      (1/5)
      1. Which metric shows how many times your ad was displayed to users?
      easy
      A. CPA
      B. Clicks
      C. Conversions
      D. Impressions

      Solution

      1. Step 1: Understand the meaning of impressions

        Impressions count how many times an ad is shown to users, regardless of interaction.

      2. Step 2: Compare with other metrics

        Clicks count interactions, conversions track actions, CPA measures cost per action, so they don't represent views.

      3. Final Answer:

        Impressions -> Option D

      4. Quick Check:

        Impressions = number of times ad is seen [OK]
      Hint: Impressions = ad views, not clicks or actions [OK]
      Common Mistakes:
      • Confusing clicks with impressions
      • Thinking conversions count views
      • Mixing CPA with impressions
      2. Which formula correctly calculates Click-Through Rate (CTR)?
      easy
      A. CTR = (Clicks / Impressions) x 100
      B. CTR = (Conversions / Clicks) x 100
      C. CTR = (Impressions / Clicks) x 100
      D. CTR = (CPA / ROAS) x 100

      Solution

      1. Step 1: Recall CTR definition

        CTR measures the percentage of people who clicked an ad after seeing it, so it's clicks divided by impressions.

      2. Step 2: Check the formula options

        Only CTR = (Clicks / Impressions) x 100 correctly divides clicks by impressions and multiplies by 100 to get a percentage.

      3. Final Answer:

        CTR = (Clicks / Impressions) x 100 -> Option A

      4. Quick Check:

        CTR = clicks ÷ impressions x 100 [OK]
      Hint: CTR = clicks divided by impressions times 100 [OK]
      Common Mistakes:
      • Swapping clicks and impressions
      • Using conversions instead of clicks
      • Confusing CPA or ROAS with CTR
      3. If an ad had 10,000 impressions, 500 clicks, and 50 conversions, what is the CPA (Cost Per Acquisition) if total spend was $1,000?
      medium
      A. $20
      B. $50
      C. $10
      D. $5

      Solution

      1. Step 1: Understand CPA formula

        CPA = Total Spend ÷ Number of Conversions. Here, spend is $1,000 and conversions are 50.

      2. Step 2: Calculate CPA

        CPA = 1000 ÷ 50 = 20 ($20).

      3. Step 3: Recalculate carefully

        1000 ÷ 50 = 20, so CPA is $20.

      4. Final Answer:

        $20 -> Option A

      5. Quick Check:

        CPA = spend ÷ conversions = 1000 ÷ 50 = 20 [OK]
      Hint: CPA = total spend divided by conversions [OK]
      Common Mistakes:
      • Dividing by clicks instead of conversions
      • Mixing up CPA with ROAS
      • Incorrect division calculation
      4. A campaign shows 2,000 clicks and 100 conversions with a total spend of $500. The reported CPA is $10. What is the error in this calculation?
      medium
      A. CPA should be $20, not $10
      B. CPA should be $50, not $10
      C. CPA should be $5, not $10
      D. CPA is correctly calculated as $10

      Solution

      1. Step 1: Calculate correct CPA

        CPA = Total Spend ÷ Conversions = 500 ÷ 100 = 5.

      2. Step 2: Compare with reported CPA

        The reported CPA is $10, which is double the correct value, so it's an error.

      3. Final Answer:

        CPA should be $5, not $10 -> Option C

      4. Quick Check:

        CPA = 500 ÷ 100 = 5 [OK]
      Hint: CPA = spend divided by conversions; check division carefully [OK]
      Common Mistakes:
      • Using clicks instead of conversions
      • Misreading total spend
      • Ignoring correct division
      5. An advertiser spent $2,000 on a campaign that generated $8,000 in revenue. If the campaign had 40 conversions, what is the ROAS and CPA? Choose the correct pair.
      hard
      A. ROAS = 0.25, CPA = $200
      B. ROAS = 4, CPA = $50
      C. ROAS = 4, CPA = $200
      D. ROAS = 0.25, CPA = $50

      Solution

      1. Step 1: Calculate ROAS

        ROAS = Revenue ÷ Spend = 8000 ÷ 2000 = 4.

      2. Step 2: Calculate CPA

        CPA = Spend ÷ Conversions = 2000 ÷ 40 = 50.

      3. Final Answer:

        ROAS = 4, CPA = $50 -> Option B

      4. Quick Check:

        ROAS = 8000 ÷ 2000 = 4, CPA = 2000 ÷ 40 = 50 [OK]
      Hint: ROAS = revenue/spend, CPA = spend/conversions [OK]
      Common Mistakes:
      • Mixing revenue with conversions
      • Swapping ROAS and CPA formulas
      • Incorrect division order
