What the result means

Reach shows unique people exposed to the campaign. High coverage can be useful, but very high coverage with high frequency can signal saturation.

Reach = Impressions ÷ Frequency; Audience Coverage = Reach ÷ Audience Size × 100

Actual platform reach may differ because auctions, duplication, and audience overlap affect delivery.

Example calculation

1,000,000 impressions at frequency 4 estimate about 250,000 people reached.

Tips for better results

  • Balance reach with frequency.
  • Use broader audiences for incremental reach.
  • Watch saturation when coverage is high.
