Internal links

By Paul Brock·Updated on 22-04-2026
TL;DR

Internal links are links between pages on the same domain, a lever for crawlability, authority distribution and thematic context.

Internal links are the only ranking factor you control 100%. Well structured, they let link equity flow to your most important pages, support topical authority via clusters, and ensure crawlers reach all content. Rule of thumb: every indexable page gets at least one internal link.

Example

An SEO agency connects pillar page 'SEO services' to ten supporting articles ('What is canonical tag', 'What is indexing', etc.) with descriptive anchors. Each article links back to the pillar.

Frequently asked questions

How many internal links per page is optimal?

3-8 contextual links in body text is natural. Menu and footer links weigh less than editorial links in body content.
