If you’ve been using KWFinder, or KeySearch, or Long Tail Pro, or KeywordRevealer, or [Insert Tool Name Here], you might have noticed a rather annoying problem these days – they don’t freaking work.
Let me explain. All of these tools, basically, use the Moz API to get Moz data such as Domain Authority, Page Authority, MozRank and MozTrust for the top 10 SERP results for a certain keyword. They all then use their own difficulty formula to calculate Keyword Difficulty, or Competitiveness, if you will. They have different interfaces and some are better at than others, but the main idea is the same.
Apart from other, less obvious problems when it comes to trusting these tools for their Keyword Difficulty estimations, there is one that is their biggest flaw and weakness – they base their estimates on someone else’s data, or in this, Moz.
