You can do a redirect with the html meta tag, but we would advise you not to due to it's misuse, most search engines will de-index a page with this usage.  Use one of the solutions noted below.

301 Redirect Using htaccess (for linux hosting customers only)

Using htaccess to accomplish the 301 redirect is highly suggested due to it being fairly convenient to manage, rather than setting redirects on each individual page, you can simply add the redirect code to the .htaccess file.

Here is how to do it:

  1. Create a file on the root directory of your website, name it ".htaccess".
  2. Open the .htaccess file using notepad or what ever text editor that you prefer.
  3. Add this into the .htaccess file, save it and then upload it to your web server:

Redirect 301 /old/old.html

NOTE: Don't add "http://www" to the first part of the statement - place the path from the top level of your site to the page. Also ensure that you leave a single space between these elements:

redirect 301 (the instruction that the page has moved)
/old/old.html (the original folder path and file name) (new path and file name)

301 Redirect Using Mod_Rewrite (for linux hosting customers only)

Mod_Rewrite has got to be one of the most useful modules a server can have in terms of SEO, it allows you to organize the file structure of your web site in a dynamic yet simple fashion. In this example I show a useful method of 301 redirecting with mod_rewrite.

When somebody links to your website, sometimes they dont always link to you in the way that you want them to. If somebody links to and somebody else links to, Google will assign a separate pagerank for each of those. By inserting the below example into your .htaccess file, it will solve the problem by redirecting anything linking to to, also redirecting the pagerank.

RewriteEngine On
rewritecond %{http_host} ^

rewriteRule ^(.*)$1 [R=301,L]

If you want, instead, to remove www from a URL, you can use the code below.

RewriteEngine On
RewriteCond %{HTTP_HOST} ^$ [NC]
RewriteRule ^(.*)$$1 [R=301,L]


301 Redirect on a DNN site where you want to redirect traffic from a prior page which no longer exists

(provided by customer Tom)

Set the old page up in the dnn portal. Do Not include it on the menu. In the page management, in the Link section you can link to the new page and select the check box that says Permanent Redirect (this is the DNN version of 301).
