404 Error
The response a server gives when a page doesn't exist. A few 404s are normal; hundreds of internal links pointing at dead pages waste crawl budget, leak ranking authority, and dead-end real shoppers. Deleted products and renamed categories are the usual culprits on stores — each one should redirect somewhere useful.
