The tool is called Website Grader (http://website.grader.com).
All you need to do is enter your site address, email address, and, optionally, the address(es) of your competitor(s).
The site takes between a couple seconds-minutes to calculate your rank, then sends the report to you in an email.
Above is a screenshot of a sample report (click here for the full sample).
The report consists of things such as:
- The number of images on your site
- Your site's 'readability level'
- Domain age, expiration date
- Google PageRank
- Google Indexed Pages
- Last Google Crawl Date
- Inbound Links
- Competitive Info
