Ask most site owners about their SEO strategy and they’ll talk about keywords and backlinks. Almost nobody mentions the links inside their own site — which is strange, because internal linking is the one ranking factor you control completely, costs nothing, and most sites do terribly.
This guide covers how to build an internal linking strategy that actually moves rankings: hub pages, anchor text that helps (not hurts), finding orphan pages Google can’t reach, and the site structure that makes everything work. It’s the highest-ROI SEO work you’re probably ignoring.
What internal linking actually does for SEO
Every link from one of your pages to another passes a share of that page’s authority — sometimes called “link equity.” A page with many internal links pointing to it looks important to Google. A page with none looks unimportant, no matter how good its content is.
Internal links do three jobs. They help Google discover and crawl your pages — especially new ones. They distribute authority from your strongest pages (usually the homepage) to the pages you want ranking. And they guide visitors to related content, increasing time on site and pages per visit — both positive engagement signals.
Here’s what most people miss: Google’s crawlers follow links. If a page has zero internal links pointing to it — an “orphan page” — Google may never find it, or may find it through your sitemap but treat it as unimportant. Sitemaps help discovery; internal links confer importance.
Hub pages: the structure that scales
The most effective internal linking structure for content sites is the hub-and-spoke model. You create one comprehensive “hub” page per major topic, then link every related article (the “spokes”) to the hub — and the hub links back to each spoke.
For example, an SEO agency might have a hub page “SEO Services” linking to spokes on technical SEO, local SEO, ecommerce SEO, and link building. Each spoke links back to the hub and to sibling spokes where relevant. This tells Google: this site has deep, organized coverage of SEO.
Hub pages naturally attract the most internal links, which concentrates authority where it matters most — on the pages targeting your most valuable keywords. Our own SEO service page acts as a hub for our SEO content, and it shows in the rankings.
Anchor text: descriptive, varied, natural
Anchor text — the clickable words of a link — tells Google what the linked page is about. “Click here” tells Google nothing. “Our technical SEO audit process” tells Google exactly what to expect.
Use descriptive anchor text that includes relevant keywords, but vary it. If every internal link to your pricing page says “cheap web design prices,” that looks manipulative. Mix it up: “see our pricing,” “website costs,” “what we charge” — natural variation, the way a human would write.
The old fear of “over-optimizing” anchor text applies mainly to external backlinks. For internal links, Google is far more forgiving — but natural variation still reads better for humans, and humans are the ones clicking.
Find and fix your orphan pages
Orphan pages are more common than you’d think. Every blog post you published and never linked to again. Every landing page from an old campaign. Every page buried four clicks deep with no path from your main navigation.
Finding them is easy with the right tools. Screaming Frog (free for up to 500 URLs) crawls your site and flags pages with zero inbound internal links. Google Search Console’s Links report shows which pages get the fewest internal links. Ahrefs and Semrush site audits include orphan page detection.
Fixing them is straightforward: add contextual links from relevant existing pages. A two-year-old blog post about website speed should link to your new speed optimization guide — and the new guide should link back. Every page worth keeping deserves at least 2–3 inbound internal links.
Link from new posts to old (and old to new)
Here’s a habit that compounds: every time you publish a new post, link it to 3–5 relevant older posts. And just as important — go back and add links from 2–3 older posts to the new one.
Most people only do the first half. But older posts often have the most authority (they’ve had years to earn links and age). A link from a two-year-old post to your brand-new guide passes real authority immediately — it’s the fastest way to get a new page noticed by Google.
Make this part of your publishing checklist. It takes five minutes per post and the cumulative effect over dozens of posts is enormous. Sites that do this consistently see new posts indexed and ranking weeks faster.
How many internal links per page?
There’s no magic number, but practical guidelines help. A 1,500-word blog post should contain roughly 5–10 internal links — enough to be useful, not so many that every other sentence is blue. Your homepage and main service pages can carry more, since they’re navigation hubs.
What matters more than count is placement and relevance. A contextual link inside a paragraph (“we cover this in our website speed guide“) carries more weight than a link buried in a footer widget. Google understands that in-content links are editorial endorsements; footer links are navigation.
Also: every important page should be reachable within 3 clicks from the homepage. Deeper than that, and both Google and visitors start giving up. If your pricing page is four clicks deep, your site structure needs work regardless of linking.
Internal linking mistakes that waste the effort
The most common mistake is linking everything to the homepage and contact page. Your homepage already has the most authority on your site — it doesn’t need more. Point links at the pages you’re trying to rank: service pages, key blog posts, landing pages.
Other classics: nofollow-ing your own internal links (never do this — it blocks authority flow for no benefit), linking to redirected or 404 pages (audit quarterly), and using the same anchor text for different destination pages (confuses Google about which page is about what).
And the subtlest mistake: linking to a page once and forgetting it. Internal linking is maintenance, not a one-time project. Schedule a quarterly review — it takes an hour with the right tools and keeps your site’s authority flowing where it matters.
The 1-hour internal linking audit (do this today)
Want the quick win? Here’s a one-hour audit anyone can do. First, pull your Google Search Console Links report and list your 10 pages with the fewest internal links — those are your orphans. Second, list the 5 pages you most want ranking (services, key posts). Third, find 3–5 natural linking opportunities from existing content to each priority page, and add them.
That’s it. One hour, and you’ve redirected your site’s existing authority toward the pages that earn you money. No new content, no backlinks, no budget — just better plumbing. Then make it a habit: every new post links to old ones, and old ones link to new ones.

Frequently asked questions
What is an internal linking strategy?
An internal linking strategy is a deliberate plan for how pages on your website link to each other — using hub pages, descriptive anchor text, and regular audits to distribute authority to your most important pages. Good internal linking helps Google discover, crawl, and rank your content while guiding visitors to related pages.
How many internal links should a page have?
A 1,500-word blog post should have roughly 5–10 internal links; homepages and service pages can carry more. Relevance and placement matter more than count — contextual links inside paragraphs carry more weight than footer or sidebar links. Every important page should be reachable within 3 clicks of the homepage.
What are orphan pages in SEO?
Orphan pages are pages with no internal links pointing to them. Google may never crawl them, or may treat them as unimportant even if the content is good. Find them with Screaming Frog or Search Console’s Links report, then add contextual links from relevant existing pages — every page worth keeping deserves 2–3 inbound internal links.
Does internal linking help rankings?
Yes. Internal links distribute authority from strong pages to the pages you want ranking, help Google discover and crawl content, and improve engagement metrics like time on site. It’s one of the few ranking factors you control completely — and most sites underuse it badly.
Should I nofollow internal links?
No — never nofollow your own internal links. Nofollow tells Google not to pass authority through the link, which defeats the entire purpose of internal linking. Save nofollow for untrusted external links like user-generated content or paid placements.
What is good anchor text for internal links?
Good anchor text describes the linked page with relevant keywords — “our technical SEO audit process” instead of “click here.” Vary your anchor text naturally across links to the same page. Google is forgiving of keyword-rich internal anchor text, but natural variation reads better for humans.
