What is CPC?

CPC (Cost Per Click) is the price paid for each click. In Search Ads it's the direct output of the auction model; in social it's a derivative of CPM and CTR. Fundamental unit of budget management — but not by itself a quality metric.

// formula

Search CPC is determined by auction: competitor bids + your Quality Score + ad extensions (Ad Rank). Higher Quality Score = lower CPC for the same position.

// bidding strategies

• Manual CPC — you set max bid per keyword. Good for small accounts.
• Maximize Clicks — Google buys most clicks per budget. Risk: low-quality clicks.
• tCPA / tROAS — conversion-focused; Google tunes CPC to hit your CPA/ROAS target.
• Maximize Conversions / Conversion Value — spends the budget for max conversions/value.

// US benchmarks (2025)

• E-commerce generic — $0.80-2.50.
• E-commerce branded — $0.20-0.60.
• Insurance / finance — $4-22 (the priciest niche).
• B2B SaaS — $3-12.
• Education / online courses — $1.50-5.

// lowering CPC

1. Quality Score lift — better CTR, relevant landing page, tight keyword grouping cut CPC 20-40%.
2. Negative keywords — block irrelevant queries; reduce search waste.
3. Long-tail keywords — "running shoes" vs "women's trail running shoes size 9" — cheaper and convert better.
4. Geo / device bid adjustments — lower bids in low-converting locations or device types.
