Ask Is it true that how a post performs in the first 48 hours decides whether it reaches a wider audience?

[Brajet]

Most social media platforms watch how people react to a post in its first hours, things like likes, comments, and shares all count. If that early activity looks strong, the platform usually pushes the post to more people outside its current followers. If it gets little reaction at first, it tends to fade quietly without much reach. Does that early window really decide the entire fate of a post, or can good content still find an audience later?
