If your ASIN isn’t getting the reviews it deserves—or worse, if your ratings are mysteriously tanking—there’s a good chance you’re dealing with Split Reviews or an Orphaned ASIN. These hidden catalog issues can quietly cripple your conversions and go unnoticed for months unless you're actively monitoring them.
Split Reviews happen when reviews for a product no longer combine under one listing. This usually affects parent-child ASIN relationships (like variations of color or size) and often occurs after catalog changes, merges, or backend listing edits. Instead of all your reviews being shared across variations, they split off and show fewer reviews on each variation, making your listings look less trustworthy or underperforming to shoppers.
Why it matters:
An Orphaned ASIN is a child ASIN that’s been detached from its parent or lost its connection in Amazon’s system. It no longer inherits reviews, Q&A, or SEO power from the parent listing. This usually happens after a variation removal, improper flat file uploads, or merge errors.
Symptoms of an Orphaned ASIN:
Imagine this: you’ve got 2,000 reviews spread across five variations. A backend error splits them, and now each child ASIN shows only 400 reviews—or worse, some show none (as is a common issue). You’ve effectively lost your hard-earned social proof and damaged your conversion rate. Or your best-selling variant goes missing from search results, and no one knows why.
Sellers experiencing these issues often see:
