Visibility vs citation share vs share of voice: three metrics, three questions
Visibility, Citation Share and Share of Voice sound alike but answer different questions. A comparison of what each measures, with Promptwatch's new Topics page as the worked example.
Quick verdict
Visibility asks whether the engine names you. Share of Voice asks how much of the conversation you take compared with rivals. Citation Share asks how much of the sourcing is yours. They can disagree, and when they do the disagreement is the finding. Since 26 October 2026, the Topics page in Promptwatch shows all of them, plus Avg. Position and Sentiment, for every topic (changelog). That makes it the easiest place we know to see the three side by side.
Why teams confuse them
All three are percentages, all three are reported per prompt, topic or period, and most dashboards put them in neighbouring tiles. But they count different things. One counts answers. One counts brand mentions. One counts links. Mix them up and you will celebrate a number that is measuring something other than what you meant.
The three definitions
Visibility
The share of tracked answers in which your brand appears. If you run 100 responses for a topic and you are named in 30, visibility is 30%. It says nothing about competitors, nothing about position and nothing about whether the engine linked to you. It is the most basic question: are we in the answer at all?
Share of Voice
Your mentions as a fraction of all tracked brand mentions in the same answers. If three brands are named across the panel and you account for a third of those mentions, that is your share. It depends on the competitor set you track, so adding or removing a rival changes it. Our guide to how to calculate and compare share of voice shows the arithmetic.
Citation Share
This one is new in Promptwatch. The changelog defines it as the citations of your sites divided by all citations in the topic's answers. It is about sources, not names. An engine can mention you often and cite someone else's page each time, which gives you good visibility and low citation share. The reverse also happens: your pages are cited as background in answers that name competitors.
When they disagree
| Pattern | What it usually means | What to check next |
|---|---|---|
| High visibility, low Citation Share | Engine knows your name but sources claims elsewhere | Which third-party pages get cited, and whether your own pages answer the same question |
| Low visibility, decent Citation Share | Your content informs answers that recommend others | Whether your pages position you clearly as an option |
| High Share of Voice, low visibility | You dominate the few answers that name anyone | The prompts where nobody is named, or the panel is too narrow |
| All three low | You are not part of the topic yet | Content gap and crawler access, in that order |
These are our reading of the definitions, not vendor claims. Treat them as hypotheses to test.
What the Topics page adds
Per the changelog, Topics moved out of the Prompts tabs into its own page under Trends. Every topic and its prompts show Visibility, Citation Share, Avg. Position, Share of Voice and Sentiment, for the dates you pick. The By Competitor and By Rank views have a switcher to choose the metric to compare. (By Position was renamed By Rank on Topics and Prompts.) A tooltip on each tab explains the view.
Two practical consequences. First, you can find the topic where your Share of Voice is fine and your Citation Share is poor, and that is a clean content brief. Second, you can compare a metric against a competitor topic by topic, rather than across your whole prompt set where strong areas hide weak ones.
Promptwatch also has heatmaps that compare any two dimensions, such as brands, models, topics and countries. Use the heatmap when you want to see where a gap sits, and the Topics page when you want to rank topics by a metric. The 360 Insights dashboard adds Topic Insights, which groups the pages of your site by topic and shows crawls, citations and clicks per topic, so you can check whether the pages behind a weak topic are being reached at all.
Where other tools stand
Our catalog does not record a Citation Share metric for any other tool. Several track share of voice. The AI share of voice tracking tools comparison covers who reports it and how. Profound's entry mentions citation share and answer-level analytics, so it is the one other tool in our catalog where the idea is named, though we do not know that it is calculated the same way. Treat any vendor's "citation share" as a label until you have read the definition.
A reading routine
- Pick the five topics that matter commercially.
- Open the Topics page and set the date range to a full reporting period.
- Sort by Visibility and note the weakest topic.
- For each topic, put the three numbers next to each other and match the pattern in the table above.
- Open the By Competitor view for Citation Share and see who holds the sourcing.
- Choose one topic and one action, whether a new page, a refresh or a fix to crawler access.
- Re-read after the next period.
Do not read a single week. AI answers shift between runs, and a topic with few prompts will swing wildly. If a topic has only two or three prompts, add more before you decide anything.
Caveats worth stating
None of these metrics measure revenue. A high Citation Share is not a promise of traffic. For that, you need visitor data, which in Promptwatch sits in Visitor Analytics with conversions. Citation Share also depends on how many sites you tell the tool are yours, so check that your domains, subdomains and any brand sites are configured. And all three metrics inherit the quality of your prompts: a panel written from keyword lists measures the questions your SEO team imagines, not the ones buyers ask.
Who should pick which
- Visibility for a first read and for board-level trend lines.
- Share of Voice when the argument is against specific rivals.
- Citation Share when the question is about content, sources and who the engine trusts on the topic.
- All three on one page if you manage several topics and need to explain why they differ. This is where Promptwatch's Topics page earns its place.
Bottom line
Stop asking which metric is best. Ask which question you are trying to answer, then pick the number that answers it. If your questions are about topics, the page that shows all three together is the fastest route, and Promptwatch is the one to evaluate first for that.
