There are several ways to make money online with YouTube. Here are some of the most popular ones:

1. AdSense: You can make money by allowing YouTube to display ads on your videos. This is done through Google AdSense, and you’ll earn a portion of the ad revenue each time someone clicks on an ad.
2. Affiliate marketing: You can promote products or services in your videos and include affiliate links in the description. When someone clicks on your link and makes a purchase, you’ll earn a commission.
3. Brand deals/sponsorships: If you have a large following, brands may pay you to feature their products in your videos or to promote their brand in some other way.
4. Merchandise: You can sell your own merchandise, such as T-shirts or mugs, through YouTube’s merch shelf feature.
5. Super Chat: If you have a live stream on YouTube, viewers can pay to have their comments highlighted, and you’ll earn a portion of the payment.
6. Fan funding: You can allow viewers to support your channel with monthly contributions through YouTube’s channel membership feature.

Keep in mind that making money on YouTube takes time and effort. You’ll need to consistently produce high-quality content that appeals to your target audience, and you’ll need to build a following before you start seeing significant revenue.
