Impact of 500 Internal Server Error on SEO

When Google gets 5xx error on a site, it can lower a page's ranking or drop it from the index, as such errors may cause a negative user experience. In fact, these errors have the most harmful impact on SEO.

They are the most difficult errors to fix. It's hard to find the exact problem they indicate and its simplest solution. Also, often you can't solve these problems by modifying the page code and you may need to apply to developers or server administrators for help.

Still, you should, and even must, fix them as search engines don't like 5xx errors at all. A search engine can't crawl and analyze your site if it gets 500 error and 503 error. This also means that 500 error codes can cause poor user experience and negatively impact on your site's ranking and indexing.

Of course, your ranking will not drop as soon as a 5xx error appears. There have to be multiple instances of 503 responses over a week or two before the page is removed from Google's index. And here you have time to fix them.

If your site is only down for say 10 minutes and it's being crawled consistently a lot of times the crawler will simply get the page delivered from cache or Google might not even have a chance to re-crawl it before it's back up. In this scenario, you're completely fine.

However, if the site is down for an extended period of time, say 6+ hours, then Google might see the 500 error as a site level issue that needs to be addressed. This could impact your rankings. If you're worried about repeat 500 errors you should figure out why they are happening to begin with.

Conclusion
Like we alluded to above, the 500 internal server error is not an issue on your side, rather it is a server-side problem. This means the problem is not with your device or internet connection but with your web server. Still, you can try some fixes at your end also, maybe they will fix the error. But in most cases, you need to follow the platform-specific troubleshooting mechanisms and fixes to get the error fixed.
