What is Affiliate Marketing and how can you make money with it?

Affiliate Marketing: the ultimate guide to sell more (even while you sleep)

Today we’re going to talk about one of those strategies that sounds like digital black magic but is actually one of the most powerful and accessible tools to grow a business: affiliate marketing.

Imagine it for a second. You have a fantastic product or service. Now, imagine you have a team of enthusiastic salespeople all over the world, recommending what you do to their audiences with enormous credibility. Best of all, you only pay them when they make a sale. It’s not a dream; it’s not science fiction. It is, in essence, affiliate marketing.

Whether you are an executive looking for new revenue streams for your SME, the director of a multinational that is landing in Madrid, or an entrepreneur, eager to monetise your influence, this article is for you. We’re going to demystify this concept and give you a clear roadmap, in language that, I promise, won’t make you yawn. Let’s get to it!

So, what exactly is affiliate marketing? Debunking the myth.

Let’s start at the beginning. Affiliate marketing is a performance-based marketing model. Simply put, a company (the “merchant” or “advertiser”) pays a commission to an external person or company (the “affiliate”) for generating traffic, leads or, more commonly, sales through their marketing efforts.

To put it simply: you recommend something → someone buys because of you → you get paid.

Think of it as the Digital Cupid of business. The affiliate connects someone who has a need (a potential customer) with the company that has the solution (your product or service), and if that connection ends in a “wedding” (a sale), the affiliate gets a commission for playing matchmaker.

This ecosystem has four main players:

The Merchant (or Brand): This is the creator or owner. The company that has a product or service to sell. It can be anything from an online course to software, physical products or, why not, flexible workspaces.
The Affiliate (or Publisher): This is the promoter. It can be a blogger, an influencer on social networks, the owner of a YouTube channel, a podcaster, a simple housewife who wants to earn extra money… Someone with an audience or community that trusts their recommendations. The affiliate promotes the merchant’s products using a unique and personalised link.
The Customer: The person who clicks on the affiliate’s link and makes the purchase. The ultimate goal of all this gear.
The Affiliate Network (Optional but common): These are the platforms that act as intermediaries, such as Amazon Associates, Awin, Hotmart or ClickBank. They offer the technology to track clicks and sales, manage payments and connect merchants with thousands of potential affiliates. It’s like a big marketplace where both sides meet.

The beauty of this model is that it’s a win-win-win. The company gets sales with minimal risk (they only pay for results), the affiliate monetises their audience without having to create a product of their own, and the customer discovers useful products through a trusted source.

Why is affiliate marketing so popular?

Because people don’t need to:

Create their own product
Own inventory
Do customer service
Invest a lot of money up front

They just need

An audience (even a small but well segmented one)
Good content
A strategy

And the best part: it works for all kinds of industries. From technology, health, beauty, education, to… yes, cowoking! They can also be included under this business model.

The steps to conquer the world of affiliate marketing

Now that we know the theory, let’s put it into practice. How do you set this up? Whether you want to be an affiliate or plan to set up your own programme, the basics are crucial. Here’s the step-by-step roadmap.

Step 1: Choose your side and niche market

The first thing is to decide whether you want to be the hero (the affiliate) or the conductor (the company creating the programme).

If you want to be an affiliate: Don’t try to sell everything to everyone! The secret to success is specialisation. Are you passionate about financial technology? Sustainable design? Productivity for freelancers? Choose a niche that you know and are passionate about. Your authenticity will be your best sales weapon. A niche audience trusts an expert more than a “jack-of-all-trades”.
If you want to create an affiliate programme: Define which products or services from your catalogue are the most attractive to promote. Do they have a good margin? Do they solve a clear problem? These will be the star products of your programme.

Step 2: Build your platform and your audience

No one is going to click on your links if you have no one to listen to you. An affiliate without an audience is like a singer without a stage. You need a platform where you can consistently deliver value. Some options are:

A Blog or Website: It’s the king for a reason. It gives you total control and is perfect for SEO. You can write product reviews, comparisons, tutorials…
A YouTube Channel: Video is incredibly persuasive. You can do unboxing, product demonstrations or hands-on tutorials.
Social Networks (Instagram, TikTok, LinkedIn): Ideal for visual or professional niches. Ephemeral and direct content works very well but requires consistency.
A Podcast: If voice is your thing, a podcast allows you to create a very intimate connection with your audience.

The key here is to CREATE VALUABLE CONTENT. Don’t just post links. Teach, inform, entertain. Solve your audience’s problems and, naturally, recommend the tools (your affiliate products) that will help them get there.

Step 3: Find the perfect affiliate programmes

Once you have your niche and your platform, it’s time to find “dance partners”. Where do you look for companies that offer affiliate marketing programmes?

Great affiliate networks: Platforms like Awin, Rakuten Advertising, ShareASale or Amazon Associates are a great place to start. They have thousands of brands from all industries.
Direct search: Many companies run their own programmes. Try Googling “[Brand name] + affiliate programme” or look for an “Affiliates” or “Partners” link in the footer of their website.
Your own experience: What tools or services do you already use and love? Chances are they have an affiliate programme. Promoting something you already believe in is the most authentic and effective way to do this.

When choosing, look at: the quality of the product (never junk promotions!), the commission percentage, and the cookie duration (the time you have for someone to buy after clicking on your link and you still receive the commission).

Step 4: Integrate links with strategy and subtlety

You’ve got the content and the links. Now, how do you link them together without making it look like a 3 a.m. telemarketing commercial?

Within the text: Mention the product naturally in an article. For example: “To optimise my workflow, I use [tool with affiliate link], which saves me hours a week”.
In-depth reviews and analysis: Write an article or make a video dedicated exclusively to analyse a product. Be honest, mention the pros and cons. People value transparency.
Resource Pages: Create a page on your website with a list of all the tools, books and resources you recommend. It’s a useful reference place for your audience.
Banners: These are more traditional and less effective, but they can work if placed in strategic places on your website without being intrusive.

Important: Transparency is the law. You should always inform your audience that your links are affiliate links and that you may receive a commission. Not only is this good practice but, in many countries, it is a legal requirement. Trust is everything.

Step 5: Measure, analyse and optimise (the infinite loop of success)

Affiliate marketing is not “set it and forget it”. You must act like a data scientist.

Monitor your clicks: Which links get the most attention?
Analyse your conversions: Which of those clicks convert into sales?
Experiment: Try different types of content, different products and different calls to action.

Affiliate platforms will give you dashboards with all this information. Use it to understand what resonates with your audience and what does not. Then, do more of what work and adjust or discard what doesn’t.

What if I am the company? Creating your own affiliate programme

So far, we’ve talked about it from the affiliate perspective. But what if you are the manager of an SME or a growing multinational? Creating your own affiliate marketing programme can be a spectacularly profitable customer acquisition channel.

It’s essentially outsourcing your marketing to an army of motivated professionals who only get paid if they succeed. For a company looking to establish itself in Madrid, like the ones that rely on Ibercenter, it’s a way to gain traction in the local and international market without an exorbitant initial investment in advertising.

The steps are similar:

Define clear terms and conditions: what commission will you offer; will it be a percentage of the sale or a fixed amount; what will be the duration of the cookie?
Choose a technology: You can use an affiliate network (which gives you access to their publisher base but charges a commission) or specialised software to manage your own programme (more control but requires more work to recruit).
Create materials for your affiliates: Give them banners, email templates, suggested texts… Make it easy for them to promote you.
Recruit the right affiliates: Find influencers and content creators in your niche and introduce them to your programme.

The ecosystem of success: the role of a professional environment

At this point, you will realise that, although accessible, affiliate marketing requires strategy, focus and professionalism. And this is where Ibercenter sees a fundamental connection.

For such a powerful digital strategy to work, you need maximum focus. You can’t be worrying about whether your internet connection is down, whether you’ll have a suitable space to shoot your next video or whether the image you project in a meeting with a potential affiliate partner is the right one.

For an entrepreneur: Imagine running your blog and YouTube channel from one of our offices in Gran Via. An inspiring space, with a guaranteed high-speed internet connection and surrounded by other professionals. If you need to record an interview for your podcast or meet with a brand, our meeting rooms are perfectly equipped for everything to be professional.
For an executive: While your team focuses on closing strategic deals, you can implement an affiliate marketing programme to diversify your SME’s sales channels. At our Azca or Velázquez locations, you have the premium infrastructure and corporate environment that frees you from the day-to-day logistics. You focus on strategy, not building management.

You get the peace of mind of knowing that all the infrastructure is taken care of. This frees up resources and mental energy for your marketing team to launch rapid growth initiatives, such as a powerful affiliate marketing programme to conquer the Spanish market.
