Ranges overlap month to month. We only call something a win when it clears the band — ChatGPT +3 does, AI Overviews −1 doesn't.

WHERE TO LOOK

Google surfaces (AI Overviews, AI Mode) lag the rest — and they lean hardest on listings. See sources, p. 04.

WHAT THE NUMBERS MEAN

A mention rate of 12% ±5 means: across 30 sampled runs, Fontaine appeared in 12%, and we're 90% confident the true rate sits between 7% and 17%. Month-over-month changes inside that band are reported as noise — even when they'd look good on a chart.

WHAT WE DON'T MEASURE

Conversions, calls, or bookings — pair this report with your call-tracking. We also don't measure prompts nobody asks; the pack is built from real query patterns for the vertical + city.

ENGINE CHANGELOG (JUNE)

jun 14 — AI Overviews layout change in fr results; local-pack citations shifted. Flagged, not treated as client movement. · jun 02 — AI Mode added to the panel (first month; no trend yet).
