Map topical authority across your entire site
Use the vector index to see how your content clusters by topic, how deep each cluster goes, and where your topical coverage has gaps - so your team can plan strategically.
Illustrative preview - actual platform experience may differ.
How it works
From indexed content to topical authority map in three steps.
Index everything
Morrison crawls and embeds your entire site. The vector database naturally clusters pages by semantic similarity.
Map clusters
Ask the AI to identify your topic clusters, count coverage depth, and check for subtopic completeness within each area.
Find the gaps
Get reports showing where you have deep authority, where coverage is thin, and where entire subtopics are missing.
What you can do
Semantic cluster detection
The vector index groups your pages by semantic similarity - revealing natural topic clusters based on actual content, not just URL structure.
Coverage depth analysis
For each topic cluster, ask the AI to assess how many pages you have, how thoroughly they cover the topic, and whether key subtopics are missing.
SERP authority benchmarking
Use the SerpAPI workflow step to pull search results for cluster-level queries. Ask the AI to compare your coverage against what's ranking and where competitors go deeper.
Subtopic gap detection
Ask the AI to break a broad topic into expected subtopics, then check which ones your site covers and which are missing entirely.
Authority vs. performance
Use workflows to cross-reference topic clusters with Search Console data. Ask the AI whether clusters with deeper coverage perform better - and where the correlation breaks.
Visual cluster reports
Get structured reports showing your topic landscape: strong areas, thin areas, and blind spots - ready for strategic planning sessions.
Frequently asked questions
What is topical authority in SEO?
Topical authority measures how comprehensively your website covers a subject area. Sites with deep, well-interlinked content clusters on a topic tend to rank higher for related queries. Mapping your authority helps you find coverage gaps.
How does Morrison map topical authority?
Morrison uses your indexed content and its vector embeddings to cluster pages by topic similarity. You can chat with the AI to explore cluster depth, discover thin areas, and identify where adding content would strengthen your authority.
How is this different from a content gap analysis?
Topical authority mapping looks inward at your own coverage depth and cluster structure. Content gap analysis compares your content against competitor SERP data to find topics you haven't covered at all. They're complementary – use both for a complete picture.
