Internal Linking for SEO: A Beginner's Guide (With Real Examples)
Backlinks get all the attention, but internal links — the ones between your own pages — are the SEO lever most site owners control completely and use the least.
Why internal links matter
Internal links do three concrete things:
- They help search engines find your pages. A page that nothing else links to is much harder to discover and crawl regularly — even if it's in your sitemap.
- They pass authority around your site. When an established, well-ranking page links to a newer one, some of that page's authority flows to the page it links to. This is the same mechanism as backlinks, just internal.
- They keep visitors on your site longer. A reader who finishes one article and clicks into a related one is a reader who didn't bounce back to Google — which is itself a signal search engines pay attention to.
Unlike backlinks, you don't need to convince anyone else to give you an internal link. You control all of it.
The most common internal linking mistakes
- Only linking from the newest content. A new post links back to a few old ones, but the old, high-traffic pages never get updated to link forward to the new content — so the new page gets almost no internal link equity.
- Generic anchor text. "Click here" or "read more" tells search engines nothing about what the linked page is about. "See our internal linking guide" does.
- Linking to everything, relevant or not. A links section crammed with 15 barely-related posts dilutes the value of each link and reads as spam to both users and search engines.
- No hub pages. Sites with dozens of blog posts but no central page tying related ones together miss an easy structural win.
A simple framework: hub and spoke
The easiest mental model for internal linking is "hub and spoke":
- Hub pages are your broad, cornerstone content — a main service page, a comprehensive guide, a category page. These are the pages you most want to rank for competitive, high-value keywords.
- Spoke pages are narrower, more specific content — individual blog posts, FAQ answers, case studies — each covering one facet of the hub topic in depth.
Example: if you run a WordPress agency, your hub might be a "WordPress SEO Services" page. Spokes would be blog posts like "How Long Does WordPress SEO Take to Work," "Internal Linking for SEO," and "How to Write Image Alt Text" — each one links back up to the hub, and the hub links out to each spoke. That's exactly the structure this article and the SiteProPilot blog use.
What to link, concretely
- Every new post links to 2–3 relevant existing pages. Do this while writing, not as an afterthought — it's much easier to spot natural opportunities mid-draft.
- Update 1–2 old, high-traffic posts to link forward to each new piece of content you publish. This is the step almost everyone skips, and it's usually the highest-impact one.
- Link from spokes back to their hub, and from the hub out to its spokes, both directions.
- Use descriptive anchor text that reflects what the linked page is actually about — it doubles as a relevance signal.
- Don't link the same phrase to two different pages across your site — it confuses which page you actually want to rank for that phrase.
How many internal links is too many?
There's no hard limit, but a useful gut check: if you removed a link, would the sentence around it still make sense and still be useful? If a link exists purely to add a link, cut it. A 1,500-word article with 5–10 genuinely relevant internal links is normal and healthy; the same article with 40 links crammed into a "related posts" list at the bottom is not.
Auditing your existing internal links
If you've never done an internal linking pass, the highest-leverage place to start is your most-visited pages — check what they currently link to, and add links forward to newer or under-linked content that's genuinely relevant. Then check your newest content and make sure it links back to at least a couple of established pages.
