Choosing an App Store Optimization agency can be challenging when different companies offer similar services but take very different approaches to ASO. The right partner should understand how app stores evaluate and rank apps, while also connecting keyword optimization, metadata, localization, and creative testing to your acquisition goals.
A strong ASO strategy goes beyond adding keywords to an app listing. It can involve researching search behavior, optimizing titles and descriptions, testing visual assets, improving conversion rates, and adapting listings to different markets. The scope you need depends on your app, target audience, and growth stage.
This guide covers how to choose an App Store Optimization agency and compares companies that offer comprehensive services. We look at their expertise, services, pricing, and other factors that can help you assess which agency fits your app’s needs.
What Is an App Store Optimization Agency?
An App Store Optimization (ASO) agency is a company that helps improve an app’s visibility and conversion in app stores. It typically works on keyword research, metadata, creative assets, localization, and testing to help apps attract more relevant organic traffic and downloads.
How Is ASO Different From App Marketing?
ASO focuses specifically on improving an app’s performance within app stores, while app marketing covers a wider range of acquisition and retention channels. ASO can support app marketing by increasing organic discovery and helping turn store visitors into downloads.
| Aspect | ASO | App Marketing |
| Main focus | App store visibility and conversion | User acquisition and retention across channels |
| Key channels | App Store and Google Play | Paid ads, social media, email, influencers, ASO, and more |
| Optimization | Keywords, metadata, visuals, and listings | Campaigns, audiences, creatives, and user journeys |
| Primary goal | More relevant organic traffic and downloads | Broader app growth and user acquisition |
What Can an ASO Agency Do for Your App?
An ASO agency can turn app store optimization into an ongoing growth process rather than a one-time listing update. It can help establish a clear optimization strategy, identify areas with growth potential, and adapt the approach as the app, market, and competitive landscape change.
- Build an ASO roadmap around the app’s growth objectives.
- Assess the current store presence and identify optimization opportunities.
- Use market and competitor insights to guide optimization priorities.
- Coordinate optimization efforts across different target markets.
- Establish a testing cycle instead of relying on one-off changes.
- Evaluate results and adjust the strategy as performance data accumulates.
- Keep ASO efforts aligned with changes in app store algorithms and market trends.
A professional agency provides an ongoing framework for improving how an app is discovered and evaluated in the stores, with decisions guided by testing and performance data.
Which ASO Services Can You Outsource to an Agency?
ASO agencies can take responsibility for the parts of app store optimization that require ongoing research, testing, and iteration. Depending on the app and target markets, an agency may provide services such as:
| Service | What It Includes |
| ASO keyword research | Finding relevant search terms, assessing competition, and building a keyword strategy. |
| App store listing optimization | Refining titles, subtitles, descriptions, and metadata to improve discoverability. |
| Creative ASO | Testing and optimizing icons, screenshots, app previews, and other visual elements. |
| App localization | Adapting store listings and creatives to different languages, markets, and local search behavior. |
| A/B testing | Comparing listing elements to identify changes that can improve conversion rates. |
| Competitor analysis | Tracking competing apps, their rankings, keywords, listings, and creative approaches. |
| ASO performance monitoring | Measuring keyword rankings, visibility, conversion metrics, and the impact of optimization work. |
The scope can range from a one-time store audit to continuous ASO management. Agencies may also combine several services into an ongoing optimization program based on the app’s growth stage and target markets.
What Should You Know Before Hiring an ASO Company?
Before choosing an ASO agency, define what you want to improve and which markets or app stores matter most to your growth plans. This gives you a clearer basis for assessing whether an agency’s approach matches your app’s needs.
It’s also worth looking beyond the list of ASO services. Consider the agency’s experience with apps similar to yours, how it approaches research and testing, how it measures progress, and whether its recommendations are backed by performance data.
Finally, clarify how the partnership will work before signing. Discuss the scope of work, pricing, reporting, communication, expected timelines, and who will be responsible for implementing changes in the app stores.
How Are ASO Agency Services Priced?
ASO agency services typically cost around 1,500–15,000+ per month, depending on the agency, app portfolio, target markets, and scope of work. One-time audits and strategy projects can cost less, while ongoing work covering multiple markets, creative testing, and broader app growth support tends to sit at the higher end.
What Should an ASO Agency Include in Its Proposal?
An ASO proposal should give you a clear picture of how the agency plans to improve your app’s store performance and how the work will be measured. Before signing, check that it covers:
- Current ASO audit and key areas for improvement.
- Proposed strategy and optimization priorities.
- Scope of work and specific deliverables.
- Target app stores, markets, and languages.
- Testing and optimization process.
- Timeline and expected milestones.
- Pricing and payment terms.
- KPIs, reporting format, and review frequency.
- Roles, responsibilities, and communication process.
How to Choose an ASO Agency
Choosing an ASO agency is not just about improving rankings in the App Store or Google Play. The right partner should understand how visibility, conversion, and app growth work together.
✅ ASO-specific expertise
Look for agencies with proven experience in app store optimization, not just broader SEO or digital marketing.
✅ Strong conversion focus
A good ASO partner should think beyond keywords and rankings. Listing visuals, screenshots, preview videos, and copy all affect install rates.
✅ Data-driven testing
The agency should have a clear process for testing metadata, creatives, and conversion drivers over time.
✅ Platform knowledge
A strong team should understand the differences between Apple App Store and Google Play, including how discovery and ranking factors vary.
✅ Relevant proof of results
Prioritize agencies that can show ASO case studies, explain what they changed, and point to measurable growth in visibility, installs, or conversion.
The best ASO agencies do more than improve discoverability. They help apps attract the right users and turn store traffic into sustainable growth.
Questions to Ask Before Hiring an ASO Agency
Once you have shortlisted a few agencies, the next step is to understand how they actually work.
| Question | Why ask it | What a strong answer looks like |
| Have you worked with apps similar to ours before? | This shows whether the agency understands your category and growth challenges. | They can point to relevant apps, explain the strategy, and describe the outcomes. |
| How do you approach ASO on the App Store versus Google Play? | The two platforms work differently, so strategy should not be identical. | They explain how metadata, visuals, testing, and optimization differ by platform. |
| How do you measure success beyond rankings? | Rankings alone do not show full business impact. | They talk about installs, conversion rate, retention signals, or growth in organic acquisition. |
| How do you handle testing and iteration? | ASO is not a one-time setup. | They explain how they test keywords, creatives, and conversion elements over time. |
| Can you share relevant case studies? | This helps separate real experience from general claims. | They provide examples with clear context, execution details, and measurable results. |
| What does reporting and communication look like? | Clear visibility matters when optimization is ongoing. | They explain reporting cadence, ownership, and the KPIs they track regularly. |
These questions help you evaluate not only what an agency promises, but how it thinks, tests, and supports app growth in practice.
Red Flags to Watch for When Hiring an ASO Company
Choosing an ASO agency requires looking beyond its service list and app store expertise. Watch for these warning signs before entering into a partnership:
- 🚩 Guarantees specific ranking or download results without explaining the conditions behind them.
- 🚩 Treats ASO as a one-time metadata update instead of an ongoing process.
- 🚩 Cannot explain how it will measure and improve app store performance.
- 🚩 Has no relevant case studies or verifiable ASO experience.
- 🚩 Uses the same optimization approach for every app and market.
- 🚩 Makes recommendations without showing the research behind them.
- 🚩 Provides vague reporting with no clear connection between its work and results.
- 🚩 Offers unclear pricing or leaves the scope of ongoing work undefined.
These signs do not automatically indicate that an agency is unsuitable. They simply highlight areas worth exploring before you commit. A credible ASO partner should be clear about its methodology, deliverables, reporting, pricing, and what it can realistically influence.
Common Mistakes When Choosing an ASO Agency
Choosing an ASO agency involves more than comparing service lists and prices. Some common mistakes can lead to the wrong expectations, ineffective optimization, or wasted budget. Knowing what to watch for can help you evaluate agencies more critically before making a decision.
❌ Hiring a general digital agency with weak ASO experience
ASO requires platform-specific knowledge that goes beyond standard SEO or paid media.
❌ Focusing only on rankings
Higher rankings can help, but they do not automatically lead to more installs if conversion is weak.
❌ Ignoring creative optimization
Screenshots, icons, preview videos, and store copy all influence conversion and should not be treated as secondary.
❌ Expecting one-time setup to be enough
ASO usually performs best as an ongoing process with regular testing and iteration.
❌ Trusting vague claims without proof
A strong agency should be able to explain its process and show relevant examples.
❌ Starting without clear goals
It should be clear whether the priority is visibility, install growth, conversion improvement, market expansion, or broader app growth.
Avoiding these mistakes can save budget and make it easier to choose a partner that fits your app’s actual needs.
ASO Agency, In-House Team, or Freelancer: Which Should You Choose?
There are several ways to handle app store optimization, and each model comes with a different level of expertise, control, and resource commitment. An agency can provide a broader ASO function, an in-house team keeps the work within the company, while a freelancer can be a practical option for more focused needs.
| ASO Agency | In-House Team | Freelancer | |
| Expertise | Access to multiple ASO specialists and supporting expertise | Built around the skills of internal employees | Usually centered on one specialist’s experience |
| Cost structure | Usually a monthly retainer or project fee | Salaries plus hiring, tools, and training costs | Often charged by the hour or project |
| Flexibility | Can adjust the scope as ASO needs evolve | Changes may require new roles or resources | Easy to engage for a defined task or period |
| Control | Strategy and execution are shared with an external partner | Full control over ASO operations | Direct control over the assigned work |
| Resources | Agency brings established processes, tools, and team capacity | Business must build and maintain its own ASO setup | Resources depend largely on the individual specialist |
| Best suited for | Apps that need ongoing ASO expertise and a wider range of support | Companies with the resources to maintain ASO internally | Businesses needing specialized help with specific ASO tasks |
The best setup depends on how much ASO work your app requires and what resources you already have. An agency offers a broader team structure, an in-house model provides deeper internal ownership, and a freelancer can provide targeted expertise without a long-term team commitment.
