I would like to create a part of my website that can grade / rate a website based on their overall on-page / off-page optimization. The site should be similar to: http://marketing.grader.com It does not have to be as robust as this site, but should work similarly in offering advice / tips on how to improve the site optimization for whichever site was submitted. I especially like how it will pull information from blogs, twitter and facebook to see the overall strength of the social media...
