Shopify products missing or out of date in Google Merchant Center? How to check
Shopify's Google & YouTube app says your products are syncing, and Merchant Center shows no errors. But Merchant Center has fewer products than Shopify, or still shows an old price or stock level. Here's how to find exactly which ones, and why.

Missing, stale or disapproved: three different problems
- Disapproved products are in Merchant Center with an issue. Google's own diagnostics show these.
- Missing products never reached Merchant Center at all, so there's no error to see.
- Stale products are there, but with an old price, stock level or title. Merchants report Shopify updates taking 24–72 hours to reach Merchant Center, or old data coming back.
This guide is about the last two, which Google's diagnostics don't flag.
Step 1: compare the counts, then trace a few products
- Compare the number of products the Google & YouTube app says it's syncing with the number in Merchant Center (Products, All products). Remember that Merchant Center counts each variant, and each country it's listed for, separately.
- Pick 5–10 products that are in Shopify but you can't find in Merchant Center, and trace each one. That's quicker and safer than changing the whole catalogue.
- For stale data, pick products whose price or stock changed recently and compare Shopify with Merchant Center.
Step 2: rule out the usual causes
- Markets and shipping: a product only syncs for a country where it's available and you ship. Check the missing products' markets match the countries in Merchant Center.
- The sales channel: check each missing product is published to the Google & YouTube channel and is active.
- Product IDs: Merchant Center IDs from the app include the country and the Shopify product and variant. One merchant found an invalid country code in them, which caused duplicates and gaps.
Step 3: be careful with reinstalling
Reinstalling the app is the most common advice, but merchants warn it can change your product IDs, losing their history in Merchant Center. Try disconnecting and reconnecting Merchant Center inside the app first.
Would an automatic check help?
We build small apps that check that one business tool really has what another says it sent, and stay quiet unless it doesn't. We're deciding whether to build one for this: comparing what Shopify says should be on Google with what Merchant Center actually has, product by product, and emailing you about missing or stale ones. If this has happened to you, tell us how often and what it cost. It helps us decide.
