I have a 75k follower Instagram account in the fitness niche, and I'm listed on most major markets. I still get very little of my income from shoutouts, with only the occasional DM for a purchase or sale from a shoutout marketplace. Right now I'm mostly focused on selling personal training through my Instagram account, so I haven't been able to focus on finding brands to sell shoutouts to and expand that part of the the business. How can I fix the abysmal amount of shoutouts I'm selling? I have 75k followers but only grossing $30/mo in shoutouts. How can I find people who want to buy shoutouts?
