Internal Linking Best Practices: Build a Topic Graph That Ranks

A practical internal linking framework for SEO and GEO: pillar links, sibling links, anchor rules, audits, and how to scale linking safely.

Rankwise Team·Updated Jan 6, 2026·3 min read

Internal links are how you turn isolated pages into a connected system that search engines (and humans) can understand.

If you implement just the rules in this guide, your content becomes easier to crawl, easier to navigate, and stronger as a cluster.

The 3 internal link types you actually need

1) Pillar links (up the tree)

Every cluster page links to its parent pillar/topic hub.

2) Sibling links (across the tree)

Every page links to 2–4 related pages at the same level.

3) Action links (toward value)

Only when relevant, link to a product or next step.

The minimal internal linking checklist

Every resource page should have:

  • 1 link to its topic hub (pillar)
  • 2–4 sibling links to related resources
  • 1 "next step" link (only if it matches intent)
  • No orphan pages

Anchor text rules (simple + effective)

  • Prefer descriptive anchors (not "click here")
  • Avoid exact-match spam ("best geo seo ai search")
  • Use natural language that matches the destination's promise

Good: "topic cluster strategy" Bad: "AI search keyword SEO geo optimization tips"

Where to put internal links

You want links in:

  • the body (contextual)
  • a "Related resources" module (consistent)
  • optionally a sidebar/TOC area (desktop)

Avoid:

  • link dumping (a huge list with no reason)
  • footer-only linking (low value)

Linking patterns for a GEO cluster (example)

If you have:

  • What is GEO?
  • AI citations
  • Optimizing for ChatGPT
  • Keyword research

Then "What is GEO?" should link to:

Auditing your internal links

Do a monthly audit on your top pages:

Quick audit questions

  • Are there orphan pages?
  • Are top pages linking to the best next actions?
  • Do you have broken internal links?
  • Are your topic hubs getting consistent links?

Audit table template

Common mistakes

  • Only linking "up," never sideways
  • Writing great pages but leaving them orphaned
  • Using keyword-stuffed anchors
  • Creating too many hubs (fragmented authority)
