For two decades, the most-watched metric in marketing was "branded search volume." How many people typed your company's name into Google?
That metric is dying. Not because people stopped caring about brands (they care more than ever) but because they stopped typing brand names into Google. They type them into ChatGPT, ask Claude for a comparison, or just describe what they want and let the model figure it out. To understand how those AI engines behave differently, read our ChatGPT vs Perplexity vs Gemini brand citation comparison.
In the categories we track, branded search volume has declined even as overall brand awareness has grown: a directional trend consistent with the shift toward AI-assisted discovery.
The replacement metric is what we call AI Voice Share: how often your brand is mentioned, in what context, and with what sentiment, when AI assistants answer category-defining questions. That's what AI visibility measures, and it's what Pondral tracks, using a five-factor scoring rubric built for reproducibility and transparency.
