6. You can make money without doing evil

Google is a business. The → revenue we generate is derived from offering search technology to companies and from the sale of advertising displayed on our site and on other sites across the web. Hundreds of thousands of advertisers worldwide use AdWords to promote their products; hundreds of thousands of publishers take advantage of our AdSense program to deliver ads relevant to their site content. To ensure that we're ultimately serving all our users (whether they are advertisers or not), we have a set of guiding principles for our advertising programs and practices:

• We don't allow ads to be displayed on our results pages unless they are relevant where they are shown. And we firmly believe that ads can provide useful information if, and only if, they are relevant to what you wish to find – so it's possible that certain searches won't lead to any ads at all.

• We believe that advertising can be effective without being flashy. We don't accept pop-up advertising, which interferes with your ability to see the content you've requested. We've found that text ads that are relevant to the person reading them draw much higher clickthrough rates than ads appearing randomly. Any advertiser, whether small or large, can take advantage of this highly targeted medium.

• Advertising on Google is always clearly identified as a "Sponsored Link," so it does not compromise the integrity of our search results. We never manipulate rankings to put our partners higher in our search results and no one can buy better PageRank. Our users trust our objectivity and no short-term gain could ever justify breaching that trust.

7. There's always more information out there

Once we'd indexed more of the HTML pages on the Internet than any other search service, our engineers turned their attention to information that was not as readily accessible. Sometimes it was just a matter of integrating new databases into search, such as adding a phone number and address lookup and a business directory. Other efforts required a bit more → creativity, like adding the ability to search news archives, patents, academic journals, billions of images and millions of books. And our researchers continue looking into ways to bring all the world's information to people seeking answers.

8. The need for information crosses all borders

Our company was founded in California, but our mission is to facilitate access to information for the entire world, and in every language. To that end, we have offices in dozens of countries, maintain more than 150 Internet domains, and serve more than half of our results to people living outside the United States. We offer Google's search interface in more than 110 languages, offer people the ability to restrict results to content written in their own language, and aim to provide the rest of our applications and products in as many languages as possible. Using our translation tools, people can discover content written on the other side of the world in languages they don't speak. With these tools and the help of volunteer translators, we have been able to greatly improve both the variety and quality of services we can offer in even the most far-flung corners of the globe.

9. You can be serious without a suit

Our founders built Google around the idea that work should be challenging, and the challenge should be fun. We believe that great, creative things are more likely to happen with the → right company culture – and that doesn't just mean lava lamps and rubber balls. There is an emphasis on → team achievements and pride in individual accomplishments that contribute to our overall success. We put great stock in our employees – energetic, → passionate people from diverse backgrounds with → creative approaches to → work, play, and life. Our atmosphere may be casual, but as new ideas emerge in a café line, at a team meeting or at the gym, they are traded, tested and put into practice with dizzying speed – and they may be the launch pad for a new project destined for worldwide use.

10. Great just isn't good enough

We see being great at something as a starting point, not an endpoint. We set ourselves → goals we know we can't reach yet, because we know that by → stretching to meet them we can get further than we expected. Through → innovation and → iteration, we aim to take things that work well and improve upon them in unexpected ways. For example, when one of our engineers saw that search worked well for properly spelled words, he wondered about how it handled typos. That led him to create an intuitive and more helpful spell checker.
