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.
What Are Split Reviews?
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:
- Less social proof means lower conversions
- Lower star averages on individual ASINs
- Competitors get an edge, even if your product is superior
What Are Orphaned ASINs?
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:
- The ASIN isn’t searchable with keywords that used to work
- Reviews are missing
- It looks like a brand-new listing, despite having been live for months or years
- Performance metrics drop without explanation
The Real-World Impact
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:
- Sudden drop in conversion rates
- Decreased PPC performance due to lost relevance
- Declining organic rankings
- Misleading performance data
How to Spot These Issues
Unless you’re checking each ASIN regularly, these issues often go undetected. Most sellers don’t notice until sales dip—or Amazon flags the listing. Here's what to look for:
- Drop in average star rating without new reviews
- Reviews not syncing across variations
- Listing no longer shows in search results
- Missing Q&A or product images
How to Fix Split Reviews & Orphaned ASINs
Fixing these issues often requires surgical-level intervention:
- Catalog rebuild or variation rematch via flat files
- Case escalations to the Catalog or Brand Registry teams
- Requesting review aggregation when policies allow
- Using a monitoring service to detect and alert you early
It’s critical to get expert help if you're unsure—missteps in variation setup or support communication can lock your catalog in a broken state.
