Internal linking
Linking your own pages to each other to pass authority and help readers and crawlers move between related content.
In depth
What it really means
Internal linking connects your own pages. Those links help readers find related content, help crawlers discover and understand pages, and pass ranking authority from strong pages to the ones you want lifted.
It is the highest-return work in SEO that nobody schedules, because you control it completely. No outreach, no approval, no budget. A well-linked site behaves like an organized library. A poorly linked one buries its best work three clicks deep where nothing finds it.
Two rules worth memorizing
1. Click depth: every page that matters should be reachable in three clicks from the homepage. Pages deeper than that get crawled less often and rank worse, independent of their quality.
2. Link volume: three to eight contextual internal links per 1,000 words. Below three, the page is isolated. Above ten, each link carries less weight and the copy starts reading like a directory.
Anchor text, what works
| Do | Do not |
|---|---|
| “our guide to topic clusters” | “click here” or “read more” |
| Vary the phrasing across pages | Use the identical exact-match anchor on 40 pages |
| Name the destination topic | Name your brand when the destination is a concept |
| Link from inside body copy | Rely only on a Related list at the bottom |
Pros & cons
Pros
- Fully within your control, unlike backlinks.
- Moves authority from your strongest pages to the ones that need it.
- Helps crawlers and AI engines understand which page is central to a topic.
- Keeps readers moving toward conversion instead of back to the results page.
Cons
- Degrades silently. Links go stale and orphan pages accumulate as the site grows.
- Too many low-relevance links dilute the signal and irritate readers.
- Requires ongoing maintenance that nobody owns by default.
The mistake people make
Only linking forward. Teams add links from new posts to old ones and never go back to link from the old high-authority posts to the new page that needs help. The authority you want to move sits in pages published two years ago. Every time you publish, spend ten minutes adding two links from your strongest existing pages into it.
Best practices
- Link every new post up to its pillar and across to close siblings.
- Add links from established pages down to new ones, not only the reverse.
- Use descriptive anchor text that names the destination topic.
- Find and fix orphan pages quarterly with a crawler.
- Keep important pages within three clicks of the homepage.
- Link because it helps the reader. A link nobody would click passes little of value.
FAQs
Why is internal linking important?
It moves authority between your pages, helps crawlers understand your structure, and guides readers toward conversion. It is also free.
How many internal links per page?
Three to eight contextual links per 1,000 words is a workable range. Relevance matters more than the count.
What is an orphan page?
A page nothing links to. Crawlers find it slowly, readers never find it, and it almost always underperforms.
What anchor text should I use?
Descriptive text naming the destination topic. Vary the phrasing rather than repeating one exact-match anchor site-wide.
Does internal linking help AI visibility?
Yes. Clear structure helps AI engines work out which page you are the authority on and how your topics relate.
