How to Enable SEF URLs in Wordpress

1. Log into the Wordpress Dashboard at Wordpress.com.
2. Click 'Settings,' then 'Permalinks.' Under 'Common Settings,' select the 'Custom Structure' radio button; this will allow you to enter your own template for permalinks in the adjacent box.

3. Type:/%post_id%/%postname%.htmlThis creates permalinks of the form 'http://www.yourblog.com/53/title-of-post-fifty-three.html,' with both the post's number and title rendered legibly in the URL. Click 'Save Changes' to incorporate the new style.
