Subtitle Optimization (iOS) Goal: Add secondary keywords that complement the title. Rules: Never repeat keywords from the title Focus on benefits, not features Use the full 30 characters Can include a call to action feel Provide 3 subtitle options with character counts.

Hook (first 3 lines) — This is all users see before "more". Make it count. 2. Social proof — Awards, press mentions, user count, rating 3. Key features — 4 6 bullet points with benefits, not just features 4. How it works — Simple 3 step explanation 5. Testimonial or review quote — Real user voice 6. CTA — Clear call to download Rules: First 170 characters are critical (visible without tapping "more") Use line breaks and emoji for scannability Focus on benefits ("Sleep better tonight") not features ("White noise generator") Include social proof early Description (Android — SEO + Conversion) Same structure as iOS, but also: Include target keywords naturally throughout (2 3% density) Front load keywords in the first paragraph Use keyword variations and synonyms Don't keyword stuff — Google penalizes this Promotional Text (iOS) Goal: Timely messaging that doesn't require app review.
