HTTP Status Codes Every Website Owner Should Know
Recognize successful, redirected, missing and failed requests when diagnosing a website. Include the exact status, URL and time in a useful technical support request.
HTTP status codes summarize what happened to a request. They are useful evidence for browsers, search engines, monitoring tools and support teams. In practice, HTTP status codes works best when the outcome and owner are explicit.
The decision behind the task
Recognize successful, redirected, missing and failed requests when diagnosing a website. The right depth depends on risk, audience and the people responsible afterward.
A clear checklist
- 200 success: Use it when the requested public resource is returned normally.
- 301 or 308 redirect: Use a permanent redirect when a resource has a durable new address.
- 404 or 410 missing: Return an honest missing status instead of a friendly page with a success code.
- 500-series failure: Investigate server, gateway or dependency errors through logs and timing.
Treat the checklist as a decision aid, not a substitute for context. Ownership, evidence and a safe way back matter whenever the work affects customers or business data.
Where teams get stuck
Do not mask every failure with a 200 response; clients cannot distinguish success from an error page.
A sensible next step
Include the exact status, URL and time in a useful technical support request.
