social engineering, PR stunts,
going viral is no different then solving a math problem, there is a formula to hack peoples minds because emotions are predictable. pr stunts have been used for hundreds of years for a reason
google more into pr stunts, and check out memes that do this. like how a video of a veteran coming home to there dog will get 1 million likes, understand why. it reaches into a persons mind and hooks a certain emotion
same reason why drama, outrage, will get more attention then something boring
read into psychology and keep practicing
