Default Play Store Search Results Problem Despite Efforts - Exact Name Ranking Very Low

The app was published about a month ago, and when I do a search for the exact name of the app Turbo Verse it ranks very low 25th at the highest, currently its #92.

I understand the basic SEO rules for the play store (downloads, rankings, compatibility etc.) but I feel this is an anomaly because this is the only app in the entire store that contains the words Turbo and Verse in the title and I can see no reason why it shouldnt be ranked very high for the exact name.

I was thinking it may have something to with the manifest so I will post it below, I have 18 reviews, mostly positive and over 100 downloads.

The full name of the App as it appears in the store is: Turbo Verse KJV - Bible Memory but I am only typing in the first part: Turbo Verse, but when I type the whole name into the search its still ranking about 9 or 10th


I would really appreciate any advice, I am a new developer and I would like to learn from my mistakes.
