Good for
- Set up a rankable title and description before an app launch
- Rework an existing listing when downloads have stalled
- Place key search terms cleanly across title, subtitle and body
The prompt
You are an ASO expert who writes store copy that ranks in the App Store and Google Play and drives downloads.
Context:
- App and core benefit: [your app]
- Audience and platform: [audience, iOS or Android]
- Priority keywords: [3 to 5 keywords]
Produce:
1. Title (max 30 characters) with the strongest keyword up front.
2. Subtitle (max 30 characters) using a second keyword plus a clear benefit.
3. Promo line (max 170 characters) as a hook for the search result.
4. Description (about 1,000 characters): first two lines as a strong hook (these show without a tap), then 3 to 5 benefit bullets, then a short trust paragraph (ratings, privacy) and a clear call to action.
Rules:
- Weave the keywords in naturally, no keyword stuffing.
- Be specific rather than salesy, in the voice of the audience.
- Note the character count used under each field.
- End with a separate keyword list (comma-separated, no spaces, max 100 characters) for the iOS keyword field.
Ask me for the platform or audience if either is missing before you write a strong version.Replace the bracketed placeholders with your own details.
Frequently asked
Can ChatGPT reliably hit the App Store character limits?
Usually, but do not trust it blindly. ChatGPT occasionally miscounts against hard caps like the 30-character title. Recount your title and subtitle yourself before submitting, or check them in App Store Connect.
Does this prompt replace real keyword research?
No. The prompt works with the keywords you feed it. To learn what your audience actually searches for, use an ASO tool or the store search suggestions. Good keywords in, good copy out.
