Google Shopping Feed Optimization
Your product feed in Google Merchant Center drives every Shopping and Performance Max campaign. It holds your titles, descriptions, images, prices, and attributes. Google uses it to decide which searches your products appear for and how they look. Many advertisers run the default export from their store, so feed work is often the cheapest improvement available.
How it works
Shopping ads have no keywords. Google reads your feed to decide which queries each product matches, so titles, descriptions, and attributes act as your keywords. “Blue Shirt” matches far fewer searches than “Men’s Slim Fit Oxford Button-Down Shirt, Navy, 100% Cotton”. Feed optimization means filling in every attribute so products match more relevant queries, look better in results, and land on the right page.
How to do it
- Rewrite titles as Brand + Product Type + Key Attributes (color, size, material, gender). Put the most important words first, because long titles get cut off.
- Expand descriptions with specifications, use cases, and the words shoppers search for.
- Fill in every relevant optional attribute: color, size, material, pattern, age_group, gender, GTIN or MPN, and product_type.
- Use custom labels (custom_label_0 to custom_label_4) to tag products by margin, bestseller status, season, or price band. Use them to split campaigns or asset groups.
- Add a supplemental feed in Merchant Center to override titles and other attributes without changing your store’s export.
What to measure
- Approved products: approved items divided by submitted items in Merchant Center. Fix disapprovals as they appear.
- Impressions per product: total Shopping impressions divided by active products.
- CTR by product: find products with many impressions and few clicks. The cause is usually the title, image, or price.
Best practices
- Start with your top products by revenue and edit their titles and images by hand.
- Test title formats in a supplemental feed or a feed management tool before changing every product.
- Use clear, high-resolution images on plain backgrounds.
Common pitfalls
- Using manufacturer titles as-is (“SKU12345 - Widget”).
- Missing required attributes such as GTIN, condition, or availability, which gets products disapproved.
- Leaving product_type and google_product_category empty or wrong, which makes matching worse.
