Why We Updated the ASO Stack
Since Phiture first introduced the ASO Stack in 2017, it has become one of the industry’s most recognized frameworks for scaling app store optimization. 2026, however, demanded more than incremental updates.
Among the key changes, AI-assisted workflows have now become standard. Store metadata influences discovery across search, browse, ads, and promotional surfaces simultaneously. The line between paid and organic visibility has blurred. And app quality metrics, once a background concern, now function as primary gatekeepers to discoverability.
The ASO Stack 2026 Redux reflects this shift. It’s a structural response to how leading teams actually operate today, and provides a coherent system for managing the complexity of modern app stores.
Key Changes in the 2026 Stack
New Visibility Levers
The 2026 update introduces several elements that expand how apps get discovered:
Promoted In-App Purchases (iOS) allow developers to surface specific purchases directly in search results. Each IAP appears as its own card with name, icon, and pricing, transforming monetization elements into standalone visibility opportunities. A fitness app can now optimize its “30-Day Challenge” subscription for terms like “home workout plan,” competing at the purchase level rather than just the app level.
CPP Keywords and Search CSLs represent a fundamental shift in keyword strategy. Custom Product Pages on iOS and Search Custom Store Listings on Google Play now let developers create listing variants optimized for different search queries. Instead of a single listing trying to rank for everything, you can have dedicated pages for “note-taking app,” “task manager,” and “daily planner,” each with tailored metadata and creatives.
Search Tags (iOS) and Category/Tag indexing (Play) feed recommendation algorithms directly. These intent-based classifications determine which “Similar Apps” collections you appear in and how the store’s AI surfaces your app for related queries. Alignment between your tags, screenshots, and preview videos has become a ranking signal.
Browse and Explore Surfaces
The Browse layer has transformed from editorial curation into a hybrid environment. New surfaces include:
- Similar Apps and Recommended Apps modules powered by machine learning
- Organic Featuring alongside Paid Ads creating amplification opportunities
- Featured Promotional Content through Play Console for LiveOps events
Visibility on these surfaces depends on a mix of algorithmic signals, developer-supplied metadata, and app quality metrics.
App Vitals as a Central Pillar
Previously treated as a conversion factor, App Vitals now function as primary visibility signals. Google Play explicitly states that poor metrics “affect the discoverability of your app.” Apple’s performance dashboards track deletions, crash rates, and engagement with similar implications.
The benchmark matters: apps maintaining 99.8% crash-free sessions and sub-two-second cold-start times are more likely to appear in recommendation carousels and curated collections. A 1% increase in crash rate can suppress 20–30% of organic visibility within 48 hours.
Expanded Creative Assets
Visual assets now drive conversion more directly than ever:
- iOS App Preview Videos auto-play in search results, making the first 10 seconds your highest-impact conversion asset
- Promotional Artwork through In-App Events creates renewal moments for seasonal content and feature updates
- Play Store Preview Videos sit at the top of the listing hierarchy, influencing both visibility and conversion
Agentic Experimentation Tools
The most forward-looking addition to the Stack is a new category of testing tools. Unlike traditional AI that generates variants upon request, agentic tools manage the entire test lifecycle autonomously.
You input a goal (say “Increase conversion rate for the UK market by 12%,” for example) and the system generates hypotheses, launches A/B tests via platform APIs, evaluates performance data, iterates on winning combinations, and surfaces top performers for human review.
This shifts App store optimization teams from manual execution to strategic oversight. The best teams now run 50–100+ tests per quarter compared to 5–10 historically.
Supporting Insights Evolution
The 2026 Stack includes iOS Search Tags within App Analytics, providing a new visibility intelligence layer. Teams can now see how apps perform within intent-driven segments, not just keyword ranks, but how well you surface across multiple related intents.
This data enables creative optimization by context (tailoring screenshots to specific tag themes), visibility benchmarking (comparing tap-through rates in high-traffic categories), and competitive positioning (identifying underserved tags where you can dominate).
What This Means for Your Strategy
The stores reward coherence, consistency, and speed. The 2026 Stack reflects a world where:
- Keyword optimization happens at the variant level, not just the listing level
- Technical health is non-negotiable for sustained visibility
- Testing velocity compounds learning across weeks rather than quarters
- Discovery surfaces are personalized ecosystems, not static pages
Teams that align metadata, creatives, and product experience (and iterate on that alignment weekly) will compound their advantage throughout 2026 and beyond.

Frequently Asked Questions
What is the ASO Stack Framework?
The ASO Stack is a strategic framework developed by Phiture that maps how app store optimization actually works at scale. First introduced in 2017, it organizes ASO into interconnected pillars (visibility, Conversion, Tools, and Supporting Insights), showing how metadata, creative assets, app quality, and analytics work together to drive sustainable growth. The framework is continuously updated to reflect changes in how Apple App Store and Google Play surface and rank apps.
What are the biggest changes in the ASO Stack 2026?
The 2026 update introduces Promoted In-App Purchases, CPP Keywords, Search Tags, agentic experimentation tools, and repositions App Vitals from a background concern to a central visibility pillar. It also expands coverage of Browse and Explore surfaces, including Similar Apps, Recommended Apps, and Featured Promotional Content.
How do CPP Keywords and Search CSLs change keyword strategy?
Instead of optimizing a single listing for all target keywords, you can now create variant pages (Custom Product Pages on iOS, Search Custom Store Listings on Google Play) optimized for specific query intents. This multiplies your keyword footprint and lets you tailor creatives to match different user needs without diluting your core positioning.
Why are App Vitals now considered a visibility factor?
Google Play explicitly states that poor performance metrics affect discoverability. Apps with high crash rates or slow launch times see reduced placement in recommendation carousels and curated collections. Maintaining 99.8% crash-free sessions and sub-two-second cold starts has become a prerequisite for premium visibility.
What are agentic experimentation tools in ASO?
Agentic tools use autonomous AI agents to manage the full testing lifecycle (generating hypotheses, launching experiments, evaluating results, and iterating on winners) within defined guardrails. This shifts teams from manual test setup to strategic oversight, enabling 50–100+ tests per quarter versus the historical 5–10.
How do Search Tags affect app discovery on iOS?
Search Tags are intent-based classifications (like “Photo Editor” or “Workout Tracker”) that feed Apple’s recommendation algorithms. They determine which collections and related searches surface your app. Alignment between your assigned tags and your creative assets has become a ranking signal for these surfaces.
How often should ASO teams update their strategy based on the 2026 Stack?
The Stack emphasizes weekly iteration over quarterly planning. Teams should audit performance monthly, run continuous experimentation across creative and metadata variants, and maintain cross-functional collaboration with engineering on app quality metrics. The stores reward teams that adapt at the speed of the ecosystem.
