We use the premier keyword data provider on the Internet, Ahrefs. This tool has the largest and most consistently updated database of keywords. It’s an essential tool in our work.
Generally speaking, keyword data is going to be less than 30 days old. There are millions and millions of searches out there, it’s a chore to obtain all of the data and categorize it effectively. That means keyword data does not come in uniformly, some may have been updated yesterday, while others 10 days ago.
