The verbs can be transitive or intransitive:

My nose smells (odors) badly because I have a cold.
The dinner smells bad because it is burnt.

In the senses you have used them in, they are copulative. A copulative verb creates an identity between the subject and what follows, in this case a predicate adjective. A few examples are "act", "feel", "look" and "seem". As Mister Macawber has pointed out, these verbs can be used non-copulatively.

Thank you for idea!

I've found that "smell" is "a linking verbs"

It is a linking verb sometimes, not always.

If you are talking about the action of detecting odors (like a bloodhound), then it's not a linking verb.
If you are talking about how you perceive the scent (the burned dinner smells bad, your new perfume smells good),

Now I see

Thank you

So, If I am talking about the action of detecting odors, can I use adverbs after verb?

Right.

And if the dog is smelling bad, it needs a bath.
