How to setup a 301 Redirect


background image

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.

header("HTTP/1.1 301 Moved Permanently");

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 version to

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

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/

Apache .htaccess Canonical Redirect

Follow the same steps as before but insert the code below instead (it will redirect all the visitors accessing to

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

ASP Single Page Redirect

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

Response.Status="301 Moved Permanently"

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

    thanx bro.. i search many at google.. but your tips is better..

  • Chris

    Great article!
    But I do have a question about the www or no www
    Where exactly do I add this code? .htaccess file?

  • Ashwini

    I have a question.
    I currently work on blogger domain and will soon shift to a custom domain.301 redirect will be enough to transfer the google juice but does the same goes for Technorati?

  • Jerry Peters

    The ASP Canonical Redirect code above is for redirecting the non-www domain name to the www domain name. What is the code if you are going the opposite direction–redirecting from the www domain name to the non-www domain name?

    Also, I assume the code is placed at the top of every page before the and tags. Is this correct?

    Thanks in advance for your help on this.

  • Outlaw

    Very interesting info. However did anyone have any experience with trailing slashes at the end of subdirectory on your domain. For instance: and
    how are these treated? I saw some of people having problems with that and both pages indexed. any htaccess ideas on that?

  • Tricia

    I’m using a 301 redirect on my main blog to include the www. The problem is that I have a few other blogs on this domain that I put in directories ie I want the directory blogs to have urls that do not contain the www because they have higher PR without the www in their urls, yet the main domain has a higher PR with the www in it’s url.

    So I’ve been using the nowww plugin on my directory blogs to keep the www out of the urls. I suspect this might actually be causing a bit of a problem on a few of the blogs because now they occasionally have the primary domain thewebfiles in their url as well if it’s accessed without a trailing slash. for example the Odd Planet blog sometimes converts it’s urls to

    I’d like to use an htaccess redirect to keep the www out my directory urls so I could avoid using the plugin. I’ve also read that the plugin might be using more cpu resource in my account and I’ve just had a terrible experience with web hosts and cpu resource over use so I want to trim down.

    Do you have any idea what htaccess redirect I might use to solve my problem?

  • Daniel

    TechZilo, maybe it is something related to your host then.

    The easiest option now is just to go to Google Webmaster tools, verify your blog and choose a “Preferred Domain”, that way Google at least will know what version it should use.

  • TechZilo

    I tried the plugin,but it took down the blog.
    i tried the php one, but it didnt work. can you explain in detail?

  • Daniel

    Did you try the PHP one? If the PHP words there is no need to use an .htaccess redirect. Also there is a plugin that does this job, check this post:

  • TechZilo

    I don’t have an htaccess file now, and need to upload one. My FTP client, fireftp, doesnt allow upload of .htaccess file

    I tried uploading a txt and renaming it to .htaccess
    it didnt work either.

    how can i set up htaccess redirect now?

  • Daniel

    Put it in the beginning, but it should not matter.

  • TechZilo

    Yes, Canonical redirect. Where in header? at the beginning, middle or end?

  • Daniel

    Which one, the PHP Canonical redirect?

    This one go on the header.php file on your theme.

  • TechZilo

    I couldn’t understand the second method, ie non-www to www redirect. Where should I place the code? .htaccecss?

  • Ranjana

    Hi Daniel,

    The problem is it does not get resolved to, it stays as

    As a result “” is still in the search results and “” is not getting the required exposure.

    How do I tackle that?



  • Daniel

    Renjana, if is pointing to, people will already get forwarded there, there is no need to setup a 301 in that case.

  • Ranjana


    We have several domains pointing to the same web site.

    For instance –,,

    Our main domain name is –

    All the above mentioned domains and the main domain point to the same server… as in
    there is only one folder for these domains.

    How do I incorporate .htaccess in this case?

    I mean I do not have separate folders for any of these domains but I want that if any one

    types in “”, it should get resolved to “”.

    One of the domains is very old and is registered in search engines. I do not want to lose out on that. Am desperately looking for a solution to this problem.

    I hope I have been able to explain the situation properly.

    What should I do if my virtual host provider do not configure IIS to do redirect for me? My host use html+asp.

    wow, many many thanks. I used the .htaccess way, and it worked like a charm. now i understand why sometimes I see a google page rank of 4 and sometimes 0 on a site of mine. those nasty “wwww” makes huge difference.

  • Affiliate Manager

    For the most part I’ve been trying to make sure all of my sites just have the redirect for www. to the non www. For one, it’s a lot easier and quicker to type in the non “www” and if I’m going to submit my sites to hundreds of directories, it can save a lot of time.

    So, I personally go with non “www.” 🙂

  • Enblogopedia

    Well I think it`s the easiest way,
    check this article. I don’t mess with my file templates..and I think the code is true but I want the “OKAY” from a prof. that`s all. :s

  • Daniel

    Enblogopedia, I am not sure about changing the URL structure with .htaccess. I tried it sometime ago with PHP, but it was a mess.

    I will let you know if I find something online.

  • Enblogopedia

    I want to change my permalinks from

    I believe the code will be something like this:

    RewriteEngine On
    RewriteRule ^([0-9]{4})/([0-9]{2})/([0-9]{2})/(.+) http: //$1

    (of course with out the line break!)
    Am I right?!

  • Bes Z

    Sorry if this is a repost, for some reason I pressed the “Say it!” button and I got refreshed and sent back to this page and couldn’t see my comment [you can delete my earlier comment if it goes through].

    Nice work, Daniel. 🙂 I am going to use it as one of my cheat sheets now.

    For WordPress users who change their permanent links [permalinks] and wish to use 301 redirects to point users, search engines and others to the new urls, Dean Lee created a migration plugin which does just that:

    Of course, it only works on WP pages and not pages created outside of WP.

    Thanks for sharing. 🙂

  • Daniel

    Lionel, that is a good way to solve the problem of redirecting single files without affecting the whole website, thanks for sharing.

  • Lionel Young

    Sometimes you need to create a dummy file if you want to do a permanent/temporary redirect. When I switched over to WordPress, I had to redirect index.html to index.php, but the .htaccess in your root folder will affect subfolders — this means your add-on and subdomains.

    All my add-on domains were redirecting to the root domain, and had to create a dummy index.html in the root folder for the HTTP_HOST condition to trigger.

    #Redirect only for elegantcab, and not add-on domains
    RewriteCond %{HTTP_HOST} ^(www\.)?elegantcab\.com
    RewriteRule ^index.html$ [R=301,L,N]

    So if you’re having problems, try creating a dummy file.
