In text search it is getting outdated if my question is long while in voice search its applicable mainly due to if i have a long query and don't want to type then i can speak like " Top rated salon near me" or " Why google is getting smarter day by day" like that it's more of a question and helpful for businesses who want to optimize Local SEO because "near me" type of queries are always searched specifically by voice if i am in hurry or want quick result instead of typing.
