The challenge

Lumen Health relied on a few ads that had worked a year earlier. Results were slipping, targeting was broad, and there was no process for testing new ideas.

  • Top ads were more than a year old.
  • Audiences were broad and overlapping.
  • Demo requests were getting more expensive.
  • No structured creative testing existed.
