Duplicate Check
機能
Exact Duplicate Detection
AI finds products with identical or near-identical descriptions — copy-pasted content that Google penalizes.
Similarity Percentage
See how similar two descriptions are: "Product A and Product B are 87% similar" — with highlighted overlapping text.
Cross-Catalog Check
Check for duplicates across different catalogs and stores — prevent the same description appearing on multiple platforms.
Uniqueness Score
Every product gets a uniqueness score. Filter by "least unique" to find and fix the worst offenders first.
使い方
Select Scope
Check within a catalog, across catalogs, or against external URLs.
Run Duplicate Scan
AI compares all descriptions and calculates similarity percentages.
Review & Rewrite
See duplicate pairs, similarity scores, and one-click rewrite to make each unique.
