Serving duplicate content can downgrade your SEO performance. You can use these 2 simple tricks to fix your URLs for good and give your SEO a nice boost.

Trick #1: Make sure all of your pages have a Canonical URL Tag

The Canonical link tag tells search engines the single URL to use for all versions of a given web page. There are many instances where this is relevant

  • When creating links with Google Analytics or when using other analytic packages you often make links with many variables in them. You will be creating back links to a page that are not unique and could result in a duplicated content penalty.
  • If you have a multi-part article you will want the "SEO Juice" to go to page one so you would make the Canonical link for the series always point to the first page
  • Your page takes dynamic arguments that only affect cosmetic aspects of the page, but will result in many unique urls, thus lowering their SEO value

		header("HTTP/1.1 301 Moved Permanently");
		header("Location: {$protocol}{$mydomain}{$_SERVER['REQUEST_URI']}");

Solution #2: .htaccess file

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