“To verb” is to make a verb out of something else, typically a noun. Lots of common words are (or appear to be) verbed nouns (even though many are nouned verbs!), so the verb “to verb” tends to be used only with obvious neoplasms.
“To verbify” is simply to use many verbs (cf. “speechify”).
“Verbification” is the noun form of “verbify”, as in “his verbification was delightful”.
“Verbifying” is an alternative to “verbification”, as in “his verbifying delighted the audience”.
A verb constructed by verbing a nouned verb is of course a “reverb”. Repeating the process (which is orthographically invisible except to the trained professional) is known as reverberation.
