How to properly implement a 301 Re-Direct

301 redirect is the most efficient and Search Engine Friendly method for webpage redirection. It's not that hard to implement and it should preserve your search engine rankings for that particular page. If you have to change file names or move pages around, it's the safest option. The code "301" is interpreted as "moved permanently".

IIS Redirect

• In internet services manager, right click on the file or folder you wish to redirect
• Select the radio titled "a redirection to a URL".
• Enter the redirection page
• Check "The exact url entered above" and the "A permanent redirection for this resource"
• Click on 'Apply'

<.cfheader statuscode="301" statustext="Moved permanently">
<.cfheader name="Location" value="http://www.new-url.com">

Redirect Old domain to New domain (htaccess redirect)

Create a .htaccess file with the below code, it will ensure that all your directories and pages of your old domain will get correctly redirected to your new domain.

The .htaccess file needs to be placed in the root directory of your old website (i.e the same directory where your index file is placed)

Options +FollowSymLinks RewriteEngine on RewriteRule (.*) http://www.newdomain.com/$1 [R=301,L]

Please REPLACE www.newdomain.com in the above code with your actual domain name.

In addition to the redirect I would suggest that you contact every backlinking site to modify their backlink to point to your new website.

Note* This .htaccess method of redirection works ONLY on Linux servers having the Apache Mod-Rewrite moduled enabled.

Redirect to www (htaccess redirect)

Create a .htaccess file with the below code, it will ensure that all requests coming in to domain.com will get redirected to www.domain.com

The .htaccess file needs to be placed in the root directory of your old website (i.e the same directory where your index file is placed) Options +FollowSymlinks RewriteEngine on rewritecond %{http_host} ^domain.com [nc] rewriterule ^(.*)$ http://www.domain.com/$1 [r=301,nc]

Please REPLACE domain.com and www.newdomain.com with your actual domain name.

Note* This .htaccess method of redirection works ONLY on Linux servers having the Apache Mod-Rewrite moduled enabled.

How to setup a 301 Redirect

The “301 Permanent Redirect”� is the most efficient and search engine friendly method for redirecting websites. You can use it in several situations, including:

• to redirect an old website to a new address
• to setup several domains pointing to one website
• to enforce only one version of your website (www. or no-www)
• to harmonize a URL structure change

There are several ways to setup a 301 Redirect, below I will cover the most used ones:

PHP Single Page Redirect

In order to redirect a static page to a new address simply enter the code below inside the index.php file.

<?php
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.newdomain.com/page.html");
exit();
?>

PHP Canonical Redirect

The Canonical 301 Redirect will add (or remove) the www. prefixes to all the pages inside your domain. The code below redirects the visitors of the http://domain.com version to http://www.domain.com.

<?php
if (substr($_SERVER['HTTP_HOST'],0,3) != 'www') {
header('HTTP/1.1 301 Moved Permanently');
header('Location: http://www.'.$_SERVER['HTTP_HOST']
.$_SERVER['REQUEST_URI']);
}
?>

Apache .htaccess Singe Page Redirect

In order to use this method you will need to create a file named .htaccess (not supported by Windows-based hosting) and place it on the root directory of your website, then just add the code below to the file.

Redirect 301 /old/oldpage.htm /new/http://www.domain.com/newpage.htm

Apache .htaccess Canonical Redirect

Follow the same steps as before but insert the code below instead (it will redirect all the visitors accessing http://domain.com to http://www.domain.com)

Options +FollowSymlinks
RewriteEngine on
rewritecond %{http_host} ^domain.com [nc]
rewriterule ^(.*)$ http://www.domain.com/$1 [r=301,nc]

ASP Single Page Redirect

This redirect method is used with the Active Server Pages platform.

<%
Response.Status="301 Moved Permanently"
Response.AddHeader='Location','http://www.new-url.com/'
%>

ASP Canonical Redirect

The Canonical Redirect with ASP must be located in a script that is executed in every page on the server before the page content starts.

<%
If InStr(Request.ServerVariables("SERVER_NAME"),"www") = 0 Then
Response.Status="301 Moved Permanently"
Response.AddHeader "Location","http://www."
& Request.ServerVariables("HTTP_HOST")
& Request.ServerVariables("SCRIPT_NAME")
End if
%>
