Summary: Google's AI Overviews now appear in 43% of U.S. searches, up from just 15% a year earlier, according to a new Similarweb report. The findings illustrate how quickly AI-generated answers are becoming a standard part of Google Search, while AI Mode is encouraging longer, more conversational queries. The report also highlights a growing disconnect between AI visibility and website traffic: citations are increasing, but referral clicks remain inconsistent. Alongside Cloudflare's new "Pay Per Crawl" initiative, the data points to a broader shift in how publishers, marketers and businesses may need to think about search visibility. For Miami's digital economy, where hospitality, healthcare, real estate and professional services depend heavily on search discovery, the implications are significant.
Type "best Cuban restaurant in Brickell" into Google today and there's a good chance you'll see an AI-generated summary before the first traditional website result.
A year ago, that was rare. Now it's increasingly the norm.
New data from market intelligence firm Similarweb shows just how quickly that shift has happened. Google's AI Overviews—the generated summaries that appear above traditional search results—now show up in 43% of U.S. searches, nearly triple the 15% recorded a year earlier, according to Similarweb's 2026 Generative AI Landscape Report.
AI Search Is Becoming the Default
The growth isn't limited to AI Overviews.
Google's more conversational AI Mode, which allows users to ask follow-up questions without starting a new search, saw web visits grow from 126 million in June 2025 to 279 million in May 2026. Google has separately said AI Mode now serves more than one billion monthly users, although that figure measures something different from Similarweb's web traffic estimates.
Search behaviour is changing alongside the technology.
Similarweb found that average search query length increased 5.4% following AI Mode's rollout, suggesting people are increasingly searching with natural-language questions rather than short keyword phrases.
"People are now adopting a new, more natural way to search and discover."
That behavioural shift matters.
For more than two decades, businesses have optimised websites around how people searched Google. As users increasingly ask complete questions instead of typing keywords, the traditional search playbook is evolving toward visibility inside AI-generated answers.
Citations Rise, But Traffic Doesn't Always Follow
The report also highlights a growing tension between AI platforms and the publishers whose content powers them.
ChatGPT responses containing web citations increased from 1.3% to 6.8% over the past year.
But citations don't necessarily translate into traffic.
Similarweb found that 65% of URLs cited by ChatGPT were deep product or article pages, while nearly 59% of referral clicks landed on homepages instead.
In other words, AI systems often extract information from highly specific pages but direct users somewhere more general when they click through.
That disconnect creates a real challenge for publishers and e-commerce businesses trying to understand whether AI visibility ultimately generates meaningful traffic and revenue.
The report also notes that Cloudflare has introduced Pay Per Crawl, currently in private beta, allowing website owners to charge AI crawlers for access or block them entirely using an HTTP 402 Payment Required response.
What This Means for Miami
Miami's economy depends heavily on businesses that are discovered online, from hospitality and real estate to healthcare providers, professional services and a growing startup ecosystem.
As AI Overviews occupy more space within Google Search, businesses that once focused primarily on traditional rankings may need to rethink what online visibility actually means.
For Miami's expanding community of marketing agencies and martech companies, the shift presents both a challenge and an opportunity. Businesses are increasingly looking beyond blue links toward accurate representation inside AI-generated answers, creating demand for AI visibility and citation strategies alongside traditional SEO.
Healthcare providers and law firms across South Florida should also pay close attention to how AI systems summarise their services, since inaccurate or incomplete AI-generated information could influence customer decisions without users ever visiting a website.
For researchers at the University of Miami and Florida International University, the report provides another real-world example of how AI is reshaping search behaviour, digital publishing and the economics of online discovery—trends that will continue influencing Miami's technology and business landscape in the years ahead.
