Why product taxonomy matters
The taxonomy is invisible until it’s wrong: navigation, filters, search, feeds, and analytics all inherit its structure. A shopper who can’t find the category, a filter with no attribute behind it, a feed rejected for missing classification, all trace back here.
What a working taxonomy has
- Categories shaped by how shoppers look, not internal org charts
- Consistent attributes per category: size, material, use, compatibility
- One home per product, with cross-listing done deliberately
- Mapping to marketplace and feed category standards
Questions
How deep should category levels go?
As deep as shoppers actually narrow, usually two or three levels, with filters doing the fine slicing. Ten-deep trees hide products; attributes plus filters find them.
When should a taxonomy be restructured?
When search logs and dead-end navigation show shoppers thinking differently than the tree: rename and regroup to their vocabulary, with redirects preserving the SEO of moved categories.
