404 Error
A 404 error is a website status code indicating that a webpage cannot be found on the server. This is typically because the page has been removed or moved, but the old URL hasn’t been redirected to the new location.
404 errors should be monitored for and removed when found, but it’s often tough to catch all of them on large or older websites. Designing a 404 page that apologizes to the user in an amusing way and provides them with some resources to help them find what they’re looking for can be a great way not to lose credibility on your site.
