This could be a big deal (but it isn’t) and here’s why.
A 404 means you followed a bad link and our web server doesn’t know what content to serve. Many site owners are oblivious to bad links to their site because they don’t actually have Google Analytics running on their 404 pages, nor do they flag them specially in Analytics.
So for many brands, whatever you did to end up here, could be a recurring problem with SEO and user experience implications. Thankfully, we flag 404s in Google Analytics with a special event so it’s easy to filter and identify when people like you end up on this page. We can then reactively go and put a redirect in place to prevent the issue moving forward, and see if there is referrer information to put a proper fix in place.
This is something you can do as well. Just work with your web developer to send a special event to Analytics when the server serves up a 404 error instead of a real page.
