Hi,

Moz says that keyword difficulty score is based in domain authority and page authority of the competing 20 search results for a keyword. I wonder if it only takes those 2 values because, in that case, that score would not be representative enough for the difficulty. Does not it take the onpage optimization -keyword in title, text, etc-?

How do you determine the keyword difficulty?

Your Keyword Difficulty Score is based on the Domain Authority and Page authority for the top 20 search results that keyword is pulling on Google. These sites are analyzed using our Mozscape index to pull Page Authority and Domain Authority. These two metrics (along with a host of others from the Mozscape index) help create the Keyword Difficulty score.
