Visibility Score

What you get

One score, not a loose ranking table

The Visibility Score combines mention + position into a single number: 100 if you're the #1 answer, 0 if you're not mentioned.

Clear trend over time

Watch the daily or weekly evolution chart and immediately spot whether a campaign or content change moved the needle.

Share of Voice vs. competitors

Know what portion of total mentions in your category belong to you, month over month.

Visible danger zone

The score flags when you're close to disappearing from answers, so you act before losing visibility entirely.

How it works

  1. We run your prompts daily

    Every execution against ChatGPT, Gemini, Claude, Perplexity, and more feeds the score calculation.

  2. We calculate the Visibility Score

    We combine whether you were mentioned and at what position, weighted by actual mention frequency — not just average rank.

  3. Track the trend and act

    Use the score to prioritize which prompts and which content need work.
