Recent years I had come across more online earning opportunity and you tube is on them with more potential of earning money. Here it goes, you need to register a channel and have to link your videos with google monetization policies. You need to register for google adsense account as well. Once videos you upload reaches 10k LIKES your account will be activated and your videos are eligible for monetization where you need to fill out KYC docs and link your bank account. Your video should not violate several google policies like copying a video which is already in youtube or other video source online, copying a music etc. Easy make videos such as Photo videos & copy rights free music will help to get more likes and subscribers. Informational videos and self made live videos, viral videos making will capture more attention and audiences all around the world. The secret of making more likes & subscribers depends on your creativity and informations you deliver. Moreover, making a kids videos, cartoons scores more number of views online.
The Bottom line is you can earn well in youtube unless you wait patiently for your earning and your frequency in making videos. I too have a channel PREVIEW CLUBB but I cant make it to the mark coz I lack patience in waiting.
All the best for who have plan to try it out. Check out for new rules announced by youtube for monetizing videos.
