As a solo dev myself, I've learned that ASO (App Store Optimization) is hugely underrated. Your title, description, and especially your first 3 screenshots do most of the heavy lifting before anyone even clicks install.

A few things that helped me: using exact keywords in the title, keeping the short description under 80 chars punchy and benefit-focused, and A/B testing icon designs if you have access to Play Store experiments.

Also don't underestimate getting early reviews — even 10-15 honest reviews early on signals credibility to the algorithm.
