Harpd Rank Research

Monthly research reports

Each report below is computed from a closed monthly snapshot of Harpd Rank — top products, rank movement, category breakdown and new entrants. Reports are published only when a UTC month has closed with enough ranked products, so every URL that resolves here carries real data behind it.

Rank Points are paid promotional placement, not an editorial quality score. Methodology and limitations are stated on every report.

Why it matters

These reports turn a live promotional leaderboard into a reproducible, point-in-time research record. Because each report is built from a closed snapshot with a stated methodology, you can cite a specific month's market structure instead of relying on a moving real-time board.

Limitations

  • Reports are computed only from products submitted to Harpd Rank; periods or categories with too few ranked products are not published.
  • Each report is a closed monthly snapshot — it describes that period, not the current live board.
  • Rank Points are promotional placement, not an editorial quality score.

Method

Reports diff closed monthly archive snapshots of the Harpd Rank board. A snapshot is immutable once the UTC month closes; movement, new entrants and category shares are computed between adjacent snapshots — never estimated. The full methodology, dataset endpoints and limitations are documented on each report.

Frequently asked questions

When is a new research report published?

Monthly, but only when the closed month's snapshot contains enough ranked products in the report's category scope. Months without sufficient data produce no report and no URL — nothing is generated speculatively.

Where does the data come from?

From Harpd Rank, the public product leaderboard: closed monthly snapshots are immutable and mirrored at /data/rank-history.json. Every report links the exact snapshot endpoints used.

Can I reuse the data?

Yes — the datasets are published under CC BY 4.0 with attribution to Harpd Rank.
