Free traffic Google still gives away
Since 2020, Google has shown unpaid product listings across the Shopping tab and in various placements on Search, Images and Lens. If your products are not in Google Merchant Center, you are invisible on those surfaces while competitors appear with images, prices and stock status. Free listings will not replace paid Shopping for volume, but they are genuinely free demand, and the setup takes an afternoon.
The Shopping tab is the core surface: shoppers filtering by price, brand and delivery see free listings ranked by relevance and data quality. Rich results on the main search page can draw from the same product data. Everything depends on one asset: a clean, complete product feed.
Setting up Google Merchant Center
Merchant Center Next, the current version of the platform, simplified what used to be a fiddly setup. The steps for a UK store:
- Create a Merchant Center account at merchants.google.com using the Google account that owns your other Google properties.
- Verify and claim your website: via the Google tag if you already run Analytics or Ads, through Search Console if the site is verified there, or with a DNS record.
- Complete your business details: trading name, address and customer-service contact. Google checks these against your website footer and policy pages.
- Configure shipping: UK delivery cost, speed and any free-delivery threshold. Mismatches between the feed and your checkout are a top disapproval cause.
- Add your returns policy with a link. UK consumer-law expectations apply, and Google increasingly surfaces returns information directly on listings.

Getting the product feed right
On Shopify, the Google & YouTube app syncs your catalogue automatically and keeps price and stock current. WooCommerce stores should use the official Google for WooCommerce plugin. Smaller catalogues can run happily from a Google Sheets feed; larger or custom-built stores usually use the Content API or a feed tool such as DataFeedWatch.
Whatever the route, the attributes doing the heavy lifting are id, title, description, link, image_link, price, availability, brand, and GTIN wherever products carry barcodes. Titles matter most for matching, so front-load the terms buyers search: "Men's Leather Chelsea Boots Brown Size 9" beats "The Harrington Boot". Keep descriptions factual and specific, because Google matches on those too.
Fixing the most common disapprovals
Most new accounts hit disapprovals in the first fortnight, and almost all fall into a handful of patterns:
- Price or availability mismatch: the feed says £24.99, the page says £22.99. Add valid Product structured data (schema.org markup) so Google's crawler reads the same values shoppers see, and enable automatic item updates in Merchant Center as a safety net.
- Missing or incorrect GTINs: use the real barcode, or for genuinely barcode-free products such as handmade goods set identifier_exists to false rather than inventing numbers.
- Image problems: watermarks, promotional text or logos overlaid on product images get disapproved; use clean photography on plain backgrounds.
- Misrepresentation: this account-level suspension usually traces to missing contact details, no returns policy or a checkout Google's crawler cannot complete. Make a phone number or email, a physical address and clear policies easy to find.
- Missing shipping information: set UK shipping in Merchant Center even when delivery is free; "free" is a value that must be stated, not an omission.
How free listings work alongside paid Shopping
The same feed powers both. Free listings continue whether or not you run ads, so a well-maintained feed keeps working through any pause in paid spend. When you do advertise, Performance Max and Standard Shopping campaigns draw on identical product data, which means every feed improvement (better titles, correct categorisation, complete attributes) raises the quality of free and paid placements at the same time.
Two UK-specific notes. Comparison Shopping Services (CSS) partners are relevant only to paid Shopping ads, not free listings, so you can ignore CSS sales pitches while running free listings alone. And Merchant Center's promotions feature lets UK sellers attach voucher codes to listings, which can lift click-through on both surfaces at no extra cost.
Key Takeaway
Create a Merchant Center account, verify your site, and feed it clean product data via the Shopify Google & YouTube app or Google for WooCommerce. Get titles, prices, GTINs and shipping right, add Product structured data to prevent mismatch disapprovals, and check diagnostics weekly. Free listings cost nothing, keep working when ads pause, and every feed improvement you make also strengthens any future Performance Max campaign.
Quick wins for your first month
- Rewrite your top 20 product titles to front-load search terms: product type, key attribute, brand, size and colour.
- Add Product structured data sitewide so automatic item updates can prevent price-mismatch disapprovals before they happen.
- Connect your review platform or a ratings feed once you meet the volume threshold; star ratings improve click-through on listings.
- Check the product diagnostics view weekly for new disapprovals rather than waiting for a warning email.
- Compare Shopping-tab impressions and clicks in Merchant Center's performance reports month on month as feed quality improves.
None of this requires ad spend, which makes free listings one of the few compounding, zero-media-cost channels left in UK ecommerce. Once the feed is clean, the step up to a small Performance Max test is far smoother too. If you would rather hand the feed work to someone who does it every week, our team can help.
