Advertising

 * In 2011, 96% of Google's revenue was derived from its advertising programs.Google has implemented various innovations in the online advertising market that helped make it one of the biggest brokers in the market. Using technology from the company DoubleClick, Google can determine user interests and target advertisements so they are relevant to their context and the user that is viewing them. 
 * One of the disadvantages and criticisms of this program is Google's inability to combat click fraud, when a person or automated script "clicks" on advertisements without being interested in the product, causing that advertiser to pay money to Google unduly. Industry reports in 2006 claim that approximately 14 to 20 percent of clicks were fraudulent or invalid. 

What is Google

 * Google+ is a multilingual social networking and identity service owned and operated by Google Inc. It is the second-largest social networking site in the world, having surpassed Twitter in January 2013.
 * These include search, cloud computing , software and online advertising technologies. Most of its profits are derived from AdWords . 









Growth

 * In March 1999, the company moved its offices to Palo Alto, California, which is home to several prominent Silicon Valley technology startups. The next year, against Page and Brin's initial opposition toward an advertising-funded search engine, Google began selling advertisements associated with search keywords.
 * In order to maintain an uncluttered page design and increase speed, advertisements were solely text-based. Keywords were sold based on a combination of price bids and click-throughs, with bidding starting at five cents per click.
