What is 502 bad gateway error?

502 Bad Gateway error is an HTTP status code that indicates that the server encountered an error while attempting to handle the request.

If you attempt to visit a web page at the same time that one web server receives an erroneous answer from another web server, you will receive a 502 Bad Gateway Error. In most cases, the issue is within the website itself, and there is nothing that can be done about it.

This can be caused by a number of different issues, such as an incorrectly configured web server, misconfigured client software, or a broken link in the chain of referrals.

What is a 502 Bad Gateway Error?

When a server encounters the error code 502 Bad Gateway, it indicates that the server has specifically received an incorrect response from an inbound server.

Your web browser will communicate with a web server to make a request each time you visit a website. After the request is received and processed by the web server, the server will then send back the resources that were requested along with an HTTP header and an HTTP status code.

Unless something goes wrong, an HTTP status code is not often observed by the client. The error message is essentially the server’s way of informing you that something is wrong and providing you with the necessary instructions to diagnose the problem.

5xx Errors Impact on SEO

Unlike 503 errors, which are used for WordPress maintenance mode and instruct Google to return at a later time, a 502 error can have a severe impact on SEO if not corrected immediately. If your site is only down for 10 minutes and is continuously crawled, the crawler will often simply receive the page sent from cache. Google may not even have a chance to re-crawl it before it goes back online. You’re perfectly alright in this circumstance.

SEO is all about making sure your website is ranking high in search engine results pages (SERPs). Achieving this can be challenging, but thankfully, there are a few things you can do to help minimize the chances of encountering 5xx errors.

Check Your Website’s Structural Integrity

A well-built website should have clean and organized code, as well as properly nested HTML tags. Avoid using excessive whitespace, and make sure all images are properly tagged and optimized for SEO. 5xx errors can arise when elements aren’t placed where they should be or when code is messy or unorganized.

Minimize Server Response Time

Server response time is critical for the optimization of your website. Slow response times can cause your site to rank lower in search engine results pages (SERPs).

Although they may not seem like a huge deal, 5xx errors can seriously impact how well your website ranks in search engine results pages (SERPs). In fact, research has shown that up to 70% of lost traffic comes from websites with at least one 5xx error.
