This is a fully-sourced reference to Conductor's 2026 AEO/GEO Benchmarks Report, described as the first large-scale industry analysis of how AI-powered discovery reshapes brand visibility. The headline figures: AI referral traffic is about 1.08% of all website traffic, ChatGPT drives ~87.4% of that referred traffic, and Google AI Overviews appear in ~25% of searches. This page collects the report's numbers, each tied to its source.

Last reviewed: 27 June 2026. All figures below are from Conductor's 2026 AEO/GEO Benchmarks Report, first published 13 November 2025 and last updated by Conductor in April 2026. The figures were verified against Conductor's own report page and corroborated across independent coverage (Business Wire, The AI Journal, and multiple secondary analyses). It is a single-vendor dataset, so treat the direction as firmer than any single number, and attribute anything you quote to "Conductor, 2026."

What did Conductor analyse?

The report's scale is what makes it useful as a benchmark. Conductor's stated methodology:

Metric Figure Source
Total sessions analysed 3.3 billion Conductor, 2026
AI-traffic sessions specifically 35.7 million Conductor, 2026
Domains studied 13,770 Conductor, 2026
Industries / sub-industries 10 / 22 (mapped to GICS) Conductor, 2026
AI-generated responses examined 17 million Conductor, 2026
Citations tracked over 100 million Conductor, 2026
Google searches analysed for AI Overviews 21.9 million Conductor, 2026

The takeaway: this is one of the largest public datasets on AI visibility to date, which is what makes its benchmarks worth referencing, while remembering they reflect Conductor's enterprise-domain sample, not the whole web.

How much traffic does AI actually refer?

Conductor's most-cited finding is that AI referral traffic is still a small slice of the whole, but growing and very uneven by sector:

Metric Figure Source
AI referral traffic (all industries) 1.08% of total Conductor, 2026
Month-over-month growth ~1% Conductor, 2026
ChatGPT's share of AI referral traffic 87.4% Conductor, 2026
Highest sector. IT 2.80% Conductor, 2026
Second. Consumer Staples 1.91% Conductor, 2026
Lowest. Communication Services 0.25% Conductor, 2026
Lowest. Utilities 0.35% Conductor, 2026

The 1.08% figure is easy to dismiss as trivial, but two things make it matter: it is compounding monthly, and, because AI answers are often zero-click. Referred visits undercount AI's real influence on a buying decision. Much of AI's impact shows up as brand awareness and shortlisting that never registers as a click, which is why Conductor's own advice is to measure citations and mentions, not just referrals. We make the same case in from clicks to citations.

How prevalent are Google AI Overviews?

Across the 21.9 million Google searches Conductor analysed, about one in four returned an AI Overview:

Sector AI Overview prevalence Source
All searches (average) 25.11% Conductor, 2026
Healthcare (highest) 48.75% Conductor, 2026
Financials 25.8% Conductor, 2026
Consumer Staples 6.82% Conductor, 2026
Real Estate (lowest) 4.48% Conductor, 2026

The ~25% average sits in the same range as other mid-2026 estimates (Google's own and third-party trackers have put AI Overview prevalence between roughly 16% and 25%, depending on query mix and date). The sector spread is the more actionable point: in Healthcare nearly half of searches surface an AI summary, so the AI Overview optimisation stakes are far higher there than in Real Estate.

Who wins the citations?

Conductor reports that within several industries, third-party publishers and marketplaces, not the brands themselves. Capture the largest citation shares:

Domain Citation share Industry Source
Amazon 17.99% Consumer Staples Conductor, 2026
Zillow 7.36% Real Estate Conductor, 2026
NerdWallet 6.73% Financials Conductor, 2026
Google 5.34% IT Conductor, 2026

In Financials, in other words, a publisher like NerdWallet is winning more AI citations than many traditional banks. This is the same dynamic behind why AI loves listicles: for category questions, engines lean on neutral-looking marketplaces and review publishers over brand-owned pages. The strategic implication is earned placement in those sources, not just optimising your own site.

How should you use these benchmarks?

Treat this as a dated benchmark, not a target. Every number here is Conductor's own, drawn from an enterprise-domain sample over a defined window, so cite Conductor and the date when you reuse one, and hedge as "as of the 2026 report." Because live retrieval favours recently-updated pages, we keep references like this on a refresh cadence and update figures substantively as new editions land. Conductor's report is also published in per-industry cuts, so the sector benchmark that matters most is the one for your industry, not the cross-industry average.

The one figure that ultimately matters is your own: whether the engines surface, cite, and recommend your brand for the questions your customers ask. Measured over time, across engines, against your category benchmark. That is precisely what Buffy Intel is built to measure, turning industry benchmarks like Conductor's into a read on your actual share of voice.

Frequently asked

How much of website traffic comes from AI referrals in 2026?

Per Conductor's 2026 AEO/GEO Benchmarks Report, AI referral traffic accounts for about 1.08% of all website traffic across the 10 industries it analysed, growing roughly 1% month-over-month. It is small but rising fast, and uneven by sector. IT sees about 2.80% while Communication Services sees about 0.25%. These are Conductor's figures from its own dataset, so read them as directional benchmarks rather than universal truth.

Which AI engine drives the most referral traffic?

Conductor reports that ChatGPT accounts for about 87.4% of all AI referral traffic across the industries it studied. A dominant share that matches other 2026 analyses showing ChatGPT as the primary source of AI-referred visits. This is a single-vendor measurement of referred clicks, not of citations or mentions, which distribute more evenly across engines.

How often do Google AI Overviews appear?

Conductor found that about 25.11% of the 21.9 million Google searches it analysed surfaced an AI Overview. Roughly one in four. Prevalence varies sharply by sector: Healthcare topped 48% while Real Estate sat near 4.5%. Google's own and other 2026 estimates put AI Overview prevalence in a similar 16-25% range depending on query mix and date.
