Per-prompt mention share
also called Mentions % (prompts tab)
Definition
Your share of all brand mentions made on one answer-engine prompt, across every tracked brand named for it.
How it's calculated
(your mentions for the prompt / all tracked brands' mentions for the prompt) × 100, returned empty when the prompt drew no mentions. The two legs are the same brand-mention query with and without the client filter, each summed per prompt and joined on the prompt key.
- Numerator
- Mentions of your brand on that prompt.
- Denominator
- Mentions of every tracked brand on that prompt.
Scope, grain and dimensions
- Grain
- One prompt for one tracked segment over one date range.
- Dimensions
- prompt · answer engine · intent · branded vs non-branded · country · device
- Required filters
- tracker or tracked segment id · date range
- Aggregation
- Per-prompt denominators differ, so these are not averaged into an account mention share.
- Metric type
- share · percent of that prompt's mentions

How to read it
Compared against the citation share on the same row, this separates being talked about from being used as a source, the two diverge on most prompts and the direction of the divergence is the useful part.
Caveats, freshness and failure modes
Empty means the prompt drew no mentions from any tracked brand, not that you scored zero against a populated field.
When the all-brand leg returns no row for a prompt, the denominator falls back to your own mentions and the share reads as one hundred percent.
The prompt tab reads the market-share brand-mention dataset. If the tracker has no market-share segment for the requested engine the tab returns no rows with a stated reason, rather than zeros.
Every figure is scoped to a tracked prompt basket, a sample, not a census, so the basket's coverage belongs beside the number it produced.
- Freshness
- ~1 day behind, Daily prompt runs, available the following day.
Common failure modes
- Reading it as a citation share because both columns sit on the same row and both end in a percent sign.
- Averaging per-prompt shares into one account-level figure.

The confusions that cause the most wrong decisions.
Per-prompt mention share Per-prompt citation share Compare definitions →
Separate measures over the same prompt from two different datasets: mentions count your brand being named, citations count your URL being sourced. They routinely diverge and the direction of the divergence is the read.
Per-prompt mention share Prompt share-of-voice percentage Compare definitions →
This divides by all tracked brands' mentions on the prompt; the share-of-voice percentage divides the same population's weighted citations-plus-mentions, so it moves with the citation half too.
