YouTube has become an attractive platform for earning extra cash or even as a main source of income.
But contrary to popular belief, YouTube stars don't only earn money from AdSense available on their channels.
American-born YouTube star Evan Edinger recently revealed to BBC the other sources of income for YouTubers in addition to AdSense.
Regular YouTube watchers may notice a link on YouTuber's bio or description box. Dubbed affiliate links, it contains a specific URL with the affiliate's ID or username.
When viewers buy something from a website after clicking on the affiliate link, the YouTube channel will most likely receive a share of the price.
Edinger said the system not only allowed YouTube stars to promote something they liked, but it also gave them 5 to 20 per cent revenue on products.
Those wanting to help their favourite YouTuber may consider buying merchandise from them.
Edinger revealed that items such as posters and wristbands, among others, are among the sources of income for YouTube celebs.
Edinger mentioned that brand deals are the biggest sources of income for YouTube stars.
Usually, companies would hire these YouTubers to make videos about their products.
"It can pay 12 times your monthly AdSense [revenue]. That sounds unreal, but it is true," said Edinger.
