App Store Optimization (ASO) Tips

ASO is the SEO of app stores. It improves visibility and downloads.

Tips for Google Play Store:

  • Utilize high-traffic keywords in title and description
  • Include a compelling call-to-action
  • Utilize high-quality screenshots
  • Prompt user ratings and reviews

Tips for Apple App Store:

  • Select strategic keywords in the keyword field
  • Make title brief but keyword-rich

Common Mistakes to Avoid

  1. Ignoring Guidelines: Each platform has specific, non-negotiable guidelines.

  3. Uninspired App Descriptions: Failing to convey your app’s value turn users away.
  4. Abusing Permissions: Asking users for overly invasive permissions will get your app into trouble.
  5. Failure to Optimize: Without proper ASO, your app may never be discovered.
