Google Merchant Center product feed troubleshooting and diagnostics for Wix

Getting your Wix Stores products into Google Merchant Center is one thing. Keeping them approved, compliant and performing well is another challenge entirely. This lesson covers the most common product feed errors Wix store owners encounter, how to diagnose them in Google Merchant Center's Diagnostics tab, and the specific fixes for each issue. If your products are being disapproved, have missing attributes, or are not appearing in Google Shopping free listings, this lesson will help you fix it.

How the Wix to Google Merchant Center Feed Works

When you connect your Wix Store to Google Merchant Center, Wix generates a product data feed that Google fetches on a schedule you define. This feed contains all your product information: titles, descriptions, prices, images, availability, GTINs and more. Google then validates every product against its product data specification. Products that fail validation are disapproved and will not appear in Google Shopping results, free listings, or Performance Max campaigns.

Accessing the Diagnostics Tab

Finding and understanding product errors

• Log into Google Merchant Center at merchants.google.com
• Navigate to Products then Diagnostics in the left menu
• The overview shows how many products are active, disapproved, pending, or expiring
• Click on each issue category to see specific error messages and affected products
• Use the "Download all issues" option to get a spreadsheet of every error
• Check the "All items" tab to see the status of individual products

Most Common Wix Product Feed Errors and Fixes

Missing or Invalid GTIN (Global Trade Item Number)

Google requires GTINs (UPCa, EAN, or ISBN) for branded products. If your Wix products are branded items, add the GTIN in the Product Management section of each product. For handmade, custom, or unbranded products, set the identifier_exists attribute to "no" in your product settings. Wix handles this through the "Brand" and "Product identifiers" fields in the product editor.

Price and Availability Mismatch

Google crawls your Wix product pages and compares the price shown to the price in your feed. If they do not match, the product is disapproved. This commonly happens when Wix sale prices end but the feed has not been refreshed yet. Enable automatic item updates in your Merchant Center settings to reduce mismatches, and set your feed to fetch at least daily.

Products Flagged as "Used" When They Are "New"

Google's automated classification may incorrectly flag products as "used" based on keywords in your descriptions like "vintage", "retro", "classic" or "refurbished". Fix this in Google Merchant Center under Products then Automations, where you can create a rule to force the condition attribute to "new" for all affected products. Wix does not give you direct control over this attribute in the feed.

Missing Shipping and Return Policy

Google requires shipping costs and return policies to be configured. If your products show "missing shipping information", link your Google Merchant Center account to your Google Search Console property. Then configure shipping in Merchant Center under Shipping and returns. Add your return policy with clear time frames and conditions. Also ensure your Wix site has a visible shipping policy and returns policy page.

Image Quality Issues

• Main product image must be at least 100x100 pixels (250x250 for apparel)
• No watermarks, promotional text, or logos overlaid on product images
• Product must fill at least 75% of the image frame
• White or light background preferred for the main image
• No placeholder images or stock photos that do not show the actual product
• Ensure Wix image compression is not degrading quality below Google's thresholds

Optimising Product Titles for Google Shopping

Your Wix product titles feed directly into Google Shopping. Optimise them by including the brand name, product type, key attributes (colour, size, material) and model number where applicable. Google Shopping titles can be up to 150 characters, so use the full space. Format: [Brand] + [Product Type] + [Key Attribute 1] + [Key Attribute 2]. For example: "Nike Air Max 90 Running Shoes - Black/White - Men's Size 10".

Free Listings Optimisation

Google Shopping free listings appear alongside paid Shopping ads and in the Shopping tab. To maximise your free listing visibility, ensure every product has a complete set of attributes (title, description, image, price, GTIN, brand, colour, size), that your product descriptions are detailed and keyword-rich, and that your Wix store has strong organic SEO signals. Products from sites with higher domain authority tend to perform better in free listings.

How to Fix a Price Mismatch Error Between Your Wix Store and Google Merchant Center

How to diagnose and resolve price mismatch disapprovals in Google Merchant Center for your Wix Store products

• Log in to Google Merchant Center at merchants.google.com and navigate to Products then Diagnostics in the left menu.
• Look for a "Price is different from landing page" or similar price mismatch error in the issue list. Click on it to expand the details.
• Note the product IDs listed as affected. Copy the first affected product ID.
• Open a new browser tab and go to your Wix dashboard. Navigate to Wix Stores then Products. Search for the product by name or ID.
• Compare the price shown in your Wix Stores product settings against the price shown in the Merchant Center error. Identify the discrepancy: the most common cause is a sale that ended in Wix but the feed has not yet updated.
• If the price in Wix is correct and up to date, the issue is a feed refresh delay. In Merchant Center, navigate to Content then Feeds, click on your Wix feed, and click Fetch Now to force an immediate refresh.
• If the Wix product price is genuinely wrong, open the product in Wix Stores, correct the price, save, and publish the change.
• Return to Merchant Center and enable Automatic Item Updates if it is not already active. Navigate to Settings then Automatic Item Updates and turn on the Price update option. This allows Google to crawl your product pages and self-correct minor discrepancies.
• After 24 hours, return to the Diagnostics tab and filter for the same error. If the affected product count has dropped, the fix is working.
• For persistent mismatches across multiple products, check whether your Wix currency settings and your Merchant Center target country settings are using the same currency code and format.
