Can decent keyword research be done without having to pay any money for the premium membership to the well know keyword tools? I usually try brainstorming then check those keywords in google keyword planner and other free tools available. But some paid tools seem to provide very different stat. For example i had a keyword which showed no search volume in google keyword planner but one of the paid tool showed like 1000+ search volume. I don't know the tool used because i got the data from another source. And also the paid version gave many other relevant keywords which i didn't find in keyword planner or Ubersuggest or even kwfinder.
