How to Do ASO Keyword Research from App Reviews

Most app store optimization starts with a keyword tool that shows search volume and difficulty. That is useful, but it misses something: the exact words real users use to describe your app, its benefits, and its problems. App reviews are a free, continuously updated corpus of that language - the phrases people actually type when they search. By exporting reviews and analyzing word frequency, you can find high-intent keywords your competitors miss and write a listing that matches how users really talk. Here is the full workflow.

Step 1: Export Reviews for Your App and Top Competitors

Use the Google Play Reviews Exporter to download reviews for your app and three or four close competitors into CSV. Including competitors is important - it reveals the vocabulary of users who chose a rival, surfacing keywords you may not rank for yet. If you are new to the export step, our Google Play export guide covers it in detail.

Step 2: Build a Word and Phrase Frequency List

Open the combined CSV and count how often words and two-to-three word phrases appear in the review text. A pivot table or a simple spreadsheet formula is enough to start. You are looking for recurring nouns and verbs that describe what the app does and the jobs users hire it for.

• Feature words: "offline mode", "dark theme", "widget", "sync"
• Benefit words: "save time", "track habits", "stay focused"
• Category words: how users name the app's category in their own terms

Our guide on analyzing exported reviews in Excel and Google Sheets shows the exact pivot-table technique for this.

Step 3: Separate Positive and Negative Language

Split your frequency analysis by star rating. High-rating reviews tell you which benefits to lead with in your title and subtitle - the language that already resonates. Low-rating reviews reveal objections to address in your description and the keywords competitors are losing on. For a faster pass, the optional AI analytics layer can score sentiment and cluster themes automatically.

Step 4: Map Keywords to Listing Fields

Take your highest-frequency, highest-intent terms and place them where they carry the most weight: the app title and subtitle for your strongest keyword, the short description for primary benefits, and the long description for secondary and long-tail phrases. Write in the users' own words rather than internal jargon - that alignment is what lifts both ranking and conversion.

What This Workflow Unlocks

Untapped Keywords

Find terms users search for that your current listing never mentions - the cheapest ranking gains in ASO.

Competitor Gaps

Spot complaints in competitor reviews and target the keywords of users actively looking to switch.

Higher Conversion

Listings that echo user language convert better because they confirm exactly what the visitor came to find.

Continuous Refresh

Re-export quarterly to catch new vocabulary as your category and user base evolve.

Frequently Asked Questions

Why use app reviews for ASO keyword research?

Reviews contain the exact language users use to describe your app and the problems it solves. That real-world vocabulary often matches search behavior more closely than generic keyword tools, helping you rank for terms competitors overlook.

How many reviews do I need for useful keyword data?

A few hundred reviews per app is usually enough to see clear frequency patterns. The more you export across your app and competitors, the more reliable the high-frequency terms become.

Do I need special tools to analyze the keywords?

No. A spreadsheet pivot table handles word and phrase frequency. For automatic sentiment and theme clustering, the optional AI analytics layer speeds things up, but it is not required.

Can I do this for competitor apps too?

Yes, and you should. The Google Play exporter works on any public app page, so you can mine competitor reviews to find keywords their dissatisfied users are searching for.
