Website-reported autofeeds let merchants sync local inventory via Google Tag Manager without a local feed

Merchant Center added website-reported autofeeds: when a shopper checks in-store availability on a product page, a GTM tag captures availability, store code and price and syncs it to Merchant Center. It works for local inventory ads and free local listings without a dedicated local product inventory feed.

• Requirements: a working Google Tag Manager setup, product pages with store selection, and the ability to pass inventory data through GTM.
• Removes the need for a separate local product inventory feed for retailers with physical stores and an active e-commerce site.
