AI Traffic Surges 66 Percent as Organic Search Slips Across Industries

Semrush’s latest read on the web says the traffic story is changing in plain sight: total visits were essentially flat in 2025, down just 0.43%, while AI traffic surged 66% and organic search slipped in 13 of the 17 industries it tracked. The twist is scale. Organic search still generated more than 1 trillion visits last year, and AI still accounted for less than 0.15% of total web visits. This is not a replacement story. It is a redistribution story.

That redistribution is showing up most clearly in visual and product-heavy categories. Beauty, apparel, food and retail kept growing in Semrush’s dataset, while other industries saw search demand shift earlier in the journey, sometimes into AI interfaces before a click ever reached a publisher or brand site. Semrush’s data suggests the old playbook, win more blue links and call it a day, is no longer enough if discovery now begins in an AI answer and finishes somewhere else.

Google’s AI Mode is the clearest example of how fast the mix is changing. Semrush said AI Mode traffic rose from about 1,600 visits in January 2025 to 38.2 million by December, even though it still represented only 0.01% of total traffic. Google first began rolling out AI Overviews to U.S. users in May 2024, then expanded AI Mode in the United States at I/O 2025 after earlier testing in Labs. That matters because 2025 was the year AI moved from a search feature into a traffic channel with real momentum.

The broader industry data points the same way. Previsible’s 2025 State of AI Discovery Report tracked 1,963,544 LLM-driven sessions over 12 months and found AI traffic was just 0.13% of total sessions, but concentrated on high-intent pages. SE Ranking put AI platforms at 0.15% of global internet traffic, with ChatGPT responsible for roughly 4 out of 5 AI-driven clicks. Cloudflare has since tried to quantify the crawl-and-referral imbalance directly, underscoring how hard it is for AI tools to send traffic back compared with the traditional web.

Semrush’s own earlier research had already flagged where this was headed, saying in July 2025 that AI search visitors could overtake traditional search visitors for digital marketing and SEO topics by early 2028. It also noted that ChatGPT weekly active users had grown 8x from October 2023 to April 2025, topping 800 million. The message for publishers and brands is blunt: AI is becoming an upstream influence on later visits, and the fight is shifting from ranking pages to being surfaced, cited and remembered across channels.
