Three sourcing
questions.
What CategoryRank answers, who it's for, and where to start.
Which categories have the widest vocabulary gap between AI, distributors, and OEMs — and where does that gap mean a real arbitrage window?
The category browser ranks every category by fragmentation. The most-fragmented categories are the ones where the ecosystem disagrees most — which means the brands buyers find through AI aren't the same ones in the distributor catalogs. That gap is your buy.
Open the fragmentation leaderboard →Which categories are concentrated on too few manufacturers, in too few countries, in fab-versus-assembly footprints I can't replace?
Per-category manufacturing footprint shows facility counts, geographic concentration (CN / US / DE / TW / JP), and facility-type mix (fab / assembly / test). When a category leans 75% assembly in two countries, that's a single-disruption risk you can quantify.
See power-supplies geographic concentration →How does AI describe my product category — and does my own product page use the same vocabulary buyers see in their AI shelf?
The form histogram on every category page shows the top alias forms across AI, OEM, distributor, and aggregator vantages. When your product page taxonomy doesn't match the dominant AI form, your brand drops out of the AI shelf for that category — even if you're the strongest competitor in it.
