Google just rolled out new structured data properties for merchants: Category and Sale Duration. If you run an online shop, or sell products alongside your services, this update directly affects your search visibility.
The good news? You don’t need to be a technical wizard to use them. The better news? North London businesses that implement these today will rank above competitors who wait.
Tip 1: Add Product Category Data to Every Listing
Google’s new Category property lets you tell search engines exactly what your product is, how it fits into the broader market, and why it matters to the person searching.
Instead of Google guessing that your “vintage leather jacket” might be apparel, or a collectible, or furniture, you declare it explicitly. This precision cuts through ambiguity and helps Google match your product to the right search intent.
How to apply it: Log into your Google Merchant Centre and update your product feed. For each item, add the Category field using Google’s standardised categories (Electronics, Apparel, Home & Garden, etc.). If you sell handmade goods or niche items, match them to the closest category. Be specific, not vague.
Example: Don’t list “Gift.” Instead, use “Gift > Jewellery” or “Gift > Home Décor.”
If you’re using a platform like Shopify or WooCommerce, your categories may already sync to your feed. Check your integration settings to confirm the data is flowing to Google.
Tip 2: Use Sale Duration to Capture Urgency-Driven Traffic
The new Sale Duration property tells Google when a promotion or special price ends. This is powerful because it signals scarcity and urgency, two signals that drive clicks.
When someone searches “leather jackets on sale,” Google can now show your product with the exact end date of your offer. That transparency builds trust and increases click-through rates.
How to apply it: Set a start and end date for any promotional pricing in your product feed. Use ISO 8601 format (2026-07-31) so Google reads it correctly. Update this weekly or as often as your promotions change.
If you run seasonal sales, summer clearance, Black Friday, January bargains, add Sale Duration data to those campaigns specifically. North London businesses selling fashion, home goods, or seasonal services see the biggest uplift.
Tip 3: Implement Structured Data Across Your Entire Feed, Not Just Featured Products
Many small business owners add structured data only to their best-selling or highest-margin products. That’s a mistake.
Google’s algorithm rewards consistency. If 80% of your feed has Category and Sale Duration data but 20% doesn’t, Google may not fully trust the data quality across your entire catalogue. Treat structured data like you’d treat customer service: do it for every customer, every time.
How to apply it: Audit your product feed now. Identify gaps where Category or Sale Duration is missing. Add data systematically, starting with your top 100 products by revenue or traffic, then work through the rest.
Use a spreadsheet or CSV export to batch-update missing fields. Most platforms support bulk uploads, which saves hours of manual work.
Tip 4: Monitor Your Merchant Centre for Errors and Warnings
Google’s Merchant Centre dashboard shows you exactly where your structured data is working, and where it’s broken.
After you implement Category and Sale Duration fields, check the “Diagnostics” and “Performance” tabs in your Merchant Centre. Look for warnings like “Missing Sale Duration” or “Invalid Category.” These aren’t just notifications; they’re search visibility leaks.
How to apply it: Spend 15 minutes a week reviewing your Merchant Centre dashboard. Fix errors within 2, 3 days. If Google flags 500 products with missing Category data, you’re losing visibility on those 500 items. Fix them batch-by-batch.
Set a calendar reminder every Friday morning. Check Merchant Centre, note any new warnings, and prioritise fixes for the following week.
Tip 5: Test Your Structured Data with Google’s Rich Results Test
Google provides a free tool, the Rich Results Test, that shows you exactly how your structured data appears in search results before it goes live.
This is your quality control checkpoint. Before you publish product updates to your live feed, paste your URL or structured data code into the test tool. Confirm that Google reads your Category and Sale Duration fields correctly, and that the rich result preview looks right.
How to apply it: After updating your first 10, 20 products with new structured data, test them. If the preview looks wrong, fix the data format before rolling out to your full catalogue. This prevents widespread errors that take weeks to fix.
Use this test monthly, especially after any major feed changes (like platform migrations, new product launches, or promotional updates).

Frequently Asked Questions
Do I need to use Category and Sale Duration data to rank in Google Shopping?
No, they’re not mandatory. But they’re now a ranking signal. Products with clean, complete structured data rank higher than those without it, assuming other factors are equal. If your competitor implements this and you don’t, they’ll rank above you.
How long does it take to see results from adding structured data?
Google’s crawler needs time to discover and process your updated feed. Most businesses see ranking changes within 2, 4 weeks. Full impact usually shows after 6, 8 weeks once Google’s index fully refreshes.
What happens if I fill in the Sale Duration field incorrectly?
Google will flag it as a warning in Merchant Centre. The product may not display with sale pricing or urgency signals. Fix it as soon as you see the warning, and Google will reprocess the data within a few days.
Can I use structured data for services as well as products?
Yes. If you sell services, like web design in Finchley or website maintenance, you can use structured data for those too. Google also supports Service schema, which works similarly to merchant listing schema.
What if my ecommerce platform doesn’t support structured data fields?
Most modern platforms (Shopify, WooCommerce, BigCommerce) support structured data through native fields or plugins. If yours doesn’t, it’s worth migrating to one that does. Structured data is no longer optional, it’s table stakes for ecommerce in 2026.
