Just came across an interesting interactive explanation of how Google’s search engine works.
Although there are many of us who have been around on the internet long enough to grasp the basic concepts already, I love the interactive elements and visual help guides, something I can send to people who don’t have that understanding.

For a full run down, Google has an entire area dedicated to showing you the ins and outs of how it works in a section called “Inside Search“.
