404 Error
A 404 error is an HTTP response code indicating that the requested URL cannot be found on the server, shown to visitors and search engines when a page does not exist.
Full Definition
404 errors occur when a URL is deleted, renamed, or never created, and no redirect is in place. For visitors, a 404 page is a dead end — the browsing session typically ends there. For Google, a page returning a 404 is removed from the index over time. Dealership sites accumulate 404 errors steadily as sold vehicles are removed from inventory, old model year pages are deleted, and URLs change during platform updates without corresponding redirects.
Why It Matters for Your Dealership
A dealership site with hundreds of 404 errors from deleted inventory and old model pages is leaking ranking authority and frustrating buyers who land on dead pages. Both problems reduce lead volume and signal poor site health to Google's quality systems.
In Practice
Dealership sites accumulate 404 errors steadily as sold vehicles are removed from inventory, old model year pages are deleted, and URLs change during platform updates without corresponding redirects.
