Duplicate content and php header VS .htaccess 301

301, header, google, ban duplicate content

[niki_man]

Because of a misconfiguration and changes, one of my domains is listing three duplicate URLS for my site.

Examples of the same page:
duplicate 1 : [domain.com...]
duplicate 2 : [domain.com...]
Main page--> duplicate 3 : [domain.com...]

My site is suffering a real HARD Google Penalty now :(.

Would a redirect with the php function Header() function like a 301?

Should I use a php header function to send the duplicate pages to the main page (duplicate 3)?

Hope this is clear, it's 4:30 AM where I am...

As long as you specify the correct server response header in php, the php redirect will be indistinguishable from a server-level redirect. You have to specify the redirect as a 301-Moved Permanently, otherwise you'll get a 302 redirect by default. There are several examples of the correct coding over in our PHP forum.

Thanks I am considering this example:

<?php
// Permanent redirection
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://www.example.com/");
exit();
?>

Since this is very important, it worth asking if anyone disagrees with this example...?

ASP 301 technique is also mentioned
