digital marketing Bd- Paid search, or pay-per-click (PPC) advertising, typically refers to the “ sponsored result ” on the top or side of a search engine results page (SERP). You only pay when your ad is clicked. 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, effective 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.
