1. GoogleplexThe Googleplex is the company headquarters in Mountain View, California. The name is a play on both "Google complex" and "googolplex," the number you get when you take a one and add a googol zeroes to it.
The Googleplex provides employees with unusual perks, like hair cuts, laundry facilities, and gourmet meals. While Google has been scaling back on some of their perks during economic hardship, employees still enjoy some fantastic benefits.
2. GooglersGooglers are employees of Google. There are also several variations of the term, like "Gayglers" for gay and lesbian employees, Bikeglers for employees who bike to work together, and Newglers for new employees. Former employees sometimes even refer to themselves as Xooglers.
3. 20-Percent TimeGoogle engineers are allowed to spend twenty percent of their work time on pet projects. The philosophy is that this outlet helps Googlers stay creative and energized.
Sometimes these "20-percent projects" are dead ends, but often they end up being developed into full-fledged Google offerings. Some examples of projects that benefited from twenty percent time include Orkut, AdSense, and Google Spreadsheets
4. Don't Be Evil"Don't be evil" is an unofficial Google motto. Google's corporate policy page phrases it "You can make money without doing evil."
This is an awfully high standard, and a lightening rod for Google criticisms. Concerns over privacy, market dominance, or Chinese censorship inevitably have critics asking if Google is "being evil."
5. PageRankPageRank is the algorithm that made Google what it is. PageRank was developed by Google founders Larry Page and Sergey Brin at Stanford. Rather than just calculating keyword density, PageRank factors in how others link to a particular page.
Although PageRank is not the only factor in determining how well a website will rank in Google results, it's certainly important to understand how PageRank works if you are website creator.
6. Eating Your Own Dog FoodThis wasn't a phrase that originated at Google, but it's certainly been heard there. The phrase comes from the idea that if your product is terrific, it ought to be a product you use yourself.
Google does this with most of their products by using them internally as much as possible. It's easier to catch bugs and fix inconveniences if it's a product you use yourself.
Google is certainly not the only technology company to eat their own dog food. It's a phrase used at Microsoft, too.
Google's business model relies on The Long Tail. Google allows small advertisers to place inexpensive, highly specialized ads in places targeted to a receptive audience.
