Internal Linking Checklist: How Internal Links Help a Page Rank

Work through this internal linking checklist and you will have covered the part of search optimisation you control most completely. Internal links — links between pages on your own site — cost nothing, need no one’s permission, and decide which of your pages search engines find, how well they understand them, and where your site’s authority flows. Most small sites barely use them on purpose. Pages are published, menus are set, and the linking between the actual content is left to chance.

How internal links help a page rank

Internal links do three jobs. Discovery: search engine crawlers move through a site by following links, so a page nothing links to is a page that may be crawled rarely or not indexed at all. Context: the words you link from — the anchor text — describe the destination page to the search engine, reinforcing what that page should rank for. Authority flow: links pass ranking signal around a site, so your most-linked, most-visited pages can share their strength with newer or commercially important pages that need it. Readers benefit in parallel: a well-placed internal link is simply the next useful thing to read, which is the standard every item below is written to.

The internal linking checklist

• 1. Every important page has at least one internal link pointing to it. Pages with none are orphans. Find them with a site crawl or your SEO tooling, and link each one from a relevant page — starting with the pages that matter commercially.
• 2. New content is linked from older content, and links back. When you publish a post, add links to it from two or three relevant older pages, and link from the new post to the older material it builds on. Publishing without this step leaves the new page to be discovered by luck.
• 3. Anchor text describes the destination. Link from words that say what the reader gets — “our guide to briefing a copywriter” — not “click here” or “read more”. The anchor is information for readers and search engines alike.
• 4. Anchors vary naturally. Do not link to the same page with one identical, keyword-loaded phrase from everywhere. Varied, descriptive anchors read as editorial choices; repeated exact-match anchors read as manipulation.
• 5. Your strongest pages link to the pages you want to rank. The homepage, popular posts and well-linked guides hold the most authority to share. Point some of it deliberately at the service pages and posts you want found.
• 6. Clusters link together. A pillar guide and the posts supporting it should link to each other in both directions. This is the working form of an internal linking strategy: structure that shows a search engine the shape of your expertise. It starts with the copy itself — our explainer on what SEO copywriting actually means covers the page-level groundwork.
• 7. Blog posts link to the service pages they relate to. Informational content earns the visit; service pages convert it. A post that never points at the relevant service wastes the journey — as our list of SEO copywriting mistakes notes, it is one of the commonest ways good pages stay invisible.
• 8. No internal link is broken or routed through a redirect. Links to pages that error, or that bounce through redirects, waste crawl effort and authority. Link directly to the final URL and fix the stragglers.
• 9. Important pages sit within three clicks of the homepage. Depth is a signal of unimportance. If a page you care about takes four or more clicks to reach, shorten the path.
• 10. The count stays sensible. Enough links to be useful, not so many that the page becomes a directory. If everything is linked, nothing is emphasised.

Anchor text: internal linking best practices

Write the anchor you would want as a reader: specific enough to predict the destination, honest about what is there. Keep anchors in the flow of the sentence rather than appended as a list of links at the end. And treat nav and footer links as structure, not strategy — the links that carry weight are the contextual ones inside the content, surrounded by relevant text.

Mistakes that waste internal links

The patterns to avoid are the mirror of the checklist: publishing posts that link nowhere; linking every page to the homepage with the same phrase; stuffing links between unrelated pages because the keywords matched; and setting the structure once and never auditing it again. Each is cheap to fix and expensive to leave. Link structure is one of the things examined in our technical SEO audit, and keeping it healthy month to month is part of managed SEO — but the checklist above is deliberately written so a site owner can run it in an afternoon, because most of its value is in doing it at all.

Frequently asked questions

How many internal links should a page have?

There is no correct number. Link where it genuinely helps the reader reach the next useful page, and stop there. A focused post might carry three to five internal links; a long pillar guide will naturally carry more. Relevance is the rule — links added to reach a quota help nobody, and readers and search engines can both tell.

Do internal links really affect rankings?

Yes. Internal links control whether crawlers discover and index your pages at all, they pass ranking signal from stronger pages to weaker ones, and their anchor text tells search engines what the destination page covers. They cannot rescue a page with nothing worth ranking — but they decide whether good pages get found, understood and credited.

What is an orphan page?

A page with no internal links pointing to it. Readers cannot reach it through the site, and crawlers may only find it via the sitemap or a direct URL visit, so it is crawled less and ranked weaker than it should be. Every important page needs at least one relevant internal link; orphans are the first thing this checklist exists to find.

How often should I audit internal links?

Run a light check after any publishing push, redesign or URL change, and a fuller audit periodically — quarterly suits most small sites. Links break and structures drift as a site grows; regular small passes catch orphans and dead links before they accumulate into a visibility problem.
