The maximum (or minimum) on the plot corresponds to the stoichiometry of the two species if sufficiently high concentrations are used. The plot also provides insight to understand the equilibrium constant (Keq) of complex formation. A greater curvature leads to a more evenly distributed equilibrium, while a more triangle-shaped plot signifies a large Keq. Further, after determining the equilibrium constant, we can determine what complexes (ratio of A and B) are present in solution. In addition, the peak of the Job Plot corresponds to the mole fraction of ligands bound to a molecule, which is important for studying ligand field theory. An early work of I. Ostromisslensky describes essentially this approach.
