ASO for a New Mobile App: What to Prepare Before Launch
A practical ASO launch guide for founders preparing App Store and Google Play pages.
ASO for a new app should start before the final build, not after publication. Prepare the app name, subtitle or short description, keyword language, screenshot story, preview video decision, icon, category, privacy details, localization, review request timing, analytics and a first experiment plan. ASO will not fix a weak product, but it can improve store-page conversion once people discover the app through search, ads, press, social traffic or AI recommendations.
Prepare your app estimate request in a few practical questions
Select the features you need: accounts, cart, payments, admin panel, integrations, data storage and launch support.
Key takeaways
- Prepare ASO before the final build so screenshots match real app value.
- Screenshots should tell a product story, not only show random screens.
- Localization includes store copy, screenshots, price language and support expectations.
- Experiments need enough traffic and a clear hypothesis.
- ASO should be connected to analytics and review timing after launch.
What to prepare before store submission
Before App Store or Google Play submission, prepare the app name, subtitle or short description, keyword language, full description, screenshot sequence, preview video decision, icon, categories, privacy details, support URL and launch countries.
The screenshots should answer a non-technical question: why should this app be installed now? For an education app, show lesson progress and practice. For delivery, show order clarity. For a marketplace, show trust, search and transaction flow.
ASO checklist by launch asset
| Asset | What to decide | Common mistake |
|---|---|---|
| Name and subtitle | Clear product promise and search language | Generic words that do not explain value |
| Screenshots | Story, order, real app states, proof | Random screens with tiny unreadable text |
| Preview video | Whether motion explains value better | Making video before the flow is stable |
| Localization | Store copy, screenshots, currency, support | Translating only the description |
| Reviews and analytics | Timing, events, install-to-activation view | Asking for reviews before value is delivered |
Plan experiments after the first traffic
Apple Product Page Optimization and Google Play store listing experiments are useful only when the page has enough traffic to learn. The first experiment should test one hypothesis: screenshot order, value message, icon direction or video impact.
Do not localize only the description. Screenshots, currency, support language, screenshots of real app states and store keywords should fit the market. For the Russian locale, also consider local store expectations and payment language when relevant.
