Unfortunately if you just point the basic algorithm at a crawl (which you can download for free here ) you’re going to get useless results. In fact, it was an assignment question in my 3rd year numerical methods class. You can actually read Page & Brin’s original paper online and implement it yourself.

Their solution was anything but, and it was truly innovative (at the time) and their success was well deserved.
