We show that exclusive double-diffractive Higgs production, pp\to p+H+p, followed by the H\to b\bar {b} decay, could play an important role in identifying a `light' Higgs boson at the LHC, provided that the forward outgoing protons are tagged. We predict the cross sections for the signal and for all possible b\bar {b} backgrounds.
