We have all heard of Google Traits, the web site that analyzes the recognition of prime search queries throughout varied areas and languages. Effectively, this isn’t that.

A at the moment trending search is a time period or phrase that all of a sudden will increase in reputation. As folks flock to Google to ask the identical query, the question could present up as a suggestion, even when it hasn’t gained reputation in the long term.
