This article considers the structure and properties of δ-Novikov algebras, a generalization of Novikov algebras characterized by a scalar parameter δ. It looks like δ-Novikov algebras have a richer structure than Novikov algebras. So, unlike Novikov algebras, they have non-commutative simple finite-dimensional algebras for δ=-1. Additionally, we introduce δ-Novikov--Poisson algebras, extending several theorems from the classical Novikov--Poisson algebras. Specifically, we consider the commutator structure [a, b] = a ∘ b - b ∘ a of δ-Novikov algebras, proving that when δ≠ 1, these algebras are metabelian Lie-admissible. Moreover, we prove that every metabelian Lie algebra can be embedded into a suitable δ-Novikov algebra with respect to the commutator product. We further consider the construction of δ-Poisson and transposed δ-Poisson algebras through δ-derivations on the commutative associative algebras. Finally, we analyze the operad associated with the variety of δ-Novikov algebras, proving that it is not Koszul for any value of δ. This result extends known results for the Novikov operad (δ=1) and the bicommutative operad (δ=0).
