| Signal | Weight | Score | What it measures | Car Audio |
| --- | --- | --- | --- | --- |
| Retrieval grounding | 26 | Does not apply | Whether you appear in the ranked results AI retrieves and cites: AI-Overview citations, organic top-10 for your money queries, and the Bing index ChatGPT leans on. |  |
| Off-property attestation | 20 | 40 | Volume and consistency of what others say about you: YouTube mentions, branded web mentions, third-party “best-of” lists. The cause of retrievability. | Poor |
| AI visibility | 14 | 14 | Whether ChatGPT, Gemini, Perplexity, and AI Overviews name you, and whether they name you for the right service. | Poor |
| Reviews & response | 12 | 85 | The star average is only one input. We also read volume, velocity, the specificity of review language, and response cadence. Specific reviews are what AI quotes verbatim. | Good |
| Backlink & citation authority | 8 | Does not apply | Domain authority and editorial quality of the sources that attest to you. |  |
| Google Business Profile | 8 | 78 | Required and recommended fields; update cadence. The listing AI pulls from first. | Good |
| Speed & mobile | 7 | Does not apply | Core Web Vitals at the 75th percentile, on a real phone. |  |
