Paid search advertising, also called pay-per-click (PPC) advertising, allows businesses to display ads on search engines like Google and Bing. When users search for keywords related to a product or service, the business's ad appears on the search results page. The business only pays if the ad is clicked. To start a paid search campaign, businesses set up accounts on Google AdWords or BingAds, choose keywords and ads, set a budget and monitor results. Both small and large businesses use paid search marketing to reach customers searching online and increase sales and brand awareness.
