  The mock Alexander polynomial is an extension of the classical Alexander
polynomial, defined and studied for (virtual) knots and knotoids by the second
and third authors. In this paper we consider the mock Alexander polynomial for
generalizations of knotoids. We prove a conjecture on the mock Alexander
polynomial for knotoids, which generalizes to uni-linkoids. Afterwards we give
constructions for canonical invariants of linkoids derived from the mock
Alexander polynomial, using the formalism of generalized knotoids due to Adams
et al.
