TL;DR: A permanent forwarding rule that sends users and search engines from one URL to another while passing on most ranking signals.
In a nutshell
When you change a URL, a 301 redirect tells browsers and Google the move is permanent and to update their index accordingly. It preserves backlinks, rankings, and user journeys, so traffic does not vanish overnight. Common uses include site migrations, switching to HTTPS, or consolidating duplicate pages after a rebrand.
Quick answer: A 301 redirect is a permanent HTTP status code that tells browsers and search engines that a URL has moved to a new location. The 301 is the standard for any permanent URL change because Google passes ranking signals through it almost completely. Use it whenever you move, restructure, or rename URLs. The full registry of HTTP status codes is maintained by the IANA.
What Is a 301 Redirect?
A 301 redirect is an HTTP status code that permanently redirects one URL to another. When a user or search engine tries to visit the original page, the server automatically sends them to the new destination, and tells search engines that this move is permanent.
This is essential in SEO when you want to preserve the authority, rankings, and link equity of an existing page while moving to a new URL. Whether you’re rebranding, cleaning up your URL structure, or consolidating content, a 301 redirect is your go-to method.
Why 301 Redirects Matter in SEO
When used correctly, 301 redirects help you:
- Preserve SEO value: A 301 tells Google to pass the original page’s link equity to the new URL
- Avoid broken links: Prevent users from landing on 404 pages
- Consolidate duplicate content: Merge multiple URLs into a single destination
- Maintain rankings after migrations: Essential during website migrations
At BrisTechTonic, we’ve seen websites lose 40–60% of their organic traffic overnight because they failed to redirect old URLs after a site relaunch. That’s why all our SEO audits and SEO packages include full redirect mapping.
How Does a 301 Redirect Work?
When someone visits a URL that has been redirected, the server sends a 301 Moved Permanently status code to the browser or bot, along with the new location. The browser or search engine then requests the new page instead.
In HTTP headers, it looks like this:
HTTP/1.1 301 Moved Permanently
Location: https://www.example.com/new-page/This tells Google: “Hey, this content has moved, please update your index and rankings accordingly.”
When to Use a 301 Redirect
Here are common use cases:
- You’re updating a URL to be shorter or more keyword-focused
- You’re deleting a page and want to redirect traffic elsewhere
- You’re consolidating several thin or duplicate pages
- You’ve moved from HTTP to HTTPS
- You’re rebranding and changing domains
- You’re fixing canonical issues
All of these require thoughtful redirect planning to avoid losing traffic or breaking user journeys.
How to Implement a 301 Redirect
Depending on your platform, there are different methods:
WordPress (with Rank Math or Redirection plugin)
- Use the Redirection plugin or Rank Math’s built-in redirect manager
- Set the source URL and destination URL
- Select “301 – Permanent Redirect” as the type
Apache (.htaccess)
Redirect 301 /old-page/ https://www.example.com/new-page/NGINX
rewrite ^/old-page/?$ https://www.example.com/new-page/ permanent;Shopify & Wix
- Both have built-in redirect managers, just go to your site’s admin panel and input the old and new URLs
We cover all of these implementations step-by-step in our SEO Blueprint course.
301 Redirect vs 302 Redirect
A 302 redirect is temporary. It tells search engines not to update their indexes or transfer link equity. Use a 302 if you’re doing A/B testing or temporarily removing a page.
Use a 301 redirect when:
- The move is permanent
- You want SEO value transferred
- You want the old URL de-indexed in favour of the new one
Risks of Not Using 301 Redirects
If you delete or move pages without redirecting them, here’s what can go wrong:
- Users hit 404 pages – Poor experience, higher bounce rate
- Lost link equity – Backlinks to the old URL won’t pass value
- Lost rankings – The new URL may not inherit the original’s authority
- Duplicate content – If both URLs are live without canonicalisation
How BrisTechTonic Handles Redirects
We plan redirects proactively, not reactively. During site migrations or new content strategies, we create a redirect mapping spreadsheet, matching old URLs to new destinations, and implement them all before launch.
We also regularly audit client sites to identify:
- Broken or outdated redirects
- Redirect chains (bad for speed and crawl budget)
- Multiple redirects pointing to irrelevant destinations

301 Redirect and Link Equity
Contrary to old myths, Google has confirmed that 301 redirects do pass PageRank (link equity). However, if you’re redirecting to irrelevant content, or chaining multiple redirects together, you will likely lose some value along the way.
Best practice? Redirect old pages to the closest equivalent content, not just the homepage.

Frequently Asked Questions
What is the difference between a 301 and a 302 redirect?
A 301 is permanent: Google updates its index to use the new URL and passes ranking signals across. A 302 is temporary: Google keeps the old URL in its index and treats the redirect as a short-term diversion. Use 301 for any permanent change. Use 302 only when the move is genuinely temporary (e.g. seasonal campaign pages).
How do I implement a 301 redirect?
Three common methods. In .htaccess on Apache servers (Redirect 301 /old-url /new-url). In your CMS via a redirect plugin (Redirection in WordPress is the standard). At the CDN level (Cloudflare, AWS CloudFront). All work; pick whichever matches your stack.
Will a 301 redirect hurt my SEO?
Not when used correctly. Google has stated that 301s pass full ranking signals. The risk is misuse: redirecting unrelated pages to consolidate authority is treated as manipulation. Redirect to relevant successor content and 301s help; redirect to your homepage or unrelated pages and Google may ignore the signal entirely.
Should I 301 redirect HTTP to HTTPS?
Yes, and use force-HTTPS rules at the server level rather than per-page redirects. This is one of the most common 301 use cases on the modern web. Most modern hosts handle it automatically when SSL is enabled, but verify it is in place across all URLs.
Take this further
301 redirects are deceptively simple. The fundamentals are easy; the real-world implementations (chains, loops, near-duplicates) are where most sites quietly leak SEO equity over time.
