What Is Our ASO Service?
App Store Optimization is how your app gets found organically — without paying for every download. We optimize your app's metadata (titles, subtitles, descriptions, keyword fields) so it ranks for the terms your users actually search for.
What makes our approach different is scale and precision. Traditional ASO involves an analyst reviewing a spreadsheet of keywords, making gut-feel decisions about which ones to target. Our system processes every keyword across every locale simultaneously, scoring each one with our proprietary KEI methodology to surface the highest-impact opportunities first.
We manage both iOS and Android with platform-specific strategies. iOS has strict character limits (30 title + 30 subtitle + 100 keyword field). Android's 4,000-character description is fully indexed for keywords. Each platform needs a different tactical approach — and our system handles both without one falling behind the other.
What's Included
KEI-Based Keyword Research
Our proprietary Keyword Effectiveness Index scores every opportunity by balancing popularity against difficulty — across all target markets simultaneously. No more gut-feel keyword decisions.
Multi-Locale Management
We optimize across 11 simultaneous markets — US, UK, Brazil, Germany, Spain, Hungary, France, Canada, Mexico, Australia, and more. Each locale gets tailored keyword strategy, not copy-paste translations.
Metadata Optimization
Titles, subtitles, keyword fields, descriptions, and promotional text — all optimized within platform constraints. iOS 160-character budgets. Android 4,000-character descriptions with target keyword density.
Screenshot Caption Optimization
iOS now indexes screenshot captions for keyword ranking. We optimize captions as an additional keyword surface — a tactical advantage most ASO practitioners haven't caught up with yet.
Cross-Platform Strategy
iOS and Android require different approaches. We manage both with platform-specific tactics — singular keyword forms for iOS, natural language density for Android — without one platform falling behind.
Competitive Analysis
We monitor competitor metadata, keyword strategies, and ranking movements. Our system flags when competitors make changes and identifies gaps in their coverage that represent your opportunities.
The KEI Scoring System
Most ASO tools show you keyword popularity and difficulty as separate metrics. You're left to eyeball which keywords are worth targeting. Scale that across 11 locales and hundreds of keywords, and you're gambling.
Our Keyword Effectiveness Index solves this. KEI is a composite score that balances search popularity against ranking difficulty, weighted by additional factors like keyword length and cross-locale validation. A high-KEI keyword is one where the effort-to-reward ratio strongly favours you.
The system calculates KEI for every keyword in every locale, then ranks them. Instead of reviewing thousands of data points, you see a prioritised list of your highest-impact moves. The same keyword might be high-KEI in Hungary but low-KEI in the US — the system catches this automatically.
KEI analysis runs at the start of every optimization cycle. Before any metadata changes, we know exactly which keyword swaps will produce the biggest ranking improvements. No guesswork. No wasted cycles.
Systematic Optimization Cycle
Every optimization follows a systematic cycle. Automation handles the data processing. Humans make the strategic calls. Every change is tracked.
Automated Data Collection
Weekly automated snapshots capture install metrics, keyword rankings, conversion rates, and competitive positions across every active locale. No manual data pulling. No missed weeks.
AI Analysis & KEI Scoring
The system processes the latest data, calculates KEI scores, compares against previous cycles, and identifies risers, fallers, and new opportunities. It produces a prioritised recommendation set.
Human Gate: Strategy Review
Every recommendation is reviewed by our team before implementation. We validate the system's suggestions against market context, creative judgment, and business priorities. Nothing goes live without human approval.
Implementation & Tracking
Approved changes are implemented and logged in an append-only change ledger. Every keyword swap, every metadata update, every locale change is tracked with before-and-after context for full auditability.
Cross-Channel Flywheel
Most agencies treat ASO and paid ads as separate disciplines with separate teams. We connect them.
Our ASO system feeds keyword intelligence directly into our Apple Search Ads campaigns. High-KEI organic keywords with poor ranking positions become prime bidding candidates. Keywords where you already rank #1 organically don't need paid spend — that budget moves elsewhere.
The reverse is equally valuable. Apple Search Ads surface search terms that real users type — including terms you'd never think to target organically. These discoveries flow back into ASO keyword candidate lists for the next optimization cycle.
This bidirectional data flow means each channel makes the other smarter. It's a compounding advantage that accelerates over time.

Frequently Asked Questions
What is App Store Optimization (ASO)?
ASO is the process of improving your app's visibility in the App Store and Google Play by optimizing keywords, titles, descriptions, and other metadata. It's essentially SEO for app stores — the goal is to rank higher for terms your target users are searching for.
What is the KEI scoring system?
KEI (Keyword Effectiveness Index) is our proprietary scoring methodology that evaluates every keyword opportunity by balancing search popularity against ranking difficulty. Rather than guessing which keywords to target, KEI surfaces the highest-impact opportunities across all your markets simultaneously.
How many locales can you manage?
We currently manage 11 active locales including the US, UK, Brazil, Germany, Spain, Hungary, France, Canada, Mexico, and Australia. We can expand to any App Store or Google Play storefront where your app is available.
How long before I see ASO results?
Keyword ranking changes typically appear within 1-2 update cycles (4-8 weeks on iOS, 6-8 weeks on Android). However, the compounding effect of systematic optimization means results accelerate over time as your metadata, ratings, and keyword coverage strengthen together.
Do you optimize for both iOS and Android?
Yes. We manage both platforms with platform-specific strategies. iOS has a 160-character budget across title, subtitle, and keyword field. Android's long description is fully indexed with a 4,000-character limit. Each platform requires different tactical approaches.
How does ASO connect to Apple Search Ads?
Our ASO and Apple Ads systems share bidirectional data. High-performing organic keywords inform paid bidding strategy, while search term discoveries from paid campaigns become ASO candidates. This cross-channel flywheel is a key differentiator of our approach.
Is there an ASO agency in Budapest?
Yes. Prioritised Labs runs App Store Optimisation from Budapest across 11 locales, using our proprietary KEI scoring to surface the highest-impact keywords instead of guessing. We validated the system on our own app — from 15 to 125 ranked keywords, with 9+ at #1.
