Your best bet is to look for them together.

"Our research strengthens the argument that methane and oxygen together, or methane and ozone together, are still strong signatures of life," said Shawn Domagal-Goldman of NASA's Goddard Space Flight Center in Greenbelt, Maryland and the study's lead author. "We tried really, really hard to make false-positive signals for life, and we did find some, but only for oxygen, ozone, or methane by themselves."

Have any of these tips worked?

My diving rod works about as well for finding alien life.
