  We present a universal interpretation for a class of conformal extended
standard models including Higgs portal interactions realized in low-energy
effective theories. The scale generation mechanism in this class (scalegenesis)
arises along the (nearly) conformal/flat direction for the scale symmetry
breaking, where the electroweak-symmetry breaking structure is achieved in a
similar way to the standard model's. A dynamical origin for the Higgs portal
coupling can provide the discriminator for the low-energy ``universality
class'', to be probed in forthcoming collider experiments.
