Search engines provide almost all of the online advertising for internet users. Many companies use search engine marketing to reach out to potential customers and promote their products. Customers request information from potential advertisers with search terms. It helps advertisers promote their products with relevant information. Advertisers can pay to appear higher in the results for certain keywords. For example, if an insurance company wanted to advertise auto insurance, it could pay to appear higher when someone searched for ‘auto insurance. Companies even run targeted search terms for customers looking for something specific. As an example, if a restaurant wanted people to find information about where to eat ethnic food in the US, it might run a term like ‘ethnic food recommendations.’ In addition, advertisers can pay for greater placement on search engine results pages (SERPs). This can include the top or side of the page, which are good entry points for potential customers.
