  In the context of bottom-up AdS/QCD models, we discuss how the
configurational entropy can describe heavy non-$q\,\bar{q}$ states. Using the
non-quadratic softwall model, introduced to describe non-linear Regge
trajectories, we parametrize different multiquark and exotic meson structures
to describe $Z_c$, $\psi$, and $Z_b$ states as non-$q\,\bar{q}$ hadrons in
terms of stability. We found that $Z_c$ is better described as a hybrid meson
with one gluon tube, $\psi$ as hadrocharmonium, and $Z_b$ as hadronic molecule.
