Keyword Set Building
Keyword difficulty score
The more specific a keyword you use, the more difficult it is to rank high for this keyword. Keywords such as "Poker" or "Card game" have high difficulty. It means that if you try to rank for a keyword "Poker", your app will be almost unreachable for users who type this keyword. Alternatively, you can create a long-tail keyword like "Free online poker" or "Poker deluxe pro" – these phrases have lower difficulty, so you can rank higher.
