Topical Map

What Is a Topical Map?

Without a topical map, your content creation runs on gut feeling rather than strategy. The map reveals where thematic gaps exist, which content pieces can strengthen each other, and where you can outrank competitors with targeted articles. It is the strategic foundation for building topical authority and prevents you from investing resources in redundant or irrelevant content.

A topical map is a strategic overview of all topics, subtopics, and their relationships that a website should cover. It serves as a blueprint for content strategy and ensures that a domain covers a subject area completely and coherently. Unlike a simple keyword list, a topical map shows the hierarchical and semantic connections between content pieces.

Building a topical map starts with the core topic of the website. From there, main categories, subcategories, and individual topics branch out. For an SEO website, the map might look like this: core topic “SEO” → main categories “Technical SEO,” “Content SEO,” “Off-Page SEO” → subtopics like “Crawling,” “Core Web Vitals,” “Keyword Research” and so on. Each node corresponds to at least one piece of content on the website, connected through internal links.

For Google, a complete topical map signals thematic authority — measurable through the siteFocusScore and the site2vec embedding. Websites that cover a topic comprehensively rank better than those with scattered articles. Use an Entity Gap Analysis to find gaps in your map, and build your content systematically as Content Hubs.
