Each metric has its own page: definition, calculation, why it matters, and what to do when it moves. The eBay connector covers the seller-standards posture eBay sellers actually need to track - *Defect Rate*, *Seller Standards Level*, *Open INR Cases*, *Listings Missing Attributes* - alongside revenue and listing-health KPIs. The **Nerve Centre** tracks 50 KPI pulses for eBay stores in the Vortex IQ **AI OS** catalogue. The cross-platform cards fuse eBay with Amazon (*Catalogue Drift vs Amazon*, *Amazon Top SKUs Missing on eBay*, *eBay vs Amazon Revenue Share*) so multi-marketplace operators see the joined picture. **Vortex Mind** investigates when standards drop or revenue dips; **Ask Viq™** lets you ask in plain English with citations back to the card. | Card | Metrics type | Category | Chart | |
