From what I've researched, it's social media (which we've been doing), the SEO's you use for your product, the quality of photography (including finding your unique way of photography and having multiple views. If it's original artwork, show pictures of process), how active you are (if you're posting new things and updating things consistently), the depth of product descriptions, and being part of a team. (I heard the more traffic you get, the more likely you're to show up. I don't know how true that is.)
