ChatGPT
Capture the returned answer, brand mention state, first-mention prominence and observed citations for the prompts you track.
Measurement contract
Measure Share of Voice without mixing the score
SOV Tracker treats every scan as a dated sample. Raw Share of Voice is the competitor-relative percentage; Visibility Score is a separate prominence/visibility score. You can inspect the evidence behind both instead of reading one blended number.
Five paid-plan engines, one measurement contract
Paid plans cover ChatGPT + AI Overviews + Gemini + Perplexity + Claude. Each result keeps engine identity, answer evidence and measurement state explicit.
Claude
Compare dated Claude answers with the same tracked brand and competitor set instead of treating one response as a permanent ranking.
Gemini
Track whether your brand and configured competitors appear in Gemini responses and preserve the answer evidence behind the measurement.
Perplexity
Measure mentions and retain source URLs when Perplexity exposes or returns them in the evidence available to the scan.
AI Overviews
Track dated Google AI Overview observations as another engine-specific sample, with the same measured/not-measured rules.
Two metrics, two meanings
The product now keeps percentage share, visibility/prominence and measurement availability separate across customer surfaces.
Raw Share of Voice
SOV is the target brand's valid mention count divided by valid mentions for the target brand plus the configured competitor set. It is a percentage share; no position bonus is mixed into it. We do not weight raw SOV by engine market share, prompt popularity, or prompt volume.
Separate Visibility Score
Visibility Score is a separate 0–100 product score for prominence/visibility. Keeping it separate prevents a position-weighted score from being mistaken for market share.
Competitor-relative evidence
SOV is only shown when a competitor universe exists. If the provider fails or there is no comparison universe, the product says not measured instead of manufacturing 0 or 100.
Frequently Asked Questions
How many competitors can I track?
Free supports 3, Starter 10, Pro 25 and Agency 50 competitors.
What exactly is AI Share of Voice?
AI Share of Voice is the percentage of valid mentions belonging to your brand within the configured comparison set: your brand mentions divided by your brand plus competitor mentions. It measures share, not prominence.
What is Visibility Score?
Visibility Score is a separate 0–100 score used to describe how visible or prominent the brand is in returned answers. Position/prominence signals belong here, not inside the SOV percentage.
When is SOV not measured?
If there is no configured competitor universe, the comparison counts are invalid, or the provider response is unavailable, SOV is reported as not measured. If the configured comparison universe is measured and nobody is mentioned, that is a measured 0%, not a missing measurement.
Which engines are included?
The no-signup Free Scan checks ChatGPT. Paid plans include ChatGPT + AI Overviews + Gemini + Perplexity + Claude. Engine scope is derived from the plan contract rather than a hard-coded marketing exception.
How often can I refresh the measurement?
Free currently has a 4-scan monthly ceiling. Starter, Pro and Agency each have a 35-scan monthly ceiling. One scan refreshes the active tracked keywords across the engines included in the plan. Scans are started manually. Automated background scanning is not currently available.
