HTTP without WWW
http://example.com/
There are other ways to check
We invite you to familiarize yourself with them.
Methodology: This check follows wSEO methodology 1.1. How the assessment works
Independent primary-hostname verification
Confirm that WWW and non-WWW do not behave as two websites
Test the alternative hostname on a real internal page. The correct result is one permanent hop to the same page on the primary domain.
- a 301 or 308 response;
- the path and query string are preserved;
- no intermediate hop or loop.
How to interpret the result
| Situation | Level | Action |
|---|---|---|
| Both versions open separately | Critical | Select the primary hostname and configure a redirect. |
| The alternative does not exist | Yellow | No duplicate; a fallback entrance is recommended. |
| One hop to the primary version | Correct | No repair is required. |
Browser check
- Open a private window.
- Add or remove WWW on a real internal page.
- Confirm the primary hostname and preserved path.
- Capture the original and final addresses.
Online checker
- Open httpstatus.io.
- Enter the complete alternative URL.
- Expand the response chain.
- Save the check with the code and final URL.
Test all four variants
HTTP with WWW
http://www.example.com/
Both HTTPS variants
The primary returns 200; the alternative leads directly to it.
DevTools
- Open Network and enable Preserve log.
- Visit the alternative URL.
- Select the first request.
- Check Status Code and Location.
Terminal
curl -sS -o /dev/null -D - \ "https://www.example.com/contact"
curl -sS -L -o /dev/null \
-w "Final: %{url_effective}\nCode: %{http_code}\nRedirects: %{num_redirects}\n" \
"https://www.example.com/contact"Good-result checklist
- the alternative returns 301 or 308;
- it leads to the selected HTTPS hostname;
- path and parameters are preserved;
- there is one hop;
- the final page returns 200;
- there is no hostname loop.
If results disagree, repeat the test in a private window and by a second method. Do not order a repair until two independent checks confirm the issue.
