Who holds the top 10

Apple does not publish search volume. Demand is inferred from autocomplete (how few letters it takes before Apple suggests the phrase); difficulty from the rating volume, title targeting and quality of the current top 10. Treat both as estimates for comparing keywords against each other, not as absolute numbers.
