The Anatomy of a Topic Cluster

In 2026, Google ranks websites based on Topical Authority, not just single-keyword optimization. To rank for competitive terms, you need a structured network of content.

Pillar Page
(High Volume, Broad Topic)
e.g., "Ultimate Guide to Running Shoes"
Cluster Article 1
(Long-tail)
"Best Shoes for Flat Feet"
Cluster Article 2
(Long-tail)
"How to Clean Running Shoes"
Cluster Article 3
(Long-tail)
"When to Replace Your Shoes"

Jaccard Similarity Algorithm

Unlike basic tools that just look for an exact matching word, our tool uses Jaccard Similarity. It tokenizes phrases, removes stop words (like "how", "to", "the"), and calculates the mathematical overlap between search intents. This groups "baking a cake" and "how to bake cakes" together perfectly.

100% Free & Private

Enterprise SEO tools charge $100+/month for keyword clustering. We run the intensive string-matching algorithms directly in your browser's RAM via Web Workers. No data is sent to a server, and there are no export limits.

Ready-to-Write Outlines

Exporting to CSV is great for spreadsheets, but our "Copy Markdown" feature turns your clustered groups into formatted `H1`, `H2`, and `H3` outlines that you can paste directly into WordPress, Ghost, or Notion.
