Step 4: Keyword suggestions and ranking
The Intelligent Keyword Suggestions module is another easy way to quickly generate relevant keywords. I generally recommend going here after Keyword Spy. It depends on having a reasonable set of seed keywords, but can quickly provide a lot of good suggestions for any app. Use it in conjunction with the Keyword Spy and Keyword Research tool to generate a strong set of relevant keywords that you can potentially use with your app.
The Intelligent Suggestions Tool displays data about the keywords, such as the Traffic Score, Difficulty or number of competing apps. Keep these stats in mind when selecting keywords, as trying to compete for difficult keywords is one of the basic mistakes an app developer can make.
