🎯 Key Takeaway
Reach Rate = (Reach ÷ Total Followers) × 100. Reach measures the number of unique users who saw your content, while impressions count total views (including repeat views). A higher reach rate indicates your content is effectively reaching your audience.
1. What is Reach?
Reach is the number of unique users who have seen your content. It's one of the most important metrics in social media marketing and advertising because it tells you how many individual people your message has touched.
- Unique count: Each person is counted only once, regardless of how many times they saw your content
- Awareness metric: Measures how widely your content is distributed
- Platform-reported: Provided by social media analytics
- Time-bound: Usually measured per post, day, week, or month
💡 Why Reach Matters
- Brand awareness: More reach = more people know about you
- Campaign performance: Indicates content distribution success
- Audience growth: Shows if you're expanding beyond current followers
- Ad efficiency: Helps optimize advertising spend

5. Worked Examples
Example 1: Calculate Reach Rate
📝 Problem
Your Instagram post reached 8,500 people and you have 25,000 followers. What is your reach rate?
Reach Rate = (Reach ÷ Followers) × 100
Reach Rate = (8,500 ÷ 25,000) × 100 = 34%
Answer: Your reach rate is 34%, which is excellent! It means 34% of your followers saw your post.
Example 2: Calculate Frequency
📝 Problem
Your ad campaign generated 150,000 impressions and reached 50,000 unique people. What is the average frequency?
Frequency = Impressions ÷ Reach
Frequency = 150,000 ÷ 50,000 = 3.0
Answer: On average, each person saw your ad 3 times.
Example 3: Calculate Cost Per Reach
📝 Problem
You spent $2,000 on a Facebook campaign that reached 125,000 unique users. What is your cost per reach (CPR)?
CPR = Total Spend ÷ Total Reach
CPR = $2,000 ÷ 125,000 = $0.016
CPM = $0.016 × 1,000 = $16 per 1,000 reach
Answer: You paid $0.016 (1.6 cents) to reach each unique person, or $16 per 1,000 people.
