Google Ads

Google Ads is Google's online advertising platform (formerly known as Google AdWords) that allows businesses to create and display ads to reach people actively searching for related products or services — or browsing across Google properties like Search, YouTube, Maps, and partner sites.
In short: It's a pay-per-click (PPC) system where advertisers bid on keywords, and they only pay when someone clicks their ad. It's designed to promote businesses, drive traffic, generate leads, or boost sales.
