App Store Search Is the Primary Discovery Channel for Apps.
According to Apple, 65% of app downloads originate from App Store search. The top three search results capture 70% of all clicks. Improving your app ranking by one position increases downloads by 30-50% according to SplitMetrics data. Despite this, most apps neglect ASO beyond basic keyword optimization. Advanced ASO strategies combine keyword optimization, conversion rate optimization, and engagement signals to dominate app store search results.
At x13apps, we optimize apps for maximum visibility and conversion. Here are our advanced strategies.
Keyword Research and Optimization
Keyword research for app stores differs from web SEO. App Store keywords are matched against the app title, subtitle, and keyword field. Google Play matches against title, short description, and full description. The App Store keyword field has a 100-character limit; use every character. Avoid spaces between keywords (separate with commas). Do not repeat keywords already in your title or subtitle. Use all available field space: App Store title (30 chars), subtitle (30 chars), keyword field (100 chars).
Research competitor keywords using tools like Sensor Tower, AppTweak, or Mobile Action. Identify high-volume, low-competition keywords. Target long-tail keywords with specific purchase intent: "project management app for freelancers" rather than "project management app". Monitor keyword rankings weekly and adjust based on performance. Localize keywords for each target market. An English keyword may have no equivalent in Korean or Japanese. Hire native speakers for localization, not machine translation.
Visual Assets That Convert
Your app icon is the first visual users see. It must be: simple (recognizable at 60x60px), distinctive (stands out in a grid of icons), and relevant (communicates app purpose). Test multiple icon variants. The best-performing icon can increase conversion by 25%. Screenshots are your app store page: first two screenshots determine whether users scroll further or leave. Lead with your strongest value proposition, not your login screen. Use captions to highlight specific features and benefits.
App preview videos (App Store) and promo videos (Google Play) increase conversion by 20-35%. The first 3 seconds determine whether users watch the rest. Start with your most compelling feature. Show real app usage, not animated mockups. Keep videos under 30 seconds. Update visual assets seasonally: holiday themes, feature updates, and new device support keep your listing fresh. Fresh visual assets signal to the app store algorithm that your app is actively maintained.
Leveraging Ratings and Reviews
Ratings and reviews are the strongest social proof. Apps with 4+ stars have 3x higher conversion rates than 3-star apps. Prompt users for ratings at positive moments: after completing a task, achieving a milestone, or using the app consistently for a week. Use SKStoreReviewController (iOS) or In-App Review API (Android) for native rating prompts. Never interrupt users during onboarding or after errors.
Respond to every review, positive and negative. Thank positive reviewers and address their specific feedback. For negative reviews, apologize, explain how you are fixing the issue, and invite the user to contact support. Users who see developer responses to reviews are 40% more likely to install according to AppFollow. Respond within 24 hours when possible.
