The stuff your phone gets asked.
Plain-English explainers on fitment data, eBay compatibility, feeds and search for people who sell car parts. Written once, so we can stop repeating ourselves — and so you can send them to your team.
What is a K-Type?
The vehicle ID every UK parts seller should understand: where it comes from, how reg lookup uses it, how it differs from ePID and ACES, and the six mistakes that cause "doesn't fit" returns.
K-Type to ePID: why your website and eBay disagree
Two vehicle catalogues that were never designed to talk to each other, the wrong fix everyone tries first, and how to build a mapping that keeps both channels honest.
Google Shopping for car parts: getting fitment into the feed
Google has no My Garage. The title, description, product_detail attributes, categories and identifiers are the only way a part shows for a vehicle search — here's how to structure them.
Supersessions and cross-references: keeping old part numbers selling
Old numbers are the highest-intent searches you get. Aliases, forgiving search, what to do with the old URL, and how to cross-reference other brands honestly.
