24 days.
Just kidding.
Honestly, it’s kind of up to you. You could take this course, watch the ads module, and start running a campaign today. You’d start seeing followers / streams come in tomorrow. Or you could pitch one curator, get on the playlist of your dreams, and blow up immediately.
But I recommend giving yourself at least three months.
Growth can be hard. Your first playlist pitch will probably be ignored. Your first ad campaign will probably be your worst.
But your 10th pitch might garner a placement. Your next ad campaign might get more followers at a lower cost.
Like anything else, you’ll get better at this the more you do it. Or, put another way, you’ve got to keep doing it to get better.
So, yeah, 24 days
