Example
Sanjay created a YouTube video reviewing the “Raspberry Pi 4” and included his Amazon affiliate link, earning ₹4,500 in commissions over two weeks.
Tips
- Focus on products you’ve used personally; authenticity drives clicks.
- Embed links in blog posts, Instagram stories, or WhatsApp groups.
- Track performance using Google Analytics and affiliate dashboards.
Warning
Excessive affiliate links can violate platform policies—keep the ratio of content to links balanced (e.g., 1 link per 300 words).
7. Participating in Online Hackathons
Many hackathons offer cash prizes, mentorship, and exposure without any entry fee.
Where to look
Platforms such as Devpost, HackerEarth, and TEDx publish free‑entry events.
