Internal linking: the rules to structure a site that ranks and gets cited

Internal linking refers to all the links that connect the pages of a single site. Well designed, it lets Google discover every page, understand the hierarchy of topics and identify the reference page for each intent; it also helps generative engines find and cite the right answer. This guide sets out the rules to structure a site that ranks and gets cited, derived from the semantic cocoon: which pages link to which, with which anchors, where, and how to plan and check the whole.

What an internal link is for

An internal link connects two pages of the same site. At the time of writing, Google uses it for four distinct purposes, and each one calls for a different decision:

• Discovering pages: the bot follows links; a page that no link reaches risks remaining uncrawled.
• Understanding hierarchy: the page that every page on a topic links to appears as its reference.
• Understanding meaning: the anchor text and the sentence around it indicate what the target page promises.
• Distributing internal authority: each link passes a share of the source page's authority to the target page.

Readers follow the same logic as the bot. A link placed at the moment they ask themselves a question helps them; a link added just "for linking's sake" interrupts them. Good internal linking serves reading first, and the signals sent to search engines follow from it.

Internal PageRank: what can be said, what cannot be measured

PageRank is Google's historical model: a page gains popularity via the links pointing to it and passes part of it on through its own links. Applied to a single site, it becomes internal PageRank, which the industry also calls "link juice". The image is only an image: authority does not flow like a liquid; it results from a calculation Google does not publish.

Google has not displayed a public PageRank score since 2016, so internal PageRank cannot be measured. You observe its indirect effects, by page group, in Google Search Console: crawling, indexing, impressions, rankings.

That is why the Incremys doctrine rules out PageRank sculpting, i.e. attempting to distribute authority by manipulating links. Three practices follow:

• you never add or remove a link to "steer" authority;
• you never put a nofollow attribute on an internal link: if the page does not deserve a followed link, it does not deserve a link;
• you never hide a link (obfuscation) to show the bot a different structure from the one readers see.

Linking rules by page type

A cocoon covers one topic, with a pillar (T0) covering it broadly and zooms (T1, sometimes T2) each handling a specific intent: 2 levels, 3 at most. The parent links to all its children, each child links to its parent, and siblings link to each other when the reader needs it. A target page receives only one link per article.

Links by page type at a glance

The following table applies these rules to the five most common page types on a B2B site:

Every useful page must remain reachable from its cocoon's pillar in a few clicks. No number sets this distance: a page reachable only through pagination or the internal search engine is too far away.

Structural links vs contextual links

Navigation links matter, but they do not replace links placed in the body text. They play three complementary roles:

• the menu gives access to pillars and offer pages from any page;
• breadcrumbs show the hierarchy and let every page link back up to its parent;
• the footer gives access to cross-cutting pages, without carrying any precise meaning.

The contextual link, by contrast, carries meaning: its anchor and its sentence say why the target page answers the question. A page connected only through navigation exists for the bot, without Google knowing what it promises.

One pillar per offer on a B2B site

On a services site, the most readable structure groups pages that link to each other around each offer:

• the offer page, which describes what the client buys;
• an editorial pillar, which frames the topic and links to all its zooms;
• zooms that answer objections and method questions;
• a dedicated FAQ, which gives direct answers.

Articles link to the offer page when the reader's intent shifts towards evaluation, not in every paragraph.

Anchors and link placement

A useful link combines an anchor that describes the target page and a placement that matches the reader's need.

Writing descriptive anchors

Anchor text is the clickable text of a link. It tells the reader and the search engine what the target page promises. Five rules govern how you write it:

• descriptive: it announces the content of the target page (“the six steps of an internal linking audit”);
• varied: two articles linking to the same page do not use the same wording;
• natural: it fits into the sentence without twisting it;
• never generic: “click here”, “find out more” or “this article” provide no information;
• never the exact keyword repeated: the same phrase used everywhere is over-optimisation.

Two different pages never receive the same anchor. If “SEO audit” points sometimes to an offer and sometimes to an article, Google can no longer tell which one answers the intent. For links on images, the alt attribute acts as the anchor.

Placing links where the question arises

Where a link sits matters as much as its anchor. In an article, links are distributed according to four principles:

• in the body, in the paragraph where the reader asks the question the target page answers;
• one link per target page per article, at the first place where it is useful;
• a “Depending on your situation” block at the end of the article, which guides readers according to their profile;
• navigation (menu, breadcrumbs) as a complement, never as a replacement for body links.

A link tucked into a generic list at the bottom of the page does little: readers who get there have already found or abandoned their answer.

Internal and external linking: two distinct levers

Internal linking connects your pages to each other. External linking refers to links exchanged with other sites, above all backlinks, the links other domains point to yours. Both contribute to a page's authority, but they are not managed the same way.

What sets the two levers apart

The following table compares the two levers on the criteria that drive decisions:

Why one lever does not compensate for the other

A backlink rarely points to an offer page: it tends to target a guide, a study or an article. That link remains under-used when the internal structure does not connect the page receiving it to the rest of the topic. Three cases come up repeatedly:

• the page receiving the backlink links neither to its pillar nor to the relevant offer page;
• the page is reachable only through a filter or the internal search engine;
• its links point to secondary pages rather than to the logical next step of the question.

Internal linking matters all the more because 94–95% of pages have no backlinks at all (Backlinko, 2026): for them, internal links are the only source of authority. So you start with a clean internal structure, then work on acquisition for the pages able to serve the rest of the site, following a structured link building method.

The linking plan: decide before you publish

Without a plan, internal linking drifts: the first pages published accumulate links and new ones remain isolated. The linking plan sets the decisions once, then has them applied at every publication.

The five steps of the plan

The plan is built in five steps, each assigned to an owner and closed with a deliverable:

The cocoon map rests on a simple rule: one page per intent. Two pages answering the same question compete for the query; you merge or differentiate them before adding a link. To build this map, follow our method to create a semantic cocoon.

The page → links matrix

The matrix is the plan's reference document: a spreadsheet in which each row describes a link to add. To keep it usable, each row records:

• the source URL and the target URL;
• the relationship and the objective (parent, child, sibling; discovery, proof, move to the offer);
• the link type (contextual, breadcrumb, navigation, end-of-article block);
• the planned anchor and its accepted variants;
• the intended placement on the page and the deployment priority.

Deployment happens in batches: obvious fixes first, then pillars and high-stakes pages, then long-tail zooms. Each batch is measured separately.

The brief: links to add before writing

The internal linking of new content is decided in the brief, not after publication. Every brief contains a “links to add” section that specifies:

• the link to the parent (pillar or zoom);
• the links to all its children, if it is a pillar or a T1 zoom;
• useful siblings and pages outside the cocoon, with the section where they go;
• the existing pages that must link to the new content, with the proposed anchor.

The last point prevents orphan pages. SEO copywriting best practices complete this brief for the rest of the content.

Governance: who decides, who adds, who checks

A linking plan withstands the site's growth when three roles are assigned. One person can hold two of them, provided checking stays separate from adding links:

• The plan owner sets priorities, approves exceptions and maintains the cocoon map.
• The content owner builds the links into every brief and keeps the matrix up to date.
• The execution owner adds the links, fixes broken links and redirects, then checks.

An exception is justified in one sentence beginning “this link helps the reader to…”. If the sentence does not come, the link does not belong.

When the wrong URL ranks

Google sometimes ranks a blog article for a query that an offer page should hold, or a zoom instead of its pillar. Correcting this targeting is called SERP realignment.

Signals of a poor URL target

In Google Search Console, the performance report shows which URL receives impressions for a query. When it is not the right one, three causes dominate:

• several pages cover the same intent, and Google hesitates between them;
• the target page receives few internal links, or links with vague anchors;
• the page that ranks receives more internal links, with anchors close to the query.

The four realignment actions

The fix comes through additions and clarifications, never through removing links to “starve” a page of authority. In order:

• Clarify the target page: title, H1 and opening paragraph explicitly state the intent it must hold.
• Add links to the target page from the pages on the topic, starting with those that receive traffic.
• Align the anchors: links aimed at this intent use consistent anchors that describe the target page.
• Clarify the page that ranks by mistake: refocus it on its own intent and add a link from it to the target page.

If the two pages genuinely answer the same question, you need to merge or differentiate them. Our article on search intent helps you decide. The same work benefits generative engines, which are more likely to cite a page whose promise is clear.

The most common internal linking mistakes

Most defects come from links added without a plan or from settings inherited from old practices. The following table matches each mistake with its effect and its fix:

To spot these mistakes, our six-step internal linking audit method details crawling, graph modelling, depth measurement, anchor checks and the crawl vs index gap. It results in an action plan prioritised by impact and effort.

Internal linking and AI citability

Generative engines (ChatGPT, Perplexity, Gemini, AI Overviews and AI Mode, available in France since summer 2026 at the time of writing) rely on pages they can reach and whose structure is readable. An orphan or deeply buried answer page has little chance of being found, and therefore of being cited.

Organic ranking is not everything: 60% of AI citations come from URLs outside the organic top 20 (State of AI Search, 2025). A precise zoom, linked to its pillar, can therefore be cited without dominating the main query. Other benchmarks are gathered in our GEO statistics.

Three linking habits directly support AI citability:

• every important question has its own answer page, linked from its topic's pillar;
• anchors describe the answer the page provides;
• pages that resemble each other are merged or differentiated.

Internal linking guarantees no citation: you observe correlations by page group, never a demonstrated causal link. For the full set of levers, see our guide to Generative Engine Optimization (GEO).

Depending on your situation

Depending on your starting point, the logical next step differs:

• You are preparing a redesign or taking over an existing site: start with a full SEO audit before redrawing the links.
• You want to check what Google sees of your links: our Google Search Console guide covers the Links, Pages and URL Inspection reports.
• You manage a catalogue: categories, facets and product pages follow their own rules, detailed in our e-commerce SEO guide.

Before building your plan, the 360 audit module of the Incremys GEO & SEO platform maps your keywords and pages, spots orphan pages, measures the depth of every page and shows your AI presence by keyword.

FAQ on internal linking

How many internal links should a page have?

There is no quota. A page contains the links the reader needs: its parent, its children, siblings and pages outside the cocoon that are useful to its question. The same target receives only one link per article. A link that answers no question does not belong, whatever the total.

How do you choose internal link anchor text?

Choose a descriptive anchor that announces what the target page promises, fitted naturally into the sentence. Vary the wording from one article to another, avoid “click here” and do not repeat the exact keyword everywhere. Two different pages never share the same anchor.

Should internal links be set to nofollow?

No. A nofollow internal link does not help the target page and benefits no other page. The practice belongs to an old PageRank sculpting logic, which the Incremys doctrine rules out. If a page does not deserve a followed link, do not link to it, or ask yourself whether it belongs on the site.

Are breadcrumbs enough to link a site?

No. Breadcrumbs show the hierarchy and let readers go back up to the parent. They say nothing about the precise meaning of each page or the relationships between sibling pages. Contextual links, placed in the body text with a descriptive anchor, remain essential.

What is an orphan page?

An orphan page receives no links from the site's other pages. The bot struggles to discover it and it receives no internal authority. It is a defect to fix by linking to it from its parent, or a sign that it does not belong on the site.

Does internal linking help you get cited by AI?

Yes, indirectly. Generative engines rely on pages that are reachable and well structured. An answer page linked to its pillar, with anchors that describe what it provides, is more likely to be found. Internal linking guarantees no citation: you measure correlations, not causation.

Internal linking or link building: where should you start?

Start with internal linking. You control it entirely, it works faster and it determines the effect of backlinks: an external link to an isolated page does little for the rest of the site. Then focus acquisition on pillars and reference content.

How often should you review your internal linking?

On three cycles. At every publication, add the new page to the plan, with its inbound and outbound links. Every month, check priority pages: links received, anchors, the URL that ranks. Every quarter, review the whole site: orphan pages, broken links, redirects.
