18 items · Technical · Medium difficulty · 1 hour

Boost app visibility and conversions with this practical ASO checklist.

• Define target audience and priority markets

  List user personas, devices, and countries to focus localisation and keywords.

• Research high-value keywords using ASO tools

  Use tools (Sensor Tower, AppTweak, MobileAction) and store search suggestions for volume and difficulty.

• Select the primary keyword for the app title

  Choose the most relevant keyword that balances traffic and competition for your core value.

• Craft app title including the primary keyword

  Keep the title concise, readable, and within store character limits while including the primary keyword.

• Create a concise subtitle using secondary keywords

  Summarise the main benefit and include a secondary keyword naturally.

• Write an app description with natural keyword placement

  Lead with value, use short feature bullets, and avoid keyword stuffing for readability.

• Localize title, subtitle, and description for top markets

  Prioritise markets by installs and revenue; adapt messaging and keywords culturally.

• Design 3–5 store screenshots highlighting top features

  Show core flows, benefits, and a clear CTA in the first two frames.

• Write short caption for each screenshot

  Use action-focused captions that reinforce the visual and include a small keyword when natural.

• Use device mockups and clear visual hierarchy in screenshots

  Ensure text is legible at thumbnail size and focal points are obvious.

• Create a 15–30s preview video for the top slot

  Show the core experience quickly, include captions, and end with a call to action.

• Implement A/B tests for icon, screenshots, and first impressions

  Run controlled tests, track conversion lift, and keep tests running long enough for significance.

• Optimize the app icon for clarity at small sizes

  Simplify shapes, boost contrast, and test visibility against different backgrounds.

• Implement in-app review prompts at optimal moments

  Trigger after a successful action or clear positive engagement to raise rating likelihood.

• Respond to user reviews with helpful, timely replies

  Acknowledge issues, give steps to resolve, and invite private follow-up when needed.

• Analyze competitor keyword gaps and update metadata

  Identify keywords competitors rank for that you don't and add relevant, high-fit terms.

• Track store conversion metrics and user acquisition performance

  Monitor impressions-to-install, installs, retention, and A/B test results for decisions.

• Schedule regular metadata updates and A/B tests every 2–4 weeks

  Plan iterative changes, document results, and avoid changing too many variables at once.
