6 Reasons Why Your Google Merchant Centre Product Feed Is Not Working

Google Shopping campaigns can be absolute goldmines when they work properly, but when your Google Merchant Centre product feed starts throwing errors or disapproving products, it feels like watching potential revenue slip through your fingers. After managing hundreds of shopping feeds over the years, I can tell you that most feed issues stem from the same recurring problems, and the frustrating part is that many of these are completely avoidable with the right setup and maintenance.

The reality is that Google's product feed requirements have become increasingly strict, and what worked last year might not cut it today. Whether you're launching your first shopping campaign or trying to fix an existing one that's underperforming, understanding these common pitfalls can save you weeks of troubleshooting and thousands in lost revenue.

Here are the six most common reasons why your Google Merchant Centre product feed isn't delivering the results you expect, along with practical solutions you can implement straight away.

Incorrect or Inconsistent Pricing

Price discrepancies are one of the fastest ways to get your products disapproved, and Google's getting increasingly aggressive about checking these. If the price in your feed doesn't match what customers see when they click through to your product page, Google will suspend your products faster than you can say "conversion rate".

Take for example an electronics retailer who couldn't understand why their top-selling products kept getting disapproved. After digging into their feed, they discovered their inventory management system was updating prices on their website hourly, but their product feed was only refreshing once daily. During busy periods, this meant customers were seeing prices that were sometimes £50-100 higher than what Google was advertising.

The problem gets worse when you factor in promotional pricing. Many retailers run flash sales or member-only discounts but forget to exclude these from their base product feed. Google crawls your landing pages and if they find a different price, your products get flagged immediately.

Quick fix: Set up automated feed updates that sync with your inventory system at least every few hours. Use Google's automatic item updates feature to let Google fetch current prices directly from your structured data, and always test your landing pages after price changes.

Unavailable or Broken Landing Pages

Nothing kills a Google shopping campaign faster than sending customers to pages that don't exist or don't work properly. Google regularly crawls your product URLs, and if they encounter 404 errors, server timeouts, or pages that don't contain the advertised product, your items get disapproved.

This issue often crops up during website migrations or when retailers discontinue products but don't update their feeds accordingly. There have been many cases where entire product catalogues were disapproved because a website update changed URL structures without proper redirects being put in place.

Mobile compatibility is another critical factor here. Google predominantly uses mobile-first indexing, so if your product pages aren't mobile-friendly or load slowly on mobile devices, this can impact your feed approval status. A fashion retailer I worked with saw their approval rates drop by 40% because their product pages were taking over 8 seconds to load on mobile.

Quick fix: Regularly audit your product URLs using tools like Screaming Frog or Google Search Console. Set up monitoring alerts for 404 errors on product pages and ensure all product URLs redirect properly if you change your site structure. Test your pages on mobile devices and aim for loading times under 3 seconds.

Missing or Poor Quality Product Images

Visual appeal drives Google Shopping success, but many retailers either skip images entirely or use photos that don't meet Google's requirements. Products without images simply won't get approved, and low-quality images will struggle to compete in the auction.

Google requires images to be at least 100x100 pixels, but in reality, anything smaller than 800x800 pixels will perform poorly. The sweet spot for shopping ads is typically 1200x1200 pixels or larger. Images also need to show the actual product clearly, with minimal text overlay and no promotional badges or watermarks.

Google also requires that your main product image matches exactly what you're selling. If you're selling a blue jumper, the main image needs to show that blue jumper, not a model wearing it in a lifestyle shot where the product is barely visible.

Quick fix: Audit your product images and ensure they're at least 800x800 pixels with white or neutral backgrounds. Remove any text overlays, promotional banners, or watermarks. Make sure your main image clearly shows the product you're selling and matches your product title exactly.

Missing Essential Product Identifiers

Google requires specific product identifiers like GTIN (Global Trade Item Number), MPN (Manufacturer Part Number), or brand information for most product categories. Missing these identifiers is one of the quickest ways to get your products disapproved, especially for branded items.

The challenge is that many retailers don't have this information readily available in their product databases, or they have it but don't know how to format it correctly for Google. GTINs need to be exactly as they appear on the product packaging, with no extra characters or formatting.

For unique or custom products, you might be able to use Google's identifier_exists attribute set to FALSE, but this only works for genuinely unique items like handmade crafts or custom-manufactured goods. Trying to use this for branded products will result in disapprovals.

Quick fix: Contact your suppliers to obtain GTINs and MPNs for all branded products. Use tools like the GS1 database to verify GTIN accuracy. For products without identifiers, ensure you're only using identifier_exists = FALSE for genuinely unique items, not as a shortcut for missing data.

Out of Stock Products Clogging Your Feed

Advertising products you can't actually sell is a waste of ad spend and can harm your Merchant Centre account health. Google tracks how often customers click on your products only to find them unavailable, and too many out-of-stock clicks can impact your overall account quality score.

The availability attribute in your feed should accurately reflect your stock levels, but many retailers either forget to update it or don't have systems in place to sync inventory with their shopping feed. This becomes particularly problematic during busy periods like Black Friday when stock levels change rapidly.

Some retailers try to keep out-of-stock products active with extended handling times, but this often backfires. If customers have to wait 3-4 weeks for delivery when competitors offer next-day shipping, your conversion rates will suffer.

Quick fix: Implement automated inventory sync between your stock management system and your product feed. Set up alerts when key products go out of stock and pause advertising immediately. Use Google's automatic item updates to sync availability in real-time.

Poor Product Title and Description Optimisation

Your product titles and descriptions need to work for both Google's algorithm and actual customers, but many retailers get this balance completely wrong. Titles stuffed with keywords might seem like good SEO practice, but Google Shopping rewards clarity and relevance over keyword density.

Effective shopping feed titles should include the brand, product type, key attributes like colour and size, and material where relevant. They should read naturally while containing the terms customers actually search for. A title like "Nike Men's Running Shoes Air Max 90 Black Size 10 Leather" works much better than "Running Shoes Nike Black Leather Men Trainers Athletic Footwear".

Descriptions should provide additional context and details that don't fit in the title, but avoid marketing fluff. Technical specifications, dimensions, and care instructions are valuable. Marketing phrases like "amazing quality" or "must-have item" add no value and can actually hurt performance.

Quick fix: Rewrite product titles to include brand, product type, and key attributes in natural language. Create unique descriptions that focus on specifications and benefits rather than marketing speak. Use the language your customers actually use when searching, not industry jargon.

Moving Forward with Your Google Merchant Centre Success

Getting your Google Merchant Centre product feed working properly isn't just about fixing technical errors, it's about creating a foundation for sustainable shopping campaign growth. The retailers who succeed with Google Shopping are those who treat their product feed as a crucial marketing asset that needs regular attention and optimisation.

Start by auditing your current feed against these six common issues, but don't try to fix everything at once. Prioritise the problems that are causing the most disapprovals or affecting your highest-value products first. Most importantly, set up monitoring and maintenance processes so these issues don't keep recurring.

Remember that Google's requirements evolve constantly, and what works today might need adjustment tomorrow. The key is building robust systems and processes that can adapt to these changes whilst keeping your products visible and competitive in the shopping results.
