How to Fix Product Landing Page Errors in Merchant Center

Google routinely crawls the landing pages in your product data. If it can’t reach a page, the product is disabled until the page is accessible again. Unlike content issues, this is about whether Google can load the page at all.

The good news is that landing page errors are usually technical and testable. This guide walks through each error type Google lists, how to reproduce it, how to fix it on Shopify, WooCommerce or a custom site, and what to do after the fix.

What “Product page unavailable” means

Google’s Product page unavailable fix article explains that the error appears when the landing page set in link, link_template or mobile_link can’t be accessed. Affected products are disabled until the page is accessible.

Google crawls landing pages routinely, not only when you submit data. A page that worked when you uploaded the feed can still trigger the error later if the site goes down, a product is deleted, or a security setting starts blocking crawlers.

Landing page errors are different from content mismatches. If Google can load the page but the price or availability doesn’t match your data, see the guides on price mismatches and availability mismatches instead.

The error types and what causes them

Error	What it means	Common causes in practice
Page not found (404)	The URL returns a 404	Product deleted or unpublished, URL handle changed, variant URL no longer valid
Too many redirects	The URL goes through more than two redirects	HTTP to HTTPS to www to trailing-slash chains, old URL redirects stacked on top of each other
Couldn’t connect / HTTP 5xx	The server didn’t respond or returned a server error	Downtime, overloaded hosting, firewall or bot protection blocking Googlebot, maintenance mode
Can’t access robots.txt	Google couldn’t fetch your robots.txt file	robots.txt returning a server error or timing out
Hostname not resolvable	DNS lookup for the domain failed	Expired domain, DNS misconfiguration, removed subdomain
URL protocol or domain	The URL doesn’t start with http:// or https://, or isn’t on the verified domain	Relative URLs in the feed, product URLs on a different domain than the one claimed
Regional availability URLs	URLs with region_id aren’t crawlable	Region parameters returning errors or blocked pages

Google also asks that symbols in URLs be URL-encoded; a comma, for example, should be %2C. Unencoded characters can produce URLs that resolve to the wrong page or fail entirely.

How to confirm the cause

1. Open Products > Needs attention, select the landing page issue and note several sample products and their URLs.
2. Open each sample URL exactly as it appears in your data (including parameters) in a private browser window.
3. Use the URL Inspection Tool, which Google recommends for testing, with both desktop and smartphone fetches. This shows whether Googlebot gets the page, a redirect, an error or a block.
4. Check the redirect chain with a header checker or your browser’s developer tools and count the hops.
5. Fetch /robots.txt on the product domain and confirm it loads and doesn’t block product URLs.
6. Compare the domain in the product URL with the website claimed in Merchant Center.
7. Look for a pattern across samples: same collection, same URL format, same time window (an outage), or same variant parameter.

Fixing each error type

404 errors

• If the product still exists, restore its URL or update the link in your data to the current URL.
• If the product is discontinued, remove it from your data rather than leaving a dead link. If you only need to hide it temporarily, Google’s availability guidance points to the pause attribute (up to 14 days) or excluded_destination. See how to manage out-of-stock products.
• If a URL handle changed, update the feed source so the new URL syncs, rather than relying on a redirect.

Too many redirects

Google asks you to keep redirects to two or fewer. The best fix is to put the final URL in your data: correct protocol, correct host (www or not), correct trailing slash. Then collapse any redirect chains on the server so old URLs go straight to the final page in one hop.

Server errors and connection failures

• Check uptime and server logs for the time of the error.
• Check firewall, CDN and bot protection settings for rules that block or challenge Googlebot.
• Make sure maintenance mode isn’t left on for some pages or regions.
• If many products fail at once after a large feed upload, check whether the server can handle the crawl load. Google notes crawling is subject to server capacity.

robots.txt and DNS

• Make sure robots.txt returns successfully and doesn’t block Googlebot from product URLs.
• Check DNS records for the product domain and any subdomains used in product URLs, and confirm the domain hasn’t expired.

Protocol and domain

Every product URL must start with http:// or https:// and use the domain you verified in Merchant Center. Relative URLs and URLs on a staging, vanity or old domain will fail. Read more in the guide to verifying and claiming your website.

Regional availability URLs

If you use the regional availability add-on, URLs that include region_id must be crawlable. Test a sample for each region, not only the default URL.

Shopify and WooCommerce notes

Shopify

Google’s Shopify app setup article warns that with multiple domains, redirects or vanity URLs, the Google & YouTube app claims a site automatically, and the claimed domain may not match the domain in product URLs. That leads to approval issues. Google’s fix:

1. In Merchant Center, go to Settings > Business info and edit the online store.
2. Enter the domain used in your product URLs (it must be listed in Shopify under Settings > Domains).
3. Save, then select Change and Claim.
4. Let products sync automatically or trigger a manual sync.

More Shopify-specific issues are covered in Shopify Merchant Center troubleshooting.

WooCommerce

On WooCommerce, check permalink changes, security plugins that block bots, and caching or maintenance plugins. If you changed permalinks or moved to HTTPS, resync the product data so the feed carries the new URLs. See WooCommerce product feed errors.

After the fix: website checks and timing

1. Retest a few sample URLs with the URL Inspection Tool.
2. Request a website check from the issue in Merchant Center. Google says this can take up to 12 hours, and you can’t submit a new request during that time.
3. Give it time. Google says errors should disappear within a couple of days.
4. If issues persist, they are shown on the product’s details under Needs attention. Check those products individually.

Website checks are different from policy review requests. The disapprovals guide explains when to use each.

Preventing landing page errors

• Monitor uptime and alert on server errors, especially during sales and deployments.
• Allowlist Googlebot in bot protection and firewall rules, and re-check after security changes.
• Remove discontinued products from your data before deleting their pages.
• Use final URLs in your data; don’t rely on redirects.
• Keep the product URL domain and the claimed Merchant Center domain the same.
• After a migration, theme change or URL structure change, spot-check product URLs and the Needs attention tab.

When to get help

If errors come from hosting, CDN or firewall rules you don’t control, or affect many products after a migration, it helps to have someone trace the crawl path end to end. Our disapproval service handles landing page errors, and our technical SEO service covers redirects, crawl access and server issues. Google makes the final decision on reapproval.
