Google Merchant Center integration

What Google Merchant Center is

Google Merchant Center (GMC) is the product data platform that powers Google Shopping ads, free product listings, and the Google Shopping tab — requiring merchants to submit a structured product feed that Google uses to match queries, render product cards, and serve Performance Max and Shopping campaigns.

How we integrate Google Merchant Center with Shopify

Ecom Majesty connects Shopify to Google Merchant Center via the Google & YouTube channel app (the official Shopify–Google integration), which handles the initial catalogue sync and basic feed submission. The real work is feed quality: Ecom Majesty audits the automatically generated feed against GMC's product data specification, identifying and fixing common Shopify-to-GMC mapping gaps — missing GTINs, incorrect Google product categories, non-compliant title structures, and image policy violations. Where the native channel app's feed flexibility is insufficient, Ecom Majesty implements a supplemental feed (via Google Sheets or a dedicated feed management app) to layer in custom labels, enhanced titles, and sale price annotations. Ecom Majesty also resolves GMC account-level issues (website claim, shipping settings, tax configuration) and verifies that the feed passes GMC's diagnostic checks before paid campaigns go live.

What the work involves

• Catalogue connected through the Google & YouTube channel app, then the auto-generated feed audited against GMC's product data spec.
• Common Shopify-to-GMC gaps fixed — missing GTINs, wrong Google product categories, non-compliant titles, image policy violations.
• Supplemental feed implemented for custom labels, enhanced titles and sale-price annotations where native flexibility falls short.
• Account-level issues resolved (website claim, shipping, tax) and the feed verified against GMC diagnostics before campaigns go live.
