Quick answer: How do I become an app store optimization specialist?
- Search drives installs — Apple says about 65% of App Store downloads happen directly after a search.
- Two stores, two rulebooks — App Store keyword field vs Google Play's full-description indexing.
- What's tested — keywords, metadata, creatives, experiments, ratings and reporting.
- Where ASO sits — app marketing, user acquisition and mobile growth teams.
- Proof — a listing you optimised with before/after conversion data.
Key takeaways
- ASO is search optimisation plus conversion optimisation for store pages.
- Each store has different metadata rules — know them precisely.
- Screenshots and the first lines of copy do most of the converting.
- Test creatives with the stores' own experiment tools.
- Ratings and reviews affect both ranking signals and conversion.
Picture two candidates for an ASO role at a fitness app. Both rewrite the store listing. The first stuffs the title with every keyword they can find, and Google Play flags the listing under its metadata policy. The second researches keywords separately for each store, then rewrites the App Store title, subtitle and hidden keyword field within Apple's limits and the Play description in plain, natural language. She briefs three screenshot concepts led by the app's actual outcome ("Your 20-minute home workout plan") and runs a store listing experiment on Play. The winning set lifts store conversion, and she shows the before-and-after numbers in her interview. She gets the offer.

What ASO specialists do
App store optimization (ASO) is improving an app's visibility in App Store and Google Play search and browse, and its conversion from store visit to install. Titles include ASO specialist, app marketing manager, mobile growth manager and user acquisition manager.
The stakes are high because the stores are where most people find apps. Apple has long said about 65% of App Store downloads happen directly after a search, a figure it still cites in its ads materials.1 Each store has its own rules: on the App Store, the app name and subtitle are limited to 30 characters each and a separate 100-character keyword field is indexed;23 Google Play indexes the title and descriptions and prohibits keyword stuffing and misleading metadata under its policy.4 Apple's own guidance explains that search uses text relevance and user behaviour such as downloads and ratings.5

How ASO candidates are assessed
| Stage | What happens | What they check |
|---|---|---|
| Listing audit | "Critique our store page" | Metadata, creatives, ratings |
| Keyword task | "Find 20 keywords and prioritise them" | Relevance, volume, difficulty |
| Creative brief | "Brief new screenshots" | Benefit-led messaging |
| Analytics | "Conversion dropped 15%. Why?" | Store analytics fluency |
| Experiment design | "Test a new icon" | Test setup and reading results |
Table: How ASO roles are assessed (editorial summary)
What hiring managers screen for

Keyword research
Relevance, search popularity, competition and intent — per store and per country.
Metadata
Titles, subtitles, keyword fields and descriptions written within each store's rules.
Creative optimisation
Icons, screenshots and preview videos that lead with outcomes, not features.
Experiments
Google Play store listing experiments and App Store product page optimisation tests.
Ratings and reviews
Prompting at good moments, responding to reviews and feeding issues to product.
Reporting
Impressions, product page views, conversion rate, installs and keyword rankings by store.
Worked example: App Store metadata
App name (≤30): FitHome: 20-Min Workouts
Subtitle (≤30): Home training plans, no gym
Keyword field (≤100, comma-separated, no spaces, no repeats of name words):
hiit,yoga,abs,beginner,fat,burn,strength,stretch,cardio,pilates,women,men,timer
Screenshots 1–3: "Your 20-minute plan" • "No equipment needed" • "Track every streak"
Why it works: each field is within its limit, the keyword field avoids repeating words already in the name and subtitle, and the first screenshots sell outcomes in a few words. On Google Play, the same intent would go into a natural, readable description rather than a keyword list.
How ASO has changed
| Period | What happened | What employers wanted |
|---|---|---|
| 2008–2012 | App stores launch and grow | Getting listed and noticed |
| 2013–2016 | Keyword tactics mature; Apple Search Ads launches | Keyword specialists |
| 2017–2020 | Store redesigns; Play experiments; in-app events | Creative testing |
| 2021–2024 | Custom product pages; privacy changes hit paid UA | ASO as a growth lever |
| 2025–2027 | AI-assisted creative; more search ad placements | Integrated organic and paid store growth |

ASO interview questions, with how to answer them
"How do App Store and Google Play differ for ASO?"
The App Store uses a dedicated keyword field with strict limits; Google Play indexes the descriptions and penalises stuffing. Experiment tools and ranking signals differ too.
"Conversion dropped. How do you investigate?"
Check traffic source mix, new competitors, rating changes, creative or metadata changes, seasonality and store feature changes.
"How do you choose keywords?"
Relevance first, then popularity and difficulty, with intent matching what the app actually does.
"How do you improve ratings?"
Fix the issues reviews mention, ask for ratings at positive moments using the platforms' rating prompts, and reply to reviews.
"How do you test screenshots?"
One clear hypothesis per test, using the store's tools, run long enough to get a reliable result.
Could you pass the App Store Optimization (ASO) Certification today?
Hiring managers test judgement with scenarios like this one. Answer it before you open the explanation — the certification has 20 of them, 30 minutes, 75% to pass.
Your app's subtitle is "The best app ever made". What's a better use of those 30 characters?
- A clear benefit with a key search term, such as "Budget planner & bill tracker"
- Your company's legal name
- A list of emojis
- The same words as the app name
Show the answer
A. A clear benefit with a key search term, such as "Budget planner & bill tracker" — The subtitle is indexed for search and shown in results. A specific benefit with a relevant keyword helps both ranking and conversion.

- No before/after numbers.
Your first 90 days in an ASO role
| Period | Focus | What good looks like |
|---|---|---|
| Days 1–30 | Audit both stores: metadata, creatives, ratings, analytics | A baseline of impressions, conversion and rankings |
| Days 31–60 | Ship a keyword and metadata update per store | Ranking movement on priority keywords |
| Days 61–90 | Run creative experiments and a ratings plan | Measured lift in store conversion |
Table: A first-90-days plan (editorial guidance)
Start every ASO role with a careful audit, because store analytics hide easy wins. Check which countries and traffic sources bring impressions, where conversion is weakest, how ratings have trended, and how your listing compares with the top competitors for your main keywords. Then make one well-reasoned metadata update per store — separately, because their rules and ranking signals differ — and track rankings for a few weeks before changing anything else, so you can attribute movement. With search visibility moving, turn to conversion: test benefit-led screenshots, a clearer icon or a shorter video, one hypothesis at a time, using the stores' own experiment tools. Alongside, work with the product team on rating prompts at good moments and replies to recent reviews. By the end of the quarter you should be able to show a clean before-and-after story with numbers, which is the strongest evidence for an app marketing or mobile growth role.

Frequently asked questions
What does an ASO specialist do?
An ASO specialist increases an app's visibility and conversion in the App Store and Google Play: researching keywords, writing titles, subtitles and descriptions within each store's rules, designing and testing screenshots and videos, managing ratings and reviews, localising listings and reporting on impressions, page views, conversion and installs.
How is ASO different from SEO?
Both optimise for search, but app stores have their own metadata fields, character limits, ranking signals and conversion-focused pages. ASO also leans heavily on creative testing, ratings and in-store features.
What tools do ASO specialists use?
App Store Connect and Google Play Console analytics and experiments, keyword research and rank-tracking tools, review management tools, and design tools for screenshots. Employers care more about method than any single tool.
How long does ASO take to show results?
Metadata changes can affect rankings within days to weeks, depending on the store and update review. Creative tests need enough traffic to reach a reliable result, which can take one to several weeks.
Do ASO specialists need design skills?
Not necessarily, but you need strong creative judgement and the ability to brief designers on screenshots, icons and preview videos, then test them properly.
What's a good first ASO project?
Optimise a real app — your own, a friend's or a small business's — with keyword research, a rewritten listing and a creative test. Document impressions, conversion and installs before and after.
