What it measures
Google Ads reach is the number of unique people your budget exposes your ads to, derived from impressions and the average frequency each person sees the ad.
Formula
Impressions = Budget ÷ CPM × 1,000 · Reach = Impressions ÷ Frequency
Worked example
A $5,000 budget at a $7 CPM buys about 714,286 impressions, reaching roughly 238,095 unique people at a frequency of 3.
Typical benchmarks
- Display / YouTube CPM
- $2-$15
- Awareness frequency
- 2-3
- Best reach networks
- Display, YouTube
How this calculator works
Impressions = budget ÷ CPM × 1,000. Reach = impressions ÷ frequency. Display and YouTube CPMs are usually lower than Search, making them efficient for awareness.
Frequently asked questions
Which Google networks are best for reach? +
The Display Network and YouTube offer large, low-CPM inventory ideal for awareness, while Search is better for intent-driven demand capture.
How is reach different from impressions? +
Impressions count every ad view; reach counts unique people. Frequency is the average impressions per person.
Which Google campaign type maximizes reach? +
Demand Gen, Display, and YouTube campaigns offer the largest, lowest-CPM inventory for unique reach, while Search is built for intent capture, not broad awareness.
What is effective frequency? +
It's the number of exposures needed before a message sticks — often cited as 3-7 for awareness. Below it, ads underperform; above it, you risk waste and fatigue.
How is unique reach measured on YouTube? +
Google estimates unique users and uses Unique Reach reporting and frequency caps to limit how often the same person sees your video ads.
