Internal linking and topic clusters
Isolated pages chasing isolated keywords lost their value slowly and then all at once. What replaced them is depth, and the mechanism is your internal links.
That internal links drive discovery is documented. That dense topic clusters build authority is practitioner consensus, not something any platform publishes.
Isolated pages chasing isolated keywords lost their value slowly, then all at once.
What replaced them is depth — a library of interlinked pages covering a subject the way somebody who actually does the work would cover it.
The mechanism is your internal link graph. It's how pages get found, how authority moves between them, and how you state which things belong together.
What is topical authority?
It's the credibility a site earns by covering one subject thoroughly across many interlinked pages, instead of publishing one page per keyword.
The signal is structural. A dense, well-connected cluster describes a subject the way a practitioner would. A scattering of isolated pages doesn't. It's the practical reason to go deep on a few subjects rather than shallow on many.
The shape
A hub page introduces the subject and links to everything under it. Each page covers one aspect properly and links back up to the hub and sideways to its siblings. Defined terms link to the glossary.
That produces a dense, navigable cluster. A reader can go up for context or sideways for a related question. A crawler finds everything within a couple of hops. And the structure itself asserts that these pages are about one coherent subject.
The shape to avoid is the flat pile — thirty articles in a blog, each linking only to the blog index, nothing connecting any two of them.
Making it survive
Internal linking decays, because it's manual and nobody owns it. Pages get published and never linked from anywhere. Links point at pages that later moved.
The durable fix is to generate the structural links rather than type them:
- Breadcrumbs from the hierarchy.
- A cluster block on every page, listing its siblings automatically.
- Glossary auto-linking on the first mention of each term.
- A build check that fails on a dead internal link or an orphaned page.
That's what we do. Every breadcrumb, cluster block and glossary link on this site is generated from the content tree, and the build refuses to finish if an internal link doesn't resolve or a section has nothing under it.
None of those links can rot, because none of them was typed by hand.
Anchor text
Use text that describes where it goes. "Entity consistency" is useful to a reader and to a machine. "Click here" is useful to neither.
The old warning about over-optimized anchor text applies to inbound links from other sites, where repetitive commercial anchors look bought. Internally you control everything, so descriptive is simply better — just don't use the identical phrase for every link to the same page, which reads as mechanical.
What to do first
If you've got a flat pile of articles, don't start writing.
Group what exists by subject. Pick the group with the most pages. Write the hub page it's missing. Link it to every member, and add the links back.
That's usually an afternoon, and it does more than three new articles would.

Keyword placement
The most superstition-heavy topic in the field. Here's the small amount that holds up, and the large amount that doesn't.
Headings & structure
Most people pick heading levels by how big they render. They're a document outline, and the difference shows up for exactly the readers you care about.
Titles & descriptions
These are the only part of your page most people will ever see. A decade of advice about character counts has crowded out the one question that matters.
Depth & intent
Depth is not length. It is whether somebody who arrived with a question can leave without needing another page — and intent is the thing most content gets wrong before a word is written.
Readability & formatting
Readability tools count syllables and sentence lengths and hand you a grade level. Writing to that number produces prose that scores well and reads badly.
