Why it matters
This figure is computed from a first-party Harpd dataset and published with its own source, method and data date — so it can be checked and quoted rather than taken on trust.
Limitations
- Harpd Rank Points are promotional placement, not an editorial quality score.
- Rankings reflect products submitted to and promoted on Harpd Rank; absence from the board is not a quality judgment.
- Figures describe Harpd Rank participation and Harpd-published list prices, not the global market. Quote them with the data date shown above.
