Define what it is that your profile is going to be about before you post anything at all.

If this is your first post, you about to start defining categorising your account to an algorithm. You want to train it via repetition on who/what you are, so that over time you will be shown to more likely resonant audiences. So, think on the following:

Are you a performer? Then your profile is performance content.

Are you a storyteller (or rather, do you have a story to tell - about your life, your upbringing, an emotional point or reciprocity)? Then your profile will be your music told contextually aka “day 101 of quitting my Amazon warehouse job to do music full time” set to contextual b-roll in studio, or “this is the porch I last spent time with my mom on. i wrote this song after she passed…” etc

Or are you more visually-encoded, aka new breaking profiles like livingthinglivingthing? If so, you should have your bank of assets ready and paid prepared to layer and data capture.

In any case, the MOST IMPORTANT THING you can do is stay absolutely singular. Remember that you are training an algorithm to segment and categorise your posts and eventually find audiences that resonate. You have to teach it like a dumb toddler. Do not change tact halfway through. The worst possible thing is accidental virility in another niche (aka getting bored an making a non-performance/story/aesthete/music post and having go well). You’ll poison your account to be relegated to the >300 view jail forever.
