How to Fix Your App Store Subtitle

The subtitle (iOS) / short description (Play) is the second-most-weighted ASO field after the title. Common mistakes: repeating title keywords (waste), generic tagline (no keyword value), too long (truncation). The fix is secondary keywords with a clear benefit statement that doesn't duplicate the title. See the App Audit hub for full ASO context.

1. Limits and visibility

App Store subtitle:      30 characters
                         shown below app name on listing
                         indexed for search
Google Play short desc:  80 characters
                         shown in expandable section
                         indexed for search

2. The complementary keyword pattern

Title:    "Acme: CRM & Lead Tracker"
Subtitle: "Sales pipeline manager"     ← different keywords than title

NOT:
Subtitle: "CRM and lead tracker"       ← duplicates title (wasted)

The subtitle should add secondary keywords, not repeat title ones.
Together title + subtitle should cover 3-4 primary search terms.

3. Benefit clarity

Subtitle also affects conversion. Users see it before tapping. Bad subtitles look spammy; good ones promise concrete value:

Bad:      "Best app ever, top-rated, #1 sales tool"
Good:     "Track leads, close deals faster"
Best:     "Track leads. Close deals faster."  (period adds emphasis)

4. Patterns by app type

Productivity:     "[function] for [audience]"   "Notes for teams"
Utility:          "[verb] [object]"             "Convert any PDF"
Entertainment:    "[mood/genre] + verb"         "Calm puzzle games"
Health/Fitness:   "[goal] in [time]"            "Lose weight in 30 days"
Finance:          "[outcome] [audience]"        "Invest smarter, easier"

5. Test variations

Subtitle A/B testing same as title — App Store Connect and Play Console both support. Run minimum 7 days. Watch conversion rate (installs ÷ impressions) and search ranking changes simultaneously.
