What Is App Store Optimization for Mobile Games
App Store Optimization, or ASO, is the discipline of improving how a mobile game appears and converts inside the App Store and Google Play.
For mobile games, ASO usually covers metadata, keyword targeting, icons, screenshots, preview videos, custom product pages, in-app events, localization, and store listing experiments. Its job is simple: help more qualified store visitors become players.
That makes ASO different from paid user acquisition. UA brings traffic to the store page; ASO improves what happens once that traffic arrives.
This guide focuses specifically on ASO agencies for mobile games. It is not a comparison of full-service growth marketing agencies or paid user acquisition agencies. The agencies here are evaluated primarily on App Store and Google Play optimization capability: metadata, store listing conversion, creative asset testing, localization, app store experiments, and Apple Search Ads integration where relevant.
Why ASO for Games Is Mostly Store Conversion
That said, ASO’s weight in the overall mix is meaningfully smaller for games than for non-gaming apps, and it’s worth being clear about why. The reason is that one major pillar of ASO — search optimization — is often less influential in gaming than it is in non-gaming app categories.
Most games today are discovered through paid ads or influencers, and it’s uncommon for a player to open the App Store and search for generic terms like “match-3 game” or “racing game.”
When search does happen in gaming, it’s usually for brand terms: a player types “Candy Crush Saga” or “Clash of Clans” because they’ve already decided which game they want. As a general rule, the more casual the game, the less likely anyone actively searches for it.
Hypercasual games are the clearest example. With lifetime player spend measured in days or at most a few weeks, no one is searching for them by name or genre. The exceptions are games with niche appeal or a major IP behind them (Warhammer, for instance), which can see modest organic search traffic, but these are the exceptions rather than the rule.
What this means in practice is that ASO for mobile games is usually closer to store listing conversion optimization than traditional search SEO. It is about the icon, screenshots, preview video, metadata, custom product pages, and other prominent elements that decide whether a store visitor installs.
Because every conversion point gained can reduce effective cost per install, ASO becomes a direct lever on store-page efficiency. An icon or screenshot test that improves conversion does not just move an organic metric; it can improve the economics of every traffic source that sends users to the store page, including paid UA.
That connection between paid traffic and store conversion is the reason strong ASO agencies serving games rarely treat the store page in isolation. The goal is not only to improve keyword rankings or impressions, but to improve the store page in a way that supports installs, paid efficiency, creative testing, and long-term growth.
For a game in active growth, the best ASO work is connected to the broader acquisition system without becoming the same thing as UA. Store experiment results can inform paid creative, and paid campaign learnings can inform the next round of screenshots, icons, custom product pages, and metadata tests.
It’s with that framing in mind that the rest of this article evaluates the agencies worth considering.
How These ASO Agencies Were Selected
This is not a ranking. The list below covers the agencies that mobile game studios are most likely to encounter when evaluating ASO partners.
For this guide, agencies were assessed specifically on App Store Optimization capability, not general mobile marketing reputation. The most important evaluation criteria were:
- ASO scope: metadata, keyword strategy, screenshots, icons, preview videos, custom product pages, in-app events, localization, and testing,
- specialization: pure ASO specialist, ASO platform-led team, or broader mobile agency with a credible ASO practice,
- gaming relevance: mobile games only, strong gaming portfolio, or general app portfolio with selected gaming experience,
- experimentation depth: ability to run meaningful store listing tests rather than minor creative tweaks,
- integration with Apple Search Ads and paid UA where relevant,
- published case studies, client examples, or evidence of measurable store-page impact.

12 Best ASO Agencies for Mobile Games in 2026 & Beyond
AppAgent
Founded 2016 · ~40 people · Prague · Mobile games only
AppAgent is a mobile-game-exclusive growth and creative agency where ASO is handled as part of a broader growth or creative engagement rather than sold as an isolated checklist.
AppAgent has extensive experience working with casual and mid-core mobile games, where store conversion optimization directly impacts UA efficiency and long-term growth.
For the purpose of this ASO comparison, AppAgent is evaluated specifically on store listing strategy, metadata, localization, creative asset testing, app store experiments, and the connection between ASO work and paid acquisition performance.
The integration is the point: ASO conversion data can feed creative decisions for paid UA, while paid campaign learnings can inform the next round of icons, screenshots, custom product pages, preview videos, and metadata tests. AppAgent has worked on ASO with publishers including Supercell, Metacore, Goodgame Studios, Social Point, and Netflix Games.
A representative published case is Star Stable Online, the mobile version of the iconic horse-riding web game from Star Stable Entertainment. The brief was to revitalize the app’s visual appeal and attract a fresh audience after the initial surge of existing web players had tapered off. Over a six-month engagement, AppAgent built a dynamic ASO testing framework running over 30 store experiments, with a deliberate focus on meaningful variation such as different layouts, art styles, screenshot directions, and visual concepts rather than the minor color tweaks and caption changes that typically produce little lift. The work also included metadata optimization around high-traffic keywords (“horse,” “horses,” “horse game”), and in-app events to expand search result visibility. The outcome was that iOS conversion rate in the US was up 54%, App Store Browse conversion up 50%, and top keyword positions for “horse” and “horse games” rising from 4th to 1st place.
Best for: Mobile game publishers who want ASO integrated with creative strategy and paid acquisition, rather than bought as a siloed deliverable. Especially relevant for teams that need gaming-specific ASO support across metadata, localization, icons, screenshots, custom product pages, app store experiments, and store conversion.
Phiture
Founded 2016 · ~120 people · Berlin · Apps & games
Phiture began as an ASO and CRM specialist before expanding into paid UA and retention, and ASO remains one of its strongest practice areas. The agency is widely respected for its thought leadership. It co-authored Advanced App Store Optimization: The Complete Guide to ASO, and runs the ASO Stack Slack community.
ASO services are tightly integrated with Apple Search Ads via Phiture’s proprietary Catchbase bid optimization tool, which applies machine learning to ASA auction bidding.
For gaming ASO the most relevant offering is PressPlay, Phiture’s AI-driven Play Store A/B testing tool that achieved +57% conversion rate for Avakin Life.
In early 2026, Phiture was acquired by Precis, a Stockholm-based performance marketing group.
Best for: Large app publishers (and select game studios) whose primary growth lever is ASO at scale, where tool depth, experimentation velocity, and localization breadth matter more than gaming specialization.
ConsultMyApp (CMA)
Founded 2016 · ~25 people · London · Apps & games
ConsultMyApp is a full-service mobile marketing agency where ASO is one of six integrated services alongside UA, CRM, BI & analytics, creative, and strategy.
The agency was named ASO Company of the Year at the 2023 App Growth Awards and won the 2024 App Marketing Campaign of the Year for its work with Macy’s. Published client work includes King, and MONOPOLY GO! though the agency’s center of gravity is clearly on consumer and commerce apps rather than games specifically. ASO is integrated with ASA management as a single practice, which CMA frames around “traffic cannibalization” between organic and paid as the core optimization challenge.
Best for: Consumer app and commerce brands (and larger gaming publishers with broad app portfolios) that want ASO as part of an integrated full-funnel engagement with a London-based senior team.
yellowHEAD
Founded 2013 · 130+ people · Tel Aviv (with NYC and European offices) · Apps & games
yellowHEAD is a full-service performance marketing agency with one of the more mature ASO practices in the gaming space, having built its reputation alongside early gaming clients and expanded from there.
The ASO scope is comprehensive: keyword optimization, CRO, localization, LiveOps and in-app events, Custom Product Pages, A/B testing, and ASO consultancy, all managed alongside paid UA, creative production, SEO, and more recently GEO (Generative Engine Optimization).
Published clients include Zynga, Warner Bros., Stardust and others. Client reviews highlight close integration between yellowHEAD’s UA creative team and ASO team, which matters for games where the same creative assets need to perform in both store listings and paid ad placements.
Best for: Established mobile game publishers that want ASO integrated with paid UA creative under one roof, with senior gaming-experienced ASO leadership and in-house creative production.
Udonis
Founded 2018 · 10 people · Osijek, Croatia · Mobile games only
Udonis is a mobile-games-exclusive marketing agency that has managed $500M+ in UA and creative budgets for game publishers including King, Voodoo, Socialpoint, and Tastypill.
ASO at Udonis is a supporting service within a primarily UA-and-creative-led engagement rather than a lead offering, which makes it relevant for this list but not a pure ASO specialist choice. The agency’s core strength is performance media buying and creative production (scripted ads, gameplay videos, UGC, playables), with ASO visual and text optimization offered to clients who also run paid UA with them. For studios looking specifically for ASO depth (dedicated ASO strategists, proprietary ASO tooling, specialized keyword research capabilities), Udonis is not the primary choice. For studios that want ASO assets produced by the same creative team making their UA ads, the integration is tight.
Best for: Mobile game studios that already have a UA-and-creative relationship with Udonis and want ASO store page assets produced alongside their paid ad creatives.
RadASO
Founded 2018 · 20+ people · London / Barcelona / New York · Apps & games
RadASO is a pure-play ASO and ASA specialist founded by Radomir Novkovich and part of the Netpeak Group since 2020. The agency has built proprietary tooling for keyword research automation and Apple Ads campaign management, and offers ASO, paid UA, localization, CRO, retention, and mobile analytics.
What differentiates RadASO is the Performance ASO pricing model, where clients pay based on measured install lift – a structurally unusual offer that signals confidence in measurement. Their references are heavily focused on smaller app clients with clear keyword and install-count outcomes, less so on marquee gaming brands. The agency runs an active ASO Busters Discord community, which is a useful signal of genuine ASO specialist engagement with the craft.
Best for: Apps and smaller game studios looking for a pure ASO/ASA specialist with performance-based pricing options and hands-on keyword research rigor, particularly for Eastern European, EU, and US markets.
Addict Mobile
Founded 2015 · ~50 people · Paris · Apps & games
Addict Mobile is a full-service performance marketing agency with a client base that skews more toward mobile gaming, particularly social casino and casual. It is included in this ASO guide because its store optimization work is connected to paid UA, creative production, and performance marketing for game publishers.
ASO at Addict is positioned as part of the broader performance stack rather than as a standalone specialist service: the agency’s value proposition is the integration between ASO, paid UA across major channels, and in-house creative production, supported by proprietary technology for campaign automation and attribution. This makes Addict a more natural fit for studios that want a single agency managing both sides of the acquisition equation than for publishers seeking deep ASO specialists. Strong gaming credentials, particularly in European markets.
Best for: Social casino, casual, and mid-core game studios that want ASO support connected to paid UA, creative production, and broader performance marketing rather than a pure-play ASO specialist.
Gummicube
Founded 2009 · 80 people · San Jose, California · Apps & games
Gummicube is one of the oldest dedicated ASO agencies in the industry. Co-founders Dave Bell and Anh Nguyen are credited with helping establish the ASO category itself.
The agency has its own proprietary technology stack: DATACUBE for market intelligence and keyword research across the App Store and Google Play, and Splitcube for A/B testing of store creatives and metadata.
On the gaming side, the published IMVU case study is a useful illustration of how Gummicube’s methodology plays out in practice. IMVU, an avatar-based social game, used DATACUBE to identify keyword themes beyond the obvious (“social networking,” “chat,” “virtual”) and specifically targeted game-based keywords the publisher had previously overlooked. The result was a move from #12 to #1 for “avatar game,” top position for “social games,” and top-five rankings for “chat games” and “virtual games,” followed by icon and screenshot conversion testing once the keyword work had done its job. Another long-running gaming engagement, the word puzzle game Pictoword, reportedly grew from 1,000 daily US downloads to 40,000 over the course of the partnership.
Best for: Enterprise apps and established game publishers that value proprietary data infrastructure, long-horizon ASO engagements, and a US-based specialist team with deep category tenure.
SplitMetrics Agency
Founded 2015 · 120+ across SplitMetrics group · Wilmington, Delaware (global team) · Apps & games
SplitMetrics Agency is the managed-services arm of SplitMetrics, the company behind SplitMetrics Acquire (formerly SearchAdsHQ, an Apple Ads optimization platform), SplitMetrics Optimize (an A/B testing platform for store listings), and App Radar (ASO tool). The agency offers fully managed Apple Ads, ASO services, and paid UA.
The agency is a natural fit for publishers who want managed Apple Ads delivered alongside ASO rather than treating the two as separate workstreams which is increasingly the right framing given how ASA and ASO conversion data feed each other.
The published Rockbite Games case study (on Deep Town: Mining Idle Tycoon, a sci-fi strategy game) is a clean illustration of the ASA-ASO synergy the agency sells. After testing the hypothesis that Apple Ads campaigns can lift organic rankings, SplitMetrics Agency took Deep Town from 26 keywords in the top 10 to 112, and grew the top 11-30 keyword pool from 81 to 161. In parallel, A/B testing of product page visuals through SplitMetrics Optimize lifted the game’s visibility score by up to 49% in target markets, with organic traffic growing by 30%+.
Other gaming-adjacent clients include Etermax and Prequel.
Best for: App and game publishers whose primary ASO question is closely tied to Apple Ads, keyword expansion, store listing tests, and organic visibility, and who want a technology-led service backed by proprietary automation.
AppTweak
Founded 2013 · 100+ people · Brussels (with SF, Bengaluru, Tokyo, Seoul offices) · Apps & games
AppTweak is primarily a leading ASO SaaS platform but it also operates a consulting services team that delivers hands-on ASO and Apple Search Ads work for clients that want managed execution on top of the tool.
The consulting arm offers ASO audits, keyword optimization, metadata writing, creative asset design, ASA campaign management, performance reporting, and in-house team training. The notable gaming clients are real: Electronic Arts, Jam City, Zynga, and multiple smaller publishers appear across AppTweak’s case studies and testimonials. The agency model is smaller and more bespoke than the pure-services agencies on this list. You’re buying access to the platform’s data quality and the team’s ability to operate it on your behalf, rather than a large delivery team. As an official Apple Ads Partner, AppTweak integrates ASA management into its service offering.
Best for: App and game publishers that want AppTweak’s data platform plus hands-on execution from the team that built it, particularly when deep keyword intelligence and Atlas AI-driven recommendations are the core requirement.
The ASO Project
Founded 2014 · 10 people · US-based · Apps & games
The ASO Project is a US-based ASO specialist offering fully managed ASO and Apple Search Ads services.
The agency has built proprietary tooling including its Search Ads Manager (SAM) platform for ASA bid management, keyword discovery, and automation, a Reviews Manager tool, and custom reporting dashboards.
Published client testimonials highlight multi-year engagements (Lose It! noted four years of work together), and the agency positions itself around full-service execution that includes in-house designers and video editors for creative asset production alongside the keyword and metadata work.
Service scope covers ASO strategy, Apple Search Ads management, Google UAC, creative production for store assets, and A/B testing. Less publicly known than Phiture or Gummicube, but consistently present on ASO-specific shortlists and with a track record of long client retention.
Best for: US-based apps and mid-sized game studios looking for a pure ASO specialist with fully integrated Apple Search Ads management and in-house creative production.
App Masters
Founded ~2013 · Small team · San Francisco Bay Area · Apps & games
App Masters, founded by Steve P. Young, is the smallest and most personality-driven agency on this list.
Steve is also the host of the long-running “App Marketing by App Masters” podcast and runs one of the most-followed app marketing YouTube channels. The agency’s service offering centers on ASO, Apple Search Ads, Google Ads, and growth strategy, and its real differentiator is the educational ecosystem Steve has built around it (App Masters Academy, the podcast, the YouTube channel).
For game studios, App Masters is not typically the right fit for large-budget campaigns, but it’s a credible option for indie developers, small game publishers, and teams that value education and hands-on advisory alongside execution.
Best for: Indie game developers, small studios, and early-stage app publishers looking for senior ASO expertise, educational partnership, and direct access to an experienced operator but not enterprise delivery.
How to Choose the Right ASO Agency for Your Mobile Game
Choosing an ASO agency for a mobile game is different from choosing a paid UA agency or a general app marketing partner. The right ASO partner needs to understand store listing conversion, metadata, game-specific creative assets, localization, experimentation, and how app store performance affects paid acquisition efficiency.
The four pillars below help filter out agencies that look credible on the surface but struggle to deliver real business impact once the engagement is underway.
1. ASO case studies that demonstrate true business impact
Any agency can show keyword ranking improvements, impression growth, or visibility lifts on a slide. Those metrics are useful, but they do not always translate into business impact. For mobile games, stronger ASO case studies should connect store listing changes to outcomes such as higher conversion rate, more installs from qualified traffic, better paid efficiency, lower effective CPI, stronger browse/search visibility, or improved performance across localized store pages.
When evaluating case studies, push past the headline ranking numbers and ask what happened after the store listing changed. Did conversion improve? Did paid UA become more efficient? Did the result hold after the first testing cycle? Agencies with genuine ASO impact are usually happy to explain the measurement logic.
2. Store creative capability that matches the game’s aesthetic and IP
This is the pillar most often underestimated. There are ASO agencies with strong methodology, deep experience, and credible frameworks whose art departments simply cannot match the quality bar of a mid-core or IP-driven game. Designers who don’t play games, don’t understand genre aesthetics, and can’t match the visual language of a notable IP (Warhammer, Marvel, Monopoly), or any brand with its own established look, will produce store assets that feel off. The result is frustrating for both sides: the client rejects asset after asset, the agency burns hours on revisions, and the relationship sours before any meaningful testing gets done. Before signing an engagement, look at the agency’s actual creative output for games in your category and with similar art styles. A portfolio full of productivity apps and fintech store pages is not a signal that the agency can execute on a fantasy RPG.
3. Integration with paid UA, creative strategy, and app store testing
In most cases, ASO should not be scoped as isolated store page optimization. The agencies that deliver the most value connect store assets with the broader acquisition system: top-performing paid ad concepts, custom product pages, in-app events, localization plans, and ongoing app store experiments.
For games, message match matters. The promise a player sees in a Meta, TikTok, Google, or Apple Search Ads campaign should carry through to the screenshots, preview video, and store listing they land on. Treating ASO as a separate workstream with a separate brief is how studios lose that compounding effect.
4. Clear ASO operating model
Before choosing an ASO agency, clarify what you actually need: keyword and metadata work, store creative production, experimentation strategy, localization, Apple Search Ads support, custom product pages, in-app events, or a full ASO testing program. Some agencies are strong strategic advisors, some are platform-led specialists, and some are best when ASO is connected to paid UA and creative production. The right fit depends on the exact bottleneck.
Get these four right and the agency selection mostly takes care of itself. Get any one of them wrong and even a well-regarded partner can turn into an expensive mistake.

FAQ: ASO Agencies for Mobile Games
An ASO agency for mobile games helps studios improve how their game appears and converts in the App Store and Google Play. This can include keyword research, metadata, icons, screenshots, preview videos, custom product pages, in-app events, localization, and app store experiments.
A user acquisition agency focuses on bringing paid traffic to the store page through channels such as Meta, Google, TikTok, Apple Search Ads, AppLovin, and other networks. An ASO agency focuses on improving what happens after users reach the store page: whether they understand the game, trust it, and install.
For many mobile games, ASO is less about generic app store search and more about conversion rate optimization. Better screenshots, icons, metadata, preview videos, and store experiments can improve the percentage of paid and organic visitors who install, which can lower effective CPI and improve paid UA efficiency.
A mobile game studio should consider hiring an ASO agency when store conversion is weak, paid UA efficiency is limited by low install rates, localization is underdeveloped, screenshots or icons need testing, or the team lacks a structured process for app store experiments.
