Why HTTP Status Codes and Errors Are Important for Search Engine Optimization? SEO of course!
Search engine bots see HTTP status codes when they crawl your site. In some cases, these messages can affect whether and how your pages are indexed and how search engines perceive the health of your site.
In general, 100- and 200-level HTTP status codes won’t have much impact on SEO. They ensure that everything is working as it should on your site and that search engine bots are moving on. However, they won’t improve your rankings.
For the most part, it’s the top-level codes that matter for SEO! 400 and 500 level responses can prevent bots from crawling and indexing your pages. Too many of these errors can also indicate that your site is not high quality and could potentially lower your rankings.
