The noun verbiage, meaning an excess of words, has negative connotations. When one refers to the verbiage of a piece of text, this implies that the text is wordy, impenetrable, or pretentious. The word is not traditionally synonymous with neutral words such as text, words, wording, or content, though it is sometimes used this way.
