Product feed and Google Merchant Center for webshops
What are a product feed and Merchant Center?
A product feed is a machine-readable file containing your webshop’s product data (name, price, stock, image, identifiers). Google Merchant Center ingests it so your products can appear in Google Shopping results, for free or as Shopping ads.
Most feed problems come from poor product data, not from the ads. I clean up your data so your products can appear correctly in as many places as possible.

In short
- Feed quality determines how many products can appear and at what cost.
- Platform-independent: an XML/CSV feed or automatic sync from your webshop system.
- Product structured data on your site and the feed show the same price and stock.
- Regular error monitoring: disapproved products, missing identifiers, price and stock mismatches.
What I do
From the first feed to ongoing maintenance
Building the feed
Filling the required and recommended attributes: ID, title, description, link, image, price, availability, brand, GTIN/MPN, condition, category.
Improving data quality
Rewriting titles and descriptions for search intent, choosing good images, category mapping and filling missing identifiers.
Product structured data
Product/Offer markup on product pages that matches the feed. I only mark up ratings when they are real reviews visible on the site.
Handling errors
Finding and fixing the causes of disapproved or warned products in line with Google’s policies.
Ads readiness
If you want to run Shopping ads later, the feed and conversion tracking are ready; ad management is discussed separately.
How it works
Data review
I check what data your webshop can output and what is missing or wrong.
Feed and account
I build the feed, set up Merchant Center and verify the submission.
Fixing issues
Based on Google’s feedback I fix disapproved or incomplete products.
Ongoing oversight
Optionally a monthly check so price and stock changes and new products do not cause errors.
What does it cost?
The price depends on the number of products and the state of your webshop data. Prices are VAT-exempt (small-business exemption).

Frequently asked questions
Do I need an advertising budget?
Not necessarily. Google Shopping’s free listings are available independently of Shopping ads. You can start ads later from the same feed.
Which webshop platforms do you work with?
I am platform-independent: if your webshop can export product data or expose it via an API, a feed can be built from it. I will confirm the concrete approach after the review.
What is a GTIN and is it mandatory?
A GTIN is the international barcode identifier of a product. It is requested for most traded goods, so its absence often blocks visibility. If you have none, we look at which exception applies.
How does this relate to Webshop AI Visibility?
Both rely on product data quality. Webshop AI Visibility optimises product pages for AI assistants and search; the feed targets Google Shopping surfaces. The two complement each other well.
