Assessing Your Coverage​

Coverage Audit Process​

Step 1: Map Existing Content

Create inventory of current content:

  • List all articles by topic
  • Identify main themes
  • Note content depth
  • Map relationships

Step 2: Identify Topic Boundaries

Define scope:

  • Core topic definition

  • Out-of-scope topics
  • Audience level

Step 3: Research Complete Topic Landscape

Discover all subtopics:

  • Keyword research tools
  • Competitor analysis

  • Expert interviews
  • User questions (forums, Quora, Reddit)

Step 4: Create Ideal Topic Map

Structure comprehensive coverage:

Main Topic

│   ├── Detail 1.1
│   ├── Detail 1.2
│   └── Detail 1.3
├── Subtopic 2
│   ├── Detail 2.1
│   ├── Detail 2.2
│   └── Detail 2.3
└── Subtopic 3
    ├── Detail 3.1
    ├── Detail 3.2
