Since my games are not doing so good on Google Play(only have 20-30 downloads/day) I want to improve my title and description using popular keywords but at the same time find an unfilled niches .
I tried using Noble Samurai and Google Keyword Planner, but the results are not app store specific.
What I noticed, is that when I start typing on search box from Google Play, after each keypress I get 5 hints.
My thoughts is that those hints are based on the most searched terms and they should drive alot of people if your game description/title will contain them.
I managed to get a list of 1500 hints generated by the first 2 letters you first entered on search box (I omitted hints resulting from only one letter since are too popular and more that 3 letter will give way too many results )
I used a combination of numbers and letter "0123456789-_ abcdefghijklmnopqrstuvwxyz" and for the first 2 letters typed I got 38*38=1444*5 hints=7220. The actual result is less that that since some letter only give me 2-3 hints.
Here are the results for letters a,b and c. Please if anyone have an idea how to use this list as best as possible please share it.
If anyone want it please let me know and sorry if did not make myself to clear:P
