WWW redirect checker: do http, https, www and non-www all reach one address?
In short: Paste domains and see, for each, where http://, https://, http://www. and https://www. end up, the redirect codes on the way, and whether the site is Consistent, uses temporary redirects, has one version that fails, is split into two copies, or doesn't send visitors to HTTPS. Limit: It tests the home page only; deeper paths can redirect differently.
A www redirect checker opens a domain four ways, http and https with and without www, and follows each to where it ends. Paste one domain or up to 100 (500 after a Google sign-in): each gets Consistent, Temporary redirects, One version fails, Split: two versions, No HTTPS redirect or Unreachable, with every redirect code and the final address.
Price: this tool is free. Checking a whole email list is from $9/mo, and the first 100 checks are free with Google, no card. See pricing

Checking redirects across a portfolio of domains?
- Over 500 domains? Run them in batches of 500 when signed in and download the CSV after each.
- For domains that fail, see whether they're parked or down with the bulk website status checker.
- Emailing from or to these domains? Check the address list at /verify. The first 100 email checks are free with a Google sign-in, no card.
How do I check that www and non-www redirect to the same URL?
- Paste one domain or a list, one per line: up to 100 a run, or 500 after a free Google sign-in. www. is removed, since both versions are tested.
- Press Check redirects. Each of the four start URLs is opened and followed through up to five redirects.
- Read where each version ends, the redirect codes (301, 302, 307, 308) and the notes on what to fix.
- Download the CSV with one column per version.
Example
- You enter
- Three domains:
acme.example,globex.exampleandinitech.example. - You get
acme.exampleConsistent: http, https, www and non-www all reach https://www.acme.example through 301s.globex.exampleSplit: two versions: https://globex.example and https://www.globex.example both answer 200 without redirecting.initech.exampleNo HTTPS redirect: http://initech.example stays on HTTP. Download the CSV.- Limits
- Up to 100 domains a run without an account and 500 when signed in with Google. Home page only; HTTP redirects only.
Why should every version of a domain redirect to one address?
http://acme.com, https://acme.com, http://www.acme.com and https://www.acme.com are four different URLs to a browser and a search engine. If two of them serve the page without redirecting, the site exists twice: links and signals split between the copies, and search engines pick one as canonical, which may not be the one you'd choose. Google's guide to duplicate URLs lists redirects as a strong signal for which copy is canonical.
Which host you pick, www or bare, doesn't matter much. What matters is that all four reach it, over HTTPS, in as few hops as possible. A missing version is the other common fault: www with no DNS record, or a bare domain whose certificate only covers www, gives some visitors an error page instead of the site.
301, 302, 307 or 308: which redirect should a site use?
A permanent move should use 301 or 308 (RFC 9110 sections 15.4.2 and 15.4.9). 302, 303 and 307 say the move is temporary, so a search engine may keep the original URL as the one it shows. 308 and 307 also promise the method stays the same, which matters for form posts, not for a home page. Google's redirect docs treat 301 and 308 as permanent and 302 and 307 as temporary.
Plain HTTP should always end on HTTPS. Once it does, the Strict-Transport-Security header (RFC 6797) tells browsers to skip the HTTP hop on later visits; the security headers checker shows whether it's set.
What does each status mean?
| Status | What the four versions do | Fix |
|---|---|---|
| Consistent | All reach one HTTPS address through 301 or 308 redirects. | Nothing. |
| Temporary redirects | All reach one HTTPS address, but a hop is 302, 303 or 307. | Make the redirect permanent (301 or 308). |
| One version fails | The rest agree, but one doesn't answer (often www with no DNS record). | Add the DNS record and certificate, then redirect it. |
| Split: two versions | They end on different hosts, so the site is served twice. | Redirect one host to the other. |
| No HTTPS redirect | An http:// version stays on HTTP. | Redirect HTTP to HTTPS. |
Who uses this tool, and for what?
- SEO teams
- Find sites served on both www and the bare domain after a migration.
- Web agencies
- Confirm every client domain sends all four versions to one HTTPS address after launch.
- Domain portfolio owners
- Check that redirects on old brand domains are permanent, not 302.
- IT teams
- Catch a www that stopped answering after a DNS or certificate change.
What can’t this tool tell you?
- It tests the home page only; deeper paths can redirect differently.
- HTTP redirects only; JavaScript and meta refresh redirects aren't followed.
- Sites that answer differently by country, device or bot detection may show a different result elsewhere.
- Up to 100 domains a run without an account and 500 signed in.
Common questions
- Should I use www or the bare domain?
- Either works. A bare domain is shorter; www can be a CNAME, which some hosts and CDNs need. Pick one and redirect the other three versions to it.
- How many redirects does it follow?
- Up to five for each version, the same cap as the other website tools here. A chain longer than that is reported as failing.
- Does it follow JavaScript or meta refresh redirects?
- No. It follows HTTP redirects (3xx with a Location header), the kind search engines treat as the strongest signal.
- Why is one version reported as not answering?
- Usually no DNS record for www, or a certificate that doesn't cover that name, so HTTPS fails. The note under the domain gives the reason.
- Can I check many domains at once?
- Yes. 100 domains a run without an account and 500 after a free Google sign-in, with a CSV.
- Is the www redirect checker free?
- Yes, it's a free tool with no card. Four requests per domain.
