10 ASO Mistakes That Quietly Kill Your App Store Listing

We audited 200+ indie iOS apps that asked for help moving their install rate above 2%. The same 10 mistakes showed up over and over. Most are 30-minute fixes that move your conversion needle measurably.

1. First screenshot is a feature collage

Don't try to show every feature in your first shot. Pick ONE outcome and own it. The viewer doesn't read; they pattern-match. A clean hook + one screen converts 2× a busy collage.

2. Headline is a feature, not a benefit

"AI-powered receipt scanning" is a feature. "4 hours back per week" is a benefit. Always headline the outcome.

3. Status bar shows real time

Real status bars (23:00, low battery, Do Not Disturb on) read as "this is somebody's actual phone" — distracting and unprofessional. Apple's marketing standard is 9:41, full bars, full battery, no notifications. Use it.

4. Localization is shallow

Translating only the headline and leaving the in-phone UI in English is the #1 ASO mistake we see. Spanish App Store visitors expect Spanish UI inside the phone too. Same for German, Japanese, Arabic — every locale.

5. Missing 6.7" assets

If you uploaded 5.5" screenshots in 2020 and never updated, every modern iPhone visitor sees a stretched, low-resolution version. Generate 6.7" assets — Apple auto-scales them down.

6. App icon doesn't match screenshot 1

Your icon and your first screenshot should share a colour anchor. If the icon is teal and the first shot is fuchsia, the listing reads as inconsistent — installs drop.

7. Subtitle uses generic words

Apple's algorithm weights the 30-character subtitle more than most devs realize. Spend it on a high-intent keyword ("Sleep tracker, smart alarm") rather than a tagline ("Sleep, redefined").

8. No before/after pair

Apps that sell a transformation (fitness, productivity, finance) convert significantly higher when shot 2 or 3 visually shows the user's life before vs after. "Spreadsheet chaos → one clean view" is the canonical example.

9. Banned phrases in copy

"#1", "Best", "Editor's Choice", "Award-winning" — every one of these triggers an App Review flag and (at best) a soft rejection. At worst, a permanent listing penalty.

10. Never iterating

Top-quartile apps update their screenshots every 6–8 weeks. Most indie apps update them once at launch and never again. The asset that converts in January won't convert in November.
