First-party Rank data
Rank history
Completed Monthly and Weekly results are preserved as immutable period snapshots. Reports become indexable only after at least five products rank.
Quick answer
What is the Harpd Rank history archive?
The Harpd Rank history archive preserves every completed Monthly and Weekly leaderboard period as an immutable snapshot. Once a UTC period closes, its final positions are frozen and published as a permanent, citable record; a period only becomes indexable after at least five products have ranked.

Why it matters
A live leaderboard is always moving, so it cannot serve as a stable citation. The history archive freezes each completed period so a figure quoted from a specific month or week stays true forever — the foundation for the citable monthly reports and data drops.
Limitations
- A period is archived and indexed only after at least five products have ranked; thinner periods are not published.
- Snapshots record positions at period close only — not movement within the period.
- Rank Points in any archive are paid promotional placement, not an editorial quality score.
