App Store Metadata Guidelines (iOS)
App Title (30 Chars)
Carries the highest ranking weight. Combine your brand with your 1 or 2 highest-intent keywords.
Subtitle (30 Chars)
Second highest weight. Describe value and include complementary search terms without repeating title words.
Keyword Field (100 Chars)
Comma-separated with no spaces. Never repeat words from Title or Subtitle, and avoid stop words.
Google Play Metadata Guidelines (Android)
Title (30 Chars)
Keep it concise and clear. Google Play strictly penalizes trademark spam and spammy emoji usage.
Short Description (80 Chars)
Strong ranking weight. First thing users see on mobile store pages before expanding.
Long Description (4,000 Chars)
Natural keyword density matters. Aim for 1.5% to 2.5% frequency on your target keywords. Over 3.5% risks penalty.
