What advantage does an agency gain by hosting tags for their campaigns?

Hosting tags for campaigns provides agencies with enhanced flexibility to manage creative assets effectively. This flexibility allows agencies to make real-time updates or changes to creatives without needing to republish or redistribute the entire campaign. By hosting the tags, the agency can easily control when and how creatives are served to users, respond to performance data, and apply optimizations in a timely manner.

Having this level of management ensures that campaigns can be adjusted rapidly to improve performance, utilize A/B testing more efficiently, and tailor messaging to specific audience segments without significant delays. This capability ultimately contributes to better campaign management and outcomes.

The other options suggest limitations or disadvantages in essence. For instance, having less control over creative assets, an increased dependency on third-party services, or reducing the campaign budget do not align with the primary benefits that hosting tags provides to the agency, which centers on enhanced control and adaptability in managing campaign assets.
