To redirect old links to new ones, you can use several methods depending on the type of website you have and the server it is hosted on. The most commonly used methods for redirecting URLs include using HTTP status codes (like 301 or 302), writing redirect rules in an .htaccess file (for Apache servers), or configuring redirections through server or website management tools. Let’s go through these methods in detail.
- Methods to Redirect Old Links to New Ones
- 1. Using HTTP Status Codes
HTTP status codes are a standard way to communicate the status of a client’s request from the server. Two of the most common status codes used for redirection are:
- 301 Moved Permanently: This code indicates that the old URL has been permanently moved to the new URL. Search engines like Google will update their index to reflect the new URL.
- 302 Found/Temporary Redirect: This code indicates that the URL has been temporarily moved. It will not prompt search engines to update their index.
- Example:
```

- 2. .htaccess Redirects (Apache)
The .htaccess file is a configuration file used by Apache web servers to manage URL redirections, among other tasks.
- Example:
```
- Permanent URL redirection
Redirect 301 /oldpage.html http://www.newsite.com/newpage.html
- Temporary URL redirection
Redirect 302 /oldpage.html http://www.newsite.com/newpage.html
```
Additional examples include redirecting an entire directory or a domain:
```
- Redirect an entire directory
Redirect 301 /old-directory http://www.newsite.com/new-directory
- Redirect an entire domain
Redirect 301 / http://www.newsite.com/
```
- 3. Server-Side Scripting (PHP)
You can also use server-side scripting languages like PHP to handle redirections.
- Example:
```
header(“Location: http://www.newsite.com/newpage.html”, true, 301);
exit();
?>
```
- 4. Content Management Systems (CMS)
If you are using a CMS like WordPress, there are plugins available to manage URL redirects easily.
- Example Plugins:
- Redirection: This plugin allows you to manage 301 redirections directly from the WordPress dashboard.
- Simple 301 Redirects: Useful for less complex redirection needs.
