## Method, in short

Source: data observed and catalogued by First Answer. Each week, we measure by model the share of answers that cite youtube.com among their sources and compare it with the previous week. A change is flagged as significant only when it exceeds the 95% margin and is at least 1 pp. Weeks with a smaller-than-usual base are flagged and left out of the comparison.

## Limitations

The index measures what First Answer's base observes, not every search made on the models. We do not disclose volumes, questions, topics, categories, brands, channels or clients; only aggregate measures by model. Claude is not included in this series. Explanations under Events come from external sources and state how confirmed they are.
