Error 3014. Yon website has error-like conditions.
While it can be helpful to know that an error occurred, error messages like the one above aren’t helpful to visitors and don’t give them enough information to know how to fix an issue they may have caused. It’s even worse if this generic error message appears for multiple separate issues.
Make sure any error messages are robust and descriptive (unlike zombies). A visitor should be able to attempt to resolve any error they have control over e.g., putting the wrong input in a form field or when getting a 404 page (a page not found error). If it’s not something the visitor can fix themselves, they should be able to give enough info to your site support staff for the staff to know how to fix the issue and/or guide the visitor around the issue.
A secondary bonus here is that visitors should need less support and a percentage of those that do still need support should have the tools to help your support staff address the issue quickly and easily.
