Marketing executives love “Share of Voice” (SOV). It was an easy metric: “We possess 30% of the visibility on the first page of Google for these keywords.” This meant if there were 10 links and 4 ads, you showed up in 4 spots.

Generated Share of Voice (GSV) is a different beast. It is a “winner-take-all” metric.

The Collapse of Real Estate

In a Generative Search Experience (SGE / AI Overview), there is usually only one answer generated. That answer might contain 3-4 citations.

You cannot improve what you cannot measure. But how do you measure visibility in a chat box? Traditional rank trackers (SEMrush, Ahrefs) track positions on a SERP. They do not track mentions in a generated paragraph.

The New Tool Stack

We are building tools to probe LLMs with thousands of permutations of a query to calculate Generated Share of Voice (GSV).

The Methodology

1. Define a Query Set: “Best CRM,” “CRM software,” “Sales tools.”
2. Permutation: Use an LLM to generate 100 variations of these questions (“What CRM should I use if I am a startup?”).
3. Probe: Run these 100 queries across GPT-4, Claude 3.5, and Gemini via API.
4. Extraction: Parse the text output. Extract Named Entities (NER).
5. Frequency Analysis: Calculate the frequency of your brand’s appearance vs. competitors.

The “Share of Sentiment”

It is not just about frequency. It is about sentiment.
