How These Metrics Relate

  • Impressions counts every time your ad appears on screen
  • Reach counts unique individuals, regardless of how many times they saw it
  • Frequency = Impressions ÷ Reach — shows average views per person
  • CPM = Spend ÷ Impressions × 1,000 — measures delivery cost efficiency
High frequency can signal ad fatigue, while low CPM indicates efficient reach.

​
Choosing the Right Metric

  • Awareness campaigns: Use Impressions and Reach to measure visibility
  • Ad fatigue detection: Monitor Frequency—above 3-4 may indicate fatigue
  • Cost efficiency: Compare CPM across campaigns to find efficient delivery
  • Audience expansion: Track Reach growth to measure new audience acquisition
