A made-up store. Product photos: generated images.
We ran it on 38 real stores. 5 had a stock mismatch.
On 15 October 2026 we checked the 38 Shopify stores linked from Shopify's own examples page, 20 product pages each. At 5 stores, a product page told search engines a different stock status from the one in the store's own product data. We re-fetched each flagged page to confirm it.
How we counted
Source: shopify.com/examples, read 15 Oct 2026. It linked 42 stores, and 38 of them run on Shopify. We read 760 product pages, one request at a time. One store was flagged for a price mismatch, but its product data didn't load when we re-checked, so it isn't counted. Shopify chose these brands to feature, so they're likely better run than most stores. We don't name the stores.
Catalog Truth reads each product page and checks it against your catalog.
Google also reads the product page itself, including the price and stock your theme writes into it for search engines. Switch the comparison to see it.
A real store, scanned live
One of the 38 stores from our field check, scanned by the live checker on 16 October 2026. It read 20 product pages and found 3 sold-out options that the page still marks in stock. We hid the store's name and products. Captions on.

How it works
The checker on this page is Catalog Truth's own checking code, built on 15 October 2026. For each product it reads the public product page, including the product data your theme writes into it for search engines, and the product data your store publishes. Then it compares price and stock for each variant.
The two bugs here are real theme problems. "Static variant pricing that doesn't update when customers select different options" is a known cause of Google price mismatches (ShoppingFeeder help).
