Affiliate Marketing — Explanation & Step-by-Step Roadmap

What is Affiliate Marketing?

Affiliate marketing is a performance-based business model where an affiliate promotes another company's product or service and earns a commission when a desired action (sale, lead, sign-up) occurs through their unique referral link.

The short version

Beginner-Friendly Step-by-Step Roadmap

1. Choose Your Niche

Pick something you enjoy and can talk about consistently. Narrow down — specific beats general (e.g., "home workouts for busy parents" instead of "fitness").

2. Find Affiliate Programs

Join networks or vendor programs. Compare commission type (sale, lead, recurring) and cookie length.

3. Create Valuable Content

Focus on helpful content: reviews, tutorials, comparisons, and "best of" lists. Build trust first.

4. Add Affiliate Links & Be Transparent

Insert links naturally. Always disclose affiliate relationships to retain trust and comply with rules.

5. Drive Traffic & Optimize

Use SEO, social media, and email. Track clicks, conversion rates, and double down on what works.
