Merchant Center in the commerce stack
Understand the relationship between Merchant Center, product data, free listings, Shopping and Performance Max.
Product data foundations
Titles, descriptions, GTINs, brands, images, price, availability and landing-page consistency determine whether Google can understand and approve products.
Feeds and data sources
Compare scheduled feeds, API connections, platform integrations and supplemental data.
Diagnostics and disapprovals
Treat diagnostics as a prioritised quality queue. Fix policy and data mismatches at source rather than repeatedly patching exports.
I’ll help you identify the highest-value next step rather than selling you a generic package.
Titles and descriptions
Write product data for clarity and search relevance without keyword stuffing.
Images and creative quality
Use clean primary images and useful additional imagery; product data quality and creative quality work together.
Shipping, returns and promotions
Keep commercial policies consistent across feed, landing page and account settings.
Free listings
Free product visibility can provide incremental discovery but still depends on eligibility and data quality.
Shopping and Performance Max
Merchant Center supplies product data; campaign structure, bidding and creative remain Google Ads decisions.
Measurement
Connect Ads, GA4 and ecommerce outcomes so optimisation does not stop at clicks.
Common failure modes
Price mismatches, missing identifiers, weak titles, broken landing pages and policy issues are recurring causes of lost visibility.
Monthly workflow
Review diagnostics, product coverage, best/worst product groups, search demand and commercial outcomes.
