Every other lever in SEO depends on somebody else. Backlinks need another site to agree. Rankings need a search engine to agree. Internal links need nobody. You decide what points where, today, and the effect is real.
They do three jobs at once: they help crawlers find pages, they pass authority between pages, and they tell search engines what a page is about through the words you link with. Most sites get accidental value from them and leave the rest on the table.
Decide which pages you are actually promoting
Internal linking only works as a strategy if some pages are more important than others. If everything links to everything, you have said nothing.
Pick the small number of pages that need to rank: the ones that make money, or the definitive guides you want known for. Everything else exists partly to support them. That decision, written down, is the strategy. The rest is execution.
Hub and spoke, in plain terms
The structure that works is simple. One broad page covers a topic completely. Several narrower pages each cover one subtopic in depth. Every narrow page links up to the broad one, and the broad one links down to each narrow one.
That does two things. It concentrates authority on the page you want ranking for the competitive term, and it demonstrates to a search engine that you have covered the topic rather than mentioned it. Coverage is what earns a site the right to rank for the head term.
The spokes should also link sideways to each other where it genuinely helps a reader. Where it does not, leave it alone. A forced link is worse than no link.
Anchor text is the instruction
The words you link with tell search engines what the destination is about. This is the single most wasted opportunity on most sites.
- Describe the destination: link on the words that name what the reader will find
- Vary it naturally across pages rather than repeating one phrase everywhere
- Avoid click here, read more and this article, which describe nothing
- Never link a whole paragraph; link the phrase that carries the meaning
Find your orphans
An orphan page has no internal links pointing at it. It may sit in the sitemap and still be effectively invisible, because being linked from a real page is a much stronger signal than being listed.
Orphans accumulate quietly. A post published in a hurry, a landing page from a campaign that ended, a page whose category was later removed. Crawl your own site, compare the crawl against your full page list, and anything in the list but not in the crawl is an orphan. Either link it from somewhere sensible or remove it.
How many links is too many
There is no hard limit and the old hundred link rule is long dead. The practical limit is the reader's attention.
A useful test is whether a link would genuinely help someone at that exact sentence. Three to eight contextual links in a long post is normal. Twenty is usually a sign that links are being placed to distribute authority rather than to help anyone, and it dilutes each one.
Where the links should sit
Position affects weight. A link inside the body copy, in the flow of a sentence, counts for more than the same link in a footer or a sidebar that appears on every page.
Site-wide navigation is still valuable and does a different job: it establishes hierarchy. Use navigation for structure and body links for emphasis, and do not expect a footer full of links to substitute for either.
Link new posts backwards and old posts forwards
A new post is easy to link out from and has no links coming in. That is the wrong way round, because the new page is the one that needs help.
Build the habit into publishing. When a post goes live, find three older pages where it is genuinely relevant and add a link from each. It takes ten minutes and it is the difference between a post that gets discovered and one that waits.
An audit you can do in an afternoon
Once a quarter, run this and act on what it says.
- List your money pages and count internal links pointing at each
- Anything important with fewer than five inbound internal links needs more
- Find orphans and either link them or retire them
- Search your own site for click here and replace each with descriptive text
- Check that your best page on each topic links to every supporting page and back
Why this beats most of what you could do instead
Internal linking is free, immediate and entirely within your control. It requires no outreach and no approval. It is also cumulative: every post you publish adds another place from which to point at the pages that matter.
If you have an hour for SEO this week and no idea where to spend it, spend it here. It is the only part of the job where the answer to what is blocking me is nothing.
Common questions
- How many internal links should a page have?
- Three to eight contextual links in a long post is normal. There is no hard limit, but twenty is usually a sign links are being placed to move authority rather than to help a reader, which dilutes each one.
- What is an orphan page?
- A page with no internal links pointing at it. It may sit in your sitemap and still be effectively invisible, because being linked from a real page is a much stronger signal than being listed in a file.
- Does anchor text matter for internal links?
- Yes. The words you link with tell search engines what the destination is about, which makes click here and read more wasted opportunities. Link on the phrase that names what the reader will find.
