How the evidence is built.
A transparent method for tracking non-deterministic AI answers without pretending they behave like fixed rankings.
1. Controlled prompts
Each brand is monitored with repeatable buyer-intent prompts tied either to its product category or to its service and US location. mentionpop runs the configured prompt set on a weekly cadence.
2. Two distinct surfaces
GEO observations cover generative answers from ChatGPT and Gemini. Agency AEO observations cover Google AI Overviews, featured snippets, and People Also Ask.
3. Evidence capture
Each successful observation records the engine or surface, timestamp, mention status, position when detectable, cited URLs, and a capped copy of the raw response.
4. Rates and deltas
Mention rates use successful observations only; failed API calls do not count as brand misses. Reports compare the current observation window with the previous window and display GEO and AEO separately.
Limits
AI output varies across time, wording, model versions, personalization, and device. mentionpop is a change-detection and evidence system, not a universal ranking oracle or a guarantee of traffic, citations, or revenue.
