Internal links are the one SEO lever you fully control. You don't need backlinks from external sites. You don't need to wait for Google. You just need to connect your pages in a way that makes sense — and most sites don't.
Why internal linking matters
Internal links do three things: they help Google discover pages, they distribute link equity (ranking power) across your site, and they signal topical relationships. A page with zero inbound internal links is essentially invisible to Google — even if it's in your sitemap.
The hub-and-spoke model
The most effective internal linking architecture:
- Hub pages — your money pages (/features, /pricing, /templates). These target high-volume keywords.
- Spoke pages — blog posts, glossary entries, use-case pages. These target long-tail keywords.
- Links — every spoke links back to its hub. The hub links to all its spokes. Spokes link to each other where relevant.
The rules
- Every page needs ≥3 inbound internal links. Header nav counts as one. Footer counts as one. You need at least one more from a contextual in-content link.
- Homepage links to every money page. Your homepage has the most link equity. Distribute it to the pages that convert.
- Blog posts cross-link. Related posts link to each other. End-of-article CTAs link to product pages. In-content mentions link to glossary definitions or feature pages.
- No orphan pages. Every indexable page must be reachable by following internal links from the homepage. If Google can't get there by crawling, the sitemap alone isn't enough.
- Anchor text is descriptive. "Learn more" is wasted anchor text. "See our pricing plans" tells Google what the target page is about.
Where to place internal links
- Header navigation — all money pages
- Footer — all public pages + legal pages
- Blog post body — 3–5 contextual links to related content
- Sidebar / related content — 3–4 links to same-category posts
- End-of-article CTA — link to signup or a hub page
- Breadcrumbs — hierarchical links on every subpage
How to audit
Use Screaming Frog, Ahrefs Site Audit, or Semrush to crawl your site and identify: pages with fewer than 3 inbound links, orphan pages with zero inbound links, and pages with high link equity that could redistribute more. Fix the orphans first — they're invisible to Google.
