Internal Linking: The Simplest System That Works

Ask a small business owner about SEO and they will talk about keywords and backlinks. Almost none will mention the links between their own pages — yet those links decide how authority flows through the site, how quickly Google discovers new pages, and what Google believes each page is about. It is the only major ranking input where you control both ends of every link.

Why internal links matter more than you think

Internal links do three distinct jobs, and each one is worth understanding before you place a single link.

• Authority flow. PageRank — yes, Google still uses a version of it — passes through links, internal ones included. When a strong page links to a weak one, some of that strength transfers. Your homepage is usually your most-linked page; where it links matters enormously.
• Crawl discovery. Googlebot finds pages by following links. A page with no internal links pointing at it may sit unindexed for weeks, or forever. If you have ever wondered why your website isn’t showing on Google, missing internal links is one of the usual suspects.
• Relevance signals. The clickable text of a link — the anchor — tells Google what the destination page is about. Fifty internal links saying “boiler installation Sheffield” are a clearer signal than anything you write on the page itself.

The hub-and-spoke model for small sites

Enterprise sites need elaborate architectures. A site with 15–60 pages needs exactly one pattern: hubs and spokes. A hub is a page targeting your big commercial phrase. Spokes are narrower pages that each answer one related question, link up to the hub, and link sideways to one or two sibling spokes. The hub links down to every spoke.

A worked example: a Sheffield builder

Say the money page is “Loft Conversions Sheffield” — that is the hub. The spokes are the questions every customer asks before they buy:

• “How much does a loft conversion cost in 2026?” → links to the hub with the anchor “loft conversions in Sheffield”
• “Do I need planning permission for a loft conversion?” → links to the hub, and sideways to the cost guide
• “Dormer vs Velux: which loft conversion adds more value?” → links to the hub, and sideways to the planning guide
• The hub links out to all three, each with a descriptive anchor.

Each spoke is easy to rank for on its own (low competition, specific question), and every one of them pushes authority and relevance at the page that wins the £40,000 job. One hub per core service, three to six spokes each, built over months, not weekends. Whatever your trade, the structure is the same — our industry SEO guides map out hub-and-spoke examples sector by sector.

Anchor text: descriptive beats “click here” every time

The anchor is the part most sites waste. “Click here”, “read more”, “this page” — these tell Google nothing about the destination. Google’s own link best practices say it directly: use concise, descriptive anchor text that tells people and search engines what the linked page is about.

• Bad: “To learn about our boiler services, click here.”
• Good: “We also handle boiler servicing and repairs across south Manchester” — with “boiler servicing and repairs” as the linked anchor.
• Vary the wording naturally. If every link to a page uses the identical phrase, it reads like manipulation; if no link uses the key phrase, you have wasted the signal. Aim for the keyword or a close variant in most anchors, plain English in the rest.

The 30-minute monthly routine

Internal linking fails as a one-off project and works as a habit. Here is the entire routine — set a calendar reminder and do it with your coffee on the first Monday of the month.

1. List what you published last month (usually one to three pages). For each new page, add two or three links TO it from your strongest relevant pages, with descriptive anchors.
2. From each new page, add links OUT to its hub and one sibling page. New pages should never be dead ends.
3. Open Search Console, find one page whose ranking you most want to improve, and search Google for site:yourdomain.co.uk plus its topic phrase. Every page in those results that does not already link to your target page is a linking opportunity — add the best two or three.
4. Spot-check three old blog posts for “click here” anchors and rewrite them.
5. Done. Log it and stop — consistency beats volume here.

Step 3 is the quiet powerhouse: the site: search surfaces every page Google already associates with your topic, which is exactly the set of pages whose links count most. It pairs perfectly with the CTR work in our Search Console quick wins guide — same login, same half hour.

Orphan pages: the leak in most small sites

An orphan page has zero internal links pointing at it. It might be in your sitemap, it might even be indexed, but no visitor can reach it by browsing and no authority flows into it. Orphans happen innocently: a page gets removed from a menu during a redesign, a blog post predates your current template, a landing page was built for one email campaign and forgotten.

Three ways to find them, no paid tools

• Compare your sitemap to your navigation. Open /sitemap.xml and ask, for each URL: could a visitor reach this from the homepage by clicking? Anything you hesitate on is a candidate.
• Search Console → Links → Internal links. Sort ascending. Pages with zero or one internal link are your orphans and near-orphans. (New to the tool? Start with our Google Search Console guide.)
• Crawl it free: Screaming Frog’s free tier crawls up to 500 URLs, which covers almost every small business site, and flags orphans directly when you connect your sitemap.

For each orphan, decide: link it (add two or three contextual links from related pages), merge it (fold thin content into a stronger page and redirect), or delete it. Do not leave it floating.

How many internal links per page?

You will find dogma in both directions — “no more than 100” (an obsolete Google guideline from the 2000s) and “as many as possible”. The sensible answer for a small site: roughly 3 to 10 contextual links per page, placed where they genuinely help the reader, plus whatever your navigation adds. Two cautions worth keeping. First, the more links on a page, the less each one passes — so a page that links to everything emphasises nothing. Second, when two links on a page point to the same destination, Google primarily counts the first anchor, so make the first one descriptive.

Internal links also amplify everything else you do — a well-linked page with a sharp title compounds twice over, which is why this routine sits naturally beside our title tag CTR playbook.

And if the monthly routine is the part you know you will skip: Vantage agents do this continuously from your live Search Console data — spotting orphan pages, suggesting contextual links with descriptive anchors, and flagging new pages that nothing links to yet.
