Internal linking for small websites: an easy 3 tier structure
Small websites usually lose not because they lack content, but because their pages stand in isolation: good articles never point at the service pages, service pages never lead down to supporting posts, and Google cannot tell which pages matter. This article lays out a 3 tier internal linking model simple enough to build in an afternoon, designed for websites under 100 pages.
Quick summary: Internal linking is the cheapest way to tell Google which pages matter. For a website under 100 pages, a 3 tier model is enough: the homepage points down to 3-6 pillar pages, each pillar points down to the supporting posts in its topic, and supporting posts point back up to their pillar and across to each other. Anchor text must describe the destination page instead of "read more" or "click here". The three most common mistakes: orphan pages with no links pointing at them, generic anchors, and pages connected only through the menu. All of it can be checked for free with Google Search Console and the site: search operator.
Why does internal linking matter so much for small websites?
Internal links do three jobs at once: they help Google discover new pages by following paths, help Google understand what each page is about through anchor text and surrounding context, and distribute importance between the pages of a site. A Google representative put it plainly in the Search Central question and answer series: internal linking is one of the biggest things a site owner can do to show Google and visitors which pages they consider important.
The numbers back that up. A study published by Zyppy in 2022 analysed 23 million internal links across 1,800 websites, roughly 520,000 URLs matched against Google Search Console data. URLs with only 0-4 internal links pointing at them averaged a mere 2 clicks from Google search, while the group with 40-44 links received 4 times as many. Beyond roughly 44 links the returns flattened out, which means the goal is not to cram in as many links as possible, but to make sure important pages are never starved of them.
The good news for a small business: unlike backlinks, which you have to earn from other websites, internal links are entirely under your control, cost nothing, and can be fixed today. On a site under 100 pages, the whole review and rewiring job usually fits inside 2-4 hours of work.
The 3 tier structure: homepage, pillar pages, supporting posts
An SME website does not need a complicated architecture diagram. Three tiers are enough:
- Tier 1 - The homepage. The heaviest page on the site, because it collects the most backlinks. The homepage points directly down to the pillar pages, not scattergun to individual posts.
- Tier 2 - Pillar pages. Each pillar represents one main topic or service group, for example the web design service page, the AI agent overview page, or a topic category page on the blog. For a site under 100 pages, 3-6 pillars is a sensible number. Each pillar points down to every supporting post in its topic.
- Tier 3 - Supporting posts. Detailed articles that each answer one specific question. Every supporting post points back up to its pillar page and across to 2-3 other posts in the same topic cluster.
This model is also known as the topic cluster structure. The 3 click rule follows common crawl depth guidance: the further a page sits from the homepage, the less often it gets crawled and the fewer link signals it receives.
The strength of this model is that it works in both directions. A pillar page collects weight from all the supporting posts pointing up at it, so it can compete for harder keywords; every supporting post receives a link down from its pillar, so nothing is ever orphaned. A clear structure also helps machines understand how pages relate to each other, working in the same direction as structured data markup, which we covered in schema markup for AI and search engines: one describes relationships through links, the other through labelled data.
Descriptive anchor text: how should it be written?
Anchor text is the clickable part of a link, and to Google it works like the label on a shipping box: read the label and you know what is inside. Google's own documentation on links recommends anchors that are concise but accurately describe the destination page. "Web design pricing for small businesses" is a good anchor; "click here" says nothing at all.
The same 23 million link study found two details worth acting on: destination pages with a wider variety of anchor text pointing at them correlated strongly with higher search traffic, and pages that received at least one anchor exactly matching their target phrase drew roughly 5 times as many clicks as pages without one. The safe way to apply this on a small site: every time you point at the same page, phrase the anchor slightly differently instead of repeating it word for word, and make sure the sentence around the link talks about the same subject as the destination.
| Situation | Weak anchor | Strong anchor |
|---|---|---|
| Linking to a service page | read more | web design services for SMEs |
| Linking to a how to guide | here | how to test your website speed yourself |
| Linking to a pricing page | this link | monthly chatbot pricing |
| Cross linking in a cluster | previous article | GEO versus SEO compared for businesses |
Descriptive anchors also help readers decide whether to click, so click through on the links themselves tends to rise.
The three most common internal linking mistakes on SME websites
- Orphan pages. The page exists, sometimes even sits in the sitemap, but not a single other page links to it. Google discovers content mainly by following links, so orphan pages get indexed late or get treated as unimportant even when the content is good. Typical victims: landing pages built for ad campaigns, and older articles that fell off the category page.
- "Read more", "here", "click here" anchors. The link exists but carries no information. Dozens of links all labelled "read more", each pointing somewhere different, leave both machines and humans unable to tell the destinations apart.
- Pages connected only through the menu or footer. Menu links repeat identically on every page, so they carry almost no context. Important pages need to be mentioned inside the body of related pages, where the surrounding sentences explain why they are worth reading.
A fourth bad habit deserves a mention: scattering cross links between unrelated articles just to "have links". A link between two pages on different topics teaches Google nothing and dilutes the cluster structure. The short rule: only link when the person reading that exact sentence has a genuine reason to click through.
How to check it all without paid tools
On a website under 100 pages, you do not need paid software to audit internal links. These four methods are all free:
- Google Search Console, Links section. The "Internal links" report lists how many links point at each page. If a core sales page sits near the bottom of that list, that is a signal to fix; a page missing from the list entirely is very likely an orphan.
- Compare the sitemap against that report. Open sitemap.xml and check each URL against the internal links report. A URL present in the sitemap but absent from the report is the clearest orphan page candidate.
- The site: search operator. Type site:yourdomain.com plus a page's keyword to see whether the page is indexed, and which page Google currently prefers for that topic.
- A free crawler. The free tier of Screaming Frog crawls up to 500 URLs, more than enough for a site under 100 pages: the inlink count column and the click depth column instantly show which pages are being left behind.
- List the 3-6 pages that matter most to revenue as your pillars.
- Sort every existing article into the topic cluster of one pillar.
- From each pillar, link down to every post in its cluster with descriptive anchors.
- In each post, link back up to the pillar and across to 2-3 posts in the same cluster.
- Compare the sitemap with the internal links report to catch orphan pages.
- Check that no page sits more than 3 clicks from the homepage, then measure again after 4-6 weeks.
Keep the scope clear: internal linking solves the problems of importance distribution and crawlability, and does not replace the other technical work. Before rewiring links, make sure your pages are not blocked from indexing and are not painfully slow; the priority order for that group of tasks is covered in website speed and Core Web Vitals: what to fix first. And if your goal is to be cited by AI tools, a clear topic cluster structure is a good foundation, but the success metrics are different, as compared in GEO versus SEO: which to invest in first.

FAQ - Frequently asked questions
How many internal links should one article have?
There is no mandatory number. Zyppy's 2022 study of 23 million internal links found that URLs with 0-4 internal links pointing at them averaged only 2 clicks from Google, the 40-44 link group received 4 times as many, and beyond roughly 44 links the returns flattened out. For a website under 100 pages, 3-8 contextual links per article is a sensible range, as long as every link is genuinely relevant.
What is an orphan page and why does it need fixing?
An orphan page is a page with no internal links pointing to it at all. Google discovers new pages mainly by following links, so an orphan page may not get indexed, or may be treated as unimportant even when the content is good. The fix: add links from the relevant pillar page or from related articles pointing to that page.
Do menu and footer links count as internal links?
Yes, but their descriptive value is low because they repeat identically on every page and the anchor text is usually very short. Links placed inside the body of an article, surrounded by context, help Google understand the relationship between two pages far better. A page that is only reachable from the menu is still likely to be treated as weaker than a page mentioned inside content.
