To monetize your YouTube videos on mobile, you will need to meet certain eligibility criteria and then follow the steps below:
1) Meet YouTube's Partner Program requirements: In order to monetize your videos, you must first meet the eligibility criteria for YouTube's Partner Program, which includes having at least 1,000 subscribers and 4,000 watch hours in the last 12 months, among other criteria.
2) Enable monetization: Once you meet the eligibility criteria, you can enable monetization for your videos by going to your YouTube Studio app on your mobile device, clicking on the "Monetization" tab, and following the steps to enable ads on your videos.
3) Choose ad formats: After enabling monetization, you can choose which ad formats you want to display on your videos, such as pre-roll ads, mid-roll ads, and overlay ads.
4) Review and monetize videos: Once you've enabled monetization and chosen your ad formats, you can review your videos and monetize them individually by going to the "Videos" tab in your YouTube Studio app and selecting the videos you want to monetize.
5) Monitor earnings: You can track your earnings in the "Revenue" tab of your YouTube Studio app, where you can see your estimated earnings and payment history.
