This lesson covers the most commonly used automated bid strategies: Maximize Clicks (gets as many clicks as possible within budget, good for driving traffic), Target CPA (Cost Per Acquisition — aims to get conversions at a specific target cost), and Target ROAS (Return on Ad Spend — aims to hit a specific revenue-to-spend ratio, ideal for e-commerce). Choosing the right strategy depends on your campaign goal and how much conversion data you already have, since strategies like Target CPA need sufficient historical data to work effectively.
