Where these numbers come from
Popularity is modeled, not measured. Apple publishes no search volume, so this is a proxy built from where a term surfaces in App Store autocomplete, how many completions it carries and how many apps compete for it. Read it as a direction, never as a number of searches.
Difficulty weighs how strong the apps already ranking are: their ratings, their rating counts, and how many of them put the term in their title on purpose.
Opportunity blends the two geometrically, so a very hard keyword cannot score well on demand alone. It is the column worth sorting by if you are picking something to build.
Genre is read off the apps Apple returns for the term, not assigned by hand: the most common App Store category in its top results.
