Delivery Estimate [delivery_estimate] Field for Product Feed

Optional but Recommended for Transparency in ChatGPT

The delivery_estimate attribute specifies the expected delivery or arrival date for a product.
Providing this field improves user trust and conversion by setting clear expectations on shipping times, especially for preorders or backordered items.

When to use

Use this field when you can provide a reliable estimated delivery date for your product.
It’s especially useful for:

• Products with variable fulfillment or shipping times.

• Preorders or custom-made items.

• Items temporarily out of stock but available for future delivery.

• [delivery_estimate] should:

  • Follow the ISO 8601 date format (YYYY-MM-DD)
  • Represent a future date relative to the feed upload date
  • Reflect realistic shipping conditions

Format

• Type: Date
• Format: ISO 8601 (YYYY-MM-DD)

Minimum requirements

Note: The date must be in the future relative to when the feed is processed.

• Use the ISO format YYYY-MM-DD.
• Ensure the date represents an estimated delivery, not the order or shipping date.
• Only include this field when a reliable estimate is available.
• Don’t use past dates.
• Don’t include text like “1 week” or “soon” — only valid dates.
