Specification

The 5 Measurement Pillars of Emphanic

12 questions, 4 assistants

48 measurements per search termBusiness name and variantsCompetitors logged

Per search term we ask 12 questions the way a buyer would, to ChatGPT, Claude, Perplexity and Gemini. That is 48 measurements, all with web access on, so you see what a customer gets today.

We check every answer for your business name and its known spelling variants. At the same time we log which competitors the assistant recommends instead.

How the score works

Scale 0 to 100Outages do not countAverage of 4 assistants

Your score runs from 0 to 100. Per assistant, that is the percentage of questions where your business gets named. The total score is the average across the four assistants.

An outage at an AI provider does not count against you: unanswered questions fall out of the calculation. Your score never drops because of someone else's downtime.

Mathematical denominator & score calculation
Score (0–100)=(Total Mentions÷Valid Answers)×100

Measured again every week

Answers vary each timeSame 48 questions every weekTrend, not coincidence

AI assistants do not give the same answer every time. A single measurement is a snapshot, not a guarantee.

That is why we repeat the same 48 questions every week. You see a trend instead of a coincidence, and you know whether a fix actually works.

The fact check on your site

No AI in this partSource code checked directlyPage path as proof

Alongside the AI questions, we check your own website: are your prices, hours and other core facts readable in the text and in structured data (JSON-LD)?

This part uses no AI. It is a direct check on your source code, so for every fact we find you get the page path and the literal text fragment as proof.

Limits of the measurement

No invented numbersMeasured again every weekNo guaranteed position

We report only what we measure: mentions, sources and facts from your source code. No invented numbers, no sentiment score we made up.

We measure your position again every week. Nobody can guarantee a fixed spot in ChatGPT, because an assistant builds every answer fresh.
