Internal Linking and Site Architecture
Internal linking is the only authority lever a site owner controls outright, and it needs no outreach and no new content. Ivan Sp audits how a site’s existing structure directs crawlers and link equity, and corrects the architecture before any new content gets built into it. A strong page buried deep in a weak structure underperforms regardless of what the page itself says.
Measuring Click Depth Site-Wide
Every important page gets checked against a three-click target from the homepage. Pages sitting deeper get flagged, because depth alone predicts how often a crawler visits a page and how much authority reaches it through internal links.
The check runs across the whole site rather than on a sample. Architectural faults tend to repeat by section, and a category with weak internal linking usually contains every page beneath it.
Finding Orphaned Pages
I list orphans first. An orphaned page carries no internal link pointing at it from anywhere on the site. It typically stays that way regardless of content quality. Pages published outside standard navigation, old campaign pages, and pages a redesign left behind are the usual sources.
Every audit enforces a no-orphan rule. A passing site has at least one internal link reaching every indexable page. Fixing the count is a linking exercise, and finding which pages qualify is the audit itself.
Auditing Silo Integrity
I audit silo integrity next. A silo keeps related content connected to its own category and limits links cutting across unrelated sections. The audit checks whether a site’s actual link graph matches its intended hierarchy, or whether links have drifted into a flat mesh over time.
Node-to-node linking is the specific fault the audit looks for, meaning a deep page linking straight into another deep page with no parent category ever introducing that relationship. It flattens the structure a silo exists to build.
Directing Existing Equity Where It Helps
Beyond structure, the audit maps which pages currently receive the most internal links and which receive almost none. The pattern is consistent across most sites. Authority pools on pages that were already strong, and pages that need support receive the least of it.
Recommendations point established, high-traffic pages toward new or underperforming pages deliberately. Existing strength gets concentrated where it changes an outcome, rather than left to accumulate passively.
Architecture Compared to the Tools That Build On It
This audit diagnoses the structure of a site as it exists today. An agent that proposes specific new links is covered under internal link discovery tools. Linking logic written into newly generated pages is covered under internal linking automation for generated templates.
Where the Standard Internal Linking Advice Breaks Down
- The usual advice
- Add more internal links to important pages, and put them in the footer so every page contributes one.
- What holds up in practice
- Placement decides most of the value, and a site-wide footer link is close to the weakest placement available. One contextual link from a closely related page usually carries more than a hundred footer links to the same destination.
Consider a firm that adds its priority service page to the global footer, gaining 300 internal links overnight. The inlink count in every audit tool triples.
Click depth does not change, because a footer link appears on pages already several clicks deep. The anchor text is identical 300 times, which describes the page once.
I measure click depth and anchor variety rather than link count. The number that moved was the one that mattered least.
The cost is a metric that looks improved in every report while the page stays exactly where it was.
Four Things Commonly Assumed About Internal Linking
How many clicks from your homepage is the page that makes you the most money?
Ivan Sp meets these four assumptions whenever internal linking is treated as a minor task.
| Commonly assumed | What actually holds |
|---|---|
| Internal linking is a minor optimisation. | Internal links decide crawl discovery, click depth, and how authority distributes. Few technical levers change more for less cost. |
| A footer link counts the same as a contextual link. | Placement carries most of the value. One contextual link from a closely related page typically outweighs a site-wide footer link. |
| More links to a page is always better. | Anchor variety and placement matter more than volume, and identical anchors repeated hundreds of times describe a page once. |
| Orphan pages are rare on a well-run site. | Orphans accumulate quietly from removed navigation, retired campaigns, and imported content. Most audits find them in the dozens. |
| Navigation links are enough structure. | Navigation creates a shallow path to a few pages. Contextual links are what connect a topic together and signal how pages relate. |
A page five clicks deep is competing with one hand tied, whatever it says. Moving it is a template change rather than a rewrite, and it is usually the cheapest win available.
Architecture Measurements
- Click depth
- The fewest clicks from the homepage to a page. Three or fewer is the usual working target.
- Orphan page
- A URL present in a sitemap or analytics with no internal link pointing to it.
- Inlink count
- How many internal links point at a URL, which is a direct signal of internal importance.
- Anchor text
- The visible words in a link, which describe the destination to both readers and crawlers.
- Silo integrity
- Whether links inside a topic stay inside it rather than scattering across unrelated sections.
- Where depth is reported
- The Crawl Depth column in a Screaming Frog crawl export.
- Where orphans are reported
- Screaming Frog crawl analysis, once a sitemap or analytics source is connected.
A Worked Example: A Service Page Five Clicks Deep
Consider a 300-page firm whose highest-margin service page sits behind a dropdown and a paginated listing. The figures below are illustrative and show how the numbers move together. They are not drawn from a client engagement.
| Measurement | Before | After restructuring |
|---|---|---|
| Click depth from homepage | 5 | 2 |
| Internal links pointing at the page | 3 | 34 |
| Descriptive anchors rather than read more | 0 of 3 | 31 of 34 |
| Days between Googlebot visits | 38 | 9 |
| Orphan pages site-wide | 47 | 0 |
I changed no words on the service page itself. The page moved because the structure around it changed, and crawl frequency followed the structure.
Think of internal links as signposts inside a building. Adding a floor directory beside the lift does not renovate the office on the fifth floor, and it does decide how many people find it.
Anchor text carries the second half of the effect. Thirty-four links reading read more describe nothing, and thirty-four links naming the service describe it thirty-four times.
How an Architecture Audit Runs
I follow the order below, since orphan detection depends on the crawl finishing first.
- Crawl the full site, and connect the XML sitemap and analytics source before starting the crawl.
- Run the crawl analysis step, which is what populates orphan and link score data.
- Export the Crawl Depth column, and list every commercially important page deeper than three clicks.
- Export the inlink count per URL, then compare the ranking against the pages that actually earn revenue.
- List every orphan page, and decide for each whether it deserves a link or deserves removal.
- Audit anchor text across the site, and flag every generic anchor such as click here or read more.
- Map which sections link across topics, and identify links that dilute a silo without helping a reader.
- Add contextual links from high-authority pages to the underlinked pages identified in step four.
- Rewrite generic anchors to four to eight descriptive words naming the destination.
- Re-crawl 30 days later, and confirm click depth and inlink counts moved as specified.
How This Work Is Scoped
I scope architecture work against template count rather than page count, since most fixes land in templates.
- What arrives
- A depth and inlink report, an orphan list, an anchor text audit, and a specific linking plan.
- Typical duration
- Two to three weeks for a site under ten thousand URLs.
- What the client supplies
- CMS access for template changes, plus Search Console and analytics access.
- Included
- Audit, the linking specification, anchor text rewrites, and a verification crawl.
- Not included
- Navigation design, front-end development, and information architecture for a site rebuild.
- What changes the estimate
- Faceted navigation, several thousand orphans, or a headless front end.
- How it is quoted
- After a short scoping call, once the crawl size and template count are known.
Tools and Primary Sources
The references below define the measurements named above. Each opens in a new tab.
- Screaming Frog SEO Spider reports crawl depth, inlinks, anchor text, and orphan pages in a single export.
- Google internal link guidance sets out what makes a link crawlable and why anchor text matters.
- Google site structure guidance covers navigation, hierarchy, and how a crawler discovers pages.
- Ahrefs Site Audit reports orphan pages and internal link distribution from its own crawler.
Test Your Own Structure in Five Minutes
I suggest a manual test that needs nothing but a browser.
- Open your homepage in a private window, so no personalisation or history helps you.
- Pick the service or product that earns the most revenue.
- Click toward it without using search or the address bar, and count the clicks.
- On arrival, use your browser find function to search other pages for that page’s exact name.
Four or more clicks means the page is structurally buried whatever its copy says. Few mentions elsewhere on the site means almost nothing internally points at it.
Common Questions
How is a site architecture audit different from an internal link discovery tool?
This audit diagnoses the structure itself: click depth, silo integrity, and where equity currently pools. The discovery tool works from that diagnosis to propose specific new links between specific pages.
Does site architecture matter for a small site?
Less urgently than for a large one, since a 40-page site rarely develops deep orphaned sections. The audit still catches navigation gaps and misdirected equity that a small site can otherwise carry for years unnoticed.
Can fixing architecture alone improve rankings without new content?
Often yes, because reaching pages that already existed but were poorly connected is a comparatively fast fix. Results depend on whether the underlying pages were being suppressed by structure or by content quality.
Does adding more internal links always help?
No. Link volume matters less than placement and anchor text. A footer link gains far less than a contextual link from a closely related page. Indiscriminate linking also dilutes the topical grouping a silo exists to hold.
