What Is 301 Redirect?
A 301 redirect is an HTTP status code sent by a web server indicating that a requested URL has been permanently moved to a new destination. It automatically forwards users and search engine crawlers to the new page while transferring backlink equity, ranking signals, and authority from the original URL.

Why 301 Redirect Matters
When you delete or move a page without a redirect, visitors and search engine bots encounter a 404 error. This disrupts the user experience and causes search engines to de-index the old page, wiping out accumulated authority and inbound link equity.
Mechanics
How 301 Redirect Works
When a browser or crawler requests a URL configured with a 301 redirect, the web server returns a 301 Moved Permanently response header along with the new destination URL.
The browser immediately loads the new location without manual user intervention. Search engines process the status code by replacing the old URL in their index with the new URL and transferring the original page’s PageRank and historical signals.
Application
301 Redirect Example
If an eCommerce store updates an address from example.com/mens-running-shoes to example.com/shoes/mens-running, setting up a 301 redirect routes anyone clicking an old external backlink straight to the new page without losing organic search rankings.
Advantages
Benefits Of A 301 Redirect
- Preserves Link Equity: Passes PageRank and backlink signals from the old page to the target URL.
- Maintains Search Rankings: Prevents sudden drops in organic traffic during site updates and domain changes.
- Improves User Experience: Ensures users reaching old or outdated links do not land on broken 404 pages.
- Fixes Duplicate Content: Resolves canonicalization issues by routing HTTP to HTTPS or non-WWW to WWW versions.
Pitfalls
301 Redirect Mistakes
- Redirect Chains: Linking multiple redirects in a series (Page A to Page B to Page C), which slows page load speed and wastes crawl budget.
- Redirect Loops: Pointing two pages at each other, causing an infinite loop that breaks access.
- Using 302 Instead of 301: Using temporary redirects for permanent URL changes, preventing search engines from transferring authority.
- Irrelevant Bulk Redirects: Redirecting all deleted pages to the homepage, which Google often treats as soft 404 errors.
