Google's new intelligent Search and 24/7 agents: what changes for your business
By Miguel Maio ·
TL;DR
- At I/O 2026 (May 19), Google reinvented the Search box - its biggest upgrade in over 25 years - and is rolling it out through summer: it expands for long questions, suggests intent (well beyond autocomplete) and accepts text, images, files and videos.
- It launched search agents: 'information agents' that work 24/7 in the background, reason across the web (blogs, news, social) and fresh data (finance, shopping, sports) and send you synthesized updates, with actions.
- AI Mode's default model is now Gemini 3.5 Flash; AI Mode has passed 1 billion monthly users, with queries more than doubling every quarter.
- What changes for you: search stops being 'ten links' and becomes conversation plus action. Optimize for intent and long questions, for freshness (agents reward it) and for being the source AI picks.
At this year's I/O, Google didn't tweak a detail of search - it changed the front door. It reinvented the Search box (its biggest upgrade in over 25 years) and launched agents that now search for you, 24 hours a day. The usual noise talked about "features"; what matters is what this does to how you're found. That's what I translate here, no hype.
What Google changed - and why now
In May, at I/O, Google announced three things that touch you: an intelligent Search box, search agents that work in the background, and Gemini 3.5 Flash as AI Mode's new engine. Why now? Because the bet is paying off: AI Mode passed a billion monthly users, with queries more than doubling every quarter since launch. When a behavior grows this fast, Google builds it a front door - and it did.
The intelligent Search box: the end of the two-word query
The new box was designed for long questions, not two keywords. It expands as you type, suggests how to phrase the question (well beyond autocomplete) and accepts text, images, files, videos and even Chrome tabs. And from an AI Overview, you slide into an AI Mode conversation without losing context. The translation for anyone doing SEO is blunt: searches will get longer, more conversational and more specific - and optimizing only for the exact two-word keyword starts leaving money on the table. The target is intent and the full question, not the loose term. I won't re-explain AI Mode here - I broke it down in detail in AI Overviews vs AI Mode and the AI Mode guide.
Search agents: Google now watches the web for you
This is the bigger shift - and the one fewest people noticed. Google launched "information agents": agents that work 24/7 in the background, reason across blogs, news, social posts and fresh data (finance, shopping, sports) and send you a synthesized summary when something changes in what you care about, with the action ready to go. Search stops being something you do (pull) and becomes something that happens for you (push). For now, it reaches AI Pro and Ultra subscribers first. For a brand, the implication is huge: if an agent is watching a topic where you want to be, either you're a fresh, clear, recognizable source it picks up - or you simply don't exist in that loop.
What this changes for your business
Three practical consequences, in order of impact:
- Intent over keywords. Write for real, complete questions, answer-first in each section. Cover the topic and the follow-ups, not a single two-word term.
- Freshness becomes a lever. Agents running 24/7 reward what's up to date. Real dates, recent data and maintained pages move from hygiene to competitive advantage.
- Being the chosen source (GEO). Whether in the box's answer or an agent's update, the game is to be citable and unambiguous: clear entity, sourced data, structured content. That's the work of GEO, and it has never been this literal.
And before changing anything: isolate in Search Console and GA4 what already comes from these surfaces. Decide with data, not headlines - that's the difference between strategy and reaction.
What doesn't change (and the hype to discount)
Before you rebuild your site: almost all of this is rolling out, much of it still tied to subscribers and specific markets. Gemini 3.5 Flash is AI Mode's engine - not a lever you pull directly. And the fundamentals haven't changed: without a solid technical base and content with real value, no intelligent box or agent will save you. The rule holds - measure what's already live in your market and adjust with data. Without measurement, this is faith; with measurement, it's management. That's exactly the work - entity, citable content and measurement - I do in the GEO service.

Common mistakes and how to do it right
Every Google announcement triggers panic. What separates a level-headed response:
| Avoid | Do |
|---|---|
| ✗ Rebuilding the site in a hurry over a feature still rolling out | ✓ Understanding first what's already live in your market and measuring with data |
| ✗ Staying stuck on 2-3 word keywords | ✓ Optimizing for intent and long, conversational questions |
| ✗ Ignoring content freshness | ✓ Keeping data and pages up to date - 24/7 agents reward freshness |
| ✗ Assuming 'being on Google' is enough for the agents | ✓ Being a clear, citable, recognizable source the agent picks (GEO) |
