✔ Ads
This is the easiest and most practical way to monetize videos on YouTube. Anyone can do it, so this doesn't depend on your content. It only depends on your traffic, because they are always tied to the number of views. The more clicks your users make in the ads, or see the 30 seconds of the full announcement, the more commissions you will receive.
✔ Brands
This is where you can start, to be an influencer. Many brands of all kinds of products, they like to advertise on YouTube. These exchange products for advertising, as well as products plus Commission for publicity. Long ago I saw that a Japanese store sent clothes to a Youtuber, all this for him to advertise his store. For girls This is great because they can get a lot of free things. Remember that the brand will depend on the content you have in your videos.
✔ Events
These are excellent at the time of wanting, to strengthen your followers. You can organize events in your city, where you sell tickets for this. Example if your channel is of makeup, you can organize a forum type course, on the automake. The events I recommend doing, when you really feel that you are very influential. Well, you need people to be interested in paying to see you. In this event you can put a lot of things on sale, to also earn more money. Another great idea is that before the event you can make a contest where Rifes a good prize in collaboration with a brand. One of the requirements to participate, can be to buy an entry for your event, because there will be the draw and will be awarded the prize.
