Letting you figure out the true usability of your site is the basic premise as far as Set Rating is concerned. On the site, you will be able to procure a widget that once installed will let you poll those who visit your own site or blog, and know what they really think about it.
This widget can be procured (and used) for free, and some of the aspects that it will let you evaluate include the overall design of your site and its accessibility, along with the level of expertise that is needed to fully maximize it.
And not only can this widget be procured at no cost, it can actually be implemented in a hassle-free way. All that you are requested to do is to take the HTML code that is provided and paste it in your site (or blog) for the widget to become visible from that point onwards.
A practical way to start learning in which ways your site can be improved if I ever saw one.
