When we start ASO keyword research, remember there are no bad keywords.
Your 1st step is to get as much data as possible, gather as many keywords as you can and analyse them all using an ASO tool. Many at this early stage of ASO are quick to remove bad keywords.
It is too early because as we continue the process of narrowing down the keywords, we will eventually get to these bad keywords and filter them out from the list.
Keyword Research, therefore, should be seen as a way to seek the best keywords as well as filtering out the bad ones. Just get the data, add more keywords and then, later on, we choose via filtering out and keeping in keywords. Don’t overthink the process at this point.
