Data quality problems in your product feed are one of the most common reasons Google suspends Merchant Center accounts. Google expects your feed data to be accurate, complete, and consistent with what appears on your website. When it is not, you receive warnings first, then account suspension.
The most frequently flagged data problems are: mismatched prices between feed and landing page, missing or inaccurate GTINs, unavailable products still in the feed, and titles or descriptions that do not match the actual product. Each of these can trigger warnings or suspension depending on severity and frequency.
Google crawls your product pages and compares the price to your feed. If they differ by more than a small margin, you receive a price mismatch error. The most common causes are: feed not updating fast enough after a price change, promotional prices on the website not reflected in the feed, and tax or shipping costs included in one but not the other. Fix price mismatches by ensuring your feed updates at least daily and that your prices include the same tax treatment in both places.
GTINs (Global Trade Item Numbers) are required for products that have manufacturer-assigned barcodes. Submitting incorrect GTINs, GTINs that do not exist in Google's product database, or using invented numbers triggers item disapprovals. Check your GTINs against the manufacturer's documentation. For products without GTINs, set identifier_exists to FALSE and provide brand plus MPN instead.
Products marked as in stock in your feed but showing as out of stock on the landing page are a serious data quality issue. This directly misleads customers and is something Google penalizes quickly. Keep your feed availability in sync with your real inventory. If you use a platform like Shopify or WooCommerce, use their native GMC feed integration to pull live inventory data.
Titles should follow the format: Brand + Product Type + Key Attribute. Avoid promotional language like "best" or "cheapest" in titles. Descriptions should match the product page content without keyword stuffing. Google expects the information in the feed to match what a customer sees when they click through.
GMC Suspension Audit checks your feed and account against 52 policy requirements including all common data quality issues.
