What is CPC and why does it matter?

CPC (Cost Per Click) is what you pay each time someone clicks your ad. It's the core pricing model for Google Ads, Facebook Ads, and LinkedIn Ads. Understanding your CPC relative to your conversion rate and customer value tells you whether a campaign is actually profitable — not just generating clicks.

What is a good Google Ads CPC?
It depends heavily on industry. Legal and finance keywords average $5–$10 CPC. eCommerce averages $0.50–$2. B2B SaaS sits at $3–$8. Always compare CPC against your conversion rate and customer lifetime value.

CPM vs CPC — which should you use?

Use CPC (cost per click) when your goal is direct response — website visits, sign-ups, purchases. Use CPM (cost per 1,000 impressions) when your goal is brand awareness and you want maximum visibility. For most small businesses, CPC campaigns on Google Search deliver the highest ROI because you only pay when someone shows intent.
