Internal linking is the practice of linking between pages on your own site. It helps search engines discover and understand relationships between pages, distributes authority across a site, and guides visitors toward relevant content. It is one of the few ranking levers fully within your control.

Internal linking is entirely under your control, costs nothing, and is routinely neglected. It is how a cluster of content becomes more than the sum of its pages, because each page reinforces the others and signals depth on a topic. If you have published a lot of content that is not linked together, you are leaving earned authority stranded.

Example:

A set of related pages linked to each other and to a central pillar signals genuine depth on a topic. The same pages published in isolation signal nothing.

Why does internal linking matter?

It helps search engines understand relationships between pages, distributes authority across the site, and signals topical depth, all within your own control.

How should internal links be written?

With descriptive anchor text that reflects the destination page's topic, rather than generic phrases, since the anchor carries semantic meaning.
