Darin Carter came across a tool that will actually give your website or blog a grade. Not only does this site Grade your Website, it tells you whats wrong with it from a SEO Standpoint.
Website Grader is a free SEO tool that provides an SEO score for your website with custom search engine optimization and marketing advice for your website. Use the form above to enter your website, your keyword phrases and your competitors to receive a report about the marketing effectiveness of your website.
Subscription to the site is totally free and it even gives you a chance to put your site up against other sites in your industry!
You can generate a report for your blog just by entering your URL and nothing else. However, you won’t be allowed to compare your blog to others unless your subscribe. I entered my blog into Website grader and got a grade of 99/100.
A website grade of 99 for www.johnchow.com means that of the thousands of websites that have previously been submitted to the tool, our algorithm has calculated that this site scores higher than 99% of them in terms of its marketing effectiveness. The algorithm uses a proprietary blend of over a dozen different variables, including search engine data, website structure, approximate traffic, site performance, and others.
Only 99%? I thought I was better than that! 
What is your website grade?
