Google Shopping is a separate results block with product photo, name, price, and store name that appears at the top of Google for commercial queries. For online stores, it's one of the most effective advertising channels: the buyer sees the product and price before clicking, so clicks are more targeted and conversion is 30–40% higher than search ads.

What is Google Merchant Center

Google Merchant Center (GMC) is the platform through which you send your product information to Google. Without GMC, Google Shopping is unavailable. GMC receives a product feed (a list of products with attributes) and uses it to display your products in Shopping, free listings, and Performance Max campaigns.

Step 1: Registration and site verification

Go to merchants.google.com and create an account. Enter your store name, country, and time zone. Then verify ownership of your site — add a meta tag or upload an HTML file to the server. After verification — claim the site. Connect GMC to your Google Ads account via Settings → Linked Accounts.

Step 2: The product feed — the heart of Merchant Center

A feed is a structured file (XML or CSV) with information about each product. Required attributes: id (unique product identifier/SKU), title (product name — the most important relevance attribute), description (up to 5,000 characters), link (product page URL), image_link (main image URL), price (format: "100.00 UAH"), availability (in_stock / out_of_stock), condition (new / used), brand, gtin or mpn (required for branded products).

Step 3: Product title optimization

The title is the most important relevance factor in Shopping. Correct title structure:

  • For clothing: Brand + Gender + Product Type + Color + Size

  • For electronics: Brand + Model + Type + Key Specs

  • For food: Name + Weight/Volume + Brand

Bad title example: "Men's jacket." Good title example: "Nike Air Max Men's Winter Jacket Black Size L."

Step 4: Image requirements

White or light background for clothing and accessories, product occupying 75–90% of the image area, no watermarks or text on the photo, minimum size 100x100 px (recommended 800x800+), JPEG or PNG format.

Step 5: Shipping setup

Google requires accurate shipping cost and timing information. Configure in GMC: Shipping → Shipping Services → add rules. Incorrect shipping terms are a frequent reason for product disapproval.

Free listings in Google Shopping

Since 2020, Google allows products to appear in Shopping for free — in the "Shopping" tab and partially in main results. To activate: in GMC go to Growth → Manage Programs → activate "Free Listings." Free traffic is smaller than paid, but with a good feed can bring 10–30% additional clicks at no cost.

Performance Max: the next level

Performance Max (PMax) is a next-generation campaign combining Shopping, Search, Display, YouTube, Gmail, and Discover in one campaign with automatic optimization. Requirements: GMC connected, feed uploaded, conversions configured, ideally 30+ conversions per month for the algorithm to work stably.

Common product disapproval reasons

  • Price mismatch between site and feed — Google checks automatically; discrepancies cause disapproval

  • Inaccessible image — URL returns 404 or image doesn't meet requirements

  • Missing GTIN for branded products — required for most branded categories

  • Incorrect price format — must be "100.00 UAH", not "100 hrn"

  • Link leads to 404 — product URL in feed doesn't match actual URL

  • Insufficient shipping information — terms not set up or inaccurate

Check product status in GMC weekly. Google sends detailed disapproval reports with specific reasons and fix recommendations.
