Amazon High‑Demand Niche Finder
Amazon High‑Demand Niche Finder
Find High‑Demand / Low‑Competition niches using BSR, reviews, price spread, and top‑of‑page density. Works offline with CSV paste. Optional Keepa/PAAPI later.
1) Input
Mode A: CSV / Paste
Target marketplace
Amazon.in (India)
Amazon.com (US)
Amazon.co.uk (UK)
Amazon.de (Germany)
Seed keyword (reference)
Paste data (CSV or table)
Columns accepted (order flexible): ASIN, BSR, Reviews, Price, Category. One product per line.
Analyze top N rows
Analyze Niche
Optional: Upload CSV
Mode B (Optional): API Setup
• For automation, add a small Node backend (server.js) with Keepa API (sales rank history, drops/month) and/or Amazon PA‑API 5 (title, price, reviews). Replace fetchFromBackend() to pull live ASIN data by keyword.
• Accuracy tip: use Keepa sales rank drops per month as sales proxy, median BSR for top N, and review count + rating for competition.

Note: No scraping. For best accuracy, connect Keepa/PA‑API on a backend. This front‑end computes conservative proxies from your CSV (BSR, reviews, price).
