For example, you want to put a backlink to ProxB.Com in your footer.
=> Open your favorite editor
=> Create a new .php file called footer.php
=> Add this in the footer.php file:
=> Open your index.php (or main.php when you're in Glype) file.
<a href="http://proxb.com">Proxy Sites</a>
=> Go to the place where the backlink to ProxB.Com should be visible (the footer)
=> Add this on the place where the backlink should be visible:
The account-username, should be the name you use to login to your FTP.
<? include("/home/account-username/public_html/footer.php"); ?>
=> Login to your FTP. Go to 'public_html'.
=> Upload footer.php into that map.
=> Replace the current index.php (or main.php) with the new file you made in the first step of this little tutorial
Now you should go and check your website's footer. Normally the backlink to ProxB should be visible.
Please tell me if it worked or not
