Why does feed copy need its own approach?
On your product page, a shopper has already clicked. In Google Shopping and free product listings, your title and image compete side by side with other stores, often truncated to a few words, and Google uses your feed text to decide which searches your product matches. Feed copy therefore puts facts before style. This guide focuses on titles, descriptions and attributes; our guide to Google Shopping feeds with variants covers per-variant images and item groups.
How do products get from Shopify to Merchant Center?
- Install Shopify’s Google & YouTube sales channel and connect a Google Merchant Center account.
- Products sync with their title, description, images, price, availability, barcode and variant options.
- Google reviews each item and lists issues in Merchant Center’s products and diagnostics views.
- Approved items can appear in free listings and, if you run them, Shopping ads.
Feed apps can transform data on the way, for example building a feed title from several attributes without changing your on-page title.
How should I write Google Shopping titles?
Google allows up to 150 characters for the title attribute, but shoppers often see only the first part. Put the most important attributes first. A widely used pattern by category:
| Category | Pattern | Example (fictional brands) |
|---|---|---|
| Apparel | Brand + Gender + Product type + Material + Color + Size | Northwind Men’s Merino Crew Sweater, Navy, M |
| Beauty | Brand + Product type + Key ingredient + Size | Lumen Vitamin C Face Serum, Fragrance-Free, 30 ml |
| Electronics | Brand + Product type + Key spec + Compatibility | Voltio 65W USB-C Charger, 2 Ports, for Laptops and Phones |
| Home | Brand + Product type + Material + Dimensions | Fjord Round Side Table, Solid Oak, 45 cm |
| Food | Brand + Product + Variety + Weight | Highland Coffee Beans, Single Origin Medium Roast, 250 g |
Each variant becomes its own item, so variant titles can include color and size even though your on-page product title should not. Our product title formula covers the on-page version.
What is not allowed in feed titles?
- Promotional text such as “free shipping”, “sale” or “best price”.
- Excessive capitalization or symbols.
- Information about other products or competitors.
- Keyword lists that do not describe the item.
Check Google’s product data specification for the current editorial rules; they are enforced through disapprovals.
How should I write feed descriptions?
Google allows up to 5,000 characters. Unlike your page, there is no layout, so clarity matters most.
- Start with what the product is and its most important attribute, in one sentence.
- Add the details that match searches: material, dimensions, compatibility, use case.
- Describe only this product: no store policies, links, or comparisons with other items.
- Keep it accurate and consistent with the landing page.
A well-structured Shopify description usually works as a feed description once headings and links are stripped. Our description templates produce copy that fits both.
Which attributes matter beyond title and description?
| Attribute | Why it matters | Shopify field |
|---|---|---|
| GTIN | Required for products with a manufacturer-assigned barcode; helps matching | Variant barcode |
| Brand | Required for most products | Vendor |
| MPN | Identifier when no GTIN exists | Often via metafield or feed app |
| Google product category | Helps classification | Product category / feed mapping |
| Color, size, gender, age group | Required for apparel in many countries | Variant options and metafields |
| Image link | Must show the correct variant | Variant image |
| Price and availability | Must match the landing page | Variant price and inventory |
Why are Shopify products disapproved, and how do I fix them?
- Price or availability mismatch: the page shows a different price or stock than the feed. Check currency, sale prices and app-driven price changes.
- Missing GTIN: add barcodes; mark custom products without GTINs appropriately.
- Image issues: watermarks, promotional overlays, placeholders or images that do not match the variant.
- Missing apparel attributes: add color, size, gender and age group.
- Policy issues: restricted products or claims. Merchant Center names the policy concerned.
Fix the source in Shopify rather than patching the feed when possible, so the page and the feed stay consistent.
Does feed quality affect AI shopping results?
Google’s Shopping Graph draws on Merchant Center data, and Google’s AI shopping experiences build on it, so accurate, attribute-rich feed data is part of being eligible. Other assistants read your pages directly, which is why the page and feed should agree. See how AI shopping assistants pick products.
How do I audit feed-ready content quickly?
Start with Merchant Center’s diagnostics for disapprovals, then check a few product pages in the free product page grader for title, variant image and structured data issues that feed into the same problems.
How do I improve feed titles without touching my product pages?
- Decide on a title pattern per category, using the table above.
- Use a feed app or Merchant Center feed rules to build feed titles from attributes such as vendor, product type, color and size.
- Preview a sample of items in Merchant Center before applying the rule to everything.
- Compare impressions and clicks for the changed items over several weeks.
This keeps your on-page titles short and readable while giving Google the attribute-rich titles that match specific searches.

Frequently asked questions
What is the title limit in Google Merchant Center?
Google allows up to 150 characters for the product title attribute. Shoppers usually see only the first part, so put the most important words first.
Can my feed title differ from my Shopify product title?
Yes. Feed apps and Merchant Center rules let you build feed titles from attributes, as long as they describe the same product accurately and do not add promotional text.
Why are my Shopify products disapproved in Merchant Center?
Common reasons include missing GTINs, price or availability mismatches between feed and page, promotional text in titles, images with watermarks and policy issues. Merchant Center lists the exact reason for each item.
Do I need GTINs for Shopify products?
Google requires GTINs for products that have one assigned by the manufacturer. Enter them in the barcode field in Shopify. Custom or handmade products without a GTIN can be marked as such.
