You've probably encountered "404 Not Found" or "404 Error Page" before. This is actually the most common HTTP status code. 404 means "the server cannot find the requested page." Simply put, the URL you clicked doesn't exist.<\/p>

If it\u2019s a little hard to understand, it\u2019s like when you go to the supermarket to buy cheesecake, but the shelf is empty and the clerk doesn\u2019t tell you where to look. This \u201ccan\u2019t find\u201d situation is called 404 Not Found.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

The 404 Not Found error usually occurs when the server cannot find the resource the user requested.\ud83d\udc49 Simply put, 404 means "the server is working, but couldn't find what you were looking for."<\/span>There are three main common reasons:<\/p>

        404 error pages do not affect a website's SEO rankings, but if they are too numerous or handled improperly, they can reduce user experience and indirectly impact SEO results. But why do 404 errors indirectly impact SEO?<\/p>
