It is often referred as pay-per-click (PPC) advertising, which refers to the “sponsored result” on the top of search engine results page. You will pay when your ad displayed receives a click by the website user. You can tailor your PPC ads to appear when specific search terms are entered, creating ads that are targeted to a particular audience. PPC ads are flexible, visible, and most importantly, useful for many different types of organizations. They are also contextual advertisements—ads that appear when a person is searching for a particular keyword or term.
