  We evaluate the Configurational Entropy (CE) for scalar mesons and for
$J^P=\frac{1}{2}^+$ baryons in a holographic approach, varying the dimension of
boundary theory operators and using the soft-wall dual model of QCD. We find
that hybrid and multiquark mesons are characterized by an increasingly large
CE. A similar behavior is observed for $J^P=\frac{1}{2}^+$ baryons, where the
CE of pentaquarks is larger than for three-quark baryons, for same radial
number. Configurational Entropy seems relevant in disentangling conventional
hadrons from exotica.
