In this paper we prove that any complete n-dimensional conformal gradient soliton with nonnegative Ricci tensor is either isometric to a direct product R x N^(n−1), or globally conformally equivalent to the Euclidean space R^n or to the round sphere S^n. In particular, we show that any complete, noncompact, gradient Yamabe-type soliton with positive Ricci tensor is rotationally symmetric, whenever the potential function is nonconstant
