Key takeaways:
- A 301 redirect permanently sends visitors and search engines from an old URL to a new one.
- Relevant 301 redirects can preserve SEO signals and help search and AI systems find the current page.
- Test every redirect, update internal links, and avoid chains, loops, and unrelated destinations.
Updating an outdated web page may seem as simple as publishing a new page, removing the old one, and moving on. But visitors, bookmarked links, and search engines may still try to reach the old address. Without the right setup, website visitors could land on an error page instead of your updated content, preventing the old address from directing traffic to the correct page.
A 301 redirect is one of several types of URL redirects that can send visitors and search engines from an old address to its permanent replacement. When used correctly, it helps protect traffic and preserve valuable search signals. In this guide, you’ll learn how a 301 redirect works, when to use one, how it affects SEO and AI visibility, and how to do a 301 redirect on your website.
What is a 301 redirect, and how does it work?
A 301 redirect is an HTTP status code that tells browsers and search engines that a web page has moved permanently from one address to another. The “301” appears in the web server’s response rather than on the page itself. To a visitor, it usually looks like an automatic move:
example.com/old-page → example.com/new-pageThe visitor types or clicks the old URL, but the browser opens the new URL without requiring another action. Website owners commonly use 301 redirects when they rename a page, change a site’s URL structure, combine similar content, or move a website to a different domain.
It works when someone requests the old URL by clicking a link, entering the address, or choosing a saved bookmark. The web server checks its redirect rules, and the server responds with a 301 status code and a location header containing the new address. The browser then requests the destination URL and displays the new page.
Search engine crawlers follow a similar path. A permanent redirect signals that the new URL should generally replace the old address in search results.
Think of a 301 redirect as a permanent change-of-address notice. It sends visitors and search engines from the old URL to the new one, while keeping old bookmarks and links useful. The new page should closely match the original page’s purpose.
301 vs. 302 redirect
Both redirects send visitors to another URL, but they serve different purposes. A 301 is for permanent redirects, while a 302 is for a temporary redirect.
Category | 301 redirect | 302 redirect |
|---|---|---|
Purpose | The page has moved permanently | The page has moved temporarily |
Original URL | Search engines may replace it with the new URL | Search engines generally keep it as the main URL |
Browser caching | More likely to be cached as a permanent change | Usually not treated as a permanent change |
Best used for | Domain moves, renamed pages, and content consolidation | Maintenance pages, testing, and short-term promotions |
Use a 301 when the original URL will not return. Choose a 302 when you plan to restore it.
How do 301 redirects affect SEO and AI visibility?
A properly configured 301 redirect can help protect search performance when a page moves permanently. It tells search engine bots that the old URL has a new permanent location. Google crawlers then follow the redirect, process the destination page, and generally consolidate ranking signals associated with the old URL over time.
However, a 301 does not guarantee unchanged SEO rankings. Problems can arise when a redirect points to an unrelated page, creates a redirect chain or loop, leads to an error, or sends many unrelated URLs to the homepage. Redirect each old page to the closest relevant destination, update your internal links, and keep permanent redirects active long enough for search engines to process the change.
301 redirects also affect AI visibility indirectly. Google’s generative AI features use its core search ranking and quality systems, and pages generally need to be crawlable, indexed, and eligible to appear in search results. A clean redirect helps these systems find the current version of your content rather than an outdated or missing URL.
It does not provide a separate boost to AI visibility, but it keeps your content location and technical signals clear. Poor redirects may make it harder for the correct page to be crawled, indexed, or selected as a supporting source.
When to use a 301 redirect
Use a 301 redirect when a page or website has moved permanently, and visitors should always be sent to a new location. Common situations include:
- Deleting a page: Send visitors from a removed page to the most relevant active page instead of leaving them with a broken link
- Changing your site’s URL structure: Redirect each old URL after renaming folders, categories, or page paths
- Moving to a new domain: Redirect the entire domain so visitors and search engines reach the corresponding pages on the new domain
- Switching website platforms: Set up redirects when page URLs change upon moving to a new content management system or website builder
- Combining similar content: Consolidate pages that cover the same topic, then redirect the less useful URLs to the strongest version
When redirecting multiple pages, match each old page to a closely related destination. Avoid sending every URL to the homepage because that can confuse visitors and search engines.
When not to use a 301 redirect
A 301 tells search engines that a move is permanent, so it is not the right choice in every situation. Avoid using one when:
- The move is temporary: Use a 302 temporary redirect when the original URL will return, such as during maintenance or a short-term promotion
- You are running an A/B test: A temporary redirect helps search engines keep the original URL indexed while the test runs
- The page has no suitable replacement: Let a dead page return a 404 or 410 status rather than sending visitors to an unrelated page
- The destination does not match the original content: Redirecting to an irrelevant page can confuse visitors and weaken search signals
Choose the redirect type based on whether the change is permanent or temporary.
How to set up a 301 redirect
The setup process varies by website platform, hosting provider, and web server. For a WordPress site, a redirect plugin such as Yoast is usually the simplest option.
- Install a redirect plugin: In the WordPress dashboard, go to Plugins, select Add new, and search for a free WordPress plugin such as Redirection. Install and activate it. The plugin lets you manage 301 redirects without editing server files directly.
- Identify the two URLs: Copy the path of the old page and the target URL for its new location. For example:
example.com/old-service → example.com/new-service - When moving from an old domain, match each old page with the corresponding page on the new domain rather than sending everything to the homepage.
- Create the redirect: Open the plugin’s redirect manager. Enter the old address in the source field, add the new address in the destination field, and select 301 as the redirect type. Save the rule.
- Test the result: Open the old URL in a private browser window. Confirm that it loads the correct destination and does not stop on an error page or pass through several redirects.
- Update your website links: Change internal links so they point directly to the new URL. The redirect will still serve visitors using old bookmarks or external links, but your own pages should link straight to the current address.
Other platforms may include redirect settings in their dashboards or hosting control panels. On an Apache server, redirects can also be added to the .htaccess file in the site’s root folder. WordPress uses this file to control how Apache serves URLs, so create a backup and ask your hosting provider or a web developer for help before editing it.
Some platforms also support JavaScript redirects or meta refresh redirects, but a server-side 301 is usually the clearer option for permanent moves. A meta refresh moves visitors through the page itself rather than through an HTTP status response.
Common mistakes to avoid when setting up 301 redirects
Small setup errors can create broken links, slow page loads, or send visitors to the wrong content. Watch for these common mistakes:
- Using the wrong redirect code: Choose a 301 only for permanent moves. Use a 302 when the change is temporary.
- Redirecting a newly created page: A new page does not need a 301 unless it replaces an existing URL.
- Forgetting to update internal links: Change links on your website so they point directly to the final URL instead of relying on the redirect.
- Choosing an unrelated destination: Redirect an old URL to a relevant page that meets the same visitor need, not automatically to the homepage.
- Using 302s between domain versions: Use permanent redirects so all versions of your site (HTTP, HTTPS, www, and non-www) resolve to one preferred version.
- Creating redirect chains or loops: Avoid sending a visitor through multiple redirects by pointing each old address directly to the final destination URL.
Frequently asked questions
No. A properly configured 301 redirect helps search engines and visitors reach a page’s permanent new location. Problems usually come from unrelated destinations, broken redirects, loops, or long redirect chains.
Enter the old URL in a private browser window and confirm that it opens the correct page. You can also use an HTTP status checker to verify the 301 response and Google Search Console URL Inspection Tool to review how Google accesses the URL.
Yes. Google states that ranking signals, including signals from incoming links, pass appropriately through 301 redirects. However, search rankings can still change while Google processes the move.
It indicates that a page has moved permanently and that visitors and search engines should use the new URL.
A 301 is for a permanent move. A 302 is for a temporary move when the original page is expected to return.
Keep every URL move on the right path
Use 301 redirects only for permanent changes, and always send each old URL to the most relevant page. Update internal links, test every redirect, and avoid chains or loops that can slow visitors and search engines.
Redirects also support larger changes, such as moving an entire domain. With Network Solutions domain forwarding services, you can direct visitors from one domain name to another destination while keeping the path clear. When redirecting gets complicated, our MyTime Tech Support team can help you configure and check your redirects so visitors reach the right pages.
