Definition
AI share-of-voice (LLM SoV) is the percentage of LLM-generated answers (from ChatGPT, Claude, Perplexity, Gemini, etc.) for category-relevant queries that mention or cite a given brand. It is the LLM-channel analog of organic-search share-of-voice metrics.
In Depth
As LLM-generated answers absorb top-of-funnel queries traditionally answered by Google's organic SERP and paid ads, the metric shifted accordingly. By 2026, marketers track AI SoV alongside organic SoV. Measurement requires polling each LLM's API (or product) for the same buyer-intent queries on a cadence and counting brand mentions/citations weighted by position. Honest constraint: LLM responses are non-deterministic across runs; a single-shot poll is noisy. Production AI SoV trackers run 3-5 polls per query per LLM and average. The leading-indicator pair: AI Overview citations from Google SERP + Reddit thread density for the same topic precede LLM SoV shifts in many categories.
Example Usage
An r/DigitalMarketing post asked if marketers were stopping Google Ads campaigns due to LLMs. The implicit need: a metric that quantifies LLM-channel share so the ads-vs-AEO budget shift can be data-driven. AI SoV is that metric.
