Internal linking as a ranking lever

Everything else in search depends on somebody else. Links depend on other sites, rankings depend on competitors, and the algorithm is not yours.

Internal linking is entirely yours, and on most sites it is doing almost nothing.

What it actually does

Distributes authority. Whatever authority the site has arrived at specific pages, usually the homepage and a few posts that earned links. Internal links move it to the pages that need to rank and did not earn anything themselves.

Tells search engines what a page is about. The anchor text pointing at a page is one of the stronger signals about its subject, and it is a signal you write.

Creates a crawl path. A page with no internal links pointing at it is a page search engines may never find, regardless of whether it is in the sitemap.

Establishes topical relationships. A cluster of pages that link to each other reads as a body of work on a subject rather than as unrelated pages.

The structure that works

A hub page per commercial topic, and a set of specific pages that support it.

Every specific page links up to the hub with anchor text describing what the hub is about. The hub links down to the specific pages. The specific pages link sideways to each other where it genuinely helps the reader.

That shape concentrates authority on the page you want ranking commercially, while the specific pages pick up their own long tail rankings on the way.

What does not work is a flat structure where everything links to the homepage and nothing links to anything else.

Write the anchor text deliberately

The anchor text is the instruction. "Click here" is no instruction at all.

Use the phrase you want the destination page to rank for, written naturally into the sentence. Vary it across links rather than repeating the identical phrase thirty times, because a site with thirty identical anchors reads as manipulated rather than as helpful.

And make it match the destination. An anchor promising one thing that lands on another is a bounce, and bounces from internal links are a quality signal as well as a lost reader.

Links in body copy outweigh links in templates

A link in the navigation, the footer or a sidebar appears on every page and carries very little weight because of it.

A link inside the body of a relevant page carries more, because it is contextual. Which means the work is in the content rather than in the template, and it has to be done as the content is written rather than retrofitted later.

The practical habit: every new page links to at least three existing pages, and at least two existing pages are edited to link to the new one. That second half is the part everybody skips, and it is the half that makes the new page findable.

Find the pages with nothing pointing at them

Two audits worth running on any established site.

Orphan pages. Pages with no internal links pointing to them at all. They exist, they are in the sitemap, and nothing on the site refers to them. Common after a site migration or a redesign, and they almost never rank.

Pages with one link. Usually from a blog index that has paginated them off the first page, which means the only route to them is through a page nobody crawls deeply.

Fixing those two is frequently the fastest ranking improvement available on a site that already has content, because the content is already written and simply unreachable.

Then fix the direction of the flow

The last check is whether authority is going where the money is.

Most sites accumulate links on blog posts and then never pass that authority to the service pages that convert. A handful of deliberate links from the three or four most linked posts to the commercial pages they relate to moves real weight, costs an hour, and is the single highest return internal linking change on an established site.
