App Store SEO and Google Play optimization aren't the same discipline wearing two different outfits — they run on different algorithms, different metadata fields, and different ranking signals entirely.
If you're shipping on both iOS and Android, you're not doing one ASO campaign — you're doing two. The stores share the same goal (users finding apps they'll love) but use meaningfully different mechanisms to get there. Treating them identically is one of the most common cross-platform mistakes.
Metadata Fields: A Tale of Two Systems
Apple gives you: a 30-character title, a 30-character subtitle, a 100-character keywords field, and a promotional text (not indexed). Your description is not indexed for search at all on iOS — it's purely a conversion tool.
Google Play gives you: a 50-character title, an 80-character short description, and a 4,000-character long description. There is no separate keywords field — Google indexes everything in your listing, including the long description. This means your Android description is both a conversion tool and an SEO document.
How Keyword Indexing Differs
On iOS, keywords must be explicitly placed in the designated metadata fields. If a word isn't in your title, subtitle, or keywords field, you won't rank for it — no matter how many times it appears in your description. This makes every character precious.
On Google Play, the algorithm is closer to traditional web SEO. Keywords in the title carry more weight, but the description is actively crawled. Keyword density and natural usage matter. The practical implication: your Android description needs to be written with keyword strategy in mind, while your iOS description doesn't.

Ratings and Reviews: Shared Signal, Different Weight
Both stores factor reviews and ratings into search ranking and featuring decisions. But there's an important difference in how fresh reviews are weighted. Google Play places more emphasis on recent reviews — a surge of 5-star reviews after an update can meaningfully lift rankings within days. Apple's algorithm is more stable but also slower to reflect quality improvements.
Screenshot and Graphic Differences
Apple requires device-specific screenshot sizes for iPhone and iPad. Google Play is more flexible but adds a feature graphic (1024×500px) that appears prominently at the top of your listing — it functions like a hero banner.
Google Play also prominently surfaces your promo video if you have one, showing it before screenshots in the store listing carousel. If you're not using the feature graphic and video capabilities on Android, you're leaving first-impression real estate empty.
A Practical Cross-Platform Workflow
- Write your title strategy for iOS first (30 chars), then expand slightly for Android (50 chars)
- Build your iOS keywords field independently from your Android description keywords — they serve different purposes
- Create screenshots in both required sizes, but maintain consistent messaging and visual style
- Review ratings and respond on both stores — response rate is a quality signal on both platforms
- Track conversion separately per store — your iOS CVR and Android CVR will differ, and improvements to one won't automatically improve the other
Running keyword research, metadata, and screenshot workflows separately for each store is a lot to juggle manually. A cross-platform ASO tool that understands both algorithms can keep your iOS and Android strategies aligned without duplicating the work.
