Digital marketing and affiliate marketing are distinct concepts within the realm of online promotion, though they often intersect.

**Digital Marketing**: This is a broad term encompassing all marketing efforts that use the internet or electronic devices. It includes various strategies such as search engine optimization (SEO), social media marketing, email marketing, content marketing, pay-per-click (PPC) advertising, and more. The primary goal is to reach potential customers through digital channels, enhance brand visibility, and drive sales or engagement. Digital marketers create and manage comprehensive campaigns that target audiences based on data and analytics, employing a mix of paid and organic tactics.

**Affiliate Marketing**: This is a subset of digital marketing where a business rewards affiliates (partners) for driving traffic or sales to their website through the affiliate’s marketing efforts. Affiliates earn a commission for each sale or action generated through their referral links. This model is performance-based, meaning affiliates are only paid when their marketing efforts result in a desired action, such as a sale or lead. It leverages the reach of individual marketers or influencers, allowing businesses to tap into diverse audiences without upfront advertising costs.

In summary, while digital marketing encompasses all online marketing activities, affiliate marketing specifically focuses on performance-based partnerships where affiliates promote products or services in exchange for commissions.
