## Keyword Research Methodology

### Phase 1: Seed Keyword Generation

Start by generating initial keyword ideas from multiple sources.

**Source 1: Core App Functions**

List every action or problem the app solves:

```
Example for a task management app:
- Create tasks
- Set reminders
- Track deadlines
- Organize projects
- Collaborate with team
- Plan daily schedule
```

**Source 2: User Language Mapping**

Match developer terminology to user searches:

| Developer Term | User Search Terms |
|----------------|-------------------|
| Task management | todo list, task app, tasks |
| Project organization | project planner, project tracker |
| Deadline tracking | due date reminder, deadline app |
| Time blocking | schedule planner, calendar app |
| GTD methodology | getting things done, productivity system |

**Source 3: App Store Autocomplete**

Type seed keywords into App Store/Play Store search and record suggestions:

```
"todo" → todo list, todo app, todo list app, todolist widget
"task" → task manager, task planner, task list, tasks to do
"remind" → reminder app, reminder, reminders widget, remind me
```

**Source 4: Competitor Analysis**

Extract keywords from top 10 competitors in category (detailed in section below).

### Phase 2: Keyword Expansion

**Expansion Techniques:**

| Technique | Example (seed: "todo") |
|-----------|------------------------|
| Add modifiers | free todo, best todo, simple todo |
| Add actions | make todo list, create todo, organize todo |
| Add platforms | todo app iphone, todo for mac, todo widget |
| Add audiences | todo for students, business todo, family todo |
| Add features | todo with reminders, todo calendar, todo sync |
| Add problems | forgot tasks todo, procrastination todo |

**Keyword Matrix Template:**

| Core Term | Modifier 1 | Modifier 2 | Full Keyword |
|-----------|------------|------------|--------------|
| todo | free | app | free todo app |
| todo | best | iphone | best todo iphone |
| task | manager | simple | simple task manager |
| reminder | daily | widget | daily reminder widget |
| planner | weekly | calendar | weekly planner calendar |

### Phase 3: Keyword Filtering

Remove irrelevant or low-quality keywords:

**Exclusion Criteria:**

| Criterion | Reason | Example |
|-----------|--------|---------|
| Competitor brand names | Policy violation | "todoist alternative" |
| Unrelated categories | Low conversion | "todo games" |
| Plural duplicates (iOS) | Wasted space | "tasks" when "task" exists |
| Single characters | No search value | "to do" vs "todo" |

## Keyword Evaluation Framework

### Keyword Scoring Model

Evaluate each keyword on four dimensions:

**1. Search Volume (0-100)**

| Volume Level | Score | Monthly Searches |
|--------------|-------|------------------|
| Very High | 80-100 | 50,000+ |
| High | 60-79 | 10,000-49,999 |
| Medium | 40-59 | 1,000-9,999 |
| Low | 20-39 | 100-999 |
| Very Low | 0-19 | <100 |

**2. Competition (0-100, inverted)**

| Competition | Score | Top 10 App Ratings |
|-------------|-------|-------------------|
| Very Low | 80-100 | Average <4.0 stars |
| Low | 60-79 | Average 4.0-4.2 stars |
| Medium | 40-59 | Average 4.3-4.5 stars |
| High | 20-39 | Average 4.6-4.8 stars |
| Very High | 0-19 | Average 4.9+ stars |

**3. Relevance (0-100)**

| Relevance | Score | Criteria |
|-----------|-------|----------|
| Exact Match | 90-100 | Keyword describes core function |
| Strong Match | 70-89 | Keyword describes major feature |
| Moderate Match | 50-69 | Keyword describes secondary feature |
| Weak Match | 30-49 | Keyword tangentially related |
| No Match | 0-29 | Keyword unrelated to app |

**4. Conversion Potential (0-100)**

| Intent | Score | User Query Type |
|--------|-------|-----------------|
| Transactional | 80-100 | "best [app type]", "[app type] app" |
| Commercial | 60-79 | "free [app type]", "[app type] for [use]" |
| Informational | 40-59 | "how to [action]", "what is [concept]" |
| Navigational | 20-39 | "[brand name]", "[specific app]" |

### Composite Score Calculation

```
Keyword Score = (Volume × 0.25) + (Competition × 0.25) +
                (Relevance × 0.35) + (Conversion × 0.15)
```

**Score Interpretation:**

| Score Range | Priority | Action |
|-------------|----------|--------|
| 80-100 | Primary | Target in title and keyword field |
| 60-79 | Secondary | Include in subtitle/description |
| 40-59 | Tertiary | Use in long description only |
| 0-39 | Deprioritize | Do not target |
