I'm really not sure! I was going to say good chemistry, but chemistry can apply to friendships as well, and people who make good friends don't necessarily make good romantic partners (Korra and Mako from TLOK come to mind). Maybe, ships deal more with emotional responses than logical thinking. It's possible to analyze a ship and point out why it's good as you would analyze a character (which I'd love to do with Monochrome!), but I feel like strong gut reactions are also important when it comes to finding a good or popular ship. After all, Yang and Blake hardly interacted in volume 1 and yet people still shipped Bumblebee like crazy. But still, I don't have a concrete answer.

And now I'm thinking that it would be cool for two characters in RWBY to have a relationship that doesn't work out and they become friends instead. I nominate Weiss and Neptune, or maybe Sun and Blake.
