Digital advertising refers to the promotion of products or services using the internet and digital platforms. This includes various formats such as social media ads, search engine marketing, and display banners. Businesses use these methods to reach a wider audience, targeting specific groups based on their interests and online behavior. One of the key advantages of digital advertising is its ability to track performance in real-time. Advertisers can see how many people clicked on their ads, how long they engaged with the content, and even if they made a purchase. This data helps companies like Google and Facebook optimize their campaigns for better results.
