Error Solution

To resolve the "Error 18109: Duplicate product detail pages" on Amazon, follow these steps:

  1. Review Amazon’s Listing Guidelines:
    • Familiarize yourself with Amazon’s guidelines regarding duplicate listings. Understand what constitutes a duplicate listing and the criteria Amazon uses to identify them.
  2. Identify the Existing ASIN:
    • Use Amazon’s search tools to find existing products that closely match the details of your submission. Identify the ASIN(s) that are potentially causing the duplicate listing issue.
  3. Compare Product Details:
    • Carefully compare your product details (title, description, images, attributes) with those of the existing ASIN(s). Identify the similarities and differences.
  4. Determine Listing Strategy:
    • If the product is genuinely the same as an existing ASIN, consider adding your offer to the existing ASIN rather than creating a new listing.
    • If the product has distinct differences, update the product details to clearly highlight these differences.
  5. Update Product Details:
    • Revise the product title, description, images, and attributes to differentiate your listing from the existing ASIN(s). Ensure that your product listing accurately reflects any unique features or variations.
    • Use original and high-quality images that clearly showcase your product. Avoid using stock images that may be used by other sellers.
