ChatGPT share of voice tracking
ChatGPT share of voice combines linked and unlinked appearances across n logged-out samples, returned with a confidence interval. Around 900 million weekly users sit behind this number.
How it renders
Derived from mentions and citations across the sample set.
Sampling
This is the field where n matters most. At n=1 the metric is noise; at n=30 the interval is typically tight enough to defend in a client report.

- How stable is ChatGPT share between runs?
- Less stable than the Google surfaces on recommendation prompts. Thirty samples is our floor and volatility scoring flags the prompts that need more.
- Can I split linked from unlinked share?
- Yes. Both are returned separately as well as combined.
