Pay per Click (PPC)

Pay per click (PPC) is an advertising pricing model in which clicks form the basis of payment. The alternative wording PPC (Pay-Per-Click) means the same thing. The model describes what is paid for; it guarantees neither a successful page visit nor a qualified enquiry or purchase.

Pay per Click (PPC) explained

PPC can be used for different advertising formats. It is therefore not a separate channel and is not inherently limited to search ads or keywords. The booking terms matter: which clicks count, how their price is determined and how adjustments are handled.

CPC means cost per click. Average CPC is the included click costs divided by the corresponding clicks. A calculated CPC can also serve as a comparison metric even when the media itself was not bought on a click basis. Name the pricing model and reporting metric separately.

A click alone says little about its quality. People can click accidentally, fail to load the page or expect a different offer. Platforms assess detected invalid activity under their own methods. A click without a conversion is not automatically fraud, and filtering does not prove that every problem was detected.

A complete assessment includes creative, management and follow-up costs alongside media. Examine the journey from the advertising promise to the actual outcome. This helps establish whether paid interactions serve the task and where improvement is useful.

Examples

Hypothetical application

For the same period, a reports 1,000 billable clicks and €300 in click costs. Average CPC is €0.30. If those interactions yield twelve enquiries qualified under defined criteria, media cost per qualified enquiry is €25. This illustrative calculation excludes other costs.

Key Points

PPC describes pricing, not business success.
Calculate CPC with consistent costs and clicks.
Add interaction quality and complete effort.

Practical application

Document the click definition, pricing and adjustment process. Test redirects and destinations on real devices. Connect click-cost reporting with a clear definition of qualified outcomes.

Useful measures

Average CPC

Divide defined click costs by the corresponding clicks.

Qualified outcomes

Record relevant actions using clear criteria and known measurement limits.

Total costs

Include other activities and expenses relevant to the decision.

Common mistakes

Equating clicks with unique people or purchases.
Omitting production and management costs from the business assessment.
Comparing CPC figures calculated on different bases.
