Internal Linking: The Free SEO Almost Every Site Skips

Dollar figures in this article are US dollars. Our Australian prices are on the pricing page.

Everyone worries about getting links from other websites, which is slow, difficult and largely outside your control. Almost nobody thinks about the links on their own site, which are instant, free and entirely within it.

Internal linking is the most neglected lever in small business SEO, and it is the one you can pull this afternoon.

What Internal Links Actually Do

• They tell search engines what exists. Crawlers follow links. A page reachable only from the sitemap is a page you have told nobody about.
• They distribute authority. Whatever credibility your site has flows along its internal links. Where you point them decides which pages benefit.
• They describe the destination. The words in the link tell Google what the target page is about — which is why "click here" is a wasted link.
• They keep people reading. The commercial benefit, and the one that shows up in inquiries rather than rankings.

Find Your Orphan Pages First

An orphan page has no internal links pointing at it. They accumulate quietly: a page removed from the menu during a redesign, a service added and never linked, an old landing page.

To find them without paid tools: list every page from your sitemap, then use your site's own search or a site: search to check which appear in your navigation and body content. Anything on the sitemap that nothing links to is an orphan.

Then either link to it properly or remove it. A page worth keeping is worth linking to; one not worth linking to is usually thin content that is mildly harming you.

Write the Link Text Properly

The clickable words are the single biggest signal about the destination.

• Bad: "For more information, click here."
• Better: "Read more about our bathroom renovations."
• Best: "We also do commercial bathroom renovations in Perth."

Vary the wording naturally rather than repeating one exact phrase everywhere, which reads as manipulation to both people and search engines. And "click here" is also an accessibility problem: screen reader users often navigate by pulling up a list of links, and a list of eleven identical "click here" entries is useless — see accessibility for small businesses.

Where the Links Should Point

The structural principle: informational content should link to commercial pages, because the informational content is what attracts the search traffic and the commercial page is what earns the money.

In practice:

• Every blog post links to at least one service page, in context, where it genuinely helps the reader.
• Related posts link to each other. Somebody reading about choosing a host will want the article about backups.
• Service pages link to relevant proof — case studies, the gallery, pricing.
• Your most important page should be linked from the most places. If a service is 60% of revenue, it should not be linked from three pages while a minor one is linked from twelve.

Group Content into Clusters

The structure that works: one comprehensive "pillar" page for a broad subject, with detailed articles underneath it. Every article links up to the pillar, the pillar links down to every article, and articles link sideways to each other where relevant.

This does two things. It concentrates authority on the pillar, which is the page that can realistically rank for the broad, valuable query. And it makes the site's structure legible — a crawler can see that these fourteen pages are one subject rather than fourteen unrelated ones.

It is exactly how this blog is arranged: each article belongs to a guide, links up to it from the breadcrumb and the footer, and the guide lists everything beneath it.

Four Mistakes

• Only linking from the navigation. Menu links are fine and every page has them, so they do little to distinguish importance. In-content links carry more weight because they are contextual and deliberate.
• Too many links on one page. Fifty links on a 600-word page dilutes every one of them and reads as spam. A handful of genuinely relevant links beats a wall.
• Linking with the same exact phrase every time. Vary it.
• Leaving broken internal links. They waste crawl budget and irritate readers. Check them after any restructure, and see migrating without losing rankings for the redirect discipline.

A One-Hour Exercise

1. List your pages, and mark the three that make you the most money.
2. Open every other page and ask: is there a natural place to link to one of those three? Add it, in real sentences, where it genuinely helps.
3. Find the orphans and either link them or remove them.
4. Fix every "click here".
5. Check for broken internal links.

That is an hour, it costs nothing, and it is more valuable than most of what gets sold as an SEO retainer's first month. Our free website check flags orphan pages and broken internal links automatically if you would rather not do the crawling by hand.

Common Questions

What Is Internal Linking and Why Does It Matter for SEO?

Links from one page of your site to another. They tell search engines which pages exist, distribute authority around your site, describe what the destination page is about through the link text, and keep readers moving toward your commercial pages. They are free and entirely under your control, unlike links from other sites.

What Is an Orphan Page?

A page with no internal links pointing at it. They accumulate quietly — a page dropped from the menu during a redesign, a service added and never linked. Either link to it properly or remove it: a page worth keeping is worth linking to, and one that is not is usually thin content mildly harming you.

What Should Link Text Say?

Describe the destination. "Our bathroom renovations" is far better than "click here", because the words are the strongest signal about what the target page covers. Vary the phrasing naturally rather than repeating one exact phrase, and note that "click here" is also an accessibility problem for screen reader users navigating by link list.

How Many Internal Links Should a Page Have?

A handful of genuinely relevant ones. Fifty links on a short page dilutes each of them and reads as spam. Prioritize in-content links over navigation links — menu links appear on every page so they do little to signal importance, while a contextual link inside an article is deliberate.

What Is a Content Cluster in SEO?

One comprehensive pillar page on a broad subject, with detailed articles beneath it. Every article links up to the pillar, the pillar links down to all of them, and articles link sideways where relevant. It concentrates authority on the page that can rank for the broad valuable query, and makes the site structure legible to a crawler.
