Why it matters
A figure is only citable when a reader can check where it came from. This page fixes the dataset, the method and the data date next to the claim itself, so a journalist, researcher or answer engine can quote the number without asking anyone for the source.
Limitations
- Mechanics describe how the Harpd ranking system works, not how any third-party ranking system works.
- Rules in force are the ones published on the Rank rules page at the stated date; later changes apply to later periods.
