Module 01 · Lesson 4 of 6
Site Architecture and Internal Links
Site architecture is the hierarchy your content actually lives in, not the one your navigation menu pretends to show. Two questions define it: how many clicks from the homepage does a page sit, and which pages link to which. Get those wrong and your best pages starve.
Depth and hubs
Pages near the homepage get crawled more often and inherit more of the site's accumulated importance. Pages buried six clicks deep get neither. The working pattern for content sites is hubs and clusters: a hub page for each topic (for example, a guide to AI SEO) linking out to its cluster pages (GEO research, citations, entities), and every cluster page linking back to the hub and to its siblings. The hub says "everything about this topic lives here"; the cluster pages prove it.
What internal links actually do
Three jobs at once. They let crawlers find pages. They pass authority within the site, from pages that have it to pages that need it. And they declare relationships: when a page about AI citations links to a page about query fan-out with a descriptive anchor, both pages read as part of the same topic. Links with generic anchors ("read more", "click here") do the first job and none of the others.
| Weak pattern | Working pattern |
|---|---|
| Blog posts link only to related posts by date | Every post links to its topic hub and one or two genuinely related posts |
| Money pages reachable only from the footer | Money pages in the main navigation and linked from relevant content |
| "Click here to learn more" | "Learn how to run a repeatable AI query set" |
| Orphan landing pages created for ad campaigns | Each landing page linked from a relevant section page or hub |
Boilerplate deserves a warning. Site-wide sidebars and footers linking the same twenty anchors on every page dilute relevance and rarely send meaningful authority. Put the important links in the content, where context exists, and keep boilerplate lean.
- Open a spreadsheet with two columns: URL, internal links pointing to it.
- For your top 20 pages, run a search for
site:yourdomain.comor use a free crawler, and count inbound internal links per page. - Sort ascending. Anything with zero or one inbound internal link is an orphan or near-orphan.
- For each orphan, decide: link it from its natural hub, or delete it. Do not leave it floating.
- Map your homepage's reachable structure: list what sits one click, two clicks, three clicks away. Stop at three.
- Identify your two most commercially important pages. Are they within two clicks of the homepage? If not, note where they sit.
- Fix two orphans or near-orphans: add one descriptive in-content link to each from its most relevant page.
- Rewrite two generic anchors ("learn more", "click here") into descriptive ones.
Why does depth matter?
A page is in the XML sitemap but has no internal links. What is the risk?
