Fix Page Errors in HubSpot Page Performance Reports
When you see an unexpected error for one of your pages in the HubSpot Page Performance or SEO reports, it usually means the page is failing to load correctly or is being blocked for technical reasons. This guide explains the most common causes and how to fix them so your data stays accurate.
The information below is based on HubSpot’s official guidance and walks you through practical checks any marketer, admin, or developer can perform.
How HubSpot Page Performance Scans Work
Understanding how the scanning process works will help you pinpoint why a page shows an error in HubSpot reports.
- HubSpot uses an automated crawler to request the page URL.
- The crawler checks the HTTP status code and how the page loads.
- If the page does not return a successful response, HubSpot flags it with an error in Page Performance or SEO tools.
Because this crawler behaves like a visitor’s browser, any server or configuration issues that affect users can also cause report errors inside HubSpot.
Common Error Types Reported by HubSpot
Most time you will see one of a few recurring error patterns in HubSpot Page Performance:
- Soft 404 or real 404 errors
- Server-side errors
- Timeouts or blocked requests
- Redirection issues
Below are the most frequent situations and how to troubleshoot each one.
Soft 404 and 404 Errors in HubSpot Reports
A 404 means the requested page could not be found. A “soft 404” happens when the page visually looks like a not-found page but technically returns a 200 OK status code.
Soft 404: Page Looks Missing But Returns 200
In this case, HubSpot detects content that resembles an error or placeholder page while the server still reports a successful response.
Common causes include:
- Custom error pages that do not return proper 404 status codes.
- CMS templates that load a generic “not found” layout but keep status 200.
- Pages with extremely thin or empty content that appear to be broken.
How to fix it:
- Open the URL in a browser and confirm whether it is a real, live page.
- Use your browser’s developer tools or an HTTP status checker to verify the page status code.
- If the page is truly missing, configure your server or CMS so the not-found template returns status 404 instead of 200.
- If the page is valid, add meaningful content to avoid looking like an empty or placeholder page.
Real 404: Page Does Not Exist
If HubSpot shows a standard 404 error, the crawler received an explicit “not found” response.
How to fix it:
- Confirm that the URL is correct and not misspelled in your HubSpot content, menus, or links.
- If the page has moved, create a 301 redirect from the old URL to the new one.
- If the page was removed intentionally, update any internal links and remove it from navigation.
Server Errors in HubSpot Page Performance
Server errors usually appear when the page returns HTTP 5xx codes, which means something went wrong on the hosting side.
Typical Server-Side Issues
When HubSpot reports a server error, you might be dealing with:
- Temporary hosting outages or overload.
- Misconfigured caching or reverse proxies.
- Application errors in your CMS or custom code.
How to investigate:
- Open the page directly in a private browser window to see if you can reproduce the issue.
- Check your hosting or CMS status page for outages.
- Review recent code deployments, plugin updates, or theme changes that may have introduced errors.
- If you have server access, check the error logs for the time window when HubSpot attempted to crawl the page.
If the page is hosted outside of HubSpot, your web or IT team will typically need to correct the underlying server problem.
Blocked or Timed-Out Requests in HubSpot
Sometimes pages appear as errors in HubSpot Page Performance because the crawler cannot fully load the content or is blocked by site rules.
robots.txt and Security Blocks
The crawler can be prevented from loading a page if:
- Your robots.txt file disallows the path.
- Security tools or firewalls block the HubSpot user agent or IP ranges.
- Authentication is required to view the page.
How to fix it:
- Review your robots.txt file to confirm the page path is not blocked.
- Ask your security or IT team whether any firewall rules might be blocking marketing crawlers.
- Ensure public pages do not require login or IP allowlisting to render.
Connection Timeouts and Slow Pages
If a page is extremely slow, the HubSpot crawler may time out before it finishes loading, which can surface as an error or an incomplete scan.
Ways to improve this:
- Optimize large images, videos, and scripts.
- Use caching and a content delivery network (CDN) if available.
- Minimize heavy third-party scripts and tags that block rendering.
Redirect and URL Issues Detected by HubSpot
Redirects can also trigger warnings or errors in HubSpot Page Performance when configured incorrectly.
Broken or Misconfigured Redirects
Problems often include:
- Redirect loops (URL A redirects to B, which redirects back to A).
- Redirect chains (A → B → C → D instead of A → D).
- Redirects that lead to 404 or 5xx pages.
How to fix redirect-related errors:
- Check the redirect path using your browser or a redirect checker.
- Consolidate long chains into a single direct 301 redirect where possible.
- Ensure final destination URLs are valid, live pages.
Special Considerations for HTTPS and Mixed Content
Some pages flagged as errors in HubSpot may still appear to load, but with browser warnings related to security.
Key checks:
- Confirm the page loads over HTTPS without certificate warnings.
- Remove or update any insecure HTTP assets (images, scripts, iframes) on HTTPS pages.
- Update hard-coded URLs within your templates or modules to use protocol-relative or HTTPS links.
Verifying Fixes in HubSpot Page Performance
Once you have corrected the underlying issue, you should confirm that the error clears from your HubSpot reports.
- Open the page in a browser and ensure it loads correctly with the right status code.
- Check your site with a standard SEO crawler to confirm there are no 4xx or 5xx errors.
- Return to the HubSpot Page Performance tool and allow time for the next crawl.
- Re-check the specific page report after HubSpot rescans it.
If the problem persists after you have verified that the page is healthy, compare your setup against the official reference documentation at this HubSpot help article and consult your developer or administrator.
