After setting up Errorlytics, either with some copy-paste code or a plugin for WordPress or Drupal, you’ll begin seeing reports of all of the 404s popping up around your site. From there, Errorlytics lets you setup a rule for each 404 – such as redirecting a user who attempts to access that missing page to a specific piece of content on your site. You can also specify rules based on the referring page or a specific user agent.
So what’s the benefit of using Errorlytics as opposed to a generic 404 page? The main benefit would seem to be spotting opportunities within your 404 traffic. For example, if you’re a blog, and for some reason a popular article has been moved or deleted, being able to serve up links to relevant content as opposed to a generic 404 improves the odds that the visitor sticks around your website.
The bigger the website, the bigger these opportunities might be. Accordingly, Errorlytics offers a free account with minimal support (1 domain, 5 rules) and then offers tiered pricing for sites looking to get intense with their error handling. The top-level account, which is for 20 domains and unlimited rules, only runs $29.95/mo, so if you have an opportunity to gain tens of thousands of extra page views through better management of 404s, it might be worthwhile.
