Navigating online marketplaces requires more than luck; it demands strategy. The EastMallBuy spreadsheet method is a systematic approach to evaluating seller quality, turning subjective impressions into objective data. This guide explains how to leverage this powerful tool.

The Core Metrics: What to Track

The foundation of a reliable seller database lies in consistently tracking three key performance indicators (KPIs):

  • Product Condition Accuracy:
  • Refund/Issue Frequency:
  • QC (Quality Control) Approval Rate:

Structuring Your Spreadsheet

Organize your data to make analysis straightforward. A simple table structure works best:

Store Name Order Date Product as Described? (Y/N) Refund Required? (Y/N) QC Passed? (Y/N) Notes & Comments
ExampleStore123 2023-10-15 Y N Y Item packaging was excellent.
ExampleStore123 2023-11-02 N Y N Color was different from photos.

Over time, you can use formulas to calculate a Trust Score
