Google Frequency: Average Ad Views Per Person

Google Frequency measures the average number of times each person saw your Google ads.

Formula

Google Frequency = Google Impressions ÷ Reach

Formula Components

Metadata
Type	Number
Data Source	Google Ads
Aggregation	Ratio

Example

A skincare brand running Google Display campaigns sees 125,000 impressions reaching 25,000 unique users during a product launch.

Metric	Value	Calculation
Google Impressions	125,000	Total ad displays
Reach	25,000	Unique viewers
Google Frequency	5.0	125,000 ÷ 25,000

Each person saw the ad an average of 5 times during the campaign.

How It Works

Google calculates frequency by dividing total impressions by the number of unique users reached. This metric only counts unique people—if someone sees your ad on multiple devices, they’re counted once. High frequency can lead to ad fatigue, reducing campaign effectiveness over time.

When to Use

Scenario	Action
Frequency above 7-10	Refresh creative or expand targeting to reduce ad fatigue
Low frequency with high reach	Increase frequency caps to boost message retention
Brand awareness campaigns	Target 3-5 frequency for optimal recall
Retargeting campaigns	Monitor closely—higher frequency acceptable but watch for diminishing returns
