Right Keywords Tool
 

I have worked on three keyword tools for keyword research that are Semrush, Ahref and Moz but found different keywords difficulty for one keyword. For example, if a keyword has zero keyword difficulty for one phase and for the same phrase Semrush and Moz has 60 or more keywords difficulty. How can we do right decision ?
