FAQ

Questions about free keyword research tool

Type a seed keyword in the box at the top of this page and run it. You get 20 related keywords with their monthly search volume, difficulty and cost per click, sorted from the most searched.

From DataForSEO Labs, which takes it from Google Ads data for the United States in English. The number is the average monthly searches over the last 12 months.

DataForSEO's estimate, from 0 to 100, of how hard it is to reach the top 10 for the keyword, based on the link strength of the pages that rank now. Lower is easier.

What most searchers want: informational (learn something), navigational (reach a site), commercial (compare options) or transactional (buy or sign up). It comes from DataForSEO's classifier.

Google Ads groups close variants, such as a plural and a singular, and reports one volume for the group. DataForSEO passes that number on for each variant.
