Redirects are an essential part of website development and management. They allow website owners to direct users and search engines to the correct page, even if the URL has changed. In this ultimate guide, we will explain the different types of redirects, their purpose, and how to use them correctly. We will also discuss the impact of redirects on SEO and how to avoid common redirect issues.
What are URL Redirection?
URL redirections, also known as URL forwarding or URL redirection, is the process of directing a user or a search engine from one URL to another. This can be done for a variety of reasons, such as when a website’s structure is redesigned, when a page is renamed, or when a website is consolidated.
There are several types of URL redirections, including:
- 301 redirect: A permanent redirect that tells both users and search engines that a specific URL has been permanently moved to a new location. Search engines will update their index accordingly and the new page will inherit the link equity of the previous page.
- 302 redirect: A temporary redirect that tells both users and search engines that a specific URL has been temporarily moved to a new location. Search engines will not update their index, and the new page will not inherit any link equity from the previous page.
- 307 redirect: A temporary redirect that is similar to a 302 redirect but it is used for HTTP/1.1 only.
- 308 redirect: A permanent redirect that is similar to a 301 redirect but it is used for HTTP/1.1 only.
URL redirections are important for maintaining the integrity of a website and ensuring that users and search engines are directed to the correct page. They are also important for SEO, as they can help to preserve link equity and prevent duplicate content issues.
There are two types broadly, permanent and temporary. You won’t be able to distinguish between the two. However, they are crucial for search engines. And that’s because, when you don’t want for the old page to be displayed once more, use permanent redirects. similar to deleting a page. or if duplicate pages are combined. They instruct search engines to stop displaying the previous URL in search results and to begin showing the new one instead. Then there are brief redirects. They are used when you only need to temporarily redirect a page. Lets learn about them in detail.
Permanent redirects, also known as “301 Moved Permanently,” use the HTTP status code 301 to indicate that a specific URL has been permanently moved to a new location. When a user or a search engine requests a page that has been permanently moved, the web server returns a “301 Moved Permanently” HTTP status code, along with the new URL. The user’s browser or the search engine will then automatically request the new URL, ensuring that the user is directed to the correct page.
Permanent redirects are typically used when the URL of a page has been changed permanently, such as when a website’s structure is redesigned or when a page is renamed. It is also used when merging two websites and redirecting users from the old website to the new one. One of the most important considerations for permanent redirects is SEO. Search engines use redirects to update their index and ensure that users are directed to the correct page.
A permanent redirect is used correctly, it will not negatively impact your SEO. The link equity of the previous page will be passed on to the new page, meaning that the new page will retain the same value and ranking in search engine results.
Temporary redirects, also known as “302 Found” or “302 Moved Temporarily,” use the HTTP status code 302 to indicate that a specific URL has been temporarily moved to a new location. When a user or a search engine requests a page that has been temporarily moved, the web server returns a “302 Found” or “302 Moved Temporarily” HTTP status code, along with the new URL. The user’s browser or the search engine will then automatically request the new URL, ensuring that the user is directed to the correct page.
Temporary redirects are typically used when a page is temporarily unavailable, such as during maintenance or when testing a new page. It is also useful when you want to redirect users to a new page but the original page will be back after a certain period of time. Unlike permanent redirects, search engines will not update their index when a temporary redirect is used, and the original page will still be indexed, and the new page will not inherit any link equity from the original page.
Now comes HTTP Redirects that we have briefly introduced in the beginning and now we are learn about them in detail and learn where to use them.
301: Moved permanently
A 301 redirect, also known as “Moved Permanently,” is an HTTP status code that indicates that a specific URL has been permanently moved to a new location. When a user or a search engine requests a page that has been permanently moved, the web server returns a “301 Moved Permanently” HTTP status code, along with the new URL. The user’s browser or the search engine will then automatically request the new URL, ensuring that the user is directed to the correct page.
The primary use case for 301 redirects is when the URL of a page has been changed permanently, such as when a website’s structure is redesigned or when a page is renamed.

302: Redirected temporarily
A 302 redirect, also known as “Found” or “Moved Temporarily,” is an HTTP status code that indicates that a specific URL has been temporarily moved to a new location. When a user or a search engine requests a page that has been temporarily moved, the web server returns a “302 Found” or “302 Moved Temporarily” HTTP status code, along with the new URL. The user’s browser or the search engine will then automatically request the new URL, ensuring that the user is directed to the correct page.

Unlike 301 redirects, search engines will not update their index when a 302 redirect is used, and the original page will still be indexed, and the new page will not inherit any link equity from the original page.
303: See Other
A 303 redirect, also known as “See Other,” is an HTTP status code that indicates that the requested resource has been replaced by another resource. It is used to redirect the user or search engine to a different URL, but it also indicates that the original resource is still available and can be retrieved by using a GET request. This status code is not widely used and it is similar to a 302 redirect in its function.
307: Temporary Redirect
A 307 redirect, also known as “Temporary Redirect,” is an HTTP status code that is similar to a 302 redirect, but it is used for HTTP/1.1 only. This type of redirect tells both users and search engines that a specific URL has been temporarily moved to a new location. When a user or a search engine requests a page that has been temporarily moved, the web server returns a “307 Temporary Redirect” HTTP status code, along with the new URL. The user’s browser or the search engine will then automatically request the new URL, ensuring that the user is directed to the correct page.
The primary use case for 307 redirects is to indicate that the page has been temporarily moved to a new location, but it is only processed by HTTP/1.1 compliant user-agents. It is not widely used, and most web browsers and servers treat a 307 redirect as a 302 redirect.
To implement 307 redirects, you have several options. You can use .htaccess files on Apache servers, IIS web.config files on Microsoft servers, or use server-side scripting languages such as PHP or Python. However, because it is not widely used, it may not be supported by all web servers or Content Management Systems (CMS).
308: Permanent Redirect
A 308 redirect, also known as “Permanent Redirect,” is an HTTP status code that is similar to a 301 redirect, but it is used for HTTP/1.1 only. This type of redirect tells both users and search engines that a specific URL has been permanently moved to a new location. When a user or a search engine requests a page that has been permanently moved, the web server returns a “308 Permanent Redirect” HTTP status code, along with the new URL. The user’s browser or the search engine will then automatically request the new URL, ensuring that the user is directed to the correct page.

Redirects can have a significant impact on SEO, and it is essential to implement them correctly. When a redirect is implemented correctly, it will not negatively impact your SEO. However, if a redirect is implemented incorrectly, it can cause a loss of link equity and negatively impact your SEO.
One of the most important considerations when using redirects is to avoid redirect chains. A redirect chain occurs when a page is redirected to another page, which is then redirected to another page, and so on. This can cause a significant loss of link equity and negatively impact your SEO. To avoid redirect chains, it is essential to redirect users and search engines directly to the final destination page.
What is HTTP/1.1?
HTTP/1.1 is the latest version of the HTTP (Hypertext Transfer Protocol) protocol, which is used to transfer data over the internet. It is an application protocol that is used to transfer data between a web server and a web client (such as a web browser). HTTP/1.1 is an improvement over the previous version of the protocol, HTTP/1.0, and it was first standardized in 1999 by the Internet Engineering Task Force (IETF).
HTTP/1.1 is widely supported by web servers and web browsers, and it is the default protocol used by most web-based applications. It is also the foundation for other protocols such as HTTPS and HTTP/2.
What are the features of HTTP/1.1?
HTTP/1.1 introduces several important features that improve the performance and functionality of the protocol. Some of the key features of HTTP/1.1 include:
- Persistent connections: HTTP/1.1 allows a single TCP connection to be reused for multiple requests, which improves the performance of the protocol by reducing the overhead of creating and closing connections.
- Chunked transfer encoding: This feature allows a server to send large files to a client in smaller chunks, which improves the performance of the protocol when transferring large files.
- Conditional requests: This feature allows a client to send a request to a server, and the server only sends the requested resource if it has changed since the last time the client requested it.
- Host header field: This feature allows a single IP address to host multiple web sites by specifying the hostname of the requested site in the HTTP request header.
- Improved caching: HTTP/1.1 includes several caching headers that allow the client and server to better control the caching of resources.
What is Canonicalization?
Canonicalization is the process of choosing the best URL when there are multiple URLs available for the same content. This is important for SEO, as it helps search engines to understand which version of a page should be indexed and shown in search results. It also helps to prevent duplicate content issues, which can negatively impact a website’s SEO.
There are several ways to implement canonicalization, including:
Using the rel=”canonical” link element: This is the most common method of implementing canonicalization. The rel=”canonical” link element is placed in the head of a page and points to the preferred version of the page. Search engines will use this information to determine which version of the page to index.
