Actually you could look for temperatures around 255K, since that's Global equilibrium temperature for Earth:

Atmosphere warms Earth to 288K

I think over the next years we will find many exoplanets who are very earth-like. There should be thousands alone in our galaxy.
But, I'm not sure whether that brings us a closer to find life. It may hard, if there is life, but no higher lifeforms or civilizations, to explore it from so far away.

Undertakings like Kepler mainly do probabilities. It gets us closer to finding life in the sense that it narrows our search, and gives us a better idea of where to go once we have probes to explore the planets on location.

If you're talking about outright confirmation of life, right now, SETI has more of a chance, but that's just because confirmation really isn't what telescopic observation is used for.
It is said that an eastern monarch once charged his wise men to create a unique gift for him. He wished for a possession that would bring happiness in sad times and sadness in happy times. A while later the wise men returned and presented the monarch with a ring on which was written the words, "This too shall pass away."
