While you consider what to do next to optimize your site, or you wait for the next big update, remember to add more content. What else can you add that increases the value of your site? Keep a simple txt file or note pad handy for when an idea strikes you. Jot it down so when you have time later, you can glance through the notes and pick a subject to write about. Add that content to your site as often as possible. Sometimes, bigger is better, and if you continue to increase the value of your site, your rankings will eventually reflect that.
