Understanding Advertising Metrics

CPM (Cost Per Mille)

CPM represents the cost an advertiser pays for every 1,000 impressions (views) of their advertisement. It's commonly used for brand awareness campaigns.

Formula: CPM = (Total Cost / Total Impressions) × 1000

CPC (Cost Per Click)

CPC is the amount paid each time a user clicks on an advertisement. Popular in search advertising and performance marketing.

Formula: CPC = Total Cost / Total Clicks

CPA (Cost Per Action)

CPA measures the cost for each desired action (purchase, signup, download). It focuses on conversions rather than clicks or impressions.

Formula: CPA = Total Cost / Total Conversions

eCPM (Effective Cost Per Mille)

eCPM standardizes different pricing models to compare performance across campaigns. It shows revenue per 1,000 impressions regardless of billing method.

Formulas:

From CPC: eCPM = CTR × CPC × 1000

From CPA: eCPM = CTR × CVR × CPA × 1000

Key Performance Indicators

CTR (Click-Through Rate)

The percentage of people who click on your ad after seeing it. Higher CTR indicates more relevant and engaging ads.

Formula: CTR = (Clicks / Impressions) × 100%

CVR (Conversion Rate)

The percentage of clicks that result in a desired action. Measures how effective your landing page is at converting visitors.

Formula: CVR = (Conversions / Clicks) × 100%

Frequently Asked Questions about CPM 계산기

? 사례 1: 대학생이 티스토리 블로그 운영 시

“내 블로그에 광고를 달았는데, 얼마씩 벌고 있는지 모르겠어요.” → 실제로는 20만 원 광고비로 40만 회 노출, 8천 회 클릭, 400건 전환이 나왔어요. 이때 계산기로 eCPM을 계산하면: eCPM = CTR(2%) × CVR(5%) × CPA(5000원) × 1,000 = 500원 즉, 1,000회 노출당 평균 500원 수익이라는 결론! 이걸 보고 “아, 이건 광고 모델이 잘 맞네”라고 판단했죠.

? 사례 2: 자유직업자(프리랜서)가 고객사와 협상할 때

“저는 CPC 기준으로 광고를 돌렸는데, 고객은 CPM 기준으로 비교하더라구요.” → 계산기로 직접 변환해보니: CPC 100원, CTR 3%, CVR 10% → eCPM = 300원 이렇게 해서 다른 기준으로도 비교 가능하다는 걸 보여줬어요. 결과적으로 고객도 이해가 되고, 더 신뢰받는 제안이 됐습니다.
