Affiliate marketing is a passive income opportunity that involves promoting other people's products and earning a commission on sales. It is a great option for Nigerians because many international companies like Amazon, Jumia, and Konga have affiliate programs. To succeed, start by selecting a profitable niche, such as tech gadgets or health products. Build a platform for promotion—this could be a blog, YouTube channel, or even social media accounts. Use strategies like content marketing, email lists, and SEO to drive traffic. Remember, consistency is key. While affiliate marketing takes time to build, it can generate significant income once established.
