State of Zero-Click AI 2026
Half of all queries now end inside an AI answer. We're measuring exactly how much click-through has eroded across 200+ brands and 9 engines.
Why this study
Google AI Overviews coverage crossed 47% in early 2026. Zero-click rates on covered queries climbed past 60%. The same shift is happening on Perplexity (always synthesized), ChatGPT Search, and Copilot. Traditional GA4 / Search Console reporting underestimates the loss because the lost sessions never reach those tools.
BrandCited's scan corpus is the only public data set that measures the citation side and the click side of the same brand across all 9 major engines. The Q3 2026 study connects them.
Methodology (sample frame)
- · 200+ brands across SaaS, ecommerce, healthcare, finance, media
- · 9 engines: ChatGPT, Claude, Gemini, Perplexity, Grok, DeepSeek, Llama, Google AI Overviews, Microsoft Copilot
- · 90-day window: June 1 – August 31, 2026
- · Citation rate measured by the live BrandCited scan engine at low temperature for reproducibility
- · Click side cross-referenced with GSC + GA4 deltas for participating brands (opt-in only)
- · CC BY 4.0 license on aggregate findings; per-brand data anonymized in public release
Participate
We're recruiting brands willing to share read-only GSC + GA4 access for the 90-day window. Your data is anonymized in the public release; you get an early preview of your before/after click impact and a public mention in the methodology section.
