How does affiliate marketing work and who is involved in the process?
Affiliate marketing involves three main participants: the advertiser (merchant), the promoter (affiliate) and the end user (customer). An advertiser offers a product or service and wants to increase sales, an affiliate promoter promotes these products on their channels (websites, blogs, social networks), while the customer converts through an affiliate link.
The affiliate promoter uses a unique link that allows you to track user behavior. When someone clicks on that link and buys a product, the system automatically records sales and assigns a commission to the affiliate partner. Everything is based on transparency and tracking, and the technology ensures that every sale is properly recorded.
This model is a win-win for everyone involved – the advertiser gets new customers without additional advertising costs upfront, the affiliate earns a commission, and the customer often receives additional information or discounts.
It is important to emphasize that affiliate marketing is not a quick overnight profit, but requires planning, building trust, and consistency in content creation.
What are the most common affiliate marketing models?
Affiliate marketing can work through different models , and each of them has a specific way of calculating commission. Choosing the right model depends on the type of product or service, the goals of the advertiser, and the role that the affiliate partner plays in the sales process. Understanding the difference between models is key to successfully choosing a strategy from both the position of an advertiser and a promoter.
The most common affiliate marketing models include:
CPA (Cost Per Action)
- The CPA model implies the payment of a commission when a user makes a certain action defined by the campaign, and not necessarily a purchase.
- These actions may include: signing up for a newsletter, opening an account, downloading an app, filling out a form, or starting a free trial.
- This model is extremely popular among advertisers because they only pay when they get a specific result.
- For affiliate promoters, the CPA model can be challenging because earnings depend on the conditions that the user must meet, not just a click or impression.
When is the CPA model used?
- Campaigns for digital tools, software, mobile apps and services with a free trial.
- Campaigns aimed at mass collection of user data or registrations.
CPL (Cost Per Lead) – Pay Per Lead
- In the CPL model, an affiliate earns money when a user expresses interest in a product or service – most often by filling out a form, downloading a free guide, or registering on the platform.
- The “lead” represents a potential customer, and the value of the lead is estimated by the advertiser based on the probability of becoming an actual customer.
- CPL is particularly effective in industries where the sales cycle is longer – such as finance, education, real estate, and the B2B sector.
- For affiliate partners, this model can be attractive because it does not require conversion into sales, but only user interest.
Advantages of the CPL model:
- Lower conversion threshold – the user does not have to spend money.
- It helps build a customer base through email lists and CRM systems.
- It can generate high value through further communication and remarketing.
CPS (Cost Per Sale) – Pay Per Sale
- CPS is the most well-known and widespread model in affiliate marketing , and the commission is paid only when the user who comes through the affiliate link makes an actual purchase.
- The amount of commission in the CPS model varies – it can be fixed (e.g. €10 per sale) or percentage (e.g. 5-30% of the total cart value).
- Advertisers love CPS because they only pay when a specific conversion occurs, while promoters love this model because it can generate substantial revenue, especially for high-value products.
- This model motivates affiliate promoters to create quality, informative content that educates and reassures the user before making a purchase.
Examples of where the CPS model is used:
- On e-commerce platforms
- SaaS and online services that offer direct purchase or subscription
- High-margin products, such as online courses, premium software, and luxury goods
Model comparison: CPA vs. CPL vs. CPS
| Criterion | CPA | CPL | CPS |
|---|---|---|---|
| When is it paid? | After the completion of the action | When a user becomes a lead | After the purchase is made |
| Suitable for | Digital services, applications | B2B, finance, education | E-commerce, SaaS |
| Risk to the advertiser | Low | Moderate | Low |
| Earning potential for an affiliate | Medium to high, depending on the action | Stable and predictable | Potentially high, but unstable |
Benefits of Affiliate Marketing for Businesses and Promoters
Affiliate marketing offers a number of benefits to both advertisers and affiliates. Thanks to digital channels, the possibilities are almost limitless.
1. Low upfront costs and lower risk
For businesses, affiliate marketing means that they only pay for actual results – sales or leads. There are no classic upfront advertising costs, which makes this model profitable even for small brands.
Affiliate promoters can also start with minimal investment, especially if they already have a built audience on a blog or social media.
2. Passive income and scalability
One of the biggest benefits for affiliates is the ability to earn passive income. Once quality content is put up, it can continuously generate clicks and conversions without any extra effort.
In addition, affiliate marketing is easily scalable – the more content you have, the higher the chance of making more profits.
3. Measurement and monitoring of results
Digital platforms allow you to track campaigns in detail – you can see the number of clicks, conversions, traffic sources and more. This makes it easier to optimize the strategy.
Affiliate marketing is therefore very transparent and allows for data-driven decision-making.
How to start affiliate marketing successfully?
Affiliate marketing may sound simple – you promote a product and earn a commission – but in practice, it’s a complex system that requires a strategic approach. Success doesn’t come overnight. It is necessary to understand the market, choose the right niche, continuously create quality content and adapt to changes in the market and in user behavior.
If you’re just starting out, it’s crucial to develop a solid foundation that will allow you to grow for the long term and earn a steady income.
1. Choose a profitable and relevant niche
The first step is to choose a niche. This is the area in which you will operate and create content. The ideal niche is one where your expertise or interest, market demand, and affiliate program availability overlap.
How to Identify a Good Niche:
- There is enough interest – users are actively searching for it.
- There is commercial value – there are products and services available that people buy online.
- It has a reasonable level of competition – it is not too saturated, but it is not inactive either.
- It is sustainable in the long run – the topics are relevant throughout the year, not just seasonally.
Examples of niches that have high potential:
- Finance and Investing (Bank Accounts, Credit Cards, Cryptocurrencies)
- Technology (web hosting, software, gadgets)
- Health and nutrition (dietary supplements, diets, mental health)
- Travel (accommodation, equipment, insurance)
- Online Education (Courses, Learning Tools, Ebooks)
Choosing a good niche affects all further steps – from the type of content you create, to the audience you attract and the income you can generate.
2. Build content that provides real value
Quality content is the foundation of affiliate marketing. People don’t want advertisements, they want information that solves their problems or helps them make a decision. Your task is to inform, advise and guide the user towards conversion – in a way that is authentic and reliable.
Features of Quality Affiliate Content:
- It clearly answers specific questions from the audience.
- It provides detailed information supported by experience, comparisons and real examples.
- It’s structured so it’s easy to read – it uses subheadings, paragraphs, and lists.
- It includes a call to action (call to click, sign-up, purchase) that fits naturally into the context.
Types of content that work best in affiliate marketing:
- Reviews of products and services
- Comparisons (e.g. “X vs. Y – which is better for beginners?”)
- Guides & Tutorials (“How to Choose the Best VPN for Travel?”)
- Lists of recommendations (“Top 10 Time Management Tools”)
- Case studies (“How I saved 100 euros a month using the X app”)
It’s important that the content is original and reflects your expertise or experience, as this builds trust with your audience.
3. Optimize content for SEO, AEO, and AI systems
Content optimization allows users to find you through search engines like Google, but also through new AI systems that generate responses from multiple sources. Your content must be structured, informative, and clear in order to be suitable for display in AI system responses and Featured Snippets positions.
SEO basics that need to be covered:
- Research keywords using tools like Ubersuggest, Ahrefs, Semrush, or Google Keyword Planner.
- Include the main keyword in the title, subheadings (H2, H3), URL, meta description, and introductory paragraph.
- Use internal and external links for better ranking and user experience.
- Ensure page loading speed and mobile customization.
For AEO, AIO and GEO optimization, additionally pay attention to:
- Use questions and answers (FAQ format) for shorter and specific answers.
- Structuring content to respond to “who”, “what”, “how”, “why”, and “when”.
- Adapting language for AI comprehension – using natural and colloquial language.
- Structured data tags (Schema markup), especially for reviews, products, articles, and FAQs.
Optimized content has a significantly higher chance of being displayed in search engines, Google AI Overviews , or in response in AI chats.
4. Promote content across multiple channels
Writing good content is not enough if no one knows it exists. It is necessary to actively promote the content in order to reach the target audience and drive traffic, clicks and conversions.
Channels that are effective for promoting affiliate content:
- Social networks (Facebook, LinkedIn, Pinterest, Instagram)
- Email marketing – sending newsletters with useful tips and recommendations
- SEO – A Long-Term Source of Organic Traffic
- Forums and communities – participate in discussions and share links where appropriate
- Collaborations with other bloggers and content creators – e.g. guest articles
By combining multiple traffic sources, you increase the chance of more conversions and less reliance on a single platform.
5. Sign up for affiliate programs and track the results
When you’re ready to promote products, sign up for affiliate programs relevant to your niche. There are large affiliate networks that connect you to dozens or hundreds of brands, as well as direct programs that come directly from manufacturers or service companies.
Criteria for choosing a good affiliate program:
- Commission amount (percentage or fixed amount)
- Duration of the cookie period (e.g. 7, 30, 90 days)
- Withdrawal conditions (minimum threshold, currencies, payment methods)
- Support and reputation of the program or network
When you get started, track the results through analytics tools. Measure clicks, conversions, bounce rates, dwell time and traffic source. This data is crucial for optimizing and improving efficiency.
