BSR Tracker: monitoring sales rank across thousands of listings at once.
A multi-ASIN marketplace tracking tool built for a real book-title catalogue — replacing manual, one-by-one listing checks with a single live view.
What we built
A secure, authenticated tool that pulls live sales-rank and listing data for multiple product ASINs automatically, with full Excel import/export so it plugs into an existing reporting workflow rather than replacing it.
Manual, one-by-one checks don't scale past a handful of listings.
The client needed to monitor sales-rank and listing performance across a real catalogue of thousands of book titles. Checking each listing individually — the only option available — was slow, inconsistent, and effectively impossible to do reliably at that scale.
Before: manual lookups, one listing at a time.
There was no batch tool — each ASIN had to be checked individually, manually, with no way to see rank movement over time without doing the same manual check repeatedly. At catalogue scale, this made consistent monitoring effectively impossible.
A batch tracking tool with secure access and live data.
The tool pulls live sales-rank and listing data for multiple ASINs in a single batch view, with rank-change indicators showing movement at a glance. Secure authenticated login protects access, and full Excel import/export means the data plugs directly into existing reporting rather than requiring a new workflow.

What the system actually does.
Multi-ASIN batch tracking
Monitor an entire catalogue in one view instead of checking listings one at a time.
Automated data refresh
Rank and listing data pulls automatically, without a manual re-check.
Rank-change indicators
See at a glance whether a listing moved up or down since the last check.
Secure authenticated access
Login-protected, not an open tool anyone can access.
Excel import/export
Plugs directly into an existing spreadsheet-based reporting workflow.
Designed to turn a slow manual process into minutes.
The tool replaces individual manual listing checks with a single batch view covering the full catalogue. It was built and delivered for ongoing marketplace monitoring. We haven't published specific time-saved figures for this project — happy to walk through how we'd think about measuring impact for your own catalogue on a call.
