Starting a YouTube channel is a powerful way to build a personal brand and earn money online. In Nigeria, popular niches include tech reviews, comedy skits, educational content, and lifestyle vlogs. Begin by identifying your target audience and creating valuable, engaging content tailored to them. Invest in basic equipment like a good smartphone, tripod, and microphone for quality production. Once you reach 1,000 subscribers and 4,000 watch hours, you can apply for monetization through Google AdSense. Additionally, explore other revenue streams like brand sponsorships, affiliate marketing, and selling merchandise. Consistency, creativity, and audience engagement are the keys to success.
