Internal Linking
The practice of linking one page on your website to another page on the same website. Distributes page authority, helps search engines understand site structure, and guides visitors to related content — one of the most underused SEO levers.
Internal Linking Is Free SEO Power Most Companies Ignore
Every time you publish a new blog post without linking to related content on your site, you are leaving ranking potential on the table. Internal links tell Google two things: what your content is about (through anchor text) and which pages are most important (through link volume and placement). A well-linked site ranks higher than a poorly linked site with the same content quality.
The other benefit is user experience. A visitor who reads about lead scoring should be one click away from your article about MQLs, your article about lead nurturing, and your product page. Internal links keep visitors on your site longer, reduce bounce rate, and guide them deeper into your funnel.
Internal Linking Best Practices
| Practice | Why It Matters |
|---|---|
| Use descriptive anchor text | ”learn about lead scoring” beats “click here” — anchor text tells Google what the target page is about |
| Link from high-authority pages | Pages with lots of backlinks pass authority through internal links |
| Link to deep pages | Your homepage has plenty of authority — your blog posts on page three need it more |
| Update old content with links to new content | New pages need internal link signals to rank faster |
| Create hub pages | Pillar pages that link to all cluster content concentrate topical authority |
The Internal Linking Audit
Crawl your site with a tool like Screaming Frog or Ahrefs Site Audit. Look for orphan pages (pages with zero internal links pointing to them), deep pages (pages that require 4+ clicks to reach from the homepage), and missed opportunities (related pages that should link to each other but do not). Fix these gaps and you will see ranking improvements within weeks — no new content required.
The Cluster Model for Internal Linking
The most effective internal linking strategy is the hub-and-spoke model. A pillar page (the hub) links to all related cluster articles (the spokes). Each cluster article links back to the pillar and to 2-3 other cluster articles. This creates a tightly interlinked web of content that signals topical authority to search engines and makes every page in the cluster stronger.
Frequently Asked Questions
How many internal links should a page have?
There is no strict limit, but 3-10 internal links per 1,000 words is a good range for blog content. More important than quantity is relevance — every internal link should send the reader to a genuinely related page that adds value. Pillar pages can have 20-30+ internal links because they serve as hubs. Do not force links where they do not fit naturally.
Which pages should you prioritize for internal links?
Link to your most important commercial pages — product pages, pricing, comparison pages, and high-converting landing pages. These pages often have fewer external backlinks, so internal links are their primary source of authority. Also prioritize new content that needs ranking signals and older content that is starting to decay.
