How do cookies function in digital advertising?

Cookies play a crucial role in digital advertising by tracking online behavior and enabling targeted advertising. When a user visits a website, cookies are small pieces of data stored on their device. These cookies collect information such as pages visited, time spent on each page, and interactions with content. This data is then utilized to build user profiles, which helps advertisers better understand their audience's preferences and behaviors.

With this understanding, advertisers can deliver more relevant ads to users, increasing the likelihood of engagement. Targeted advertising powered by cookies helps to create a more personalized experience, ensuring that users see ads that are aligned with their interests rather than generic advertisements.

In contrast, the other options presented do not accurately depict the primary function of cookies in digital advertising. For instance, they do not have the ability to prevent users from seeing ads, create high-quality content, or measure website load speed. Cookies specifically focus on tracking user interactions and behaviors, making targeted advertising their main functional purpose.
