New! Website‑reported Autofeeds For Google Merchant Center Auto‑import In‑Store Inventory

Google’s Website-reported Autofeeds offer a streamlined method to automatically import your in-store inventory data into Google Merchant Center—no extra feed files required.

How It Works

  1. Customer action: A user checks in-store availability on your site (e.g., clicks a “Check Availability” button).
  2. Trigger GTM tag: A custom Google Tag Manager tag fires.
  3. Data captured: Tag collects key info:
    • Merchant Center ID
    • Product ID
    • Availability (in stock/out of stock)
    • Store codes
    • Price
    • Country & language
  4. Data sent to Google: Google matches and updates listings in Merchant Center.
  5. Display everywhere: Local availability appears in Shopping ads, free listings, and on Google Maps when shoppers search nearby.

🛠 Requirements & Setup

From Google’s documentation (support.google.com):

  • Website readiness: Product pages must support in-store availability.
  • Google Tag Manager: Required to deploy the “Google Inventory Collector” tag.
  • Technical resources: You or your developer must configure GTM variables and triggers (e.g., checkout interaction or button click).

Implementation steps:

  1. In Merchant Center, enable local inventory ads or free local listings.
  2. Choose page type:
    • Product pages with store availability
    • Store-specific product pages including price
  3. In GTM:
    • Create a Google Inventory Collector tag
    • Add Merchant ID and relevant variables (item ID, store code, etc.)
    • Trigger on the appropriate user action
  4. Publish the change after testing in Preview mode.

🌐 Compare with Other Local Inventory Methods

Google offers five ways to add local store inventory to Merchant Center via the Additional sources tab:

  1. Ship to store: Use [pickup_SLA] and [pickup_method] attributes for items shipped to store.
  2. Auto‑add from online store (classic crawling): Google scrapes your site daily for store availability—simple, but often limited to top products and subject to crawling delays.
  3. Website‑reported Autofeeds (this new method): Real-time updates via GTM tags when users check availability.
  4. Local inventory feed file: You upload a daily feed with full store-level data.
  5. Content API: Full programmatic control over inventory data.
  6. Local data provider: Third-party manages inventory updates on your behalf.

✅ Pros and Cons

✅ Advantages of Autofeeds:

  • Removes the need for a separate local inventory feed
  • Near real-time updates when customers check availability
  • Syncs data seamlessly with Merchant Center

⚠️ Considerations:

  • Requires GTM and coding capability
  • Limited to products that trigger tag events
  • Potential issues with lagging Google crawling

📝 Who It’s For

This method suits:

  • Midsize to large merchants
  • Sites with dedicated dev resources
  • Platforms like Shopify that allow custom GTM integration
  • Use cases where real-time stock visibility is critical

Smaller sellers or those relying on daily batch updates may find feed files or Content API easier to manage.

🛠 Implementation Tips

  1. Select your page experience: basic vs. store‑specific.
  2. Deploy GTM tags: include all required data fields.
  3. Test thoroughly: use GTM’s Preview mode and check Merchant Center’s tag diagnostics.
  4. Monitor crawling frequency: review “last crawled” under Product Details > Additional Details in Merchant Center.
  5. Check coverage: ensure tags fire consistently on every product interaction.
