How to measure brand framing and competitive answer space without letting noise or hallucinated competitors distort the result.
A mention can be positive, neutral, or negative
Brand framing adds context that presence alone misses. Exact supporting spans should be preserved so classification can be reviewed rather than represented only by an opaque score.
Sentiment is much noisier than mention
In Kumar’s repeated unbranded observations, mention flipped in 6.8% of cells while sentiment flipped in 45.5%. The exact rates belong to that dataset, but they show why the two signals should not be mixed blindly.
Report stable coverage and volatile framing separately before building any composite.
Share of Voice measures competitive answer space
AI Share of Voice divides target-brand mentions by target plus competitor mentions. It shows how much of the available recommendation space the brand captures within a defined panel.
The competitor denominator must be controlled
One-off hallucinated brand names can artificially dilute Share of Voice. Kumar counts competitors that recur or resolve to a real domain, illustrating a general rule: every KPI is only as meaningful as its denominator.
Competitor inclusion and entity resolution rules should be documented.
Questions about this topic
Should sentiment be combined with Mention Rate?+
Usually not before reporting both separately. Sentiment can be substantially noisier and destabilize a composite score.
What is AI Share of Voice?+
It is the target brand’s share of mentions relative to the target plus a defined competitor set.
Why does the competitor denominator matter?+
Hallucinated, misspelled, or one-off entities can distort the competitive share if included without validation.
How should sentiment be audited?+
Store positive, neutral, or negative labels alongside the exact text spans and review uncertain or high-impact cases.
