3 Key Metrics in Digital Advertising
1. CTR (Click-Through Rate)
CTR shows the percentage of people who click on your ad.
Formula:
CTR = (Clicks / Impressions) × 100
Example:
- 1,000 people see the ad
- 50 people click
👉 CTR = 5%
What Does a High CTR Mean?
- The ad grabs attention
- The hook and visuals are effective
What Does a Low CTR Mean?
- The ad is not relevant
- Incorrect targeting
2. Conversion Rate
Conversion rate measures how many users take action after clicking.
Formula:
Conversion Rate = (Conversions / Clicks) × 100
Example:
- 100 clicks
- 10 purchases
👉 Conversion rate = 10%
Factors That Affect Conversion Rate:
- Landing page quality
- Offer attractiveness
- Trust elements
3. ROI (Return on Investment)
ROI shows the actual profit generated from ads.
Formula:
ROI = (Profit – Ad Cost) / Ad Cost × 100
Example:
- Sales = RM1,000
- Ad cost = RM200
👉 ROI = 400%
What Does a High ROI Mean?
- Ads are profitable
What Does a Low or Negative ROI Mean?
- Loss or inefficiency
The Role of Each Metric
| Metric | Function | Focus |
|---|---|---|
