How do earn from youtube?

you don't.

As far as I know, it is difficult for most people to earn some money using YouTube.

But on the other hand, perhaps you can have a try if you are interestend in it. It is said that you can add some ads when you uploading videos. Of course, you can also upload the videos with your watermark, which can't help you make money but may be helpful to your websites or products.

When it comes to earning with YouTube, it is said that Google will allow webmasters to add their own AdSense codes into videos, which means you can make money with your AdSense account. Good luck!

I would recommend the guys that recommended me to here, my-data-team, they have all you need to learn everything about advertising on the web. The teach you how to write articles and bloggs, not to mention the loads of other jobs on the net.
Im not going to affiliate a link for you, but just give you my personal recommendation.
The youtube ads dont really get much response. Try craigslist and google as top places to get advertisement on the web. But your gonna have to find some affiliate links to get started.

while others earn on youtube by placing advertisement on it or you as a viewer can make money too. Yes, you heard it right other members here in mylot had proved it. Let's try this if it is really legit.

You will be paid through viewing youtube videos www.paid2youtube.com good luck!

hello ybong, somehow noticed about youtube having such ads in their videos but when i found out that feature is only allowed for the US citizens, i just thought about joining a site that pays by watching youtube videos. there were two sites that was referred to me by a mylot friend. i joined the first but unfortunately i got issues with the first one when they set their data, causing me too loose all except banner credits. i got refunded when i complained to Paypal, but then they removed my account saying that i pissed him off by not reading reminder of his darn message to the members.

You have to apply to YouTube's Partnership Program to get ads/banners put on your Youtube page that will provide you with ad revenue. You need to have very high page views to qualify for this. Go to YouTube.com/partners. Unless you have over a million views or over 1000 subscribers you probably won't be approved for this but you can always try again later when your videos are more poplular. You can, however, post videos that promote other programs you participate in like mylot and other sites that pay you for posting, clicking ads, your personal blog etc.
