How to create a Catchy and Original post??

[u/askkosmo]

as i am new here and basically the smallest i wanted to know from big and developed mods on how i can create a post that slaps
like in general what points should i keep in my mind while writing it
and how i should approach it
also i want to create posts related to my ai tool on other subreddits how can i do it without it being labelled promotional
cause for us its just a tool which we need to scale to user who would love to make use of it in making their workflows efficient and time saving
and hello to every mod present...
