Four sentences to keep
Set the frame
”AI engines do not return the same answer every time, even to the same question. We report the line over days, and changes inside normal variation are not meaningful.”
Report each engine
”Visibility on Gemini rose; on ChatGPT it fell. The two are not one trend, so we report them separately.” Never one combined score.
Name the cause
A sudden move that shows across every brand on one engine is the engine changing, not the client. Say so, and compare before and after as two series.
Link the method
Every number on the page links to its definition on GEO metrics and to the AI Visibility Truth methodology.
Two brands, ten days, from AI Visibility Truth
9–18 October 2026, one answer per question per engine per day. ChatGPT is the only engine that returns the pages it read; for Gemini every returned page is a cited page.
One report, then the line
Order Brand Perception Truth for the client’s main page (€150, next day): the sixteen answers, the three lists and the fix list. Then follow the questions every day with AI Visibility Truth (from €50 / month per brand).
