How Reverse ASIN Works

Title & Bullet Analysis

KDP Radar fetches the full product page for each ASIN and extracts meaningful keyword phrases from the title and feature bullets.

Search Result Mining

Seed terms are searched on Amazon Books, and the resulting titles are analyzed for additional keyword phrases and combinations.

Frequency-Based Scoring

Keywords appearing across multiple seed searches get higher relevance scores. The most frequently occurring terms surface first.

Multi-ASIN Analysis

Analyze up to 5 ASINs simultaneously. Cross-reference keywords across competitors to find the terms that matter most in your niche.

Word Cloud Visualization

See the most common keyword terms rendered as a word cloud, making it easy to spot dominant themes in your competitor landscape.
