What Is a 301 Redirect in SEO?
Definition
A 301 redirect is a permanent redirect that sends users and search engines from one URL to another. In SEO, a 301 redirect signals that a page has permanently moved and that ranking signals should be transferred to the new URL.
301 redirects help preserve traffic, rankings, and link equity when URLs change.
How a 301 Redirect Works
A 301 redirect works by:
-
Redirecting a request from an old URL to a new URL
-
Informing browsers and search engines that the move is permanent
-
Passing most ranking signals to the destination URL
When implemented correctly, users are automatically sent to the new page without interruption.
Why 301 Redirects Matter for SEO
301 redirects matter because they:
-
Preserve organic rankings
-
Maintain backlink value
-
Prevent broken links and 404 errors
-
Support clean site structure
-
Improve user experience during site changes
Without proper redirects, traffic and rankings can be lost.
Common Uses of 301 Redirects
301 redirects are commonly used when:
-
URLs are changed or renamed
-
Pages are merged or consolidated
-
A website is migrated to a new domain
-
HTTP is redirected to HTTPS
-
Duplicate pages are resolved
They are essential during technical SEO changes.
301 Redirect vs 302 Redirect
| Aspect | 301 Redirect | 302 Redirect |
|---|---|---|
| Redirect type | Permanent | Temporary |
| SEO signal | Passes ranking signals | Limited signal transfer |
| Use case | Permanent URL change | Short-term testing |
| Indexing | New URL indexed | Original URL retained |
Using the correct redirect type is important for SEO accuracy.
