Most people believe that a Google search is free. After all, you can access the Google search engine without paying any money. However, there are actually many ways in which Google makes money from its search business. One of the most important is through advertising. When you perform a search on Google, you will see a number of ads along with the organic results. These ads are served by Google's AdWords program, and businesses have to pay for them in order to have their ads shown. In addition, Google also sells premium search services, such as the ability to filter out certain types of results or to get detailed information about a particular topic. As a result, while a basic Google search may be free, there are definitely ways in which the company generates revenue from its search business.
