be the one getting compressed.

None of this is theoretical for us. We're already readying a clinic's site for AI Mode as the default way patients find it (see the Sierra Allergy case study), and the same structured-data thinking runs through the search work in our marketplace and HSY studies. The businesses that prepare for “the engine filters for you” will be the ones it filters toward.

The search box becoming the checkout isn't the end of the open web for everyone — but it is the end of coasting on being a step in someone's journey. Be the destination, be legible to the machine, and you don't need the middleman. That's the whole game now.
