Topical coverage is the breadth and depth of content a source provides on a given topic. Topical coverage measures how completely a knowledge domain is addressed through content pieces that cover sub-topics, entities, attributes, and queries within the domain.
How is Topical Coverage Measured?
Topical coverage is measured across 3 dimensions:
- Breadth: the number of distinct sub-topics and entities covered within the knowledge domain.
- Depth: the level of detail and expertise demonstrated for each sub-topic.
- Completeness: the percentage of known queries and intents within the topic that are addressed.
A topical map defines the required coverage by organizing content into a core section and an outer section.
What is the Relationship Between Topical Coverage and Topical Authority?
Topical authority requires comprehensive topical coverage. A source cannot establish authority on a topic without covering the essential sub-topics, entities, and queries that define the knowledge domain. Incomplete coverage signals to search engines that the source lacks the expertise needed to be the primary authority.
How Does a Semantic Content Network Enable Topical Coverage?
A semantic content network is the structural implementation of topical coverage. Each node in the network represents a content piece that covers a specific sub-topic. The connections between nodes ensure that the coverage is coherent, non-overlapping, and collectively comprehensive.
Key Takeaway
Topical coverage quantifies how completely a source addresses a knowledge domain. It is measured by breadth, depth, and completeness of sub-topic coverage. Comprehensive topical coverage, organized through a semantic content network and topical map, is the foundation for establishing topical authority.
