Why You’re Seeing This Warning in Google Merchant Center

Managing your Google Merchant Center (GMC) account effectively is crucial for keeping your products visible in Shopping ads and free listings. If you’ve spotted the “Unavailable Desktop and Mobile Landing Page” warning in Google Merchant Center, you’re not alone. Although this issue doesn’t immediately disapprove your products, it can quietly damage your visibility—and your conversions—if left unchecked.

This warning shows up when Google is unable to access your product landing pages on both desktop and mobile devices. Over time, unresolved access issues can lead to product removals, lost traffic, and wasted ad spend.

At FeedSpark, we know that even small technical errors can make a big impact. That’s why, as part of our fully managed service, we proactively monitor feed health and landing page accessibility to help our clients stay compliant and competitive.

What Causes the ‘Unavailable Desktop and Mobile Landing Page’ Error in Google Merchant Center?

At FeedSpark, we’ve helped merchants across fashion, automotive, and lifestyle categories troubleshoot this warning. Here are the most common triggers:

  1. Temporary Website Downtime
    Maintenance or server hiccups may cause your site to go offline briefly when Google tries to crawl it.
  2. Server Errors (404, 500, etc.)
    If your server returns an error page, Google can’t access or index the content.
  3. Blocked Crawlers
    Your robots.txt file or firewall settings might unintentionally block Googlebot.
  4. Slow Page Load Speeds
    Pages that take too long to load can time out, triggering this warning.
  5. Redirect Errors
    Misconfigured redirects (e.g. broken 301s) might send Google to an invalid page—or no page at all.

How to Fix the ‘Unavailable Desktop and Mobile Landing Page’ Warning

At Feedspark, we provide front-end monitoring and expert recommendations to help merchants resolve GMC warnings before they result in lost sales. Here’s how to address this issue:

At FeedSpark, we specialise in spotting and resolving feed issues before they spiral into lost sales. If you’ve received this warning in Google Merchant Center, here’s how to take action:

  1. Check Website Uptime
    Start by using a website monitoring tool like UptimeRobot or Pingdom to track any outages. Even short periods of downtime can trigger this warning if Google crawls your site during that window.
  2. Investigate Server Errors
    Look into your site’s error logs. Are any product URLs returning 404 (not found) or 500 (server error) messages? These need to be corrected to ensure smooth access for Googlebot.
  3. Review Robots.txt and Firewall Settings
    Head to yourwebsite.com/robots.txt and double-check that Googlebot is allowed to crawl your product pages. Additionally, ensure that firewalls or security settings aren’t accidentally blocking crawlers.
  4. Test URLs in Google Search Console
    Use the URL Inspection Tool to check whether Google can access and render your landing pages properly. This also helps identify whether the problem is mobile-only, desktop-only, or both.
  5. Improve Page Load Speeds
    Slow pages can time out during Google’s crawl. To prevent this, test your URLs using Google PageSpeed Insights and optimise images, enable compression, and reduce server response time.
  6. Fix Redirect Chains or Broken Redirects
    Redirects that loop or break mid-flow confuse crawlers and users alike. Audit all redirect paths and ensure that each product URL points cleanly to a valid, indexable page.
