Nibbler is a free online SEO checker to test your website for SEO, accessibility on different platforms, website ranking, website pages optimization for printability, popularity, analytics, internal links, and much more. It tests 5 pages (as sample) of a website and performs more than 20 tests. For each test, it generates a score out of 10, which gives a good idea about how good your website is.

Apart from testing and providing the score for your website, it also helps to find out problems related to your website. It also provides suggestions to solve those problems. For example, if your website is not linked with Twitter, Google+, and Facebook, then it will suggest you to sign up to these social networks, and link your website with your social accounts. A detailed report for your website is presented to you.

I found results generated by this website as satisfactory and accurate. In spite of the fact that it tests only 5 pages, this website is handy to test problems, and find solutions for improving your website.
