Google Ads is a self-serve advertising platform for buying ads across Google-owned and partner inventory. It supports multiple campaign types (Search, Display, Video/YouTube, Shopping, app, and goal-based automation such as Performance Max) with auction-based pricing models commonly including pay-per-click (CPC) and pay-per-view (for some video formats).
A central value proposition is intent capture (Search ads shown when users query keywords indicating purchase or research intent), combined with broad reach across Google properties (Search, YouTube, Display Network) and automated optimization via bidding and targeting automation.
