What is Internal Linking?

Definition

Internal linking refers to hyperlinks that connect one page of your website to another page on the same domain. Unlike external links (which point to other websites), internal links help users navigate your site and help search engines discover, crawl, and understand the structure and hierarchy of your content. A well-planned internal linking strategy distributes page authority (link equity) throughout your site and establishes topical relationships between related pages.

There are two main types of internal links: navigational links (in menus, sidebars, footers, and breadcrumbs that appear on every page) and contextual links (within the body content of a page, linking to related pages where the context is relevant). Contextual links carry more SEO weight because they're placed within meaningful content and use descriptive anchor text. Both types work together to create a cohesive site architecture that serves users and search engines.

Why It Matters

Internal linking is one of the most underused yet powerful SEO techniques. It helps search engines discover new pages (a page with no internal links pointing to it, an "orphan page", may never be crawled or indexed), understand which pages are most important (pages with more internal links are seen as higher priority), and establish topical relationships between content. You have complete control over your internal links, making this one of the few SEO levers that requires no external cooperation.

For users, internal links improve navigation, reduce bounce rates, and increase time on site by guiding visitors to relevant related content. Well-placed contextual links within blog posts or product descriptions create natural reading paths that keep visitors engaged longer. Internal linking also distributes ranking authority from your strongest pages (those with the most backlinks) to deeper pages that need a boost, effectively leveraging your existing authority across your entire site.

How to Measure

Audit your internal link structure by crawling your site to map all link connections. Key metrics include: number of internal links per page, orphan pages (pages with no internal links pointing to them), link depth (how many clicks from the homepage to reach a page), and anchor text relevance. Important pages, those you most want to rank, should be reachable within 3 clicks from the homepage and should have a higher number of internal links pointing to them.

Look for common issues: pages with very few internal links (underlinked), pages with an excessive number of links (diluting link equity), broken internal links (returning 404 errors), and redirect chains within internal links (link → redirect → redirect → page). Also check that your anchor text is descriptive and varied, using the same generic anchor text ("click here", "read more") misses an opportunity to signal relevance to search engines.

Best Practices

Link from high-authority pages to pages you want to boost. Your homepage and most-linked-to pages carry the most authority, adding internal links from these pages passes that authority downstream. Use descriptive, keyword-relevant anchor text for contextual links ("learn about conversion rate optimization" is far better than "click here"). Vary your anchor text naturally rather than using the exact same phrase every time.

Audit for orphan pages monthly, any page not linked from at least one other page is essentially invisible to search engines. Add contextual links within your content where they genuinely help the reader, not just for SEO. Create topic clusters where a pillar page links to related subtopic pages and vice versa, forming a hub-and-spoke structure that signals topical authority. Fix broken internal links immediately, as they waste crawl budget and create dead ends for both users and search engines.
