Internal Linking Is the Cheapest Ranking Lever Nobody Owns
Why the cheapest lever is the one nobody pulls
Internal links cost nothing, require no approval, need no outreach and are entirely within your control, which by any reasonable prioritisation should make them the first thing anybody fixes. They are instead the last, because there is no tool that reports them as broken and no stakeholder who asks about them.
The distribution on a typical site is badly lopsided: the most recent content is the best connected, because whoever wrote it remembered what else existed, and the oldest is orphaned. That is the inverse of what you would choose if you were allocating attention deliberately.
It needs no new content, no budget and no outreach, and most sites still do it by accident.
Why it gets neglected
Nobody is responsible for it. Writers link to whatever they remember. Developers build navigation. Nobody maps the whole site and decides where authority should flow.
The result is important pages sitting four clicks from the home page with three links pointing at them.
Doing it deliberately
Start from a complete page inventory. Group pages into topics. Decide which page should be the strongest for each topic. Then link from the supporting pages to it, with anchors that describe the destination.
Pick up orphans along the way. They are usually pages someone cared about once.
What changes
Crawl depth drops, relevant pages rank better, and readers follow the path you intended rather than the one the menu happened to create.
Finding the pages nobody links to
Crawl your own site and count inbound in-content links per page, excluding the navigation and the footer, because a link that appears on every page tells a search engine nothing about which page matters. The distribution is almost always worse than anybody expects: a handful of pages with dozens, a long tail with one or none, and the ones with none are frequently the pages the business most wants to rank.
The reason is structural rather than negligent. Links get added when somebody writes a new page and remembers what else exists. Nobody goes back to the older pages to link forward, so the newest content is the best connected and the oldest is orphaned, which is the exact inverse of what age-based authority would suggest.
A pass that takes an afternoon
- List pages by inbound in-content links, ascending.
- For each of the twenty worst, find three existing pages that genuinely discuss the subject.
- Add the link inside a sentence that would have been written anyway, with descriptive anchor text.
- Never add a link that a reader would not want to follow, because that is how a rail of irrelevant links gets built.
- Re-crawl and confirm nothing is left on zero.
Exact-match anchors everywhere
Repeating the same exact phrase as the anchor on forty links reads as manipulation and, worse, removes the information a varied anchor carries. Anchor text is a description of the destination, so varying it naturally describes the page more completely than one phrase repeated.
Common questions
Do navigation links count?
Less. A link present on every page distributes evenly and so distinguishes nothing. In-content links are the ones that say this page is relevant to that one.
How many internal links per page?
No useful number exists. The test is whether each one is somewhere a reader would plausibly want to go next.
Should we link to the same page repeatedly?
Once per page, from the most relevant sentence, is enough. Three links to the same destination in one article add nothing.
Does link position on the page matter?
In-content links in the body are worth more than a rail at the bottom, which is worth more than a footer. Position correlates with whether a reader would use it.
