What it means
Internal links are hyperlinks on a webpage that point to other pages on the same domain. Every site has them - main navigation, footer links, contextual links inside content, related-content modules, breadcrumbs.
Internal linking strategy is the deliberate planning of which pages link to which others, with what anchor text, and how often.
Why it matters
Internal links do three jobs:
- Distribute authority - pages with strong external backlinks pass some of that authority to the pages they link to internally
- Define topical relationships - when your pillar page links to ten supporting articles, you signal that those pages cluster together
- Improve crawl coverage - search engines and AI crawlers find new pages by following links, so well-linked pages are discovered faster
For AEO specifically, well-linked content clusters help AI engines understand what your site is an authority on, which improves citation odds for category queries.
How it's used
A simple internal linking strategy:
- Build pillar pages on your three to five core topics
- Link every supporting page back to the relevant pillar
- Link supporting pages to each other when contextually relevant
- Use descriptive anchor text - "AEO services" not "click here"
- Add internal links inside the body of content, not just in sidebars and footers
- Audit periodically for broken links and orphan pages
A well-linked site of 50 pages outperforms a poorly-linked site of 500.
