This post is about the error pages that people encounter when the page they are looking for does not exist. It explains how these pages are overlooked and how they can keep visitors on the site if done correctly. I liked looking at the examples they gave of effective and funny 404 pages. I think looking at the different examples shows how an effective 404 page would be beneficial in keeping visitors browsing through the website to find the information they are looking for instead of leaving the website completely.
