✅ 30 High CPC Keywords – The Topics That Pay Over 500 KRW Per Click

1. “Who Really Makes Money with AdSense?”

Consider these two cases:

• A blogger with 1,000 daily visitors but only ₩1,500 in revenue
• Another with 200 visitors but ₩7,000 in revenue

What’s the difference? Just one thing:

👉 CPC (Cost Per Click)

AdSense works like this: advertisers pay to run ads, and publishers (like us) earn a commission when users click them.

This means that the higher the conversion rate for a topic, the more advertisers are willing to spend.

• Insurance → Click → Phone number submitted → Contract signed
• Financial products → Click → Application completed
• Health supplements → Click → Direct purchase highly likely

That’s why some topics have much higher CPCs. The same click could earn 10x more depending on the niche.

2. What Makes a High-CPC Keyword?

✅ ① Fierce Ad Competition
More advertisers = higher CPC

✅ ② High Conversion Rate
Clicks easily lead to sign-ups, applications, or purchases → Advertisers are happy to spend more

✅ ③ Money-Driven Industries
Insurance, finance, real estate, education, healthcare → Acquiring one customer can cost companies hundreds of thousands of won

The moment you target these niches, your AdSense earnings can jump 3–5x.
