Harpd Rank Research

AI market index

The AI Market Index is the cross-category view of the entire Harpd Rank board. Where the segment indexes track one product market, this report measures the board as a whole: how many products compete, how Rank Points are distributed across categories, which categories gained or lost share, and which products moved the most in the closed month. Every figure comes from the closed monthly archive snapshot, so the report is reproducible and never drifts after publication.

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

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.
