Google Ads, formerly known as Google AdWords, is a platform for creating and displaying online advertising campaigns. It allows businesses to create ads that appear in Google search results and on other websites that partner with Google to show ads. Advertisers can choose from various ad formats, including text, image, and video ads, and can target their ads to specific audiences based on factors such as keywords, location, and interests. The platform uses a pay-per-click pricing model, in which advertisers are charged each time someone clicks on one of their ads.
