Google's AI-generated summaries, known as AI Overviews, appeared in 43% of US searches in 2026, up from 15% the previous year. Additionally, Google's conversational AI Mode saw a rise in web visits, growing from 126 million in June 2025 to 279 million in May 2026. These figures, reported by market intelligence firm Similarweb, highlight the increasing integration of generative AI within Google's search ecosystem.
By the numbers
Search Behavior and AI Integration
The introduction of AI Mode has led to a 5.4% increase in the average length of Google searches, as users adopt more natural-language queries. Google utilizes a technique called query fan-out to divide complex questions into subtopics, allowing the system to generate responses supported by links. While Google reported that AI Mode surpassed one billion monthly users in May, this figure is not directly comparable to Similarweb's web visit estimates.
Publisher Traffic and Citation Trends
Publishers have expressed concerns regarding referral traffic when content is used in AI-generated answers. In response, Google has updated AI Overviews and AI Mode to include more prominent references, direct links, and website previews. Similarweb noted that ChatGPT also increased its use of web citations, with the share of responses containing citations rising from 1.3% in June 2025 to 6.8% in May 2026. Data suggests that while AI services often cite deep-link content like specific articles, referral traffic is more likely to land on a website's homepage.
Emerging Monetization for Publishers
To address how AI crawlers access content, Cloudflare is testing a 'Pay per Crawl' service. This private-beta program allows website operators to set fees for AI crawlers, returning an HTTP 402 'Payment Required' response to unauthorized or unpaid requests. This system aims to provide publishers with more control over how their material is accessed and used by generative AI platforms.
