See the scores above? This tells you how well each wordpress post you make scores from an on page SEO perspective.
One of the best ways to use the Measure My SEO Plugin is to put it on a blog that has a lot of posts -- then once it's installed quickly glance and see which ones have high scores and which ones don't.
The ones that don't - well that's obvious - make simple improvements. Go to each post and it will tell you what you need to do from an SEO perspective that you're currently not doing. Just make the change and the score instantly refreshes!
