Marketplace Management

Selling on Trendyol and Hepsiburada does not end when the listing goes live. Both your visibility and your risk of suspension come down largely to two things: your seller score and the accuracy of your catalogue record. This section covers both in detail.

The seller score article explains the 11 metrics behind the score one by one, with their weights and colour bands. It shows how violation point tiers work, at which threshold operational suspension is triggered, and what Hepsiburada calculates differently. Seeing which of dispatch time, cancellation rate or question response speed actually carries weight changes what you prioritise day to day.

The catalogue management article deals with the mistakes you cannot undo after approval: the barcode rule, the difference between slicer and varianter, the 100-variant limit, and the officially documented buybox factors. The API limit change that took effect on 14 September 2026 is covered here as well.

Most marketplace operating errors are made during the initial setup and only noticed months later as lost revenue. The material here is aimed at getting that setup right and auditing a catalogue that is already live.
