10.1 Core Metrics Deep Dive¶
What this page teaches: Core metrics include impressions, clicks, [[CTR]], [[CPC]], [[CVR]], spend, sales, [[ACOS]], [[TACOS]], and [[ROAS]].
Why this matters in real accounts: This topic affects money, visibility, campaign control, reporting clarity, or team execution. Understanding the business reason first makes the console steps much easier to learn.
Practical workflow: - Read the definition and linked glossary terms. - Identify what decision this topic affects. - Find the report, console screen, or input data required. - Make a small reversible change first when working in a live account. - Write down what changed and why.
Worked mini-example: Open the relevant report, check the key metric, make one small change, and note what you did and why.
Common beginner mistakes: - Skipping the context and copying tactics blindly. - Changing a live account without checking eligibility, budget, or data window. - Forgetting to log the reason behind the change.
Definition of done: - The learner can explain the topic without jargon. - The learner can name the report, console area, or data input used for this topic. - The learner can describe one safe action, one risky action, and one escalation trigger.

Complete data-filled section notes¶
Metrics are the language of PPC. Beginners should learn what each metric answers, not just memorize formulas.
| Metric | Formula | What it answers |
|---|---|---|
| CTR | Clicks / Impressions | Is the ad attractive and relevant? |
| CVR | Orders / Clicks | Does the listing convert traffic? |
| CPC | Spend / Clicks | How expensive is traffic? |
| ACOS | Spend / Ad Sales | How efficient is ad spend? |
| ROAS | Ad Sales / Spend | How much revenue per ad dollar? |
| TACOS | Spend / Total Sales | How much the business relies on ads? |
ACOS vs TACOS¶
ACOS measures ad-attributed sales only. TACOS includes organic sales. A campaign can have higher ACOS while TACOS improves if PPC helps organic rank and total revenue grows. That is why serious PPC managers look at both.
Health scorecard starter¶
| Metric | Good | Warning | Danger |
|---|---|---|---|
| ACOS | At or below target | Target + 10% | Target + 20% |
| CTR | At category norm | 75% of norm | 50% of norm |
| CVR | At category norm | 75% of norm | 50% of norm |
| Budget use | 80-100% | 60-80% | Below 60% if campaign should scale |
Break-even ACOS¶
Break-even ACOS = Gross Profit / Price
If a product sells for $50 and profit before ads is $15, break-even ACOS is 30%. Above that, ads are likely unprofitable unless there is a launch or ranking reason.
Metric interpretation¶
Low CTR usually means poor relevance, weak main image, or uncompetitive offer. Low CVR usually points to listing, price, reviews, shipping, or mismatch between keyword and product. High CPC means competition or aggressive placement/bid settings.
Operator checklist¶
- Explain the topic in plain English.
- Identify the report, console area, or input data needed.
- Make the smallest safe change first.
- Log the action, reason, and expected review date.
- Escalate if the issue touches policy, inventory, account health, or large budget changes.
