Cost per Click (CPC)

What is Cost per Click (CPC)?

Cost per Click (CPC) is the fundamental billing model in Google Ads. You only pay when someone actually clicks on your ad, not for merely showing it (impression). The CPC is determined through an auction where your bid, Quality Score, and competition all play a role.

Maximum vs. Actual CPC

There's an important distinction: Your maximum CPC is the highest bid you're willing to pay. The actual CPC is what you really pay — often significantly less. Google calculates the actual CPC so you only pay the minimum needed to outbid the advertiser below you.

What Influences CPC?

• Competition: The more advertisers bidding on a keyword, the higher the CPC
• Quality Score: A higher Quality Score lowers your actual CPC
• Industry: Lawyers often pay €5-15 per click, local services €1-3
• Device type: Mobile clicks can be cheaper or more expensive

How to Lower Your CPC

Improve Quality Score: The most effective lever. Each additional Quality Score point can reduce CPC by 10-20%.

Use long-tail keywords: More specific keywords like "dentist Munich implants cost" often have lower CPCs than general terms like "dentist Munich."

Bid adjustments: Reduce bids for times, devices, or locations with poor performance.

Pro Tip: Don't just focus on the lowest CPC — focus on the best ROI. A €10 click that leads to a €1,000 order is better than 10 clicks at €1 each without conversion.
