What this benchmark means
- Creator video adoption is early: category leaders carry a median of just 1 creator video. A steady creator content pipeline is one of the fastest ways to out-content this category's top sellers.
- The leaders are entrenched — a median of 1,020 reviews at 4.7 stars. Content parity with this benchmark is the price of entry; review volume takes longer to build.
