ASO is keywords (visibility) + screenshots (conversion). You optimized half. Your impressions probably grew but nobody installs because the listing doesn't sell. Screenshot 1 + 2 carry 80% of the conversion decision. Test rewriting screenshot 1 with a clear value-prop overlay, ship it for 2 weeks, compare against baseline.
My ASO keywords are set but installs are flat because the listing converts poorly. Rewrite screenshots 1 and 2 to carry the conversion: a clear value-prop overlay for [app] and a supporting benefit. Give me the overlay copy and layout so I can ship it and A/B against the current listing.
