AI visibility is usually broken down into mention rate, citation rate and share of answer. Mention rate is the share of questions whose answer names the brand in the body; citation rate is the share whose sources include your site; share of answer is your brand's portion of all the business mentions in the answers.
Answers to the same question vary by engine, language and time, so you can only see change by fixing the question list and measuring repeatedly.
Formula
Mention rate (%) = answers that mention the brand ÷ total questions × 100
Sample If the brand name appears in 9 answers out of 20 questions, the mention rate is 45%.
