If there’s one thing Google excels at, it’s keeping us on our toes – and this year’s I/O delivered a massive shake-up. 

From rolling out Gemini 3.5 Flash and autonomous Search Agents, to transforming Maps and YouTube into deeply conversational experiences, the search landscape as we know it has been entirely redrawn. But what does this actually mean for businesses and everyday users?

Until now, the web operated on a simple exchange: publishers created valuable content, and Google rewarded them with traffic that fuelled leads and revenue. It was a win-win system that allowed SEO to thrive on keyword-based optimisation.

It was simple, measurable, repeatable and above all, deterministic.

Today, that model is flipping. AI Search is compressing the digital ecosystem into a single, synthesised answer layer. The AI model controls it, and honestly, it doesn’t like to share much of the credit with publishers, let alone visibility over your brand performance in this new ecosystem. 

Driven by AI Overviews,  AI Mode, ChatGPT and Perplexity, we are already living through a “great decoupling” of search visibility and traffic and as the adoption of AI search is the fastest technological rollout in history, we can only expect this to grow.

The data proves it: Google is now processing quadrillions of tokens every single month. Users aren’t just testing AI, they are adopting it at scale. We are moving toward a future of total search automation, where Search is no longer a moment in time. It is a continuous, automated service and the businesses that succeed will be the ones that evolve with it.

Looking at the updates brought by Google

Gemini Flash 3.5 

With this latest update, Gemini Flash 3.5 is officially rolling out to power the core Search experience and it’s now baked directly into the core of Search. The traditional ten blue links will still be there and visible alongside AI Overviews, but they will likely fade out in the future.

AI Overviews meet AI Mode

The era of “testing” is over. What was once an experiment is now our reality. In the UK, the transition from AI Overviews (AIO) directly into a full-screen AI Mode is officially live across both Mobile and Desktop. 

For informational queries, the friction has vanished. We are no longer looking at a static summary at the top of a page; we are looking at the front door to a deep, fluid dialogue. Google has merged the initial overview and the conversational “AI Mode” into one continuous experience. While some commercial and shopping-related queries still retain traditional elements, the direction of travel is clear.

As the conversation gets deeper, the AI’s answers evolve with it – shifting from a surface-level summary to a granular, personalised deep dive without the user ever needing to click on a traditional link.

The new intelligent search box 

For decades, the Google search bar has been a simple, static text field. Not anymore. While we’ve been able to use tools like Google Lens for visual searches in the past, Google is now tearing down the walls between these fragmented features and uniting them into one seamless interface. 

Moving forward, you are no longer limited to typing out your thoughts. You can now search using any combination of text, images, video, and files. 

Information Agents 

These agents transform search from a reactive tool into a proactive, 24/7 tracker. Instead of you repeatedly checking the web, your personal agent continuously scans blogs, news sites, social media, and real-time data feeds (like finance, shopping, and sports) to monitor changes specific to your needs.

It doesn’t just send you spammy alerts (‘Google Alerts’); it delivers an intelligent, synthesised update designed for immediate action.

  • For users: imagine brain-dumping a hyper-specific list of flat requirements, and having your agent continuously scan the market to notify you only when a listing fits your exact criteria. Or, tracking your favourite travel destinations and skincare brands and getting notified when there is a sale or new product launch?
  • For Businesses: this is a competitive game-changer. Instead of manual market research, you can deploy agents to track competitor movements, industry trends, and pricing shifts across the web in real time.

It now makes sense that Google patented a technology that detects when there is no satisfactory answer for a query and delivers an answer once it becomes available.  

Gemini Spark: Your Autonomous Executive Assistant

If Information Agents are your researchers, Gemini Spark is your executive assistant.

It is an autonomous agent designed to sit securely inside your private Google ecosystem – meaning it has direct, conversational access to your Gmail, Calendar, Docs, and Drive. Spark bridges the massive gap between finding information and executing tasks based on that information.

Ask Google Maps and YouTube 

Google Maps and YouTube are also getting an upgrade. You didn’t think Google would leave them out, did you? With the latest updates, we will be able to search within Google Maps and YouTube content. 

Instead of searching for keywords like “coffee near me” and digging through hundreds of star ratings, users can now have a natural conversation with their map. For example, you can now query, “My phone is dying – where can I charge it quickly without waiting in a long line for coffee?”  

Universal Cart 

The Universal Cart is a ubiquitous layer that follows the user across the entire Google ecosystem. Whether they are browsing Search, watching a review on YouTube, or brainstorming ideas within a Gemini chat, they can add products to their cart instantly – without ever leaving the page.

The moment a product enters the Universal Cart, the AI starts working. It automatically hunts for the best deals, monitors price drops, tracks price history, and pings the user the second an out-of-stock item returns.

Rolling out in the US this summer, the Universal Cart transforms Google from a discovery engine into a full-scale, automated procurement assistant. For brands, the conversion funnel just got shorter; for users, the hunt for the best price is now completely hands-free.

Impact on businesses 

Redefine what “success” looks like as traffic is and it will continue to go down.

You need to break away from reporting on traffic. If your website exists solely to answer basic questions or provide generic informational content, AI Overviews and AI Mode will eat your lunch. Google’s goal is to answer the user’s query instantly, without a click. 

The Great Decoupling means traffic will drop, but the traffic you do get will be highly qualified, bottom-of-the-funnel users who are ready to convert. Shift your KPIs away from sessions and pageviews, and focus entirely on business impact: leads generated, conversion rates, and revenue.

Attribution and measurement are going to get messy 

When a background Information Agent reads your blog, synthesizes the data, and delivers it to a user via voice while they are driving, how do you track that click? You don’t. Traditional, click-based attribution models are fundamentally breaking.

Own the specific long-tail

The future is conversational and specific. Users aren’t searching “best CRM”; they are asking Gemini, “What is the best CRM for a mid-sized B2B agency that integrates natively with Slack and has automated reporting?” Your content, video scripts, and product pages must answer deeply specific, multi-layered problems.

Brand Sentiment is the new ‘ranking factor’

Gemini doesn’t just read your website; it reads the entire internet. If a user asks an AI Agent to recommend a digital marketing agency, the AI will scrape Reddit, PR articles, forums, and third-party reviews to gauge public consensus. Digital PR and brand reputation are no longer just “nice-to-haves” – they are critical inputs that train the AI to recommend you.

Know who you are and make sure AI knows it too

I’ve written more extensively about Brand and AI Search before but if I were to summarise it here:

AI models don’t just index your site; they build a comprehensive understanding of your brand by cross-referencing everything said about you across the entire web. If a user asks Gemini for recommendations, the AI will pull from Reddit, forums, PR articles, and third-party reviews to gauge public consensus.

To surface in AI Overviews and personalised recommendations, you must know exactly who you are, what you specialise in, and loudly communicate that clear, consistent narrative not just on your own website, but across every third-party platform where your audience and AI search is listening.
