How to Do Keyword Research for App Store Optimization (ASO)

Keyword research is the foundation of App Store Optimization.

If you choose the wrong keywords, everything else—title, description, screenshots, even ads—works harder than it should.
If you choose the right ones, your app can grow steadily without relying only on paid installs.

This guide explains how to do keyword research for App Store Optimization, step by step, in a practical and realistic way. No fluff. No shortcuts. Just what actually works.

Why Keyword Research Matters in ASO

Every install that comes from search starts with a keyword.

When users type something into the App Store or Google Play, the store decides which apps are most relevant. Your rankings depend largely on how well your app matches those searches.

Good keyword research helps you:

• Get discovered by the right users

• Rank faster, especially as a new app

• Improve conversion and retention

• Avoid wasting time on keywords you can’t win

ASO without keyword research is guesswork.

Step 1: Understand Search Intent First (Not Tools)

Before opening any ASO tool, understand why users search.

Ask:

• What problem are they trying to solve?

• Are they looking for a feature, a solution, or an alternative?

• Are they beginners or advanced users?

For example:

• “habit tracker” → general intent, high competition

• “habit tracker for ADHD” → specific intent, lower competition

Specific intent usually converts better and ranks faster.

Step 2: Start With Seed Keywords

Seed keywords are the base terms that describe your app.

Write down:

• Your core function

• Main features

• Use cases

• Target audience terms

Example for a finance app:

• expense tracker

• budget planner

• money management

• personal finance app

This list doesn’t need to be perfect. It just needs to reflect what your app actually does.

Step 3: Use App Store Auto-Suggestions

One of the most underrated keyword sources is the app store itself.

Go to the App Store or Google Play and:

• Type a seed keyword

• Note the suggested phrases

• Add letters (a–z) after the keyword

• Look for repeated patterns

These suggestions come from real user searches, which makes them extremely valuable.

If users are searching for it, it’s worth analyzing.

Step 4: Analyze Competitor Keywords

Competitor research saves time and reduces guesswork.

Look at:

• App titles

• Subtitles (iOS)

• Short descriptions (Google Play)

• Repeated words across top apps

Questions to ask:

• Which keywords appear in multiple top apps?

• Are they ranking because of brand strength or keyword relevance?

• Can your app realistically compete?

Don’t blindly copy competitors. Use them to understand what the market values.

Step 5: Use ASO Tools (The Right Way)

ASO tools help you validate ideas—not generate strategy.

Useful metrics to check:

• Search volume

• Difficulty / competition

• Relevance

• Trends over time

What to prioritize:

• Medium or low competition keywords

• Keywords that clearly match your app

• Phrases users would install for

Avoid:

• Chasing the highest volume keywords

• Choosing keywords just because tools recommend them

A keyword with lower volume but high intent often performs better.

Step 6: Build a Balanced Keyword List

A strong ASO keyword list includes:

1. Primary keywords

   • Core terms describing your app

   • Used in title or main metadata

2. Secondary keywords

   • Variations and supporting terms

   • Used in subtitle, description, keyword field

3. Long-tail keywords

   • More specific phrases

   • Easier to rank, higher conversion

This balance helps new apps gain traction faster.

Step 7: Map Keywords to Metadata Fields

Keyword placement matters as much as keyword choice.

iOS (Apple App Store)

• App title → highest weight

• Subtitle → strong ranking impact

• Keyword field → hidden but important

Avoid repeating the same keyword across fields. iOS combines them automatically.

Google Play

• Title and short description matter most

• Long description supports indexing

• Keyword repetition should feel natural

Over-optimization hurts more than it helps.

Step 8: Localize Keyword Research (If Possible)

Search behavior changes by country.

A keyword that works in the US may not work in:

• India

• Germany

• Japan

If you’re targeting multiple regions:

• Research keywords per locale

• Translate intent, not just words

• Prioritize top markets first

Even basic localization can unlock extra organic installs.

Step 9: Track and Refine After Publishing

Keyword research doesn’t end after publishing.

Track:

• Keyword impressions

• Ranking changes

• Conversion rates

• Review language

Look for:

• Keywords gaining impressions but not installs → conversion issue

• Keywords ranking low but relevant → optimization opportunity

Refining keywords every few weeks usually delivers better results than large one-time changes.

Common Keyword Research Mistakes in ASO

• Targeting only high-volume keywords

• Ignoring relevance

• Copying competitors blindly

• Repeating keywords unnecessarily

• Never updating keyword strategy

Most ASO failures come from these mistakes, not from lack of effort.

Practical Advice From Real ASO Work

• Start with fewer keywords, not more

• Focus on clarity before creativity

• Think like a user, not a marketer

• Use review language to find new keyword ideas

• Be patient—keyword rankings take time

Apps that grow steadily usually follow these basics consistently.

Final Takeaway

So, how do you do keyword research for App Store Optimization?

You:

• Understand user intent

• Start with realistic keywords

• Validate with data

• Place them correctly

• Improve over time

ASO keyword research isn’t about finding “perfect” keywords.
It’s about finding relevant, winnable keywords and building momentum step by step.

Do this well, and organic installs stop being unpredictable—they become repeatable.
