I have been building search engines for a couple of years now. The reason I started doing this is because I figured that if I want to be better at SEO, I should understand exactly how search engines work, what kind of challenges search engine engineers have to deal with on a day-to-day basis, how to keep up with the changing world of the Internet etc.
