If you’re changing your Web site around and are afraid people will get lost if you move pages, create a user-friendly page to redirect people.
There is usually a single page that is the default for all of your “file not found” messages on your Web site. For mine, it's Error 404: File Not Found.
When someone clicks on a link to my site that is no longer there or has been moved, they get a friendly message that looks like this:
Now, isn’t that better than someone getting an unfriendly message generated by your Web hosting service? Simply find the file on your site and replace it with a more personal greeting.
Here's another cool trick. You'll notice that not only does my Error page display that the file no longer exists or has been moved. It also suggests an alternative link and provides a way to search the site. You or your Web guru can do this with these instructions and coding.
