We consider the problem of computing the overlaps between the Bethe states ofthe XXZ spin-1/2 chain and generic states. We derive recursive formulas for theoverlaps between some simple product states and off-shell Bethe states withinthe framework of the Algebraic Bethe Ansatz. These recursive formulas can beused to prove in a simple and straightforward way the recently-obtained resultsfor the overlaps of the Bethe states with the N\'eel state, the dimer state,and the \textit{q}-deformed dimer state. However, these recursive formulas arederived for a broader class of states and represent a concrete starting pointfor the computation of rather general overlaps. Our approach can be easilyextended to other one-dimensional Bethe Ansatz integrable models.
