The two main factors are: A breathable atmosphere and liquid water. The planet also should be in the "Goldilocks zone" or Habitable zone. Without a breathable atmosphere like ours, there would be no life. That is also a reason why NASA haven't found anything or life in Mars. Mars is full of carbon dioxide (CO2).
