## Summary

Ahrefs outlines a method for measuring AI share of voice (AI SOV), the proportion of AI‑generated responses that mention a brand compared with tracked competitors. The metric is calculated by dividing the number of responses that cite a brand by the total responses that cite any tracked brand, then weighting each prompt by its AI‑adjusted volume – the monthly Google search volume multiplied by a platform‑specific traffic ratio. Ahrefs uses ratios of 0.115 for ChatGPT, 0.011 for Gemini, and 0.01 for Perplexity, so a 20,000‑search keyword translates to 2,300 estimated impressions on ChatGPT and 220 on Gemini.

The guide shows how Brand Radar can generate AI SOV scores instantly from a broad index of pre‑collected AI responses or from custom‑tracked prompts that collect data over time. Each check equals one prompt execution on a chosen AI assistant in a specific location. Marketers can filter by platform, view underlying responses, and save reports for consistent, reproducible comparisons. The article stresses that AI SOV reflects visibility, not outcomes, and that changes in prompts, competitors, or platforms can alter percentages, so trends should be interpreted carefully.

## Key points
