What is Affiliate Marketing & How Does it Work?

Affiliate marketing has become one of the most powerful, data-driven ways for brands to reach customers and drive measurable growth. But how does it actually work and why are more marketers investing in it than ever before? 

In this guide, we’ll unpack the fundamentals of affiliate marketing, explore the key players involved, and show you how Rakuten Advertising helps advertisers and publishers create meaningful, performance-driven partnerships. 

What Is Affiliate Marketing?

Affiliate marketing is a performance-based partnership between a brand and a publisher (or “affiliate”). 

Affiliates promote a brand’s products or services through content, links, or offers. When a customer makes a purchase or completes a desired action through that affiliate’s link, the affiliate earns a commission. 

It’s a win-win model: 

• Brands gain incremental sales and visibility. 

• Affiliates earn revenue for driving measurable results. 

• Affiliate and partner marketing connects brands and audiences through trusted partnerships, and performance data ensures every click and conversion counts. 

The Key Players in Affiliate & Partner Marketing

Every successful affiliate program involves four main participants: 

Advertiser: The business selling a product or service. Example: a retailer, travel provider, or subscription service. 

Affiliate (Partner): The partner or publisher promoting the brand, such as a content creator, media site, or loyalty platform. 

Consumer: The customer who discovers and buys through the affiliate’s link. 

Affiliate Network: The technology and infrastructure that connect advertisers and partners, track performance, and manage payments. Rakuten Advertising, for example, is the leading global affiliate network which uses rich data and AI to connect advertisers, publishers, and audiences.  

At Rakuten Advertising, we bring these groups together.
