Cost per Click (CPC)

Average cost paid per click on a paid advertisement

What is Cost per Click (CPC)?

Cost per click is the average amount paid each time someone clicks on an ad. It divides total advertising spend by the number of clicks received.

It shows how expensive it is to bring traffic to a website through paid channels. Lower is not always better, because cheap clicks from the wrong audience are worth less than expensive clicks from buyers.

How this KPI is measured

Function: Marketing
Sub-function: Paid Media
Industry: All Industries
Type: Lagging
Impact: Financial control
Unit: $
Measurement frequency: Daily / Weekly
Formula: Total ad spend / Total clicks

How to calculate it

Divide total ad spend by the total number of clicks in the same period.

For example, if a campaign spent 3,000 and received 2,000 clicks, the cost per click is 3,000 / 2,000 = 1.50.

On many platforms this is the price you pay in an auction, so it moves with competition, quality scores and targeting. Compare it by campaign, keyword and audience rather than relying on one blended figure.

Where it is used

Managing paid budgets
Estimate how much traffic a given budget will buy.
Comparing keywords and audiences
Identify which targeting choices are most expensive and whether they are worth it.
Monitoring competition
A rising cost per click can signal more competitors bidding on the same terms.

How to improve it

Improve ad relevance and qualityBetter-matched ads and landing pages usually earn cheaper clicks on auction platforms.
Refine keywords and targetingRemove expensive terms that do not convert and add specific, lower-competition ones.
Adjust bids by performanceBid more where clicks turn into customers and less where they do not.
Use negative keywordsExclude search terms that attract clicks without buying intent.
Watch cost per result as wellJudge whether a more expensive click is justified by what it converts into.

Tips and common mistakes

Do not chase the cheapest clicks. Cost per lead or per sale is the measure that matters.
Compare against your own trend, since costs differ enormously by industry and keyword.
Check by device and location, since averages can hide very different costs.
