Google’s AI‑driven search layer has moved from a novelty to the norm. SimilarWeb’s latest report shows AI Overviews—concise, AI‑generated answers that appear at the top of search results—now show up in 43% of all queries, a dramatic jump from just 15% a year earlier. The data underscores a fundamental change in the search experience: users are less likely to click through to external sites and more likely to stay within Google’s ecosystem.

During the same period, visits to Google’s AI Mode, the conversational interface that follows an Overview, climbed from 126 million in June 2025 to 279 million by May 2026. The platform’s growing reach reflects a broader trend toward longer, more natural language queries. SimilarWeb notes that the average search length has increased, indicating that people are swapping short keyword strings for full‑sentence prompts designed for the AI.

Publishers are feeling the pressure. As AI Overviews cite sources without generating clicks, many news and content sites report a sharp dip in referral traffic. The citation rate in AI responses has risen more than fivefold over the past year, yet only 6.8% of U.S. desktop ChatGPT queries included a citation as of May 2026. Travel, retail, and sports queries see higher citation frequencies, but the overall impact on ad revenue and site visits remains concerning.

In response, Cloudflare introduced tools that let publishers block AI crawlers unless the AI providers pay for content access through its marketplace. The move aims to restore some of the lost traffic and compensate creators for the use of their material.

There are signs of a modest rebound for publishers. After a May 7 search update, the share of AI‑driven searches that led users to external webpages rose from 25% in March 2026 to nearly 60% by the end of May. The shift suggests that users are taking advantage of more prominent blue‑link listings when they appear alongside AI Overviews.

Overall, the data paints a picture of Google evolving from a simple index to a primary destination for information. While the company enjoys higher engagement metrics, the trade‑off is a dwindling flow of traffic to the broader web, prompting publishers and tech firms to seek new ways to monetize AI‑generated content.
