How does Technical SEO Audit check server errors?

A Technical SEO Audit helps identify server errors by checking how a website responds to requests from browsers and search engine crawlers. It examines HTTP status codes, server responses, page accessibility, and crawling issues. Finding these problems early helps website owners maintain website performance and ensure important pages remain accessible.

What Are Server Errors in SEO?

Server errors occur when a web server cannot successfully complete a request for a particular page or resource. Instead of delivering the expected content, the server returns an error response.

The most common server errors belong to the HTTP 5xx status code category.

For example, when someone visits a website and receives a 500 Internal Server Error message, it usually means something has gone wrong on the server side.

Common server errors include:

• 500 Internal Server Error: A general problem prevents the server from completing a request.

• 502 Bad Gateway: A gateway or proxy server receives an invalid response from another server.

• 503 Service Unavailable: The server is temporarily unable to handle requests.

• 504 Gateway Timeout: A server does not receive a timely response from another server.

These errors can affect individual pages or sometimes an entire website.

How Does a Technical SEO Audit Check Server Errors?

A Technical SEO Audit uses website crawling, HTTP response analysis, and performance monitoring to identify server-related problems.

Here are the main methods used during the process.

Checking HTTP Status Codes

One of the first steps is checking the HTTP status codes returned by website pages.

SEO crawling tools request different URLs and record the responses received from the server. If a page returns a 5xx status code, the audit identifies it as a server error.

This information helps SEO professionals understand which pages are inaccessible and whether the problem affects multiple URLs.

Crawling Important Website Pages

Website crawling helps discover server errors across different sections of a website.

An SEO crawler follows internal links and checks the responses returned by each page. If several important pages return server errors, the audit can highlight a wider technical problem.

This is particularly useful for large websites with hundreds or thousands of URLs.

Testing Server Availability

A Technical SEO Audit can also examine whether a website remains accessible during repeated requests.

If the server frequently becomes unavailable, visitors and search engine crawlers may experience inconsistent access.

Monitoring server availability helps identify recurring downtime and temporary connection problems.

Reviewing Server Response Times

Slow server responses can sometimes indicate underlying technical issues.

An audit may measure how long the server takes to respond to requests. Consistently slow responses can point toward server overload, database problems, or inefficient hosting configurations.

However, a slow response does not automatically mean a server error has occurred.

Why Are Server Errors a Problem for SEO?

Server errors can create several problems for website performance and search visibility.

Search Engines Cannot Access Important Pages

When search engine crawlers repeatedly encounter server errors, they may struggle to access website content.

This can delay crawling and make it harder for search engines to process important pages.

Visitors Experience Website Problems

Visitors expect website pages to load when they click a link. If they repeatedly encounter error messages, they may leave and look for information elsewhere.

This creates a poor user experience.

Important Content May Become Temporarily Unavailable

Server errors can prevent visitors from accessing product pages, service information, blog posts, and other valuable content.

For businesses, this may interrupt customer journeys and affect important website activities.

What Causes Server Errors?

A Technical SEO Audit can help identify affected URLs, but finding the exact cause may require additional server-side investigation.

Common causes include:

Server Overload

When a server receives more requests than it can handle, it may struggle to respond correctly. This can happen during traffic spikes or when hosting resources are insufficient.

Incorrect Server Configuration

Misconfigured server settings, permissions, or software components can cause pages to return error responses.

Database Connection Problems

Websites that depend on databases may experience errors when database connections fail or become overloaded.

Hosting Provider Issues

Sometimes the problem comes from the hosting environment rather than the website itself. Hardware failures, maintenance, and network interruptions can affect server availability.

How Can You Fix Server Errors Found During an Audit?

Once the audit identifies server errors, website owners should investigate the affected URLs and determine the underlying cause.

Contact Your Hosting Provider

If the server experiences repeated downtime or widespread errors, contact your hosting provider. They can investigate server resources, network problems, and infrastructure issues.

Review Server Logs

Server logs provide useful information about requests, failed operations, and application problems.

Developers can review these logs to understand what happened when a particular URL returned an error.

Check Website Plugins and Themes

On WordPress websites, outdated or incompatible plugins and themes can sometimes create server-side problems.

Review recent updates and investigate whether a specific component is causing the issue.

Improve Server Resources

If the website regularly experiences overload, upgrading hosting resources or optimizing database operations may help improve stability.

Which Tools Help Identify Server Errors?

Several tools can support server error detection during a Technical SEO Audit.

• Google Search Console: Helps identify crawling and server connectivity problems reported by Google.

• Screaming Frog SEO Spider: Crawls website URLs and reports HTTP status codes, including 5xx errors.

• Sitebulb: Provides website crawling and technical SEO reporting features.

• Server Logs: Help developers investigate the underlying causes of failed requests.

Using these tools together provides a clearer picture of website accessibility and server health.

Conclusion

A Technical SEO Audit checks server errors by crawling website pages, analyzing HTTP status codes, reviewing server responses, and identifying inaccessible URLs. It helps website owners understand whether technical problems are affecting individual pages or the entire website.

The Technical SEO Audit server errors process is important for maintaining website accessibility and supporting effective search engine crawling. By investigating server logs, reviewing hosting resources, and correcting configuration problems, website owners can reduce server errors and provide visitors with a more reliable browsing experience.
