Organic visibility in the App Store and Google Play is often shaped by the quality of an app’s keyword strategy, metadata, conversion rate optimization, and ongoing ranking analysis. For app publishers, selecting the right App Store Optimization partner can determine whether a product remains buried in search results or earns consistent installs from high-intent users.
TLDR: The best ASO agencies for keyword research and app ranking improvements combine data-driven keyword discovery, metadata optimization, creative testing, and performance tracking. Agencies such as Phiture, Gummicube, Moburst, App Radar, SplitMetrics Agency, and ConsultMyApp are frequently considered strong options for serious app growth. The ideal choice depends on an app’s category, budget, growth stage, localization needs, and whether the team requires strategy, execution, or both.
Why ASO Agencies Matter for App Ranking Growth
App Store Optimization is no longer limited to inserting a few popular keywords into an app title or description. Modern ASO requires deep market research, competitor tracking, keyword prioritization, review analysis, visual testing, localization, and conversion optimization. A skilled ASO agency studies how users search, how algorithms rank apps, and how store visitors decide whether to install.
For many companies, internal teams may understand the product well but lack specialized ASO tools, benchmarking data, or platform-specific expertise. An agency can provide external analysis, identify missed keyword opportunities, refine metadata, and test creative assets such as icons, screenshots, feature graphics, and preview videos.
What Makes an ASO Agency Strong for Keyword Research?
The best ASO agencies typically share several characteristics. They do not simply chase the highest-volume keywords. Instead, they balance search volume, ranking difficulty, relevance, conversion intent, and competitive positioning. A keyword that brings traffic but does not attract qualified users may weaken conversion rates and harm long-term performance.
Strong agencies also understand the differences between the Apple App Store and Google Play. Apple places heavy importance on fields such as the app name, subtitle, and keyword field, while Google Play analyzes app titles, short descriptions, long descriptions, and broader semantic relevance. A good agency adapts its approach to each store rather than applying the same metadata strategy everywhere.
Best ASO Agencies for Keyword Research and Ranking Improvements
1. Phiture
Phiture is widely recognized for its mobile growth expertise and structured ASO methodology. The agency works with apps across categories such as finance, health, education, entertainment, and subscription-based products. Its approach often combines keyword research, experimentation, retention insights, and lifecycle marketing.
Phiture is particularly suitable for teams that want ASO connected to broader mobile growth strategy. Rather than viewing rankings in isolation, the agency often considers how acquisition, activation, retention, and monetization interact. This makes it a strong fit for established apps seeking scalable improvements rather than one-time metadata updates.
Best for: Mature app teams, subscription apps, growth-focused companies, and brands needing advanced ASO strategy.
2. Gummicube
Gummicube is one of the longer-standing ASO agencies in the market and is known for its emphasis on app store intelligence and keyword data. The agency offers services that include keyword optimization, metadata development, conversion optimization, focus group testing, and app store creative improvements.
Its keyword research process is built around understanding actual app store search behavior rather than relying only on web search trends. This distinction matters because users often search differently in app stores than they do on traditional search engines. Gummicube is a strong choice for publishers that want dedicated ASO support backed by proprietary data and testing.
Best for: Apps needing specialized keyword research, metadata optimization, and conversion-focused app store testing.
3. Moburst
Moburst is a mobile marketing agency with ASO as one of its key service areas. It is often associated with app growth campaigns that combine organic optimization with paid user acquisition, creative production, influencer activity, and performance marketing.
For keyword research and ranking improvements, Moburst can be valuable because it looks at the full acquisition funnel. Paid campaign data may reveal which messages, audiences, and search terms convert best, while ASO research can strengthen organic rankings and store page conversion. This combined approach can help apps build stronger visibility in competitive categories.
Best for: Brands looking for ASO alongside paid acquisition, creative strategy, and broader mobile marketing campaigns.
4. App Radar
App Radar provides both ASO software and agency-style services, making it useful for teams that want a mix of platform access and expert support. Its services generally include keyword tracking, competitor analysis, metadata optimization, localization, and reporting.
App Radar may be especially helpful for companies that want transparency and workflow efficiency. The platform can support ongoing keyword monitoring, while experts help interpret the data and prioritize actions. For lean marketing teams, this combination can reduce manual research time and keep optimization work organized.

For keyword research, SplitMetrics can be useful when teams need to connect search visibility with store page performance. Ranking for stronger keywords matters, but those rankings become more valuable when the product page converts visitors into installers. The agency’s testing mindset can help identify which screenshots, messages, and value propositions improve install rates.
Best for: Apps that need experimentation, app store page testing, Apple Search Ads alignment, and conversion rate improvements.
6. ConsultMyApp
ConsultMyApp focuses on mobile app growth and works across ASO, customer engagement, retention, and user acquisition. Its ASO work often includes keyword research, competitor audits, localization, creative recommendations, and long-term performance monitoring.
This agency is a strong option for apps that want organic visibility improvements but also need help retaining and engaging users after install. Since improved rankings can increase download volume, a connected retention strategy helps ensure that additional users contribute to meaningful business outcomes.

8. The ASO Project
The ASO Project is a specialized agency focused on app store growth, metadata optimization, conversion rate optimization, and keyword performance. A specialist agency can be appealing for teams that want direct ASO expertise without broader advertising services taking priority.
For apps in competitive niches, a focused ASO partner can provide detailed keyword clustering, competitive gap analysis, and frequent iteration. This is useful because app rankings change constantly as competitors update metadata, receive reviews, launch campaigns, and localize into new markets.
Best for: Teams wanting dedicated ASO execution, keyword refinement, and ongoing ranking analysis.
How to Choose the Right ASO Agency
Selecting the best ASO agency depends on the app’s current stage and goals. A new app may need launch positioning, category research, and metadata setup. A growing app may need keyword expansion, localization, and systematic creative testing. A mature app may need advanced experiments, international growth, and deeper integration with paid acquisition.
- Review category experience: Agencies with experience in similar categories often understand relevant keyword patterns and user expectations faster.
- Ask about keyword methodology: A credible agency should explain how it evaluates volume, relevance, ranking difficulty, and conversion intent.
- Check reporting quality: Ranking improvements should be tracked alongside impressions, product page views, conversion rates, installs, and revenue signals.
- Evaluate localization skills: International ASO requires cultural understanding, not just direct translation.
- Look for experimentation: Agencies should test assumptions and iterate instead of relying on static recommendations.
Common ASO Services Offered by Top Agencies
Most leading ASO agencies offer a set of services designed to improve app visibility and conversion. These may include initial audits, keyword research, metadata writing, competitor benchmarking, localization, review analysis, creative testing, and performance reporting. Some agencies also support Apple Search Ads, paid acquisition, retention campaigns, and lifecycle messaging.
Keyword research remains central because it determines which search terms the app targets. However, ranking improvements usually require more than keyword placement. Agencies often improve screenshots, icons, videos, and descriptions to lift conversion rates. Higher conversion can indirectly support rankings because app stores tend to reward products that attract and satisfy users.
What Results Should App Teams Expect?
ASO is usually a medium- to long-term growth channel. Some metadata updates may influence rankings within days or weeks, but sustainable gains often require repeated testing and refinement. Competitive categories may take longer because many apps are targeting the same high-value search terms.
Reasonable goals include improved rankings for relevant keywords, higher organic impressions, better product page conversion rates, stronger localized performance, and increased organic installs. However, no reputable agency should guarantee a specific number-one ranking for a competitive keyword. App store algorithms are dynamic, and performance depends on many factors, including reviews, ratings, retention, downloads, and competitor activity.
Final Thoughts
The best ASO agencies for keyword research and app ranking improvements are those that combine technical store knowledge with practical growth strategy. Phiture, Gummicube, Moburst, App Radar, SplitMetrics Agency, ConsultMyApp, Yodel Mobile, and The ASO Project each offer different strengths depending on the app’s needs.
For app publishers, the smartest choice is not always the largest or most recognizable agency. The best partner is the one that understands the app’s market, communicates clearly, tests continuously, and ties keyword rankings to real business outcomes. When ASO is handled strategically, it can become one of the most efficient and durable channels for app growth.
