How it is measured fairly
The questions should be the ones buyers ask, mostly without your brand name in them ("best sunscreen for oily skin in India"), because naming the brand in the question makes engines far more likely to mention it. Each question is asked on each engine, the answers are stored, and each answer is marked mentioned or not mentioned. Mention rate = answers that name you ÷ answers analysed × 100.
Why one check is not enough
AI answers vary between runs of the same question. A single check is a sample; repeated checks over time give a rate you can trust and compare.
What it does not tell you
Being named is not the same as being recommended. Read mention rate together with position (how early you appear), share of voice (how you compare with competitors) and the sources behind the answer.
How ClerAEO measures it
ClerAEO asks your buyer questions without your brand in them, stores every answer, measures across up to seven engines depending on your plan, reports each engine separately, and refreshes the questions on a schedule. See the Methodology page.
