If you sell products online, Google Merchant Center is where your shop and Google meet. It holds your product data: names, prices, photos, stock levels, shipping and returns. From that one source Google can show your products in free listings and, if you choose to pay, in Shopping ads. Many small shops never set it up, or set it up once and then lose products to warnings they do not understand.
This guide explains what Merchant Center does, what changed in Europe in 2026, what your shop needs before you start, and which product data decides whether your products appear at all.
Free listings and Shopping ads: two ways to show products
Google offers two routes, and both use the same product data from Merchant Center:
- Free listings. Your products can appear at no cost on Google surfaces such as the Shopping tab, Google Images, Lens, YouTube and Maps. According to Google, new Merchant Center accounts are opted in to free listings by default.
- Shopping ads. Paid ads with a product photo and price, run through a linked Google Ads account. You pay per click and decide the budget.
Free listings are a good place to start. They cost nothing, and they show you quickly whether your product data is in good shape before you spend money on ads.
What changed in Europe in 2026
Since mid-September 2026, retailers and industry trackers have reported that free product listings and the "Popular products" carousels have largely disappeared from the main Google Search results in the European Economic Area. Google's Ads Liaison linked the change to the requirements of the EU Digital Markets Act. Products can still appear for free on other Google surfaces, for example the Shopping tab and Google Images.
Google also states that in a list of European countries, including Germany, France, Greece and the United Kingdom, Shopping ads and free listings are placed through a Comparison Shopping Service (CSS). Google Shopping is one of these services, and you can choose another one.
The practical consequence: do not count on free visibility in the main search results if you sell in the EEA. A clean product feed still matters, because the same data feeds the Shopping tab, image results and any Shopping ads you run later.
Before you open the account: check your shop
Most suspensions and warnings start on the website, not in Merchant Center. Google's help pages ask for the following, and it pays to fix it first:
- Contact details. At least a business address, phone number, email address, contact form or business social media profile that shoppers can find before checkout. The details should match what you enter in Merchant Center.
- Return and refund policy. Clear information on your website, visible without logging in, covering returns because a customer changed their mind, not only faulty goods. If you do not accept returns, say so plainly.
- Shipping information. Costs and delivery times that match what you will enter in Merchant Center.
- A working checkout on HTTPS. Test it with a real order before you submit anything.
- No loose ends. Remove placeholder text, fix broken links, and make sure prices and stock on each product page are correct.
Setting up Merchant Center in five steps
- Create the account and add your business information: business name, address and phone number, as they appear on your website.
- Verify and claim your website. Google offers several methods: through your shop platform, an HTML tag or file, Google Tag Manager or Google Analytics. Where Google already has the information it needs, verification can happen automatically.
- Set up shipping and returns under "Shipping and returns". Shipping settings are required in many countries. Return policies in Merchant Center are optional, but they must match your website if you add them.
- Add your products. Choose one of the three ways described below.
- Check the diagnostics. Open the product and account issues in Merchant Center a few days after the upload and fix what Google reports.
Three ways to get your products into Merchant Center
- Let Google find them on your website. If your product pages carry structured data (title, price, availability), Google can add the products automatically. Your site must be verified and must not block Googlebot. Google checks for new products and changes at least once every 24 hours.
- Use your shop platform's integration, for example the Google & YouTube app on Shopify. This is usually the easiest route for a small shop, because prices and stock stay in sync.
- Upload a product file, for example from Google Sheets. This gives you full control, but you have to keep it up to date yourself.
If the same product reaches Merchant Center twice, Google keeps the version you uploaded rather than the one it found on your site.
The product data that decides everything
Whether a product appears, and for which searches, depends on the data you send. These attributes matter most:
| Attribute | What Google expects |
|---|---|
| ID | A unique value per product, up to 50 characters. Use your SKU and keep it unchanged. |
| Title | Up to 150 characters, matching the product page. No promotional text such as "free shipping". |
| Description | Up to 5,000 characters about the product only, without links to your store or sale messages. |
| Link | The product page on your verified domain. |
| Image link | A photo that accurately shows the product, without watermarks, borders or placeholders. From 31 January 2027 Google requires at least 500 x 500 pixels for all product images. |
| Availability | in_stock, out_of_stock, preorder or backorder, matching the product page. |
| Price | Amount and currency, for example 49.00 EUR. Outside the US and Canada the price includes VAT. |
| Brand | Required for new products. Leave it empty if there is no brand, never "N/A" or "Generic". |
| GTIN | The barcode number, if the product has one. Only submit a GTIN you are sure is correct. |
| Condition | Required if the product is used or refurbished. |
Good titles do more work than any setting. Start with what the product is, then add the details buyers search for: brand, material, size, colour or model. "Linen cushion cover 50 x 50 cm, sand" will be found for far more searches than "Summer Dream".
Why products get disapproved, and how to fix it
- Price or stock do not match the website. Merchant Center can correct price, sale price, availability and condition automatically. Google says these automatic item updates are switched on by default and work best with structured data on your product pages.
- Misrepresentation or "website needs improvement". Usually missing or unclear business details, policies or checkout. Work through the shop checklist above.
- Missing return policy or contact information. Add it to the website, then make sure Merchant Center shows the same.
- Image problems. Replace placeholder images and photos with watermarks or borders.
If your account receives a warning or is suspended, fix the cause first and then request a review in Merchant Center. Google says reviews typically take three to seven business days. Repeated unsuccessful requests can lead to a cool down period during which you cannot ask again, so it is worth getting it right the first time.
Quick checklist
- Contact details, returns and shipping clearly shown on the shop
- Checkout tested with a real order on HTTPS
- Merchant Center account with the same business details as the website
- Website verified and claimed
- Shipping and returns set up in Merchant Center
- Products added through structured data, your shop platform or a product file
- Titles, photos, prices and stock checked against the product pages
- Diagnostics reviewed a few days after the first upload, then once a month
Merchant Center is one part of selling online. Product pages, shipping information, abandoned cart emails and tracking matter just as much, and our online shop marketing service covers them together. If your shop also sells to local customers, our guide on asking for Google reviews without breaking the rules is a good next read.
