The definition, formula and a worked example for every number Opttab shows on the Dashboard and Prompts pages.
This page is the reference for every metric Opttab reports. Other pages link here instead of repeating the definitions.
All metrics are built from AI answers: the text one AI engine returned for one prompt on one run. Change the period or filters and every metric is recalculated from the answers that match.
Key terms
Term
What it means
Answer (or response)
The text one AI engine returned for one prompt on one run. Each answer belongs to the local day it was collected, in your workspace time zone (UTC by default).
Eligible answers
Every finished answer that matches the selected period and filters.
Mention
The answer names your brand or a tracked competitor. Opttab records two things: whether the brand was mentioned in the answer (yes or no), and how many times it was named (the mention count).
Citation
A web page or domain the answer links to or bases itself on.
Ownership
Every citation is labelled Your domain, A tracked competitor or Third party.
Tracked roster
Your brand plus the competitors you track. Brands that AI answers name but you don't track are called Discovered brands and are kept separate.
Branded prompt
A prompt that names your brand or one of your products.
How answers turn into metrics
Visibility counts answers. Share of Voice counts mentions. Share of Citations counts citations. That is why the three numbers rarely match.
Visibility
What it means
How often AI answers mention your brand.
Formula
Answers that mention you ÷ all eligible answers × 100
Example
You track 10 prompts on 4 AI engines, so one daily run gives 40 answers. Your brand appears in 12 of them. Visibility = 12 ÷ 40 × 100 = 30%.
Every eligible answer counts in the total, including answers that mention no brand at all.
An answer that names you five times still counts once.
On the Dashboard, the Visibility Score donut splits every answer into four slices:
Mentioned: you were mentioned on an unbranded prompt.
Branded: you were mentioned on a branded prompt.
Competitor branded: a tracked competitor was mentioned and you were not.
No response: neither you nor a tracked competitor was mentioned.
The same formula is used per brand (Leaderboard, Brand Visibility Trend), per topic (Visibility by topic), per country (Visibility by Market) and per prompt.
Branded prompts usually mention you, so they lift Visibility. Check the Branded slice to see how much of your score comes from them.
Share of Voice
What it means
Your share of all brand mentions, compared with the competitors you track.
Formula
Your mention count ÷ (your mention count + every tracked competitor's mention count) × 100
Example
Across the period's answers, your brand is named 30 times, Competitor A 50 times and Competitor B 20 times. Share of Voice = 30 ÷ 100 × 100 = 30%.
This metric uses mention counts: an answer that names you three times adds three.
Only your tracked roster is compared. Discovered brands are not part of the total.
Adding or removing a competitor changes the total, so it can move your Share of Voice even if your own mentions stay the same.
Share of Citations
What it means
How often the sources AI answers rely on are pages on your own website.
Formula
Citations to your domain ÷ all citations × 100
Example
The period's answers cite 80 sources in total. 8 of them are pages on your site. Share of Citations = 8 ÷ 80 × 100 = 10%.
Your website and any extra domains listed in Brand Hub under Other domains count as your domain.
