The way people find businesses is moving from ten blue links to a single AI answer, and the old dashboards do not measure it. mention.report is the standing reading on how findable brands are inside AI search: the prevalence, the engines, and the widening gap between ranking and being cited.
When an AI answer appears, the user usually has what they need before any link. The reading is starkest inside the AI surfaces themselves, where the answer is the entire experience.
A randomized field experiment found that AI Overviews cut outbound organic clicks by 38% on the queries where they appear, pushing the zero-click rate on those queries from 54% to 72%. The effect was strongest when the Overview sat at the top of the page, which it did 85% of the time.
Gartner expects traditional search query volume to fall around 25% as answer engines absorb the everyday questions that used to start on Google.
ChatGPT opened the category and still leads it, but its near monopoly has fractured. Measured by brand referral traffic, four engines now split almost the entire market, and the mix keeps moving month to month. Where your customers ask matters as much as what they ask.
Read the scale before the share. AI platforms now generate roughly 45 billion sessions a month worldwide, and about 83% of that happens inside mobile apps that browser-based analytics never see. The shift is larger than most dashboards report, because the dashboards are looking in the wrong place.
Methodologies differ. Other panels that weight by total query volume still put ChatGPT near 60% of AI search with Gemini and Copilot next. We show the spread on purpose. A single tidy number would be less honest than the range.
A high Google ranking used to guarantee visibility. In 2026 it guarantees nothing about whether AI will cite you.
This is the finding that should move budgets. The overlap between holding a top-ten Google ranking and being cited in the AI Overview for that same query has collapsed in under a year. The page that wins the search result is increasingly not the page the AI quotes.
When an AI Overview appears, organic click-through has been measured to drop by 58 to 61% for the pages that used to win the click. The traffic does not simply vanish. It reroutes to whoever the model decided to cite.
Which makes citation the new ranking. Brands cited inside an AI Overview earn about 35% more organic clicks and 91% more paid clicks than those left out of it. Being in the answer is now the position worth fighting for.
The instinct is to mourn lost traffic. The data argues the opposite. People who arrive from an AI answer have already done their research inside the answer, so they land further down the decision and convert at rates traditional search cannot touch.
Independent studies put AI-referred visitors at roughly 4.4 times the value of the average organic visitor, converting about three times as often. 79% of consumers now use some form of AI-enhanced search, and roughly 70% say they trust the generated results.
One structured visibility program took a company from 2.4% to 12.9% AI visibility in 92 days, with a fifth of its demo requests influenced by AI search. The lever exists. Most brands are simply not pulling it yet.
The full edition includes the industry-by-industry breakdown, the engine citation patterns, and the playbook for moving from ranked to cited. Add your work email and the full report opens right away.
Type in a brand and get an instant AI Reach score, benchmarked against the barometer. It is the fast version of the full diagnostic, and it tells you in seconds whether the engines can find you.
A low score points to the fix: visibility and authority through Mention, accessibility through ax4e, and a full diagnostic that ties the signals together.
The barometer does not run on a single feed. Each reading is assembled from multiple independent measurements, the spread is shown where sources disagree, and every edition carries its date so movement is comparable over time.
Pull the latest public measurements on AI search prevalence, engine share, and citation behavior.
Cross-check each figure across panels and methods. Where they diverge, we publish the range.
Set the readings against the prior edition so the direction and pace of change are visible.
Release on a fixed cadence under a dated edition, built to be cited and re-checked.
