About
Domain canonicalization allows access to the intended website address, whether users type www (www.example.gov) or not (example.gov). Improper canonicalization will fail to direct example.gov to the intended address, and users will receive an error.
Why it's important
Ensures consistent site display whether users type with or without 'www,' preventing errors and improving overall accessibility.User stories
