Internal Linking Strategy: How to Build Topical Authority in 2026

Every page on your site. Strengthens or weakens the pages around it depending on the way the page links. A strong internal linking strategy tells search engines what your site is actually, about. It moves authority toward the pages you want to rank the highest. It also helps readers find content without hunting through navigation. Let me walk you through the mechanics that make that work: anchor text, site architecture and how link equity actually moves between pages. For the wider on-page picture this fits into, see the complete on-page SEO guide.

Internal linking strategy is the deliberate practice of connecting pages within a website using descriptive anchor text so that link equity and topical relevance flow toward the pages that matter most.

Internal link anchor text

Descriptive and diverse anchor text is more effective than generic language as it provides the crawler and end user with a clear indication of the content on the page they are clicking through to, rather than a link to uncertainty. Google‘s own link best practices share that the anchor text which shows and describes the link to the edge crawler must be descriptive, less than 20 characters long, relevant to the target page and it can only crawl the link if we use a real <a> element with we cannot use JavaScript links that do not actually function as links:

A practical anchor text mix: roughly 15–25% exact-match anchors (the literal target keyword), 30–40% partial-match (a natural variation), and the remainder semantic variants that describe the topic without repeating the exact phrase. This distribution avoids two failure modes at once — generic anchors like “click here” that pass no topical signal, and over-optimized exact-match anchors on every single link, which reads as manipulative rather than natural.

The anchor text for title tags that rank in the previous sentence is a working example: it describes the destination specifically, reads naturally in the sentence, and avoids repeating “title tag optimization” verbatim everywhere it’s linked from across the site.

Silo structure SEO

A silo organizes a site into separate topic groups, in which pages within a silo are self-referential and connect to each other often without linking to other topics. This works well for multi-topic sites that want to rank for genuinely distinct keyword clusters without one topic diluting another’s relevance signal.

Trade-off is flexibility. Building a rigid silo blocks (or at least in my experience discourages) natural cross linking of related topics that end up separated to make the silo, which can leave real useful interrelations missing entirely. Sites with narrower focus at least on some overlap often benefit from a looser hub-and-spoke rather than a sudden wall between proximate content in a stronger silo3.

Silos work best when a site covers several genuinely separate subjects — an e-commerce site selling both electronics and furniture, for instance — rather than one subject with many related facets, where hub-and-spoke tends to fit better.

Internal linking best practices

Link contextually, from within body content, rather than relying only on navigation and footer links. In-body links carry more weight because they sit inside the topical flow of a sentence, giving search engines a clear signal about why the two pages are related — a footer link that appears on every page of the site carries no such context.

Keep every important page reachable within three clicks of the homepage. Pages wedged below that will be crawled less frequently; they will also retain a smaller proportion of link equity, as each ‘hop’ between pages reduces the power flowing to the target page. As a rule of thumb, somewhere in the region of 2–5 contextual internal links per 1000 words of body copy will help support page CPC, although this should be viewed as a guideline rather than a definitive directive.

Audit for orphan pages regularly. A page with no incoming internal links is difficult for both crawlers and readers to find, no matter how good the content is. This same silo demonstrates the fix in practice: this article links to both meta description best practices and the title tag guide above, ensuring neither sibling page depends solely on the pillar for its internal links.

Hub and spoke model

The hub-and-spoke approach is where one central dividing pillar page (the hub) links out (and is linked to by) a number of narrower cluster pages (the spokes) which cover related sub-areas. That is how this particular silo has set-up: we have one on-page SEO pillar that links out to cluster pages in title tags, meta description and internal linking; and each cluster links back to the pillar.

Contrast with a strict silo, though; an hub-and-spoke structure also allows for spokes to connect with each other if the connection makes sense such as this page linking to its meta description and title tag siblings. That‘s the kind of cross-spoke linkage since the three topics are all related to the same general topic without forcing an artificial wall between them.

The advantage is focused topical authority: engines recognized a definitive bidirectional link between the pillar and each spoke, confirming that all the cluster was about one well-defined topic in depth rather than covering a broader spread of loosely related pages.

Link equity flow

Link equity is the authority a page passes to another through a link, and it doesn’t distribute evenly or infinitely — each page splits its passable equity across its outbound links, and each additional hop from the original source dampens how much arrives. The initial work developing PageRank, by Page, Brin, Motwani, and Winograd at the Stanford Digital Library Technologies Project, described setting the damping factor to 0.85, such that almost 85 percent of a page‘s equity is passed on to its outbound links.

The practical implication is that a page with ten outgoing links will pass around a tenth of the available equity through each, while one with a hundred outgoing links will only pass a hundredth through each. That‘s why a fat footer or “About Us” page with dozens of links can surreptitiously cause some of the pages most in need of equity to fail miserably, even when the site appears to be a normal functioning site on the surface.

You can’t manipulate this with nofollow tricks or clever link ordering — Google’s crawlers have long since adapted to those tactics. The reliable lever is deciding deliberately which pages deserve a link from your highest-authority content, and keeping your priority pages shallow in the site’s structure so fewer hops stand between them and the equity your strongest pages have already earned.

Q&A Access Is More Convenient

What is the best internal linking strategy for SEO?

So the ideally balanced strategy is a conscious topical framework hub-and-spoke if your site is that style, silo if you do it another way using ‘contextual’, descriptive links that make clear to visitors and search engines how one page connects to another, instead of unlinked or link-only pages.

How many internal links should a page have?

There‘s no defined maximum, but a reasonable working guideline is roughly anywhere between 2 and 5 contextual internal links for every 1000 words. A higher number is not always better than a lower number if you don‘t have a real use for it.

What is the hub and spoke model in SEO?

It‘s a content architecture where a pillar page (main article) interconnects with a series of closely related narrower cluster pages (supporting subarticles), bringing a focused topical authority to a single, unified topic instead of diluting it across unrelated pages.

What is silo structure in SEO?

Silo structure organizes a site into separate topic groups that link heavily within themselves and rarely cross into unrelated silos, which suits multi-topic sites that need clear separation between distinct keyword clusters.

How does link equity flow through a website?

Link equity passes from a page to the pages it links to, splitting across every outbound link and dampening with each additional hop from the original authority source — which is why pages buried deep in a site’s structure, or pages linked from a page with hundreds of outbound links, tend to receive less of it.
