What is a condition mismatch?

The condition attribute tells Google whether a product is new, refurbished, or used. A condition mismatch happens when the value in your feed contradicts what shoppers see on your landing page.

Google accepts exactly three values: new, refurbished, used. There is no “like new,” “open box,” or “excellent.”

How Google detects condition mismatches

  • Schema.org structured data — The itemCondition property in JSON-LD. Most authoritative signal.

  • Visible page content — Text describing condition: “Certified Refurbished,” “Used — Good Condition,” “Brand New.”

  • Page title and description — Words like “refurbished,” “pre-owned,” “renewed,” “open box.”

  • Category context — A product in a “Refurbished Electronics” section sends a strong signal.

The three accepted values

new

Products in original packaging, never used.

refurbished

Professionally restored to working order. Includes manufacturer-certified refurbished, professionally cleaned/tested used items, inspected open-box returns. Open-box items not professionally inspected should be classified as “used.”

used

Previously owned or used products. Includes customer returns, pre-owned items sold as-is, items with any signs of use.

Edge cases

  • “Like new” → use used. Communicate excellent condition in description.

  • Amazon Renewed / Apple Certified Refurbished → refurbished

  • Floor models / display units → used (or refurbished if professionally restored)

  • Vintage or antique items → used

Step-by-step fix workflow

  • Filter Diagnostics by condition-related disapprovals.

  • For each product, visit the landing page. Use Google’s Rich Results Test to see what itemCondition Google reads.

  • Determine actual condition (the ground truth).

  • Update condition in your feed to match.

  • Update structured data: NewCondition, RefurbishedCondition, or UsedCondition.

  • Re-fetch your feed and verify with Rich Results Test.

Correct schema.org JSON-LD

{
  "@type": "Product",
  "name": "MacBook Pro 14-inch (2023)",
  "offers": {
    "@type": "Offer",
    "price": "1299.00",
    "priceCurrency": "USD",
    "itemCondition": "https://schema.org/RefurbishedCondition"
  }
}

Prevention

  • Never set a default condition of “new” at the feed level — require explicit values from your inventory system

  • Keep condition in sync across feed, structured data, and page text

  • Audit newly added inventory before feed upload
