Harpd Rank Research

AI tools trends

Trends are only visible when two closed snapshots are compared. This report diffs the month's archive against the previous month: which products moved up, which slipped, which categories gained share and which products entered the board for the first time. All deltas are computed from Harpd Rank archive data, not estimated.

Built from closed monthly snapshots of Harpd Rank. Rank Points are paid promotional placement, not an editorial quality score.

Method

Each report diffs two closed monthly archive snapshots: top products by final monthly position, per-product movement, category shares and new entrants. Snapshot data is immutable and publicly downloadable (CC BY 4.0).

Frequently asked questions

Why does this family have reports only for some months?

Reports are generated only for closed months whose snapshot contains at least five ranked products in this family's category scope. Earlier or thinner months produce no report rather than a hollow page.

How is the ranking computed?

By Harpd Rank Points: one completed Credit spend creates one permanent Rank Point. The monthly board orders by points earned in the UTC month; positions in reports are overall monthly board positions, not category-relative.
