In terms of pricing, KWfinder likely offers the greatest value to users. Top end keyword research tools and SEO platforms - like SEMrush & Ahrefs - are going to cost substantially more. KWfinder does a fantastic job of providing a quick solution when researching keywords and its dashboard is extremely simple to use for beginners. KWfinder does, however, rely on data from outside sources like Moz, which means Moz Pro users can access a lot of the information already.
