Usually I use link function in admin panel to make a link. But since I found this Wordpress shortcode – WP Hack, I think this will save my time a lot. This shortcodes allow me to call a php function simply by typing short code like [ bst ].

To make shortcode function, first you have to make functions.php in your wp-theme folder. Or if you already have it just append this code :

function busby() {
return '<a href="http://www.imfreakz.com/busby-seo-test/">Busby SEO Test</a>';
}
add_shortcode('bst', 'busby');

After append the code in your functions.php => save it and you’re now able to use the [ bst ] shortcode. To use it, write this code [ bst ] (without space) on the editor (in HTML mode) while writing a post.
