Troubleshooting Broken XHR Resources Affecting SEO

2 responses to “What solutions exist for fixing broken XHR resources that hinder search bot rendering?”

1. When dealing with broken XHR resources that are preventing search bots from rendering a page properly, it’s essential to address a few key aspects. These involve debugging the issues related to redirects, missing resources, and ensuring the server responses are optimized for search engines like Googlebot. Here’s a step-by-step guide to help you resolve these issues:

   Step 1: Diagnose the Problem

   1. Check Google Search Console (GSC): Start by using Google Search Console to inspect the affected URL. It can highlight issues related to crawling and rendering.

   2. Use Developer Tools:

   3. Open your browser’s Developer Tools (usually F12 or Ctrl+Shift+I on Windows, Cmd+Opt+I on Mac).
   4. Navigate to the Network tab.
   5. Reload the page and filter for XHR/fetch requests to monitor the requests and responses.

   6. Identify any failed requests or unexpected redirects (302 in your case).

   7. Logs and Server Configuration:

   8. Review server logs to identify any server-side issues.
   9. Check if there are misconfigurations causing these 302 redirects.

   Step 2: Fix Redirect and Resource Loading Issues

   1. Analyze Redirects:
   2. Ensure that redirects are intentional and the target URLs are correct.

   3. If 302 (temporary) redirects are unnecessary, consider using 301 (permanent) redirects where appropriate, particularly for resources that need permanent redirecting.

   4. Resource Availability:

   5. Confirm that all required resources (JavaScript, CSS, images) are accessible. Use direct URLs to check if they lead to valid resources.
   6. If certain resources are blocked by robots.txt, adjust rules to allow essential resources to be accessed by Googlebot.

   Step 3: Optimize for Googlebot

   1. Check User-Agent Specific Behavior:
   2. Ensure there’s no server-side logic preventing Googlebot from accessing XHR resources.

   3. Use tools like Fetch as Google in GSC, or other third-party services to simulate Googlebot’s request and see the actual content served.

   4. JavaScript Execution:

   5. If the content is dynamically-loaded via JavaScript, ensure that your site can fall back to server-side rendering (SSR) or pre-rendering to provide initial content to search bots.
   6. Consider using services like

2. It’s great that you’re taking a meticulous approach to troubleshooting XHR resource issues—these can be tricky but are vital for optimal SEO performance. From the symptoms you’ve described, it seems that the issue could be a result of several overlapping problems, particularly concerning the HTTP 302 redirects.

   Here are a few suggestions that might help:

   1. **Check Redirects**: Investigate the paths leading to the broken XHR requests. Ensure that the 302 redirects are not causing a loop or unnecessary delay. Sometimes, a 301 permanent redirect might be more appropriate depending on your content’s lifecycle.

   2. **Examine Network Conditions**: Since you mentioned the initiator processes through mpulse, verify if there are any timeouts or network inconsistencies affecting the requests. Tools like Chrome DevTools can help you analyze the performance metrics of these requests.

   3. **Review the Robots.txt and Meta Tags**: Ensure that there are no restrictions in your `robots.txt` file or `` tags that could prevent Googlebot from accessing the specific XHR endpoints.

   4. **Test with Fetch as Google**: Use the ‘URL Inspection’ tool in Google Search Console to see how Googlebot processes your page, which can give you insights into how the XHR requests are being resolved during the crawling phase.

   5. **Implement Server-Side Rendering (SSR)**: If these XHR resources are critical for rendering your page, consider switching to server-side rendering to ensure that the full content is available to search
