You are a single person and desperately looking for a partner. You come across many members of opposite gender, get attracted to them by instinct but you don't find something special in most of them to take relation to next steps. Why we don't feel "really going mad" about everybody we get initially attracted to?
Scientists agree that what truly bonds two members of opposite genders is very complex to describe apart of natural and plain physical attraction. They call it as secondary attraction.

Indeed, it's not just look or appearance required to stay in (long term) romantic or committed relationship. There's something beyond physical qualities we look into our potential partner(s). How the other person looks necessary should not match with its true nature.
During initial interactions, we unconsciously monitor behavior and reactions of other person in different situations and circumstances. In fact, we give each other various opportunities for same. More we interact, better we understand each other (apart of attraction). It's like initiating a dance step and waiting for a person on an opposite side to make move accordingly.
We always convey personal traits, attitude, approach, qualities, strengths, and weaknesses and ultimately mutual compatibility through body language (nonverbally) only that's why attraction based upon character lasts longer and healthier.
