Internal Link Silo Planner - Free Online SEO Tool

The Internal Link Silo Planner is a free SEO tool that helps you design a logical website silo structure by mapping out a pillar page and its supporting cluster content before you start building or linking pages. Instead of guessing how your content should connect, this internal linking planner gives you a clear visual framework for organizing topics into silos, which strengthens topical authority and helps search engines understand the relationship between your pages.

How to Use the Tool

• Enter your Pillar Page (Main Topic) — for example, "Complete Guide to Content Marketing" — the central, comprehensive page that represents your core topic.
• List your Supporting Pages / Cluster Content, one per line, including all the related articles, guides, or subtopics that should link back to and support the pillar page.
• Generate your silo plan to visualize how the pillar and cluster pages should interlink, creating a clean topic cluster rather than a scattered site structure.

Best Practices for Silo Architecture

• Choose a pillar page topic broad enough to support multiple subtopics, but specific enough to stay focused.
• Make sure every supporting page has a clear, logical relevance to the pillar page — avoid mixing unrelated topics into the same silo.
• Use consistent, keyword-relevant anchor text when linking supporting pages back to the pillar page.
• Keep silos distinct from one another so link equity flows within a topic cluster instead of leaking across unrelated categories.

Why This Matters for SEO

A well-organized SEO silo architecture makes it easier for both users and search engine crawlers to navigate your site, discover related content, and understand your topical expertise. This topic cluster planner removes the guesswork from internal linking strategy, helping you build a scalable, search-friendly content structure that supports long-term organic growth.
