How is an AI visibility percentage calculated?

Contxt editorial

For a mention-based measurement, divide the number of tested answers that name the brand by the number of eligible, successfully collected answers, then multiply by 100. Always read the denominator and collection scope alongside the percentage.

If 58 of 200 tested answers mention a brand, the measured visibility is 29%. This is an illustrative calculation, not a customer result or a claim about the brand’s share of all AI conversations. If the test used 50 prompts across four platforms, each prompt-platform answer is a separate observation.

Platform and buying-stage breakdowns can reveal what the overall score hides. A 29% aggregate could include strong coverage on one platform and little coverage on another. Similarly, a brand might appear in comparison answers but be absent from early research questions.

A failed request, an unavailable answer and an answer that genuinely does not mention the brand must not be treated as the same thing. Review collection completeness before interpreting a change. Rankings, sentiment and cited source counts are separate measures with their own definitions.

For repeat comparisons, check the prompts, platforms, dates and collection conditions. A changed prompt set can produce a changed percentage without demonstrating an improvement in the same buyer questions. See comparing visibility over time and Contxt’s reporting features.
