Google Ads is an online advertising platform by Google that allows businesses to display ads on Google's search engine results pages, YouTube, and across its network of partner sites and apps. It operates on a pay-per-click (PPC) model, meaning advertisers only pay when a user clicks on their ad. With Google Ads, you can target specific audiences, locations, keywords, and even set a budget that fits your goals, making it highly customizable for different types of campaigns.
