Empty states can occur when there is an error, an incorrect URL is searched, or an old URL is used.
Well-designed empty states ensure that your products look professional at all times and that you avoid losing potential customers. The written explanation should help the user understand what they need to do next. This could be anything from creating a profile to adding other users to a network. This written guide should be concise so that the user can easily take the next appropriate step.
For example, you could use “We can’t seem to find the page you are looking for. Here are a few helpful links instead."
You could provide links to the more common areas of the application here. Ideally, some well-designed visual content should also be used.
