Google’s AI Overviews now show up in 43% of searches, up from just 15% a year ago. That’s according to a new report from market intelligence firm Similarweb, covered by TechCrunch AI. What stands out here is the speed. In twelve months, AI answers went from a novelty layered on top of search to the main event.
The shift is bigger than one feature. Google is turning itself from a gateway to the web into a destination you never leave.
What the data actually shows
The numbers paint a clear picture of changing behavior, per TechCrunch AI’s reporting on the Similarweb findings:
- AI Overviews appeared in 43% of searches by mid-2026, nearly triple the 15% from a year earlier.
- AI Mode, Google’s more conversational search layer, jumped from 126 million visits in June 2025 to 279 million by May 2026.
- Average search length is rising. People are typing longer, more natural questions instead of short keyword strings.
That last point matters more than it looks. Users are learning to talk to search like they talk to a chatbot. Google drops them into an AI Overview, then hands them off to AI Mode to keep digging. The whole journey happens on Google’s turf.
Why publishers are nervous
When Google answers the question itself, there’s no reason to click a blue link. The site that produced the underlying information gets cited, maybe, but not visited.
Similarweb says the number of AI responses that include a citation rose more than fivefold over the past year. Sounds encouraging. But a citation isn’t a click, and news publishers have been hit hardest as referral traffic dries up.
This is why Cloudflare stepped in. TechCrunch AI notes the company rolled out tools that let publishers block AI crawlers unless the AI firms pay for access through a marketplace. That’s the fight taking shape: content owners want to be paid when their work trains or feeds an answer engine.
A small opening for the web
There’s one bright spot. On ChatGPT, U.S. desktop referrals improved sharply after a May 7 update. The share of visits that actually landed on a webpage more than doubled, from 25% in March 2026 to nearly 60% by the end of May.
The takeaway: when prominent links are available inside AI results, people do click them. The traffic isn’t gone. It’s conditional on how the interface is designed. Still, just 6.8% of U.S. ChatGPT desktop queries carried citations as of May 2026, so the overall pipeline back to publishers remains thin.
Where this goes next
Project this out two or three years and the direction is hard to miss. If AI Overviews are already in 43% of searches, the default within a couple of years is an answer, not a link. The open web’s traffic model, built on Google sending visitors outward, is being rewired in real time.
Here’s what to do about it now:
- Publishers and marketers: Stop measuring success by search referrals alone. Build direct channels you own, like email and communities, where no algorithm sits between you and your audience. A newsletter list doesn’t care whether Google sends clicks.
- Businesses relying on SEO: Optimize to be the cited source inside AI answers, not just to rank. Structured data, clear authorship, and quotable facts increase your odds of being the reference an AI pulls from.
- Everyone watching the money: Track the Cloudflare-style pay-for-access marketplaces. If licensing content to AI companies becomes standard, that’s a new revenue line, and a new negotiating table.
Google spent two decades training us to search and click away. It’s now training us to search and stay. The businesses that thrive in that world are the ones building relationships that don’t depend on borrowed traffic.
