Build Topic Clusters Around Pillar Pages

Also known as: Content Clusters, Pillar-and-Spoke Model, Topical Hubs, Semantic Silos

Group related content around a central pillar page and interlink it clearly, so readers and search engines see how deeply you cover a subject; a common SEO practice.

How does it work?

  1. 1. Choose a topic you truly know

    Pick one topic you have real expertise in, then list the questions people ask about it from Search Console, support tickets and Bing grounding queries.

  2. 2. Plan one pillar and distinct subpages

    Write a pillar page covering the topic broadly; create a subpage only where a sub-question needs its own depth, never one per wording variant.

  3. 3. Add original expertise to every page

    Each page needs first-hand experience, own data or analysis; mainly summarising what others say without adding value is a warning sign.

  4. 4. Link pillar and subpages both ways

    Use <a href> links with descriptive anchor text from the pillar to each subpage, back to the pillar, and between closely related subpages.

  5. 5. Merge overlapping or thin pages

    Where two pages answer the same question, combine them into one stronger page and redirect the old URL to it.

  6. 6. Check links and AI visibility

    Crawl the site to confirm every cluster page has internal links, then track those pages in Search Console's Generative AI report and Bing AI Performance.
