Seller Name [seller_name] Field for Product Feed

Required for Display in ChatGPT Listings

The seller_name attribute identifies the merchant or store name associated with each product offer.
It is displayed to users in ChatGPT and partner shopping experiences to indicate who sells or fulfills the product.

When to use

This field is required for all offers listed in ChatGPT’s product experiences.
It ensures clear attribution and helps differentiate multiple sellers for the same product.

• [seller_name] should:
  • Match your brand or store name as users recognize it.
  • Remain consistent across all feeds and marketplaces.
  • Avoid unnecessary terms such as “official” or “best prices”.
  • Be limited to 70 characters or fewer.

Format

• Type: String (UTF-8 text)
• Character limit: 70
• Repeated field: No
• Schema.org property: Offer.seller

Examples:

Relationship with external_seller_id (Google)

In Google Merchant Center, the external_seller_id attribute serves as a technical identifier for the seller,
while seller_name provides the public-facing display name shown to users.

In SharpFeed, only seller_name is required for visibility in ChatGPT.
You may optionally keep a technical seller reference internally for synchronization with Google feeds.

Minimum requirements

Note: A missing or generic seller name may prevent your offers from being displayed in ChatGPT.

• Use your actual merchant name (as displayed to customers).
• Keep the name under 70 characters.
• Maintain consistency across your feeds and platforms.
• Don’t use promotional or descriptive text (“Fast Shipping Store”).
• Don’t use placeholder names or numeric IDs.

SEO / AI Tip

A consistent and recognizable seller_name improves brand trust in ChatGPT listings.
It also helps maintain accurate seller attribution across multiple offers, increasing credibility and click-through rates.
