  We consider holographic superconductors in a broad class of massive gravity
backgrounds. These theories provide a holographic description of a
superconductor with broken translational symmetry. Such models exhibit a rich
phase structure: depending on the values of the temperature and the disorder
strength the boundary system can be in superconducting, normal metallic or
normal pseudoinsulating phases. Furthermore the system supports interesting
collective excitation of the charge carriers, which appears in the normal
phase, persists in the superconducting phase, but eventually gets destroyed by
the superconducting condensate. We also show the possibility of building a
phase diagram of a system with the superconducting phase occupying a
dome-shaped region on the temperature-disorder plane.
