Don’t worry, you haven’t done anything wrong.
When a brand sets up a campaign, they set requirements for the type of creators they want to work with on that specific campaign. Requirements might include age, location, and capabilities mentioned in your portfolio. Brands may also consider factors like followers, if you’re badged as a Pin Collective member, or your feed’s aesthetic.
If there aren’t any gigs for you at the moment, it might be that you don’t meet the requirements of any current gigs. It could also mean that none of the gigs visible to you on Pop Pays are currently accepting applications, and one might open up soon. Be sure to check back, new opportunities are popping up all the time.
