Fitment is the question space
Auto-parts buyers ask fitment questions: "does this fit a 2019 F-150", "OEM-equivalent brake pads for W205 C-Class". Engines answer from whoever publishes structured, complete compatibility data. A parts brand without machine-readable fitment tables is invisible to the category's highest-intent queries — no amount of brand content substitutes.
The trust layer
Counterfeit anxiety dominates the category's reputation questions. Publish: certification facts (IATF 16949, E-mark, DOT as applicable), warranty terms in quotable lines, and anti-counterfeit verification (serial checks, authorized-channel lists). Engines answer "is [brand] legit auto parts" from exactly this material.

Fitment aggregators and parts directories, marketplace reputation (Amazon/eBay Motors), forum presence in model-specific communities (where the enthusiast verdict forms and engines read it), and trade distribution press.
