Paid marketing options like search ads and display network ads allow businesses to reach massive online audiences. Search ads appear on search engines when people search for related terms, and can be targeted based on keywords, location, and user characteristics. Display ads show up on websites across Google and local ad networks' display networks, providing broad reach to relevant audiences based on interests and other attributes. While search ads rely on relevance and calls-to-action to get users to click, display ads must also disrupt and grab users' attention since they are not actively searching. Proper targeting and creative design are important for paid digital ads to effectively reach goals.
