Before your brand is able to monetize your YouTube channel there are some preliminary requirements that need to be taken into consideration. To be able to monetize your channel you will first need to have the following:
• 1,000 Subscribers
• 4,000 hours of Watch Time
• Follow all the YouTube policies and guidelines
• Have a Google Adsense account (or have your channel be linked to one)
While having the prior requirements are the first step to monetizing your channel, you then need to apply to the YouTube Partner Program. YouTube will then review your channel and assess whether your account is eligible for monetization (wait times do vary).
