Connect BigCommerce to Google Shopping

My BigCommerce catalogue still has zero presence on Google Shopping because it has never been linked to Google. I also have no Google Merchant Center or Google Ads account yet, so you will be starting from a clean slate.

Your task is to create those accounts, verify my store, and build an automated product feed that pushes every item in my inventory—nothing is excluded—into Google Merchant Center. I need the data mapped correctly so titles, prices, images, GTIN/SKU, and stock levels meet Google’s policies and refresh automatically. Once the feed is live, I expect to see the products show in the Shopping tab when I search relevant keywords or SKUs.

Deliverables
• Verified Google Merchant Center (and Ads, if required) connected to my BigCommerce store
• Continuous feed pulling all store products at least daily
• All products approved in Merchant Center with no critical errors
• A short walkthrough explaining how to monitor and maintain the feed

Acceptance criteria: at least a sample of my items must appear in U.S. Google Shopping results without disapprovals, and I should understand how to keep everything updated after hand-off.
