Share of Voice SEO:
Your AI Citation Share, Over Time
A share-of-voice number tells you where you stand today. History shows whether you're gaining or losing ground against named competitors - and exactly when the shift happened - across Perplexity, ChatGPT, and Google AI Overviews.
A Snapshot Doesn't Tell You If You're Winning or Losing
Share of voice is inherently relative - it's your citation rate measured against named competitors, not against nothing. But a single reading of that percentage only tells you today's position. It can't tell you whether last month you had more share and lost it, or whether a specific competitor made a move that's actively costing you ground right now.
History turns that single number into a trend line, with the shift points visible - so you can connect a change in share to what happened around it, on your side or a competitor's.
Share of Voice, Tracked Over Time
-
Trend Over Time
Share of voice is tracked as a history, not a single snapshot - so gains and losses against named competitors are visible as a chart, not a single percentage.
-
Named Competitor Comparison
Share of voice is calculated against the specific competitors you name, across your tracked keyword set - not an abstract score with nothing to compare it against.
-
Shift Points
Movement in share of voice is visible at the point it happened, across Perplexity, ChatGPT, and Google AI Overviews, so a shift can be connected to a specific cause.
Frequently Asked Questions
- What is AI citation share of voice?
- Share of voice, applied to AI search, is the percentage of tracked prompts or keywords where your domain is the cited source, compared to your named competitors, across AI engines like Perplexity, ChatGPT, and Google AI Overviews. A 40% share of voice on a topic means you're cited on 40% of the tracked queries for it - and your competitors split the rest.
- Why does share of voice history matter more than a current snapshot?
- A single share-of-voice number tells you where you stand today, but not whether that position is improving or eroding, or exactly when a shift happened. History shows the trend line - including the specific point where a competitor gained ground - which is what actually tells you whether something you changed worked, or something a competitor did is costing you.
- How is this different from a citation tracker?
- A citation tracker tells you whether you're cited on a given keyword right now. Share of voice history aggregates that across your tracked keyword set and competitors, over time, into a single trend - the difference between a single data point and a chart.
- Do I need to name competitors to use this?
- Yes - share of voice is inherently relative. Naming the competitors you actually compete with for citations is what makes the percentage meaningful, rather than an abstract score with nothing to compare it against.
