Key Takeaways

Affiliate marketing lets you earn by recommending proven products instead of building your own.

Passive income comes from evergreen content, email follow‑ups, and recurring programs.

Focus on one niche, one offer type, and one traffic source until it works.

Build an email list early to turn one click into many offers over time.

Track CTR, EPC, and opt‑in rates so you fix the right bottleneck first.
