  For conformal field theories, it is shown how the Ward identity corresponding
to dilatation invariance arises in a Wilsonian setting. In so doing, several
points which are opaque in textbook treatments are clarified. Exploiting the
fact that the Exact Renormalization Group furnishes a representation of the
conformal algebra allows dilatation invariance to be stated directly as a
property of the action, despite the presence of a regulator. This obviates the
need for formal statements that conformal invariance is recovered once the
regulator is removed. Furthermore, the proper subset of conformal primary
fields for which the Ward identity holds is identified for all
dimensionalities.
