PPC
Also: PPC, Pay Per Click, Cost Per Click advertising, CPC advertising, Coût par clic, Paiement au clic
Pay Per Click (PPC) is a digital advertising model where you pay only when a user clicks your ad, not when it is merely displayed.
What It Is
PPC (Pay Per Click) is a digital advertising pricing model in which advertisers pay a fee each time someone clicks one of their ads. Instead of paying for exposure (impressions), you pay for a measurable action: the click that sends a visitor to your site or landing page. PPC is the dominant billing model on search engines, social platforms, and many display and retargeting networks.
Ads are typically ranked through a real-time auction that combines your bid with an ad quality or relevance score, so the highest bidder does not always win. This means better creative and landing pages can lower your effective cost.
Why it matters
- Budget control: You spend only on engaged users, and you can cap daily or monthly budgets.
- Measurability: Every click, conversion, and euro spent is traceable, making it one of the most accountable marketing channels.
- Speed: Unlike SEO, PPC delivers traffic almost immediately once campaigns go live.
- Financial discipline: Because costs tie directly to outcomes, PPC connects marketing spend to unit economics.
How it is used in practice
1. Keyword or audience selection: Choose search terms or audience segments to target.
2. Bidding: Set a manual bid or use automated strategies (target CPA, target ROAS).
3. Ad creation: Write ads and design landing pages.
4. Measurement: Track clicks, conversion rate, and cost per acquisition.
5. Optimization: Pause weak keywords, raise bids on winners, refine creative.
Key metrics include CPC (cost per click), CTR (click-through rate), conversion rate, CPA (cost per acquisition), and ROAS (return on ad spend).
Worked Example
Suppose you run a B2B training campaign:
- Average CPC: 3 euros
- Clicks bought: 1,000, so spend = 3,000 euros
- Conversion rate: 4 percent, giving 40 leads
- CPA = 3,000 / 40 = 75 euros per lead
If 10 percent of leads become customers worth 1,500 euros each, you gain 4 customers = 6,000 euros in revenue against 3,000 euros spent, a 2x ROAS. If CPA rose to 200 euros while customer value stayed flat, the channel would turn unprofitable, signaling a need to cut bids or improve conversion.
This makes PPC a tight feedback loop between spend, data, and financial return.
Frequently asked questions
What does PPC mean in digital advertising?
PPC (Pay Per Click) is a pricing model where an advertiser pays a fee each time someone clicks an ad, rather than paying for impressions. It is the dominant billing model on search engines, social platforms, and many display and retargeting networks. You pay for a measurable action: the click that sends a visitor to your site or landing page.
Does the highest bidder always win the ad auction?
No. Ads are ranked through a real-time auction that combines your bid with an ad quality or relevance score, so a lower bid with stronger creative and a better landing page can outrank a higher one. This is why improving ad copy and landing page experience lowers your effective cost per click.
What is the difference between PPC and SEO in terms of results?
PPC delivers traffic almost immediately once campaigns go live, while SEO builds visibility over time without paying per click. PPC gives you budget control with daily or monthly caps and traceable spend, but the traffic stops when the budget stops. The two are usually run as complements, not substitutes.
Which metrics should I track to judge a PPC campaign?
Five metrics cover the essentials: CPC (cost per click), CTR (click-through rate), conversion rate, CPA (cost per acquisition), and ROAS (return on ad spend). CPC and CTR tell you how efficiently you buy attention; conversion rate, CPA and ROAS tell you whether that attention turns into profitable business.
How do I calculate whether a PPC campaign is profitable?
Divide total spend by the number of conversions to get CPA, then compare it to the value of a customer. Example: 1,000 clicks at 3 euros CPC costs 3,000 euros; a 4 percent conversion rate gives 40 leads, so CPA is 75 euros per lead. If 10 percent of those leads become customers worth 1,500 euros each, you get 4 customers and 6,000 euros of revenue for 3,000 euros spent, a 2x ROAS.
