- In Merchant Center → Your business (left nav) → Shipping and returns: add shipping policies (cost, speed, countries). You can create multiple shipping policies (up to limits per country). Google Help+1

4) Prepare your product feed (choose a method)
You have several ways to provide product data — choose whichever fits your store size and tech comfort:
- Google Sheets feed (good for small catalogs).
- Upload a file (CSV/TSV or XML). Files up to 4 GB allowed; manual re-upload needed when you change data. Google Help
- Content API (developers — automatic, programmatic).
- Platform integration / channel (Shopify, WooCommerce, BigCommerce apps that sync products automatically). Google Help+1
Required product attributes (core): id, title, description, link, image_link, price, availability — many more attributes are recommended (brand, GTIN, MPN, condition). Follow Google’s Product Data Specification. Google Help+1
