  We present a comprehensive analysis of the spacelike nucleon electromagnetic
form factors and their flavor decomposition within the framework of light-front
holographic QCD. We show that the inclusion of the higher Fock components $\ket
{qqqq\bar{q}}$ has a significant effect on the spin-flip elastic Pauli form
factor and almost zero effect on the spin-conserving Dirac form factor. We
present light-front holographic QCD results for the proton and neutron form
factors at any momentum transfer range, including asymptotic predictions, and
show that our results agree with the available experimental data with high
accuracy. In order to correctly describe the Pauli form factor we need an
admixture of a five quark state of about 30$\%$ in the proton and about 40$\%$
in the neutron. We also extract the nucleon charge and magnetic radii and
perform a flavor decomposition of the nucleon electromagnetic form factors. The
free parameters needed to describe the experimental nucleon form factors are
very few: two parameters for the probabilities of higher Fock states for the
spin-flip form factor and a phenomenological parameter $r$, required to account
for possible SU(6) spin-flavor symmetry breaking effects in the neutron,
whereas the Pauli form factors are normalized to the experimental values of the
anomalous magnetic moments. The covariant spin structure for the Dirac and
Pauli nucleon form factors prescribed by AdS$_5$ semiclassical gravity
incorporates the correct twist scaling behavior from hard scattering and also
leads to vector dominance at low energy.
