For more than 25 years, search has worked in a fairly familiar way. Type in a query, scroll through a list of links and decide where to click.
At Google I/O 2026, Google unveiled what many are calling the biggest shift to Search in more than two decades, introducing a new AI-powered search experience designed to move users beyond traditional lists of links and into more conversational, predictive and interactive journeys powered by Gemini.
The changes announced have the potential to reshape how brands are discovered, how visibility is measured and what it takes to stay competitive in search moving forward.
Here are some of the biggest announcements and what they could mean for search.
Key takeaways from Google I/O 2026:
One of the most talked-about moments from I/O came from Google’s overhaul of Search itself.
Google introduced what many publications are calling the "biggest change to Search in more than 25 years". Instead of users simply typing keywords and browsing blue links, Google is moving toward conversational AI-led experiences powered by Gemini.
TechCrunch summed it up pretty bluntly with the headline:
“Google Search as you know it is over.”
That might sound dramatic, but the direction of travel is obvious.
Search is becoming:
Instead of giving users a list of links and asking them to do the work, Google increasingly wants to provide the answer directly in one interface without the user leaving the platform.
Google is continuing to heavily push AI Overviews and its new AI Mode experience, signalling a major shift in how people interact with Search. Instead of simply typing in keywords and clicking through multiple websites, users are increasingly being given AI-generated summaries, recommendations and follow-up answers directly within Google itself.
AI Overviews are already being used by more than 2.5 billion users every month while its conversational search mode is now topping 1 billion monthly users- showing just how quickly AI-powered search behaviour is becoming mainstream.
For marketers, this means visibility is no longer just about ranking first in traditional search results. It’s increasingly about becoming a trusted source that Google’s AI systems choose to reference and surface within these new experiences.
Google also gave an early look at how this could eventually change the design of Search itself through its new agentic development platform, Google Antigravity, combined with Gemini.
Instead of search results simply showing a list of blue links like it currently does, future search experiences could become far more interactive and dynamic, almost behaving more like live web applications that users can engage with directly inside Search.
One of the biggest themes from Google I/O 2026 was “agentic AI.”
In simple terms, AI is moving from being something that responds to prompts to something that actively helps users complete tasks.
Google announced new Gemini-powered AI agents capable of:
Known as “information agents” by Google, they are designed to proactively research and gather information for users behind the scenes. These experiences are expected to begin rolling out to Google AI Pro and Ultra subscribers this summer as part of Google’s wider AI search push.
Another key change is the rise of conversational search journeys. Users can now ask follow-up questions directly inside search experiences without starting over.
Instead of:
Users are now moving through evolving conversations with AI. For example:
A user might search: “Best CRM for growing retail businesses”
Then follow up with:
All without leaving Google.
That means content ecosystems, not isolated landing pages. The businesses that perform well are likely to be the ones answering entire journeys, not just individual searches.
One particularly interesting update was Google expanding AI search experiences to include more community-based content, including Reddit and forums.
This lines up with a wider trend we’ve been seeing for a while - people increasingly trust human experiences over polished corporate messaging.
Google knows this. That’s why:
For brands, this reinforces the importance of:
Simply rewriting generic SEO blogs with AI isn’t going to cut it anymore. Google is clearly prioritising content with genuine expertise, authority and real-world perspective.
There’s another side to all of this too. AI search may reduce website traffic.
Research data published this year found AI Overviews can reduce traffic to informational websites by around 15%.
Other studies also suggest users increasingly get answers directly inside search rather than clicking through to websites.
This means marketers need to rethink what success looks like.
In the future, visibility may not just mean:
It may also mean:
This is exactly why AEO (Answer Engine Optimisation) and GEO (Generative Engine Optimisation) strategies are becoming more important.
Although newer terms like AEO and GEO are becoming more common across the industry, Google’s view is that this is still SEO at its core. The difference is that brands now need to think beyond traditional rankings and optimise for how they appear across AI-driven search experiences, conversational journeys and generated answers.
For marketing teams, the opportunity now is understanding how to stay visible, trusted and discoverable.That means evolving beyond traditional SEO tactics to factor in AI-driven discovery, conversational search and multimodal experiences.
At STM AGENCY, we’re already helping brands navigate these changes through data-informed search strategies, AI visibility planning and performance-led digital campaigns designed for where search is heading next.
As search continues to evolve, businesses need more than traditional SEO reporting and rankings alone. They need a clearer understanding of how their brand is appearing across AI-driven search experiences, where opportunities are emerging and how consumer behaviour is shifting in real time.
That’s exactly where having the right strategy, insight and specialist support becomes critical.
