Territory-Level ASO: Keyword Strategy Across Apple's 39 Markets

Apple indexes keyword metadata per storefront — your US keyword field doesn't carry over to Brazil, Japan, or Germany. Here's how to build a territory-aware ASO strategy before Q4 traffic peaks.

By the AppsOps news desk · October 17, 2026

Apple's App Store treats each of its 39+ storefronts as a semi-independent search index. Your keyword field in the US storefront is completely separate from the one in Brazil, Japan, or Germany — which means you have up to 3,900 keyword characters spread across markets, but the average indie app uses fewer than 150 of them. That gap has always existed, but it matters more heading into Q4 2026, when non-US storefronts are driving a growing share of global download volume.

How Apple's Per-Storefront Index Actually Works

When you submit a localization through App Store Connect, each language you ship gets its own set of indexed metadata fields:

Title — 30 characters, highest indexing weight
Subtitle — 30 characters, strong secondary signal
Keyword field — 100 characters, iOS only, not shown to users
Promotional text — 170 characters, not indexed for search

Apple applies these independently per storefront. A user searching the Brazilian App Store sees rankings influenced by your pt-BR metadata — not your en-US metadata. If you've shipped a Portuguese localization but left the keyword field blank or with English terms copy-pasted from your US submission, you're competing in Brazil at a structural disadvantage against apps that have localized their keywords.

This isn't a new rule. What's changed is the competitive density. As ASO tooling has matured and more teams have learned to optimize for the US store, non-English markets increasingly separate the teams who've done territory-level keyword work from those who haven't.

A Tiered Approach to Territory Keyword Work

Full keyword optimization across all 39 markets is not realistic for a solo developer or small team. A tiered model keeps the workload manageable while covering the highest-leverage opportunities:

Tier	Markets	Recommended action
Priority	US, Japan, Germany, UK, Australia	Full keyword optimization, localized screenshots, A/B testing via PPO
Growth	Brazil, France, Canada, South Korea, Mexico	Keyword optimization + translated screenshots at minimum
Presence	Remaining 30+ markets	Localized title and subtitle; keyword field is secondary effort

Japan deserves special attention in the Priority tier: Japanese App Store search is highly keyword-driven, users search in Japanese (hiragana/katakana/kanji), and the competitive landscape in most categories is notably different from the English-language stores. Many Western developers skip Japanese keyword optimization and leave meaningful organic volume on the table.

The October Mid-Q4 Audit

Mid-October is a good moment to close keyword gaps before Q4 traffic peaks in November and December. Ranking changes from a metadata update can take 2–4 weeks to stabilize, so submitting a keyword update now gives you time to benefit from it during peak season.

A quick audit in App Store Connect:

Go to App Store Connect → [Your App] → App Information → Localizations
For each active localization, open the keyword field and check its character count
Flag any localization where the keyword field is empty, under 50 characters, or identical to your English submission
Prioritize filling those gaps in your top 5 storefronts by download volume (visible in App Analytics → Sources → App Store Browse/Search by territory)

A few practical notes on keyword construction for non-English fields:

Do not repeat words from your title or subtitle — Apple already indexes those, and keyword field space is too scarce to duplicate them
Use commas, not spaces, as separators — Apple treats the keyword field as a comma-separated list; spaces between terms waste characters
Localize conceptually, not literally — a direct translation of your English keywords often misses how users in that market actually search; a native speaker or local ASO review is worth the investment for Priority-tier markets

How Localization Cost Scales

For teams considering expanding to new storefronts, AppsOps's localization cost breakdown covers what it actually takes to add a new market — metadata only versus full screenshot localization. Metadata-only for a new language is typically the lowest-cost ASO lever available. See also the territories overview for a breakdown of Apple's 44 pricing tiers and how they map to major markets.

Reports suggest that localized screenshots convert better than localized text alone in A/B tests, but localized metadata is the prerequisite — you need to appear in search before you can convert. Getting keyword coverage right across your top territories first is the correct sequencing.
