Look, it’s great to have a customized “404 – Page Not Found” error message for your website. Although you don’t want your visitors to see this page if you can help it, it’s a professional touch for those times when a link gets broken or the address to a deleted page continues to show up in Google search results. But don’t use this message to say that “we have recently redesigned our website to better serve our visitors.”
Why? Because if I’m reading your custom 404 error message, that means something went wrong. You either moved, renamed, or got rid of the page I was looking for, and instead of giving me the information I was hoping to find, you give me an ironic error message that brags about how you improved your website to serve me better.
And definitely don’t follow it up with “we apologize for any inconvenience.” It’s a musty old corporate phrase that doesn’t mean anything anymore–if it ever did. Isn’t it a given that your visitors will feel inconvenienced when they click on a broken link?
Just say the page couldn’t be found. Offer some links that direct people to helpful sections of your website. I’m sure you can think of ways to make a 404 error page even better, but at least cover the basics without diving into a bag of weaselly stock phrases.
