“301” Redirects for SEO

Search engines will often regard www.example.com and example.com as two different websites. Because of this, websites usually experience the effects of link fragmentation (inbound links point to both www.example.com and others to example.com). For example, if www.example.com has 5,000 inbound links and example.com has 2,500 inbound links you could potentially combine them so you have all 7,500 links pointing to www.example.com.

To do this you can setup a permanent “301” redirect by creating a .htaccess file with the below code. This will ensure that all requests coming in to example.com will get redirected to www.example.com.

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

Notes:

  • 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)
  • REPLACE example.com and www.example.com with your actual domain name in the code above
  • This .htaccess redirection method only works on servers using the Apache Mod-Rewrite module

This “301” redirect method is also a great way to save money on SSL certificates. When the site always points to www.example.com you only need to buy a single SSL certificate.

Using PHP on Pages with HTML Extensions

Recently I wanted to use PHP includes in an existing site so I could make updates to common parts of the site faster by editing one file (e.g.: header, navigation, footer, etc.). The problem was the site was designed with all pages ending in .html. Of coarse I could have changed all the pages to .php but the site has very good search engine rankings, and many other sites already link to these .html pages. After a little research, I found the solution to be the .htaccess file.

Since pages without a .php-extension will not be parsed by PHP by default on most web servers, you need to tell it to treat all HTML pages as PHP pages. You do this by simply adding a line to the .htaccess file located in your site’s root directory (or create a .htaccess file using a text editor). Just add:

AddType application/x-httpd-php .php .html .htm

Note: .htaccess files need to be placed in each directory that will make use of PHP in .html pages.

Update: If you get an 500 Internal Server Error try:

AddHandler application/x-httpd-php .php .html .htm
