Once you have your seed keywords, the next step is to come up with a list of variations and to add it to your database of keywords. 

Sample Seed keyword (“Fitness”) variations include: “Fitness App, Fitness Tracking, Fitness Calculator” and more. 

This is the beginning of your long-tail keyword list. 

Come up with as many as you can and set a target number of variations per seed keyword. 

You can turn to good old Google and its suggested search terms as well to help you come up with seed keyword variations. 

Don’t worry if some of these variations don’t make any sense at this point. 

Don’t delete or cancel any of them just yet. If there are crappy ones, include them as well. 

We need bad data too so we can validate good keywords. 

When the time comes, the ASO tool will let you know if it makes sense to use it or not. 

No need to overthink the process – we just need to gather data – the more the merrier.
