It’s comprised of several things:
Sales, Average feedback rating, involvement in forums and the fiverr community, delivered on time, social media and marketing outside of fiverr, etc.
I think for you brady_bear start by just going through the level 1 seller, level 2 seller and top seller levels. By doing that you’ll know that you are adhering to fiverrs best practices and experiencing growth in your business. With you already starting to promote on social media sites, it will give you some great momentum to possibly catapult you into featured status.
I wish you much success!
