Digital Agencies are alerting Webmasters to a subtle yet important Search Engine Optimization problem: Websites incorrectly signaling a “200 OK” status code when a page doesn’t exist. This practice, while seemingly benign, can severely impact a site’s search ranking and user experience. Teh issue arises when a server returns a triumphant response, even when a requested page is unavailable, misleading both users and search engine crawlers.
The Problem With Incorrect Status Codes
Typically, when a user or a search engine bot requests a page that is not found, the server should respond with a “404 Not Found” error. This signals that the resource is unavailable. A “200 OK” response, though, indicates everything is functioning normally, even though it isn’t. This miscommunication leads to several problems.
Search Engines like Google rely on these status codes to understand the structure and content of a website. When a 200 status code is sent for a non-existent page, search engines may continue to index it, wasting crawl budget and perhaps diluting the site’s overall authority. This can lead to lower rankings for legitimate pages. According to a recent study by Search Engine Journal, incorrect status codes contribute to approximately 15% of indexing errors.
How This impacts User Experience
Users encountering a 200 status code for a missing page might not immediately realize there’s an error. Instead of seeing a clear “Page Not Found” message, they may be shown a generic, or worse, incorrect page, leading to frustration and a negative user experience. This can increase bounce rates and decrease time on site – both factors that negatively affect SEO.
Did You Know? A high bounce rate signals to search engines that your content is not relevant or engaging, potentially lowering your search rankings.
Identifying and Fixing the Issue
Identifying these incorrect responses usually requires technical auditing tools. Webmasters can use tools like Google Search Console, Screaming Frog, or Sitebulb to crawl their websites and identify pages returning a 200 status code when they should be returning a 404.
Once identified, the fix involves adjusting server-side configurations to ensure that a 404 status code is returned when a page is not found.This might require modifying the `.htaccess` file on an Apache server or adjusting server blocks on an Nginx server.
| Status Code | meaning | SEO Impact | User Experience |
|---|---|---|---|
| 200 OK | Page found and served successfully | Wasted crawl budget, diluted site authority | Potential confusion, negative experience |
| 404 Not Found | Page not found | Signals missing content, allows search engines to re-crawl | Clear error message, possibility for redirection |
Pro Tip: Implement custom 404 pages that offer helpful suggestions, such as a site search or links to popular content, to turn a negative experience into a positive one.
The Importance of Proper Implementation
Ensuring correct status code implementation is a crucial aspect of technical SEO. It demonstrates a commitment to both search engine crawlers and users, fostering trust and improving overall website performance. Regularly auditing your site for these errors is an essential part of maintaining a healthy online presence.
What steps will you take to audit your website for this issue, and how do you plan to improve user experience on your 404 pages?
Staying Ahead: Ongoing Website Maintenance
Maintaining a healthy website goes beyond fixing individual errors, it’s an ongoing process. Regularly updating your content, monitoring website performance, and staying informed about search engine algorithm changes are all critical components of success. Consider implementing a robust monitoring system to proactively identify and address potential issues before they impact your site’s visibility and user experience.
