Internal linking strategy for small sites: a practical structure

A practical internal linking structure for a small site comes down to three habits. Pick two or three pillar pages. Add three to five contextual links to every new article. Check for orphaned pages on a schedule. None of it requires a crawler tool or a redesign, just a checklist you run every time you publish.

Before you start

An internal link only counts if a search engine can follow it. Google's own crawling documentation is specific about the format: Google can only crawl your link if it's an <a> HTML element with an href attribute. A link built from a JavaScript click handler with no real href attribute may never get discovered, which matters if your site uses client-side routing anywhere in the blog templates.

Anchor text is the other half of the setup. Google's guidance asks you to provide context for the link, and set the expectation for your readers. That rules out "click here" and "read more" in favor of a phrase that still makes sense pulled out of the sentence. The same documentation is explicit that stuffing keywords into anchor text is a spam policy violation, not just a style problem, so vary the wording across the two or three links you send to any one page.

Before writing the first sentence of a new article, take five minutes to list your site's pillar topics: the two or three subjects every related post should eventually link back to. For a small site publishing on SEO and AI visibility, that might be a technical audit page and an answer engine optimization overview. A full technical SEO audit is one example of a pillar page other articles can point back to whenever the topic overlaps.

This inventory step matters more for a small site than a large one. A large publisher can afford to let a crawl tool find every orphan and every over-linked page after the fact. A small site with a few dozen articles doesn't need that overhead. A spreadsheet with one row per published article, noting its pillar and the two or three articles it links to, takes minutes to build and stays accurate as long as you update it at publish time, not after the fact.

As of 2026, Google's own crawling documentation still frames this in plain terms: internal links exist to help both readers and crawlers move through a site with purpose, not to satisfy a checklist. Keep that framing in view. It's easy to treat internal linking as a mechanical SEO task and lose sight of the fact that the same links are also the fastest way for a reader to find the next thing they need.

Step-by-step

Pick two or three pillar pages. A pillar page covers a subject broadly and links, in both directions, to the narrower articles that support it. Google's John Mueller has said the top-down approach or pyramid structure helps the search engine understand the context of individual pages, and the same idea holds at any site size. Readers and crawlers both orient faster when a handful of hub pages sit above a larger set of specific ones.

Add three to five contextual links per article. That range is a reasonable baseline for a typical article, on top of standard navigation, and it holds for a small site the same way it holds for a large one. Place the strongest links inside the body copy: in-content links carry more weight than navigation or breadcrumb links, which in turn carry more weight than footer links. An article like getting cited by AI Overviews and Perplexity is a good candidate for a body link back to a broader pillar whenever the two topics touch.

Update older posts when you publish something new. A pillar page only earns its keep if the articles around it actually point to it, including the ones written before it existed. Every time a new article goes live, spend a few minutes finding two or three older posts that should now link to it, rather than relying on the new post to carry the whole weight of the connection by itself.

Write the anchor text before you place the link. It's faster to drop in "read more here" and move on, but that habit leaves a page full of anchors that tell a reader nothing until they click. Decide what the destination page is actually about, in a few words, and use that phrase as the anchor. Different articles linking to the same destination can use slightly different phrasing too, since that variation gives search engines a broader signal about what the page covers than one repeated phrase would.

Keep a simple record of what links where. This doesn't need a dedicated tool on a small site. A tracked spreadsheet, or even the pillar-page inventory from the first step, answers two questions at a glance: which pages have too few incoming links, and which pillar pages have gone stale because nothing new has linked to them in months.

Common mistakes

Treating every article as its own island. A strict silo, where content only links within its own narrow folder, discourages the cross-topic linking that actually helps readers and search engines see how your site fits together. A looser structure, one pillar with related articles linking sideways as well as up, works better for a site with a handful of overlapping subjects. A page like answer engine optimization sits at the intersection of SEO and AI topics on purpose, and it should collect links from both directions rather than being boxed into one category.

Over-linking a single page. Every outgoing link on a page splits that page's link equity, roughly 1/N across the N links present. A page stuffed with links passes less value to each destination than one with a deliberate handful. More links isn't automatically better. Each one should exist because it helps the reader, not because it hits a quota.

Leaving orphan pages behind. An orphan page has zero internal links pointing to it, which makes it hard for both readers and crawlers to find no matter how good the content is. A supporting page like llms.txt is easy to orphan by accident, since it sits outside the normal flow of blog-to-blog links. Run a periodic check, even a manual one on a small site, and fix the orphaned pages that already get organic traffic first.

Relying only on navigation to carry the structure. A site's main menu and footer are necessary, but they can't do the job of contextual links by themselves. A reader who lands on one article rarely clicks into the navigation to explore further. They're far more likely to follow a link placed in the sentence they're already reading. Treat navigation as a floor, not the whole structure.

Skipping the review after a redesign or a content prune. Removing or renaming pages is normal for a growing site, but every removed or renamed page breaks the internal links pointing to it unless something updates them at the same time. A short pass through recently changed pages after any redesign, checking that their inbound and outbound links still resolve, catches most of the damage before a reader or a crawler does.

Frequently asked questions

How many internal links should one article have?

Three to five contextual links in the body is a reasonable baseline for a typical article, on top of standard navigation. Add links because they help a reader find something relevant, not to hit a number, since each additional link on a page splits that page's link value further.

What is a topic cluster, and does a small site need one?

A topic cluster is a pillar page that covers a subject broadly, linked both ways to a set of narrower supporting articles. A small site benefits from the same idea at a smaller scale: pick two or three pillar topics and make sure every new article links back to the pillar it supports.

What is an orphan page, and how do you find one?

An orphan page is a page with zero internal links pointing to it, which makes it harder for both readers and search engines to discover. A manual review of your own site map, or a site audit tool if you already use one, will surface them. Fix the ones that already get organic traffic first.

Do footer and navigation links count as internal links?

Yes, but they carry less weight than a link placed in the body of an article. Contextual, in-content links are the strongest relevance signal, followed by navigation and breadcrumbs, with footer links carrying the least.

None of this needs a platform. It needs a habit you repeat at every publish: name the pillar, add three to five contextual links, and check for orphans once a quarter. Kallos Labs builds that habit into the SEO and AEO work we do for client sites, because a good structure compounds article by article rather than arriving all at once.
