We measure ourselves with the instrument we point at your brand.
Every figure below is read from our own tracking engine when this page is built, and it rebuilds every hour. The prompt set is published in full. So is the competitor list the maths depends on. So are the questions where we do not get named at all.
Last read 10 September 2026, 19:55 UTC.
RankZero was named in 88 of the 3,072 AI answers our own prompt set produced in the 30 days to 10 September 2026.
31 published prompts, run against ChatGPT, Google AI Overviews, Google Gemini and Perplexity. The denominator is every one of those 3,072 answers, not a subset we picked.
Why this denominator, and not our own headline metric.
Share of voice, the figure our product leads with, is measured against a list of competitors we choose. Change the list and the percentage changes, backwards as well as forwards, without a single answer being different. So this page divides by the prompt set instead. That set is published below, it is the same set every day, and nothing we do to our own settings can move it. Share of voice is still on this page, further down, with that warning attached to it.
This is not a traffic number.
It counts how often an AI answer names us. It says nothing about how many people then visited this site, and we are not going to imply otherwise. Those are different measurements and only one of them is on this page.
Share of voice, and why it sits below the number above.
Share of voice divides by a smaller number than the headline does. Its denominator is the 1,808 answers that named at least one brand on our tracked list, not all 3,072 answers. Ranking position works the same way, against the 19 brands listed further down.
That list is one we chose, which means the percentage moves when we change it. Stop tracking the three brands named most often (Ahrefs, SE Ranking and Profound) and the very same 88 answers read 6.59% instead of 4.87%, without a single extra answer naming us.
It moves the other way too, and it just did. 5 of the 19 brands below (Semrush, Omnia, Rank Prompt, ZipTie AI and Radyant) were added to the list inside the window shown here. Adding a competitor pulls more answers into the denominator, so every other percentage falls, ours included, with nothing having changed in what the models actually said.
A number our own settings can move by points is not the one to lead a page like this with. That is the whole reason the figure at the top divides by every answer instead.
Checked on this render: our share of voice recomputed from the counts on this page matches what the tracking engine reports, to within a tenth of a point.
20 of these 31 questions did not name us once.
This is the whole set, not the flattering part of it. Every prompt we track is here with the number of answers it produced, how many named us, and the brand named most often in the ones that did not. Nobody in this category publishes the second table.

Country is the locale the prompt runs in, shown next to each one. 28 in United Kingdom, 2 in United States and 1 in Germany. The set is weighted the way it is because it grew out of the questions our own buyers ask, not out of a country plan, and that is a limit of this measurement rather than a feature of it.
The 19 brands the ranking is measured against.
A share of voice figure means nothing without the set it is a share of. This is ours, as it stands at the timestamp on this page, with the date each brand was added.

How this is measured, and what it cannot tell you.
How it is measured
Each of the 31 prompts is sent to ChatGPT, Google AI Overviews, Google Gemini and Perplexity on a daily cycle, in the country listed beside it. That produced 3,072 answers in the 30 days covered here, the first on 11 August 2026 and the last on 10 September 2026.
A mention counts once per answer. An answer that names us three times is one answer, not three. We read the answer text the model returned, not a search result page.
The figures come from the same tables and the same query that serve our customers' dashboards and our public API. There is no separate reporting path for this page.
What it cannot tell you
The brand list is closed. An answer that names a company nobody has added to a tracked list is recorded as naming no one, so "answers that named someone" is a floor and not a count of the whole field.
The window stops at 90 days. Anything older than that is not reachable through this measurement, so this page cannot show you a year of history and does not pretend to.
And the number moves. This page reports the window it is looking at right now, not the best window we have ever had, which is why the seven day figure sits next to the thirty day one at the top.
There is no trend line on this page, on purpose. When a brand joins the tracked list, only the most recent few days of answers are re-read against it, so a share of voice chart spanning that moment would slope gently downwards when what actually happened was a settings change on one day. We would rather show you two windows that divide by the same fixed prompt set than a curve that cannot tell those two things apart.
We will run this on your prompts and show you the same table.
The audit call maps the questions your buyers actually ask, runs them against the same models, and gives you your own version of the page you just read. Including the rows where you lose, because those are the ones worth working on. See what the program covers.
