AI Referral Traffic Still Can't Offset Google Search Losses

Publishers looking to chatbots for a new source of readers got a mixed answer in 2025. AI assistants are sending more visitors than they were a year ago, but the totals remain small. Meanwhile, the clicks those same publishers used to get from Google keep shrinking. The data points to a widening gap that AI referrals are nowhere near closing.

The growth is real, but the base is tiny

The headline growth figures look impressive. From September to November 2025, ChatGPT referrals rose 52% year over year, and referrals from Google's Gemini jumped 388% over the same stretch, according to Similarweb data shared with Digiday.2 ChatGPT still sends the most referral traffic of any AI tool, but Gemini is gaining on it.2

Those percentages start from a very low base. Across 10 major industries, AI platforms account for an average of only about 1% of overall web traffic, according to the marketing platform Conductor.2 Digiday's year-end assessment put it plainly: ChatGPT referral traffic nearly doubled but still makes up a very small share of publishers' total traffic, and referrals from tools like ChatGPT and Perplexity are not enough to offset declines in search.2

Google's AI Overviews are eating the clicks

The search side of the ledger is where the losses are piling up. Google rolled out AI Overviews to all U.S. users in May 2024, and publishers have since reported significant drops in traffic.1 Pew Research Center tracked 68,000 real search queries and found that users click a traditional result 8% of the time when an AI summary appears, compared with 15% when no summary is shown.13 That works out to an average click-through decline of roughly 46%. Other independent studies from 2024 and 2025 put the reduction somewhere between 34% and 46%. In the worst cases, such as those reported by DMG Media, the drop reached 89%.1

Publisher-level numbers show the same pattern. Chartbeat data reported by Axios showed Google Search pageviews across its publisher network fell 34% between December 2024 and December 2025.3 Business Insider has reported traffic down 35% year over year, and outlets including HuffPost and The Washington Post have described steep declines as generative AI has changed how people look for information.4

The exposure is also growing. One outside study cited by Marketplace found AI summaries went from appearing on about 15% of searches to roughly 40% within a year.4 Digiday likewise noted that AI Overviews cut click-through rates across a widening range of queries through 2025.2

Google disputes the scale

Google does not accept the most alarming readings. In a blog post, the company said it still sends billions of visits to websites and that traffic has not meaningfully fallen. It called outside research too pessimistic, including findings that 75% of users don't click through after seeing an AI summary.4 Google also points out that its AI summaries include links, and it has argued that the clicks it does send are "higher quality."14

That argument may hold for some content types. Search Engine Journal notes that the damage varies, with some categories of content holding relatively stable while others face much bigger changes.1 But Google has not released data that would let anyone check its claims, while the independent figures from Pew, Chartbeat and individual publishers all point the same way.

A business model coming apart

The pressure on Google is not only reputational. One analysis projects that Google's share of U.S. search advertising will fall below 50% in 2026, even as the company keeps expanding AI Overviews.3 Google is both causing this shift and exposed to it.

For publishers, the more lasting change may be how visibility is defined. The same analysis describes a model that separates three things that search used to bundle together: being cited by an AI system, being recommended by it, and actually receiving a referral visit.3 A page can be read and summarized by machines many times without producing a single human visit. Digiday reports that publishers are now concentrating on keeping their brands visible inside AI answers rather than relying only on clicks.2

What it adds up to

The sources differ on how large the search losses are, ranging from about a third to nearly 90%. They agree on the direction. The most reasonable reading is that AI chatbots are becoming a real referral channel but are not a replacement for search. Gemini's fast growth deserves attention, especially because Google controls both the summaries that reduce clicks and one of the fastest-growing chatbots that sends them. Still, a channel that delivers around 1% of traffic cannot make up for double-digit declines in a publisher's largest source of visitors.

Publishers planning for 2026 should expect search referrals to keep falling. They should treat AI citations as a branding opportunity rather than a dependable traffic source, and invest in direct relationships with readers that neither Google nor OpenAI can take away.
