Core Metrics You Must Understand

Let’s break down the most important ad metrics and what each one tells you:

---

1. Impressions

What it is: How many times your ad was shown

• High impressions = good reach
• Too high with no results = wrong targeting or weak creative

---

2. Reach

What it is: Number of unique people who saw your ad

• Helps understand audience saturation
• If reach stays low = increase budget or audience size

---

3. Click-Through Rate (CTR)

What it is: Percentage of people who saw the ad and clicked

Formula:
CTR = (Clicks ÷ Impressions) × 100

• Good benchmark: 1%+
• Low CTR = weak creative or irrelevant targeting
• High CTR = strong interest or curiosity

---

4. Cost Per Click (CPC)

What it is: How much each click cost

Formula:
CPC = Spend ÷ Clicks

• Lower CPC = better efficiency, but make sure clicks are quality
• High CPC may be due to poor ad relevance or audience competition

---

5. Conversion Rate

What it is: Percentage of people who clicked and then converted (lead, sale, booking)

Formula:
Conversion Rate = (Conversions ÷ Clicks) × 100

• Benchmark depends on industry (2–10% is common)
• Low rate = weak landing page or unqualified traffic

---

6. Cost Per Conversion / Cost Per Lead (CPA or CPL)

What it is: How much you pay for each lead or sale

Formula:
CPA = Spend ÷ Conversions

• Your most important metric in most campaigns
• Optimize your creatives, landing page, and targeting to lower this

---

7. Return on Ad Spend (ROAS)

What it is: How much revenue you earned for every $1 spent on ads

Formula:
ROAS = Revenue ÷ Ad Spend

• Break-even ROAS = 1.0
• Above 2.0 = strong profitability
• Below 1.0 = losing money (unless using for loss-leader/funnel entry)

---

8. Frequency (Meta-specific)

What it is: Average number of times someone saw your ad

• Frequency >3 = risk of ad fatigue
• High frequency + declining CTR = time to refresh creatives

---

9. Quality Score / Relevance Score

What it is: Platform’s internal rating of ad quality (based on engagement, CTR, feedback)

• Better score = lower costs and better delivery
• Low score = weak creative, poor targeting, or bad user experience

---

How to Analyze Ad Performance in Practice

Step 1: Look at CTR

Are people engaging with the ad? If CTR is low:

• Improve your hook
• Change the image or video
• Refine the offer

---

Step 2: Look at CPC

Are you paying too much for each click?

• Lower CPC = better delivery or less competitive audience
• High CPC = test new audiences or creatives

---

Step 3: Check Conversion Rate

Are your landing pages doing their job?

• If you have high CTR but low conversions, fix the landing page, form, or offer

---

Step 4: Evaluate CPA or ROAS

Is the campaign profitable?

• If not, check where the drop-off is: ad, page, or follow-up?

---

Step 5: Identify Trends

Use 3–7 day windows to compare:

✅ CTR trend
✅ Cost per result trend
✅ Lead quality feedback from the client

Don’t panic over 1-day spikes—look at the trend over time.

How to Present Metrics to Clients

Use clear, plain language:

Instead of	Say
“CTR is 0.8%”	“Less than 1 in 100 people are clicking—let’s improve the ad headline.”
“ROAS is 3.5”	“You earned $3.50 for every $1 spent. Great result—let’s scale it.”
“CPA is $27”	“Each lead cost $27. We’re under the $30 target, so we’re on track.”

Use screenshots, dashboards (Looker Studio), or weekly email summaries. Focus on what the numbers mean, not just the numbers themselves.

Common Mistakes to Avoid

🚫 Focusing only on CTR without checking conversion rate
🚫 Ignoring frequency or ad fatigue
🚫 Not tracking conversions at all
🚫 Overreacting to short-term dips
🚫 Reporting only “vanity metrics” like likes or reach
