Every euro has to come back
In performance marketing every campaign owes you an answer in leads or sales, not in reach. Not "we were visible", but "this campaign brought 23 leads at 31 euros each". The opposite is brand marketing: awareness and trust that show up in leads only months later. A healthy business does both and knows what each returns.
The usual channels are Google Ads on search terms, Facebook and Instagram ads, retargeting to people who already visited your site, comparison sites, affiliates paid per sale, and email. What they share: every step from impression to sale can be measured, and so adjusted.
Four ways to pay, from being seen to selling
Per 1,000 impressions
You pay to be seen, even if nobody clicks.
- Awareness, video, Instagram
- Risk with you
Per click
You pay when someone clicks through to your site.
- Google Ads, search ads
- Risk shared
Per lead
You pay per completed form or phone call.
- Lead platforms, some affiliates
- Risk with the partner
More risk with whoever shows the ad
Performance marketing steers on the right-hand side: every euro has to bring a measurable result, even when you pay per impression or click.
First per impression, per click since 2002
Mail-order firms counted the orders each catalogue brought in long before the web. Online it became exact. In July 1996 Amazon opened its Associates program, paying websites a commission on every sale they referred: paying for results in its purest form. Google launched AdWords in October 2000, but advertisers then still paid per 1,000 impressions; paying per click arrived in 2002. Today Google and Meta steer their own algorithms on conversions: you state what a lead or a sale is worth, and the platform hunts for the people most likely to deliver it.
Three things to get right before the first euro goes out
- Tracking. A tag or Meta pixel on your site that reports a lead or a sale, loaded only after the visitor consents. In the EU no consent means no tracking, and no tracking means the algorithm learns nothing.
- A value. What is a lead worth, what is a customer worth? Without that number nobody can say whether 40 euros per lead is expensive or cheap.
- Steering. Each week, money moves from what fails to what works, judged on ROAS for a store or on cost per acquisition for a service business, and over time on the ROI of the whole.
A month of ads for a kitchen studio
Take a kitchen studio in Germany spending 1,500 euros a month on ads. It tracks every quote request and knows from its books that one request in four becomes a kitchen worth 14,000 euros on average, at a 30% gross margin.
After a month the studio sees this:
| Channel | Budget | Requests | Cost per request | Decision |
|---|---|---|---|---|
| Google search ads on "Küche nach Maß" and kitchen renovation terms | 700 euros | 14 | 50 euros | More budget |
| Instagram reels of finished kitchens | 500 euros | 6 | 83 euros | Keep, test new visuals |
| Retargeting to visitors of the price page | 200 euros | 5 | 40 euros | Keep, the list is small |
| Broad Display ads | 100 euros | 0 | none | Stop |
Next month the 100 euros move from Display to search. That is performance marketing: not more money, the same money where it works.
What you pay: budget, management and tracking
You set the ad budget yourself; Google asks for no minimum. What a click costs depends on your sector and your rivals. In the largest benchmark of 2026, covering over 13,000 US search campaigns, a click cost 5.42 dollars on average and a lead 66.69 dollars. Most European markets run lower, but the spread between sectors is wider than between countries. Figures per sector are in Google Ads cost and Facebook ads cost.
On top comes management: doing it yourself costs hours a week, an agency charges a monthly fee or a share of spend, and digital agency cost lays the models side by side. Then the one-off tracking setup: tags, consent and conversions done properly. Meta or Google Ads helps you pick where to start:
- Choose Google ifpeople already search for what you sell, such as a plumber, a kitchen or an accountant.
- Choose Meta ifpeople do not know your product yet but want it once they see it, such as a holiday home, clothing or an event.
- Choose both ifthe decision takes weeks: Meta makes you known, Google catches whoever searches later.

Where steering on numbers goes wrong
Counting only the last click. Measure only what happened right before a sale and you cut the channels that introduced people. Your sales funnel dries up at the top, and months later at the bottom.
Counting your own name. Campaigns on your company name always score well, because those people were looking for you anyway. That is not growth; report it separately.
Tracking without consent. A pixel that fires before the visitor says yes breaks EU law. A pixel that never fires teaches the algorithm nothing. Honest consent solves both.
Judging too early. With 3 leads you know nothing yet. Let a campaign reach at least 15 to 20 results before you stop or double it.
What advertisers ask about it
How is performance marketing different from digital marketing?
Digital marketing is wider: your website, SEO, social media and brand work belong to it, even when the result cannot be measured per euro. Performance marketing is the part you judge campaign by campaign on leads or sales.
Does it suit a small business?
Yes, if you can track a lead or a sale and know what it is worth. A few hundred euros a month is enough to test which channel works. Without tracking it is guessing under a pricier name.
Will an agency then work for results only?
Rarely. Most agencies charge a fee or a share of spend, because they do not control your product, price or follow-up. Pay-per-lead deals exist, but the partner usually owns those leads and sells them to others too.
Which numbers should I follow each week?
Cost per lead or per sale, ROAS for a store, the share of new customers, and over a longer period the ROI of all marketing together. Clicks and impressions are signals, not goals.
