Building a modern rock project with Suno – looking for advice

Hi everyone!
I’m Siggi from Germany and I’m building my project Siggi & The Sparks.
I’ve just submitted my fourth single to Spotify and I’m trying to build a real audience instead of just uploading songs.
I’d love to hear from people who have been doing this longer:
What helped you grow the most?
Reddit?
YouTube?
TikTok?
Spotify playlists?
I’m here to learn and I’d appreciate any advice. 🤘
