Tags

Add as many tags you can. Because often people use YouTube’s search bar to find their favourite keywords. So don’t miss any related tags that may help them to find what they are looking for. Related tags thus increases your number of audiences. You know the more audience the more hits on your video and the more money from Adsense.

Description

After tags , description will help you to earn maximum from YouTube. Description should be pointed. You should add all the information needed to explain about the video so visitors will be curious to watching the videos. You can also add your website URL on the top of description. This will help you to drive more visitors from YouTube.

Thumbnails

Thumbnails is the small sized image which will glorify your video. How do they earn money from YouTube? They choose thumbnails carefully that will attract the visitors.

Be the first to Upload it

Usually the first one uploaded gets much more views than the later ones. So if you find out any idea don’t hesitate to upload it to YouTube before its too late.

Affiliate Program

This is another trick that many tried and they never failed. Impress your visitor to buy a product and add your affiliate link on the end of the video and be sure that you will be paid if someone follow your link and buys the product.

At the last of my post, I want to suggest you to choose a niche and have proper research on it. Because without having proper and vast knowledge on the specific area you can’t get success in the long run.
