What is the primary use of 3rd party tags?

The primary use of third-party tags is for broader research and targeting. Third-party tags are small pieces of code that are inserted into a website or app, allowing for the collection of data from users who visit that site. This data can then be used to gain insights into user behavior, preferences, and demographics, which are invaluable for marketers looking to create targeted advertising campaigns.

By leveraging this information, brands can tailor their marketing strategies to reach specific audiences more effectively and optimize ad performance across multiple channels. This capability of gathering extensive data from various sources is what makes third-party tags particularly powerful in digital marketing, enabling advertisers to extend their reach and implement strategies that engage users in a more personalized manner.

The other options focus on functionalities that are not the primary intent of third-party tags. For instance, limiting access to data is more related to privacy and security measures rather than the core purpose of third-party tracking. Similarly, internal campaign tracking and asset management are specific actions that typically utilize first-party tags or are handled through different tools altogether.
