App Store vs Google Play ASO: Why One Strategy Won't Work for Both

The core difference: Apple and Google use different ranking algorithms, different metadata fields, different screenshot indexing, and different review handling. A keyword strategy that ranks well on the App Store might not work on Google Play, and vice versa.

This wasn't always the case. Five years ago, the stores were similar enough that a single ASO strategy could work reasonably well on both. But as each platform has added features (Apple's screenshot text indexing, Google's Store Listing Experiments, Apple's CPP organic search, Google's Collections and Engage SDK), the strategies have diverged.

The implication: if you're publishing on both platforms, you need two ASO strategies, two sets of metadata, two sets of screenshots, and two monitoring workflows. This is more work, but the alternative — one strategy for both — means underperforming on at least one platform.

App Store:

• •App name (30 characters): indexed for search, high weight
• •Subtitle (30 characters): indexed for search, complements app name
• •Keyword field (100 characters): indexed for search, not visible to users, comma-separated
• •Description (4000 characters): NOT indexed for App Store search (only for web search)
• •Promotional text (170 characters): not indexed, can be updated without new submission
• •Screenshots: text in captions is now indexed (since 2025)

Google Play:

• •App name (30 characters): indexed for search
• •Short description (80 characters): indexed for search, visible in search results
• •Long description (4000 characters): indexed for Play Store search (unlike App Store)
• •Developer name: indexed for search
• •Screenshots: text in captions is indexed
• •Feature graphic (1024x500px): not indexed, but affects conversion

Key differences:

1. 1.Description indexing: Google Play indexes your long description for search. The App Store does not. This means keyword-rich descriptions help on Android but not on iOS.

1. 2.Keyword field: the App Store has a dedicated 100-character keyword field. Google Play has no equivalent — you rely on the short and long descriptions for keywords.

1. 3.Short description vs subtitle: Google Play's short description (80 chars) serves a similar role to Apple's subtitle (30 chars), but with more than double the character budget.

1. 4.Promotional text: Apple has a promotional text field that can be updated without a new submission. Google Play has no equivalent — all metadata requires a new submission.

Strategy implication: on Google Play, invest in keyword-rich long descriptions. On the App Store, invest in the keyword field and screenshot captions (since the description isn't indexed).

App Store (since June 2025):

• •Apple uses OCR to extract text from screenshot captions
• •Extracted text is indexed alongside app name, subtitle, and keyword field
• •Keywords reinforced across metadata and screenshots carry more weight
• •Text must be readable by OCR (high contrast, adequate font size, clean typography)
• •All 10 screenshot slots provide indexing surface area

Google Play:

• •Google also indexes text in screenshots (the exact mechanism is less documented)
• •Screenshot text complements the indexed long description
• •Google's OCR is generally robust, handling various fonts and styles
• •Up to 8 screenshots provide indexing surface area

Key difference: on the App Store, screenshot captions are a primary keyword surface because the description isn't indexed. On Google Play, screenshot captions complement an already-indexed description, so they're additive rather than primary.

Strategy implication: on the App Store, put your most important keywords in screenshot captions. On Google Play, distribute keywords across the short description, long description, and screenshot captions.

App Store:

• •Rating prompt: system-level prompt (SKStoreReviewController), max 3 per year per app
• •No custom rating UI allowed
• •No rewards for ratings allowed
• •Developer can respond to reviews in App Store Connect
• •Users can update their reviews after developer responds
• •Rating recency weighted more in 2026
• •Review sentiment appears to affect ranking

Google Play:

• •Rating prompt: in-app review API, Google controls timing and frequency
• •No custom rating UI allowed
• •No rewards for ratings allowed
• •Developer can respond to reviews in Play Console
• •Users can update their reviews after developer responds
• •Google shows rating distribution (1-5 star breakdown) prominently
• •Reviews are public and permanent (unless removed for policy violations)

Key differences:

1. 1.Prompt frequency: Apple allows 3 system prompts per year. Google's in-app review API has its own frequency limits (Google doesn't disclose exact numbers, but typically allows one prompt per user per app).

1. 2.Rating display: Google Play shows the full rating distribution (how many 1-star, 2-star, etc.) on the store listing. The App Store shows only the average rating and total count. This means a few 1-star reviews are more visible on Google Play.

1. 3.Review prominence: Google Play reviews are more prominent in the listing — they appear immediately after screenshots. App Store reviews are lower on the page.

1. 4.Review removal: both platforms remove reviews that violate policies, but the processes differ. Google has a more accessible flagging system for policy-violating reviews.

Strategy implication: on Google Play, monitor your rating distribution closely — a spike in 1-star reviews is very visible. On the App Store, focus on maintaining a high average rating through prompt timing and responsive support.

App Store:

• •Product Page Optimization (PPO): test up to 3 variants of your default page
• •Testable elements: app icon, screenshots, app preview video
• •Cannot test: app name, subtitle, description, keywords
• •Requires 1,000+ daily impressions for significant results
• •One test at a time per app
• •Can also run PPO on Custom Product Pages

Google Play:

• •Store Listing Experiments: test variants of your store listing
• •Testable elements: app icon, screenshots, feature graphic, short description, long description
• •Cannot test: app name, developer name
• •More mature tool with more variants and granular controls
• •Can run multiple experiments simultaneously (with traffic splitting)
• •Results include conversion rate, retention, and install metrics

Key differences:

1. 1.Testable elements: Google Play lets you test text (short and long descriptions), while Apple's PPO is limited to visual elements (icon, screenshots, video).

1. 2.Maturity: Google's Store Listing Experiments have been around longer and offer more sophisticated controls (traffic splitting, multiple concurrent experiments).

1. 3.Metrics: Google provides more detailed metrics (retention, install quality) while Apple focuses on conversion rate.

Strategy implication: on Google Play, test your short description and feature graphic — these have high impact and are testable. On the App Store, focus PPO on your first screenshot and app icon, since text isn't testable.

App Store:

• •Localize metadata (app name, subtitle, keyword field, description, promotional text) per locale
• •Localize screenshots per locale (different captions, different example data)
• •40+ supported locales
• •Custom Product Pages can be localized per market
• •Localization is a top-3 ranking factor in 2026

Google Play:

• •Localize metadata (app name, short description, long description) per locale
• •Localize screenshots and feature graphic per locale
• •70+ supported locales (more than Apple)
• •Store Listing Experiments can be run per locale
• •Google's automatic translation feature can translate your listing (but manual localization is better)

Key differences:

1. 1.Locale count: Google Play supports more locales than the App Store, including more regional variants.

1. 2.Automatic translation: Google Play can auto-translate your listing into languages you haven't manually localized. This helps but isn't as good as proper localization. The App Store doesn't auto-translate.

1. 3.CPP localization: Apple's Custom Product Pages can be localized per market, which is powerful for targeted campaigns. Google Play doesn't have an equivalent to CPPs.

Strategy implication: localize for both platforms, but prioritize differently. On Google Play, leverage auto-translation for quick coverage, then manually localize high-value markets. On the App Store, manually localize metadata and screenshots for top markets, and localize your highest-traffic CPPs.

1. 1.Start with shared research: keyword research and competitor analysis can be shared across platforms. Identify your target keywords, then adapt for each platform's metadata fields.

• •App Store: app name (30), subtitle (30), keyword field (100), description (4000, not indexed)
• •Google Play: app name (30), short description (80), long description (4000, indexed)

1. 2.Create separate metadata for each platform:

• •Create your base design once
• •Export at App Store sizes (6.7", 6.5", 6.1", 5.5") with Apple device frames
• •Export at Google Play sizes (1080x1920px or higher) with Android device frames
• •Use different device frames for each platform

1. 3.Design screenshots once, adapt for each:

• •App Store: PPO on screenshots and icon
• •Google Play: Store Listing Experiments on screenshots, feature graphic, and descriptions

1. 4.Run separate A/B tests:

• •Track App Store ranking with ASO tools (AppTweak, Sensor Tower)
• •Track Google Play ranking separately (the algorithms differ)
• •Monitor review sentiment on both platforms

1. 5.Monitor separately:

• •Prioritize the same top markets on both platforms
• •Adapt localization for each platform's locale options
• •Use a screenshot generator that supports multi-language export

1. 6.Localize for both:

The goal: a unified workflow that produces platform-specific output. Design once, adapt for each platform, monitor separately, and optimize based on each platform's data.
