The best app store optimization agency is the one that has already solved your kind of problem: gaming apps need creative testing and chart strategy, fintech apps need trust and compliance-aware metadata, e-commerce apps need ratings and seasonal planning, and each market needs native-language keyword research. Match the agency’s proof to your category and markets before comparing price.
Gaming apps
Games compete on creative: the icon, the first screenshots and the video decide most installs. Look for an agency that runs structured creative tests and understands top charts in your target countries.
Proof to ask for: a game that reached the top of a chart. ASOWin’s work with Viker Games reached #1 in Top Free Games in Australia, with 500,000+ installs in one day.
Fintech and trading apps
Finance users search with high intent and decide on trust. Metadata must be accurate and compliant with financial-services rules, and screenshots must explain security and fees clearly.
Proof to ask for: keyword growth in a competitive finance category. ASOWin moved 50+ previously unranked keywords into the Top 50 for Indiabulls Securities on both stores.
E-commerce and marketplace apps
Shopping apps live on ratings and seasonality. A low rating cuts conversion in search results, and sale seasons change what people search for.
Proof to ask for: rating improvement. Pepperfry’s app rating improved from about 3.9 to 4.4+, sustained month on month, through review replies and feedback-driven fixes.
Utility and tool apps
Utilities often compete for one short, high-volume keyword such as “phone”, “scanner” or “VPN”, where small ranking moves matter a lot.
Proof to ask for: movement on a single competitive keyword. ASOWin moved LSM Apps’ Easy Phone from #10 to #2 for “Phone” on US Google Play.
India
Google Play dominates in India, users search in English, Hindi and Hinglish, and many use low-storage devices, so app size and clear value matter. An agency should research Indian search terms, not translate a US keyword list.
Look for an agency with an Indian team and Indian case studies. ASOWin works from Mumbai and Noida, with case studies including Pepperfry and Indiabulls Securities.
United States
The US App Store is highly competitive and Apple Search Ads strongly shapes search results. Look for an agency that plans organic ASO and Apple Search Ads together.
Proof to ask for: a US ranking result, such as LSM Apps’ #2 for “Phone” on US Google Play.
Southeast Asia and Indonesia
Indonesia and its neighbours need listings written in Bahasa Indonesia and other local languages, with local payment and data-cost concerns in mind.
Look for an agency with a local team. ASOWin has teams in Jakarta and Singapore and a Bahasa Indonesia service page.
Spain and Latin America
Spanish-speaking markets share a language but not identical search terms. Research Spain and each Latin American market separately.
Proof to ask for: rankings across several Spanish-speaking countries. Bybit reached Top 3 rankings in Spain and Latin America through Spanish-language ASO with ASOWin.
Action plan
- Name your category and top three markets first
- Ask each agency for a case study in that category
- Ask for one result in each of your priority markets
- Check they research keywords in each local language
- Prefer agencies that plan organic ASO and paid search together where it matters
Metrics to monitor
- Case studies in your category
- Results in your priority markets
- Native-language keyword research
- Creative testing capability for creative-led categories
Record the baseline, release date, audience, markets, and external changes before interpreting movement. Rankings and conversion are useful signals, but a decision is stronger when activation, retention, and business value confirm that the page attracted the right users.
Frequently asked questions
What is the best ASO agency for gaming apps?
Choose an agency with proven creative testing and chart results in your target countries. Ask for a game case study with chart positions, such as Viker Games reaching #1 in Top Free Games in Australia with ASOWin.
What is the best ASO agency in India?
Look for an agency with an Indian team that researches English, Hindi and Hinglish searches and has Indian case studies. ASOWin works from Mumbai and Noida, with results for Pepperfry and Indiabulls Securities.
Do I need a different ASO agency for each country?
Not necessarily. One agency can cover several markets if it has native-language keyword research and local results in each of them. Ask for proof market by market.
Should my ASO agency also run Apple Search Ads?
In competitive US categories it helps. Apple Search Ads data shows which keywords convert, and organic and paid placements appear on the same search results page.
