How do channels go viral this fast?

Hello!
Long time reader first time poster. I want to know how channels such as
Dime- https://youtube.com/channel/UCpyoYVlp67N16Lg1_N4VnVw
Hoopsflix- https://youtube.com/c/HoopFlix

go viral insanely quick? Their quality is definitely very good but how do they get in the algorithm so fast and gain insane traction on not many videos uploaded. If anyone knows it would be greatly appreciated. Any paid methods are fine too just wondering how they do it.

If I look closely it's original and edited content so it's normal that the ranking is strong...

Their content is original and quality is very good. Have you noticed their content length? On an average the videos are over 10 minutes long. So the users are watching the content for more time and it is telling the algo that the content is popular. In turn the algo promotes / suggests this content to other users with similar interest.

This is how You Tube algorithm works.

The key here is to create good quality, original and long form content.

If content is good and editing is also on the spot, it will surely rank.

if your content has quality so make ads in google it will surely help to get viral

This is usually not their first channel. They have already learn from so many mistakes in previous failed channels.
