Keyword Research Methodology
Detailed reference for competitive keyword research across iOS App Store and Google Play Store.
Finding Competitors
Direct Search
Search the target store for the app's primary function:
- Type the most obvious search term (what a user would search)
- Note the top 10-15 results — these are the direct competitors
- Repeat with 3-5 variations of the search term
- Track which apps appear across multiple searches (strongest competitors)
Category Browsing
Browse the relevant category charts:
- iOS:
https://apps.apple.com/us/charts/iphone/{category-slug}/{category-id} - Google Play:
https://play.google.com/store/apps/category/{CATEGORY_ID}
Document apps ranked #1-25 in the target category.
Related Apps
On each competitor listing, scroll to "You Might Also Like" (iOS) or "Similar apps" (Google Play). These surface competitors that may not rank for the same keywords but compete for the same users.
Extraction Techniques
Title Keyword Extraction
For each competitor, break the title into individual keywords:
"Sleep Tracker - White Noise" → sleep, tracker, white, noise
"Calm Sleep: Meditation & More" → calm, sleep, meditation
Build a frequency table — keywords appearing in 3+ competitor titles are high-value targets.
Subtitle / Short Description Mining
Same process for subtitles (iOS) and short descriptions (Google Play). These often contain the secondary keywords the developer is targeting.
Description Keyword Density
For Google Play listings (where description is indexed):
- Copy the full description text
- Identify repeated terms (3+ occurrences)
- Note terms appearing in the first paragraph (highest weight)
- Look for keyword variations: "meditate", "meditation", "meditative"
Screenshot Caption Analysis
Competitor screenshot captions reveal keywords they consider important enough to show visually:
- Note exact phrases used in captions
- These often reflect the terms that convert best (tested by the competitor)
- Reuse the concept, not the exact copy
Search Suggestion Mining
App Store Search Suggestions
- Open the App Store search bar
- Type the first 2-3 letters of a target keyword
- Note all auto-suggested completions — these reflect real search volume
- Repeat for each primary keyword root
Google Play Auto-Complete
Same process in Google Play search. Google Play suggestions tend to be longer phrases (3-4 words), revealing long-tail opportunities.
Keyword Categorization Framework
Organize the master keyword list into categories:
| Category | Examples | Where to Use |
|---|---|---|
| Core | The app's primary function | Title, subtitle |
| Feature | Specific capabilities | Keywords field, description |
| Benefit | Outcomes the user gets | Subtitle, description |
| Audience | Who the app is for | Description, keywords |
| Alternative | Synonyms and related terms | Keywords field |
| Competitor | Competitor names (use carefully) | Keywords field only |
| Problem | What the user is trying to solve | Description |
Competitive Keyword Gap Analysis
Create a matrix showing which keywords each competitor targets:
| Keyword | App A | App B | App C | App D | Opportunity |
| ---------------- | ----- | ----- | ----- | ----- | ----------- |
| sleep tracker | Title | Title | Sub | — | Saturated |
| insomnia help | — | Desc | — | — | Low comp |
| sleep sounds | Sub | Title | Title | Sub | Moderate |
| bedtime routine | — | — | — | Desc | Open |
Keywords marked "Open" or "Low comp" are the highest-priority targets.
Character Budget Planning
Plan keyword allocation across available fields:
iOS Budget
| Field | Max Chars | Indexed? | Priority |
|---|---|---|---|
| App Name | 30 | Yes | Primary keyword |
| Subtitle | 30 | Yes | Secondary keywords |
| Keywords | 100 | Yes | All remaining terms |
| Description | 4000 | No | Conversion only |
Total searchable characters: 160
Google Play Budget
| Field | Max Chars | Indexed? | Priority |
|---|---|---|---|
| App Name | 30 | Yes | Primary keyword |
| Short Description | 80 | Yes | Secondary keywords |
| Full Description | 4000 | Yes | All keyword variations |
Total searchable characters: 4,110
Keyword Refresh Cadence
- Re-research keywords every 4-6 weeks after launch
- Monitor which keywords drive actual impressions (App Store Connect / Google Play Console analytics)
- Drop keywords with zero impressions after 2 update cycles
- Add trending terms from search suggestion mining
- Seasonal keywords (holiday, back-to-school, new-year) should rotate in/out on schedule
