404 Page Not Found: What It Is and Why Web Developers Care.

The 404 Page Not Found problem is one of the biggest problems web designers can face. Even if it doesn’t affect your SEO, when the page cannot be retrieved, it causes a poor user experience that can impact your business.

What is 404 Page Not Found?

Have you ever accessed a website and found nothing but “404 Page Not Found” on the page? Since the page seemingly no longer exists, you may wonder why it still says “Page Not Found”. In fact, 404 Page Not Found indicates an error which means that the URL can’t be found or the file on that page can’t be retrieved. In simpler words, the link is broken.

Even though 404 Not Found may not impact website traffic, it can cause you to miss business opportunities. Since the web page isn’t working, customers may lose interest in your products and turn to your competitors. Also, you may pay the advertising costs for nothing if you place ads that direct to a 404 Error Page, for example.
