YouTube is the most successful video sharing platform. Per day millions of video unloaded in youtube. Also some of there uploader are fully professional. Now question how a person makes money from youtube video.
Actually there are two way to earn from youtube video. One of the way is youtube monetization program and other way is affiliate marketing.
For original content adsense allow a video uploader to run ads on their video. A percent of the income takes youtube and other portion takes video uploader. Currently a channel need at least 4000 hours watch time and 1000 follower to apply for monetization. Also video quality should be better to run ads. If any viewers click on add then the channel owner earns money. These days earning from youtube becomes very difficult.
Another way to earn money from youtube is affiliate marketing . In this case a video owner makes products review video and put an affiliate link in the description box. If anyone use that link to buy a product, he get some commission.
I prefer to choose affiliate program than adsense. If youtube approve adsense application, that will be a bonus income. Good bye today.
