Your Google Shopping, Meta Catalog, and Amazon listings are only as good as the data feed powering them. Yet most eCommerce operators spend thousands optimizing bids and creative while completely ignoring the feed quality that determines whether their products even show up.
The 5 Most Common Data Feed Errors
1. Weak Product Titles
Most brands write titles for humans browsing their website. Feed titles need to be written for search algorithms. The winning formula: Brand + Product Type + Key Attribute + Size/Color/Variant.
2. Missing or Thin Descriptions
Descriptions under 500 characters consistently underperform. The description field is prime SEO real estate — use it. Include materials, dimensions, use cases, and secondary keywords.
3. Incorrect or Missing GTINs
Google requires GTINs (barcodes) for branded products. Missing GTINs result in disapprovals and reduced visibility. If you're selling branded goods without GTINs, you're invisible in a large percentage of relevant searches.
4. Stale Pricing and Availability
A feed that updates once per day can't keep up with fast-moving inventory. Showing 'In Stock' for items that sold out hours ago destroys conversion rates and wastes ad budget. High-performing operations update feeds every 15–30 minutes.
5. Category Mismatches
Google Product Taxonomy has thousands of categories. Most brands use a handful. Proper categorization unlocks relevant search traffic that competitors are missing entirely.
The Revenue Impact
One of our clients — a New York-based retailer with 14,000+ SKUs — saw their Google Shopping ROAS jump from 1.8x to 3.9x within 90 days of a comprehensive feed overhaul. The change was entirely in data quality and structure.
