The DAA Principles cover two types of entities—first parties and third parties—that deliver relevant advertising to computers or devices in ways that enrich the consumer online experience. These resources are designed to help companies understand their responsibilities under the DAA Principles and provide implementation guidance. It is possible that a single company or organization may operate in both categories, depending on what activity is being undertaken at a specific time. For this reason, it is important to consider requirements that may apply to your business across the two types of entities.
