Which of the following is true when purchasing ad placements on an advertising network?

Advertising networks act as intermediaries, allowing advertisers to purchase ad placements across many websites simultaneously. A key benefit they offer is providing performance data, such as click-through rate (CTR), which measures how often users click on an ad after seeing it. This data is crucial for advertisers to evaluate the effectiveness of their campaigns and optimize their spending. The other options are incorrect because: "You always need to contact the owner of the website to buy ads on their page" is false. Advertising networks streamline this process, eliminating the need for direct contact with individual website owners. "The network provides names of the people who click your ad" is also false. Due to privacy regulations and ethical considerations, advertising networks do not provide personally identifiable information (PII) of users who interact with ads. They provide aggregated, anonymous data.
