Mobile SEO and ASO: Understanding the Challenges

Two Complementary Disciplines

Mobile app visibility relies on two distinct but complementary disciplines:

ASO (App Store Optimization) optimizes visibility directly in stores:

  • Store keywords: title, subtitle, keyword field (iOS), short and long description
  • Visuals: icon, screenshots, preview video
  • Social proof: ratings, reviews, download volume
  • Behavioral metrics: store-listing-to-install conversion rate, retention, uninstalls

Mobile SEO optimizes visibility in search engines:

  • Google App Packs: app results displayed in mobile SERPs
  • App Indexing: indexation of in-app content by Google
  • App landing pages: optimized web pages redirecting to the store
  • Deep linking: deep links to specific in-app content
  • Structured data: SoftwareApplication and MobileApplication markup

The GEO Challenge for Mobile Apps

In 2026, a new challenge emerges: GEO (Generative Engine Optimization) for applications. Generative AIs increasingly recommend apps in their responses:

  • “What is the best meditation app?” → ChatGPT, Perplexity and Google AI Overviews cite specific apps
  • “App to learn Japanese” → AIs synthesize rankings with direct store links
  • AI-referred traffic surged by 527% year-over-year, and this trend now impacts app recommendations

To be cited by AIs as the “best app” in your category, you need to optimize web content (landing pages, feature pages) with structured data SoftwareApplication, strong E-E-A-T signals, and structured content that answers users’ comparative queries.

Why Combine Mobile SEO and ASO

Data shows that users discover apps through multiple channels:

  • 70% of installs come from store searches (ASO)
  • 27% of store traffic is referred by web search engines (mobile SEO)
  • “Best app for…” queries on Google increased by 65% between 2024 and 2026
  • Generative AIs are becoming a fast-growing app recommendation channel

A siloed SEO or ASO strategy leaves a significant share of visibility untapped. The best-performing agencies combine both disciplines.

Selection Criteria for a Mobile SEO / ASO Agency

Essential Skills

  • ASO expertise: store keyword research, metadata optimization, A/B testing on visuals, review management
  • Mobile technical SEO: App Indexing, deep linking, SoftwareApplication structured data, mobile Core Web Vitals optimization
  • Data analysis: ASO tracking tools (AppTweak, data.ai, Sensor Tower), multi-channel attribution
  • Mobile content strategy: app landing pages, comparative pages, feature guides
  • GEO and AI: optimization for app recommendations in AI responses
  • Store guidelines knowledge: App Store Review Guidelines (Apple), Google Play Developer Policy

Quality Signals to Verify

  • App portfolio successfully optimized (store rankings, download metrics)
  • Documented case studies with ASO and mobile SEO KPIs
  • Tools used: professional ASO platform, not just manual estimates
  • Geographic coverage: ability to optimize across multiple countries and languages
  • Continuous optimization approach: ASO is not a one-shot, it’s an iterative process
