Paid MediaAlso: Pay-Per-Click · Paid Search · Paid Advertising
Quick definition
PPC stands for pay-per-click. It is a model of online advertising where you pay a fee each time someone clicks your ad. PPC ads appear in search results, social feeds, display networks and shopping platforms. The most common PPC platform in Australia is Google Ads.
How it varies across Australia
PPC costs vary sharply across Australian industries. Finance, legal and insurance categories sit at the expensive end. Retail and hospitality sit at the lower end. The cost per click is only half the picture. What matters is whether the click converts at a cost that makes the channel profitable.

The price paid each time someone clicks an ad. Determined by auction, not a fixed rate.
Google's rating of ad relevance, expected click-through rate and landing page experience. Higher scores lower your CPC.
Your position in the auction. Determined by bid multiplied by Quality Score, not bid alone.
Revenue generated per dollar of ad spend. The primary efficiency metric for ecommerce PPC.
Total ad spend divided by conversions. The metric that decides whether PPC is actually working.
What it actually means
PPC is the simplest idea in digital advertising: you pay when someone clicks. An auction runs in milliseconds every time a search happens or an ad placement opens. You bid. Others bid. The platform multiplies your bid by a quality signal and assigns a position. You pay only if someone clicks the result.
The appeal is immediacy. Turn on a campaign today, get traffic today. Compare that to SEO (Search Engine Optimisation), where you might wait months to see movement. For new products, time-sensitive offers or businesses still building organic presence, PPC fills the gap.
The catch is equally clear. The traffic is rented. When the budget runs out at midnight, the clicks stop. Build a business entirely on PPC and you are one budget cut away from zero visibility. The businesses that use PPC well treat it as an acquisition engine that runs in parallel with owned and earned channels, not as a substitute for them.
PPC also rewards precision over volume. A well-structured campaign with tight keyword groups, matched landing pages and a clear conversion goal routinely outperforms a larger spend spread across vague targeting. The platform rewards relevance with lower costs. Sloppy campaigns pay more and convert less.
PPC rents your audience. The moment you stop paying, you disappear. That is the deal.
How it shows up
PPC shows up in your ad account as clicks, impressions, click-through rate and spend. It shows up in your analytics platform as paid traffic sessions. It shows up in your CRM as leads or customers with a paid-search source.
The metric chain that matters: impression share tells you how much of the available auction you are capturing. Click-through rate (CTR) tells you whether the ad is compelling. Conversion rate tells you whether the landing page delivers on the ad's promise. CPA tells you whether the whole chain is profitable. Each number diagnoses a different part of the funnel.
The Australian context
Australian PPC markets are smaller than US or UK equivalents, which affects how the auction behaves. In some categories there are few enough active advertisers that a well-structured campaign can achieve strong positions at moderate spend. In others, particularly finance, legal and home services, a small number of large national advertisers drive costs well above what smaller players can sustain.
Google Ads dominates Australian search advertising. Microsoft Advertising has a smaller but meaningful share, particularly on older demographics and desktop. Meta's advertising sits in a different auction entirely but is often grouped under PPC in agency reporting.
Australian Consumer Law (ACL) applies to PPC ads in the same way it applies to any advertising. Price claims, comparative claims and testimonials in ad copy all carry compliance obligations. This matters more than most PPC practitioners acknowledge.

Common questions
What is PPC in simple terms?
PPC stands for pay-per-click. You create an ad, set a budget, and pay only when someone clicks the ad. The most common form is search ads on Google, where your ad appears above or below the organic search results for keywords you bid on.
How is PPC different from SEO?
PPC puts you at the top of search results immediately but stops the moment your budget does. SEO builds organic rankings over months but the traffic continues without ongoing spend. Most businesses need both running in parallel rather than choosing one over the other.
How much should an Australian business spend on PPC?
There is no universal answer. Start with enough budget to generate statistically meaningful conversion data, usually at least a month of spend at your target CPA multiplied by the minimum conversions needed to optimise. Underfunding a campaign produces data too thin to improve from.
Why did my PPC costs go up without me changing anything?
The PPC auction is dynamic. If a competitor increased their bid, if seasonality lifted demand, or if Google adjusted Quality Scores across your account, your costs move. Costs rising without a change on your end is normal, not a bug.
