🔬 How we measure
How we measure
The short version lives here. The full method — including what it can't tell you — lives on one page, and we don't keep a second copy of it.
There are two different kinds of number in this product, and almost every misreading comes from mixing them up:
| What | What it is |
|---|---|
| The GEO score | A deterministic rubric we run against your site. Same site, same checks, same score. It describes your pages, not AI behaviour. Details → |
| The mention rate | A measurement of what engines actually said, sampled repeatedly, reported with an interval and a sample size. This is the one that can tell you something changed. Details → |
| Citation gaps | The third-party sources engines cite in your category where you're absent — ranked by how often they show up. |
The full methodology
Rather than paraphrase it into a second, subtly-different version, the complete method is published in one place and this page points at it. It covers what we measure, how the GEO score is composed, how we query the engines, what counts as an observation and what doesn't, and — the section worth your time — the limitations.
Why one copy? A methodology that exists in two places is a methodology that will disagree with itself. When the method changes, exactly one page changes.
