Here are a few sites i use, they are not 100% accurate. They all give you an idea of how your site tests out for proper titles, description, keywords and various other things. This first link is the most detailed one i have found.
http://seositecheckup.com/ Insert your url and it will give you a list of the good and bad about your site.
This is a good quick look. Although it always states there is no robots.txt when in fact others state there is and i know there is.
