Internal Linking Strategy That Actually Moves Rankings

TL;DR: Internal links connect one page of your website to another. They distribute PageRank across your site, tell Google how your content is organised and related, and help visitors find what matters. Most websites have weak internal linking: too few links, random placement, or generic anchor text that tells Google nothing. Fixing it costs nothing but time. This guide covers the strategy, the anchor text rules, the structure to follow and the mistakes that cancel the benefit.

Why internal linking is the most overlooked SEO lever

Ask a website owner how they plan to improve rankings and you will hear about content, backlinks, site speed, maybe schema. Internal linking rarely makes the list.

That is a mistake, because internal linking is one of the few SEO levers that costs nothing, has no external dependencies and can show results within weeks. For a website that has never addressed it deliberately, it is often the highest-return fix available.

The neglect is understandable. Internal links are invisible to readers: a well-linked page looks identical to a poorly linked one. The work happens in the HTML and in Google’s crawlers, so it is easy to skip and easy to forget.

Google, however, is open about how it uses links. Its own documentation on crawlable links explains that Google finds pages by following them. Getting internal linking right is not glamorous. But it works.

What internal links actually do: three mechanisms

Mechanism 1: PageRank distribution

Google’s ranking systems grew out of PageRank, the idea that links work as votes of authority. A page that receives many links carries more authority than one that receives few. That applies to external backlinks and, importantly, to internal links too.

When a strong page on your site links to a weaker one, it passes part of its authority on. By linking deliberately from your strongest pages to the pages you most want to rank, you point accumulated authority exactly where it is needed. A clinic’s homepage is usually its most authoritative page, so a link from the homepage to the dental implants page passes that strength to a page that brings in enquiries.

Mechanism 2: topical relevance signals

Internal links signal how pages relate. When page A links to page B with anchor text that describes page B, Google registers a topical connection between the two. That strengthens the thematic coherence of a section of your site and feeds into topical authority across your niche.

An agency that links its guide to Google Business Profile optimisation to its guide to local citation building, using anchor text like “consistent citation data”, tells Google these topics belong together and that the site covers both.

Mechanism 3: crawl facilitation

Google discovers pages mainly through links. A page with no internal links pointing to it, an orphan page, is hard to find, index and rank. Making sure every page is linked from at least one other page guarantees that crawlers can reach all of your content.

The hierarchy: how to prioritise internal links

Effective internal linking follows a hierarchy that mirrors your content architecture.

The hub and spoke model

The most effective structure mirrors the topic cluster model, with two layers:

Hub pages (pillar pages): your highest-priority pages, with the most authority and the broadest coverage of a topic. Hubs link out to many related spoke pages and need many inbound links from cluster content.

Spoke pages (cluster pages): deeper pages on specific sub-topics. Each spoke links back to its hub and sideways to related spokes.

This two-way linking builds a network of topical relevance. The hub gains authority from the cluster, the cluster gains topical signal from the hub, and every page benefits from the others. If you are planning clusters, our guide to semantic SEO versus keyword SEO explains how to group topics before you link them.

Priority order

1. Revenue pages first. Service, product, booking and contact pages deserve the most internal links. Every relevant piece of content should link to at least one of them.
2. Pillar pages second. Comprehensive guides need links from across the cluster to keep their position as the anchor of the topic.
3. High-value informational pages third. Articles that capture top-of-funnel searches need enough internal links to get indexed and build ranking potential.
4. Supporting pages last. About and legal pages need only enough links to be discovered and indexed.

Anchor text: the rules that actually matter

Anchor text, the clickable words in a link, is one of the most influential parts of internal linking. It is also where most websites go wrong.

The three types

Exact match: the anchor is the target page’s primary keyword, for example “dental implants Sarajevo” linking to the dental implants page.

Partial match: the keyword appears alongside other words, such as “learn more about our dental implants”.

Descriptive: the anchor describes the content without the exact keyword, such as “our most advanced tooth replacement option”.

The rules

Rule 1: never use generic anchor text. “Click here”, “read more” and “learn more” tell Google nothing about the linked page. “Our dental implants service” or “how to build local citations” says exactly what the page covers.

Rule 2: vary the anchor text across links to the same page. Ten different descriptions of a page carry a richer signal than ten identical links.

Rule 3: keep it natural. The anchor must make sense in its sentence. Forced keyword insertion reads badly to people and looks low-quality.

Rule 4: link from related pages. A link to your implants page from an article about oral surgery carries more weight than one from a parking information page.

For internal links, exact and partial match anchors are normal. Over-optimised anchor text is a concern for external backlinks, but descriptive, keyword-relevant anchors between your own pages are standard practice. For the underlying mechanics, see Moz’s explanation of internal links and anchor text.

How many internal links per page

There is no fixed rule, but these ranges work in practice:

These are rules of thumb from practice, not limits set by Google. The principle is to link to every page a reader would find useful as a next step. Every link needs a reason to exist, and a page overloaded with links dilutes what each one passes on.

Finding internal linking opportunities

Most websites have far more opportunities than they have used.

Method 1: Google site search

Run this search in Google:

site:yourwebsite.com "keyword phrase"

It shows which pages already mention your target keyword. For each result, check whether the mention is a link. If not, you have found an instant, contextual opportunity.

Method 2: content audit spreadsheet

Export all URLs from your sitemap or Screaming Frog. For each URL record:

• The primary keyword it targets
• The number of inbound internal links
• The number of outbound internal links
• Whether it links to its relevant pillar page

Pages with very few inbound links are your highest-opportunity targets.

Method 3: Ahrefs or Semrush reports

Both tools include internal link auditing. Ahrefs shows each page’s internal link count (see their guide to internal links and PageRank flow), and Semrush’s Site Audit flags orphan pages, under-linked pages and broken internal links. For a free option, Screaming Frog’s SEO Spider crawls up to 500 URLs without a licence, which covers most local business websites.

Method 4: publish, then link backwards

Every time you publish a page, go back to the 3 to 5 most relevant existing pages and add a link to the new one from each. New content should never be an orphan from day one. This habit alone stops the problem from building up.

The orphan page problem

An orphan page receives no internal links from other pages on the same site. Google can only find it through the sitemap or an external link, it receives no PageRank flow, and it rarely ranks.

Orphan pages build up because:

• A page was created but never linked from existing content
• A page lost its links during a redesign
• New content was published in isolation, without connecting it to the site structure

Checking for orphans is basic maintenance. The fix is simple: find the 3 to 5 most relevant existing pages and add a link to the orphan from each.

Internal linking for local business websites

Local business websites are small, often 10 to 50 pages, which makes deliberate internal linking both more important and easier than on large sites.

The essential structure for a local business:

• Homepage links to every core service page, the About page and the Contact page
• Every service page links to related services, the Contact or Booking page and at least one relevant blog article
• Every blog article links to the most relevant service page, the pillar guide if one exists, and 1 to 2 related articles
• The Contact page links back to the homepage and the main service page

Here is an illustrative example (not a client result) for a dentist in Sarajevo. The “Dental implants” service page links to “Teeth whitening” and “Emergency dentist”, plus a blog post on what implants cost. That post links back to the implants page and to a pillar guide to dental care in the city, and the pillar guide links to every service page and every cluster article.

You can see the same pattern on this site. Our guides link to the matching service pages, such as local SEO and Google Business Profile management, and to each other. Even on a 15-page website, this builds a coherent topical network that Google can crawl, understand and trust. If you serve a specific sector, the same logic applies to pages such as our dental and medical SEO page.

Internal linking and AI search visibility

Internal linking also supports visibility in AI search, in two ways worth understanding separately.

First, retrieval systems can follow links within the pages they fetch. A well-linked page makes it more likely that related content from the same site is found too, which raises the chance that several of your pages contribute to one AI-generated answer.

Second, the topical coherence that internal linking creates helps show that a site genuinely understands a subject. A site where articles lead naturally to deeper treatment of related sub-topics reads as a comprehensive resource, while isolated posts read as a random collection. We cover the wider picture in what AI SEO is and how to rank in Google AI Overviews. The linking work that helps Google understand your site also helps AI systems retrieve and cite it.

Common internal linking mistakes

Broken links and slow pages often go together on neglected sites, so it is worth checking both. Our guide to Core Web Vitals covers the speed side.
