How Should Internal Links Be Used and Written?
Internal linking is the cheapest lever in SEO and the most consistently underused. It requires no budget, no outreach and no developer.
It is also the clearest statement you can make about your own site: these pages matter, and this is how they relate.
This guide covers how internal links work, how to choose anchor text, where to place links, and the mistakes that turn a helpful structure into an over-optimised one. It assumes you know how SEO works at a high level.
Key takeaways
- Internal links distribute relevance and define topical relationships.
- Anchor text should be descriptive and varied, never identical everywhere.
- Links in body copy carry more weight than footer or sidebar links.
- Keep commercially important pages within three clicks of the homepage.
- Orphan pages receive minimal crawl attention and rarely rank.
- Link where a reader benefits, not to a fixed quota per page.
Why do internal links matter so much?
They do three jobs at once, which is unusual for something that costs nothing.
- Discovery: they are how search engines find pages in the first place.
- Importance: heavily linked pages are treated as more significant.
- Meaning: anchor text and context describe what the destination is about.
- Navigation: readers follow them toward a decision.
Example. A service page stuck around position 14 for a year moved into the top five within six weeks after eleven existing articles were given contextual links to it. Nothing on the page itself changed.
How should anchor text be written?
Anchor text should describe the destination in the words a reader would naturally use. Variation matters as much as accuracy.
| Pattern | Example | Use |
|---|---|---|
| Exact match | local SEO services | Sparingly — once or twice per destination |
| Phrase match | our approach to local SEO services | Frequently |
| Partial match | how we handle local search | Frequently |
| Descriptive | the way we run local campaigns | Frequently |
| Branded | Undeniable Growth | Occasionally |
| Generic | click here | Avoid — describes nothing |
If forty pages all link to one destination with the same exact phrase, the pattern reads as manipulation rather than helpfulness. Vary it.
Where should links be placed?
Position affects both weight and usefulness. A link nobody reads does little.
- In body copy, inside a sentence that gives the link context.
- High on the page for the most important destination.
- At the point where the reader would naturally want more detail.
- Not clustered into a block of links at the bottom.
- Not duplicated repeatedly to the same destination within one page.
Navigation and footer links still help discovery, but a contextual link inside relevant text is worth considerably more.
How should a site's link structure be organised?
The reliable model is a hub and spoke arrangement: a broad page for each topic, with detailed pages linking up to it and to each other where relevant.
- Hub pages link down to every page in their cluster.
- Detail pages link up to their hub, high in the copy.
- Detail pages link sideways where the topics genuinely relate.
- Commercial pages receive links from supporting guides.
- Nothing important sits more than three clicks from the homepage.
This structure also makes your topical coverage legible, which supports both traditional rankings and AI systems assessing expertise.
How many internal links should a page have?
Enough to be useful, which usually means between three and ten in a substantial article.
- Every link should be one a reader might genuinely follow.
- Quotas produce forced links, which help nobody.
- Longer pages support more links because they cover more ground.
- A page with none is a dead end and a wasted opportunity.
The better question is whether each important page has enough inbound links, not whether each page has enough outbound ones.
What are the common internal linking mistakes?
- Identical exact-match anchors everywhere — reads as over-optimisation.
- Related-posts blocks only — automated, contextless, low value.
- Orphan pages — no inbound links, so barely crawled.
- Linking only from new content — older pages often carry more authority.
- Links to redirected URLs — update them to the final destination.
- Every link at the bottom — placement outside the reading flow.
The last two are quick wins on almost any site that has existed for more than a couple of years.
How do you audit internal links?
You can do a useful pass without specialist tools.
- List your commercially important pages.
- For each, search your site for pages mentioning the topic.
- Check whether those pages link to it, and how.
- Add contextual links where they are missing, varying the wording.
- Note the anchors used, so you do not repeat one phrase everywhere.
Search Console's Links report shows internal link counts per page, which quickly identifies neglected pages.
How do internal links help pages that are close to ranking?
They are usually the fastest available intervention for a page stuck between positions 8 and 25.
That page is already considered relevant. Additional internal links from related content increase its perceived importance without requiring new content or outreach.

Frequently asked questions
Do internal links pass authority like backlinks?+
They distribute the authority a site already has rather than adding to it. That distribution is why internal linking changes which of your pages rank, sometimes dramatically.
Should I use exact-match anchor text?+
Occasionally. Once or twice per destination is natural; using the same exact phrase across dozens of pages looks engineered and can suppress the effect.
Are footer links useful?+
For discovery and navigation, yes. For relevance, far less than a contextual link inside relevant body copy, because they appear identically on every page.
How many clicks from the homepage is too many?+
Beyond three or four clicks, crawl frequency and perceived importance drop noticeably. Important pages should be reachable in two or three.
Should older articles be updated with links to new ones?+
Yes, and this is one of the highest-value habits available. Older pages often carry more accumulated authority, so linking from them helps new pages establish themselves faster.
The habit worth building
Every time you publish, add links to the new page from three existing ones, using different wording each time. Every quarter, check that your commercial pages have inbound links from everything relevant.
That routine costs almost nothing and consistently outperforms far more expensive activity.
