What Merchant Center documents
Google Merchant Center’s product data specification describes attributes used to submit products, including identifiers, titles, descriptions, links, images, price, availability, and category information. Google’s documentation explains how data should be represented for products and variants.
The specification is a technical reference, not a promise of listing approval, impression volume, or sales. Requirements can vary with product type and destination, so a team should consult the current documentation for the catalog and market it is actually submitting.
Make feed review a catalog responsibility
For E-commerce Marketing, begin with a field map: source system, feed attribute, transformation rule, destination page, and accountable owner. Compare live product pages with submitted data, paying attention to price, availability, variant identifiers, image selection, and destination links.
Use a sample-based QA routine for recurring updates and a focused review for large changes such as a new taxonomy or promotion. Resolve errors at the source where possible, and keep an exception list for items that need human review rather than repeatedly applying a broad rule.
Connect compliance checks to merchandising
Feed correctness does not decide which products deserve promotion. Add stock, margin, seasonality, and page readiness to the decision, and confirm that the store can fulfill the promise a product listing makes.
The agency interpretation is that Merchant Center’s schema should be treated as a maintained operating interface between catalog and campaign work. Google documents the data requirements; marketing and commerce teams must verify their own product truth and avoid implying that clean data guarantees performance.
