External backlinks get most of the SEO attention, but internal links are the knobs you control completely. They tell crawlers which pages exist, how important each one is relative to the others, and what a page is about through anchor text.

A page with zero internal links pointing at it is effectively invisible — crawlers may never find it, and even if they do, no authority flows to it from the rest of the site.

What Good Internal Linking Looks Like

Every article should link to at least two related articles. Category pages should link to their best articles, and the homepage should surface the most important categories. Think of it as a pyramid: authority flows down from the homepage through categories to individual articles.

Anchor text matters. “Click here” is wasted. “How to fix a slow LCP score” tells the crawler and the reader exactly what they’re about to get.

A Simple Audit Process

  1. Export all your published URLs (your sitemap works for this).
  2. For each URL, count inbound internal links using a crawler like Screaming Frog or the free version of Ahrefs Site Audit.
  3. Any page with fewer than two internal links pointing to it is an orphan. Add links from topically related articles or from the relevant category page.

Run this audit every time you publish a batch of new content, not just once at launch. New articles have zero inbound links by definition — fix that in the same publishing session.

Common Mistakes

Over-linking the homepage. Your homepage already has maximum authority. Adding twenty links from it to different articles dilutes each one. Reserve homepage links for your absolute best or newest content.

Ignoring anchor text variety. If every link to a page uses the same three words, it can look manipulative. Vary phrasing naturally — different sentences will produce different anchors.

Broken internal links. A 404 wastes the crawl budget and kills any authority that link would pass. Audit for them quarterly.
