How to Use Internal Links to Build Authority, Improve Rankings, and Guide Customers

Why Internal Links Shape Search and User Flow

Internal linking is more than a structural detail; it is a critical signal for both search engines and human visitors. When planned with intention, internal links guide search engine crawlers, elevate high-value pages, and extend user sessions by offering natural next steps. But when overlooked or misused, they can bury your best content, confuse your hierarchy, and create future technical debt.

Visitors typically arrive with one of two intentions: a quick answer or a path to deeper exploration. Your job as an SEO or strategic web leader is to accommodate both. That means your pages need a clear conversion opportunity or a thoughtfully placed internal link that moves the visitor toward one.

Think of Internal Links Like Backlinks from Yourself

Internal links carry weight. Not as much as backlinks, of course, but enough that you should think of them similarly. Just as backlinks pass credibility between domains, internal links pass authority within your own site. When you place a link from a high-authority blog post to a low-performing but important product page, you are casting a vote of importance. Do it enough, and search engines notice.

This is not just theory. I have worked on enterprise sites where internal links alone, no new content, moved critical pages from page 3 to page 1 in a matter of weeks. We simply restructured the flow, tightened the anchors, and elevated the right content. Authority, once siloed, was now circulating.

At scale, this becomes site architecture strategy. But even on small or mid-sized websites, every internal link you place is a chance to define your own relevance map. Search engines crawl your site based on what you link to. Make sure you are reinforcing the content that matters.

Customer Journeys Are Shaped by Internal Links

Internal linking is not just about SEO: it is also one of your best tools for shaping user journeys. If you assume a visitor will make their decision on the landing page, you are gambling. Internal links let you hedge that bet by creating logical paths forward to deeper resources, comparison content, trust-building assets, or supporting CTAs.

One of the best places to apply this logic is at the bottom of the page. If someone scrolls through your entire article but does not convert, that is not a dead end, it could very well be an opportunity. A well-placed internal link to a related guide, case study, or buying page can extend the session and keep intent alive.

FAQs are another underutilized space. When a user expands a question, it often signals lingering interest or hesitation. Internal links in these sections can offer relief: “Not sure which plan is right for you? See our detailed plan breakdown here.”

How Structured Systems Drive Strategic Internal Linking

While contextual links within content are vital, the real leverage in internal linking comes from structured systems sitewide or section-specific elements that deliver consistent link equity and reinforce your content strategy. These include things like hub pages, content categories, sidebars, and navigational components that automate and distribute internal links at scale.

One standout example is Atlassian’s Agile Coach– my digital vacation home. I love this site because it is well written, well organized, and getting tons of traffic if SEMRush is to be trusted. It is a perfect model of what internal linking should look like when content is organized around deep subject matter authority. On every article, a persistent sidebar acts as a table of contents. Not only does it give users a clear mental model of the content universe, they can jump directly to what they need; but it also creates a robust mesh of internal links. To a search engine, this says: “These pages are connected. They matter. Crawl them together.”

Hub Pages, Category Pages, and Strategic Clustering

Internal linking becomes especially powerful when paired with a hub-and-spoke content model. A hub (or pillar) page serves as the central authority on a topic, linking out to detailed subpages, which in turn link back to the hub. This flow supports crawl accessibility, topic relevance, and user exploration. It also gives you a home base for interlinking when new content is added to your site.

Category pages often get overlooked because they are not glamorous. But even if few users directly visit them, they play a major role for bots and for accessibility. If designed well (and not just as a bland list of links), they can passively improve your crawl depth and distribute relevance to older content that might otherwise decay.

One of my consistent internal linking principles: not everything needs to rank, but everything should connect. That connection does not always need to be editorial. Automated modules, “related article” blocks, and semantic groupings in navigation all count so long as they reinforce hierarchy and provide crawl paths.

Secondary Navigation and Political Workarounds

Primary navigation often becomes political real estate. Stakeholders fight for visibility, and over time, your top menu turns into a junk drawer of conflicting priorities. This is where secondary navs shine.

Secondary navigation bars, placed at the section or page level, give you an opportunity to guide users and bots without cluttering your global menu. These menus can live on blog templates, resource pages, or even product areas, and they allow you to drive internal link flow where it matters most.

In multiple organizations I have worked with, we introduced secondary navs not as design elements, but as internal link distributors. We prioritized key commercial pages or cornerstone content that was otherwise buried and watched traffic and indexation improve. Even when user clicks were low, crawl behavior changed. That is the magic of a good internal linking system: it works behind the scenes.

Sidebar Navigation and Persistent In-Content Links

Sidebars can act like contextual nav systems within content-heavy environments. Whether you are building a documentation hub, a blog guide, or a vertical learning series, persistent sidebars help surface long-tail content without requiring you to stuff internal links unnaturally into every paragraph.

One warning, though: too many sidebar links can dilute equity. Keep your sidebar curated. If you try to link to every piece of content you have written, none of it will carry weight. Choose the right pages based on funnel depth, recency, or authority, and audit these lists periodically. Ironically, this is where that Atlassian sidebar is a real head scratcher – it defies conventional wisdom… I still say limit your links and organize them well – 155 links to 135 pages is not a good look. You want to see a clean hierarchy that reflects your page importance in the number of internal links/ referring pages a page has.

Anchor Text Strategy: Send Clear Signals to Search Engines

Anchor text is more than styling, it is a signal. Search engines use anchor text to help understand the context of the page being linked to. That means vague phrases like “click here” or “learn more” do little to support your SEO efforts. Instead, your anchor text should describe the target page with relevance and specificity.

For example, instead of linking with: “Learn more about our features”, Try: “Compare our pricing and plan features”

This reinforces the topic of the target page and strengthens its keyword alignment. That said, avoid over-optimization. Repeating the same anchor text across dozens of pages can look manipulative. Use natural variations while staying relevant. If you are targeting “customer journey analytics,” you can rotate with:

• “Explore customer journey tools”
• “Track behavior across the customer lifecycle”
• “Customer journey analytics platforms”

You want your anchor text to clarify the intent behind the link.

Internal Linking Mistakes That Create Long-Term Problems

Internal links are powerful, but they can also backfire if misused. Some common pitfalls to avoid:

• Orphan pages: Pages that receive no internal links are difficult to crawl and almost impossible to rank. Always ensure new content is linked from at least one existing indexed page.
• Overstuffed links: Pages with dozens of internal links (especially footers and sidebars) dilute link equity. Focus on relevance, not volume.
• Broken internal links: These damage user experience and crawl flow. Use tools like Screaming Frog, Sitebulb, or Ahrefs to regularly audit and fix them.
• Redundant redirect chains: Internally linking to a redirected page slows crawlers and weakens authority. Always link to the final destination.

The goal of internal linking should be to maintain a healthy internal system that supports both humans and bots without bloating crawl budgets or confusing page relationships.

When Internal Linking Should vs Should Not Be a Priority

Internal linking becomes more impactful as your site grows. For small websites with fewer than 20–30 pages, most internal links are likely already visible via the nav or footer. In these cases, your time is better spent creating new, useful content. But as your site expands, internal linking quickly becomes a force multiplier.

That said, I often see teams defer internal linking until it becomes a cleanup project, at which point, it is technically expensive and messy. My recommendation is simple: build internal linking into your content publishing checklist. Every new article should link to at least two existing pieces and be linked to from at least one other relevant page or hub. Update your internal links in revisions as well.

This habit prevents fragmentation and future-proof your architecture. It also makes performance measurement cleaner, as you can isolate which pages are gaining equity from internal links and which are being left behind.

Internal Links Are Your Site’s Vascular System

If backlinks are your external endorsements, internal links are your circulation system. They control how trust, authority, and traffic flow through your site. Ignore them, and your site becomes fragmented. Use them well, and you create momentum, hierarchy, and scale.

The best sites keep site visitors moving, and internal linking is what makes that possible. Happy linking!
