CPC
Paid MediaAlso: Cost Per Click · Pay Per Click · PPC
Quick definition
CPC stands for cost per click. It is the average amount you pay each time someone clicks on a paid ad. Calculated as total ad spend divided by total clicks in the same period. CPC is an efficiency metric for media buying, not a measure of business outcome.
CPC on its own tells you media efficiency, not business outcome. Pair with your conversion rate to get CPA, which is the number that actually matters.
How it varies across Australia
CPC in the Australian market runs higher than US equivalents across most categories. The auction pool is smaller, the number of advertisers competing is lower, but the cost-per-business is concentrated. Finance, legal and insurance keywords sit at the higher end. Retail and lifestyle keywords sit lower. The gap between categories is wide.

CPC is the price of a visit, not the price of a customer. That distinction sounds obvious but gets lost constantly in paid-media reporting.
Every ad auction sets CPC through a bidding system. Google, Meta and LinkedIn each use their own flavour of the same idea: you bid a maximum, the platform weighs your bid against your quality score, and the winner pays roughly one cent more than the next bidder. The 'average CPC' in your dashboard is that mechanism averaged across every click in the period.
The number that tells you whether your CPC is acceptable is your conversion rate. A high CPC on a page that converts well can produce a perfectly healthy CPA. A low CPC on a page that bounces at 90% is expensive where it counts.
CPC also varies dramatically by match type, device, placement and audience. A search keyword on exact match and a display ad in a content network can both be called CPC but they are buying fundamentally different things. Averaging them together hides the truth.
A low CPC is a consolation prize if the traffic never buys anything.
How to calculate it
CPC = Total ad spend ÷ Number of clicks
Worked example. You spent $3,200 on Google Search last month and received 1,840 clicks. CPC = $3,200 ÷ 1,840 = $1.74. If 46 of those clicks became leads, your CPA = $3,200 ÷ 46 = $69.57. The CPC alone told you nothing. The CPA told you something useful.
The Australian context
Australian search auctions are structurally more expensive per click than US auctions in most categories. The pool of competing advertisers is smaller, but the demand for premium placements is concentrated among a handful of industries. Financial services, legal, real estate and healthcare keywords routinely sit at the expensive end of the global range.
Australian advertisers also contend with a smaller keyword universe for local queries, which pushes spend toward broader terms with lower purchase intent. The result is that Australian CPC often buys lower-intent traffic than the equivalent spend in the US. That is worth factoring into landing page and offer strategy before blaming the platform.

Common questions
What is a good CPC in Australia?
There is no universal good CPC. The number is only meaningful relative to your conversion rate and the value of what you are acquiring. A high CPC that produces a profitable CPA is fine. A low CPC that never converts is expensive. Check the CPA, not the CPC.
How is CPC different from CPM?
CPC charges you per click. CPM, which stands for cost per thousand impressions, charges you per time your ad is shown. CPC suits direct-response campaigns where clicks matter. CPM suits brand campaigns where reach and visibility matter more than immediate action.
Why is my CPC higher than the industry benchmark?
Four common causes: your quality score is low, you are bidding on high-competition keywords, your audience targeting is too narrow for the auction, or you are comparing against a benchmark that uses a different match type mix. Check quality score first.
Does lowering CPC always improve performance?
No. Lowering CPC by broadening targeting or relaxing match types usually brings in lower-intent traffic that converts worse. Your CPA can rise even as your CPC falls. Optimise for downstream outcomes, not click price.
