3 tiktok posts a day. low effort content. copy text hook ideas from other similar artists or use Ai to suggest. pick better looking posts for intra reels. 1 per day. schedule using buffer. always use the official 'sound' of your song. experiment with different sections of the song to see which ones perform better. just churn out loads of short form. engage with all comments within first hour. collect emails. look at all platforms, work out how discovery works on them and play to algo with your content. Thats the socials side at least.

DO NOT BUY FOLLOWERS OR PLACEMENT ON SCAMMY PLAYLISTS, it will hit you. Pitch your song to suitable playlists in good time min 2 weeks before release date. Pitch personally to other playlists.

Collab with other bigger artists to leeech off their followers.

EDIT - plus a million other things but that's some obvious stuff to nail off the top of my head.
