Best Practices

App Title & Subtitle
High ImpactYour title (30 chars) and subtitle (30 chars) are the most weighted keyword fields. Choose wisely.

Screenshot Best Practices for ASO
Screenshots are the #1 conversion factor. Here's how to get them right.
Lead with Your Best Feature
Screenshot #1 is seen in search results. It needs to communicate your app's core value instantly.
Use Bold, Readable Headlines
Users scan quickly. Large text with high contrast ensures your message gets through at any size.
Show Real App UI
Apple and Google prefer screenshots showing actual app interface. Pure marketing graphics can get rejected.
Cover All Use Cases
Use 5-8 screenshots to tell a complete story. Each one should highlight a different feature or benefit.
Use All 10 Slots
Apple allows up to 10 screenshots. More screenshots = more chances to convince a potential user.
Test & Iterate
Use App Store product page optimization (Apple) or store listing experiments (Google) to A/B test.
