Internal Linking Strategy: How to Pass Authority and Build Topical Authority
Written by Gabriel Bertolo
July 6, 2026
Internal linking is the on-page lever with the widest gap between how much it matters and how well it gets used.
You control it completely. There’s no outreach, no waiting on another site to decide you’re worth linking to, no budget required. Every link is yours to place. And yet most of the sites I audit treat internal linking like an afterthought, scattering a few “click here” links around and calling it a day. Meanwhile, their most important pages sit cut off from the authority that internal links are designed to pass.
Here’s the reframe that changes how you see all of this. Every internal link is a relationship declaration. When you link from one page to another, you’re telling search engines these two pages are connected, that the destination matters, and, through your anchor text, what it’s about. That’s not navigation. That’s you actively shaping how search engines understand your site.
And the scale of the waste is real.

A full quarter of all content is sitting there with no authority flowing to it, nearly invisible to the search engines it’s trying to reach.
This guide is part of our larger complete guide to on-page SEO, and it goes deep on the one lever you have total control over.
Internal links do three jobs, and understanding all three is what separates strategic linking from random linking.
First, they pass authority. When a page earns authority, whether from backlinks, age, or its position in your site, internal links distribute that authority to the pages they point to. Think of it as the way value moves around your site. A strong page that links to a weaker one shares some of its strength.
Second, they guide crawlers. Search engine bots discover your content by following links. When you link to a page, you’re creating a path for crawlers to find and recrawl it. Pages with lots of internal links pointing to them get crawled more often, which means updates get noticed faster.
Third, they build topical structure. The pattern of links across your site shows search engines how your content relates. When your pages on a single topic link to each other in a logical structure, you’re demonstrating that you cover that topic with genuine depth, not just a scattered article here and there.
Most people only think about the first job, if they think about any of them. But the real power comes from doing all three on purpose.
The anchor text, the clickable words in a link, is how you label the relationship you’re declaring. And it’s where most sites quietly squander their best opportunity.
“Click here” tells search engines nothing. “Read more” tells them nothing. “This article” tells them nothing. Every time you use a generic anchor, you’re wasting an opportunity to reinforce what the destination page is about.
Compare that to descriptive anchor text like “internal linking strategy” or “schema markup for local businesses.” Those anchors tell search engines exactly what they’ll find on the other end of the link. They label the relationship clearly, and that clarity helps the destination page rank for the terms in the anchor.
The rule is to use descriptive, natural anchor text that accurately describes the page you’re linking to. But there’s a balance to strike. If every link to a page uses the identical exact-match keyword, that starts to look manipulative. Natural internal linking uses varied anchors. Sometimes the exact keyword, sometimes a variation, sometimes the surrounding sentence carries the context. Write the way you’d write for a reader, and the anchors tend to come out natural.
Link equity, sometimes called link juice, is the authority that passes through a link. Understanding how it flows is what lets you direct it on purpose.
Picture your site as a network of pipes. Your homepage is usually the biggest reservoir of authority, because it tends to attract the most backlinks. Your popular blog posts and key service pages are smaller reservoirs. Internal links are the pipes that move authority between them.
When a high-authority page links to another page on your site, it sends some of its authority along that pipe. So the pages you link to most often, from your strongest pages, accumulate the most authority. This is the mechanism you’re controlling when you build an internal linking strategy. You’re deciding where the authority flows.
The practical takeaway is simple. Your most important pages, the ones that drive revenue, should receive the most internal links from your strongest, most relevant pages. If your money pages are only linked from a single buried blog post, they’re starved. Point more authority at them.
One more thing worth knowing. The more links on a page, the less authority each individual link passes. A page with 5 outbound links sends more authority through each one than a page with 150. This doesn’t mean you should be stingy with links, but it does mean every link should earn its place.
Here’s how this plays out in practice. I worked with a direct-to-consumer jewelry brand that had a blog article quietly ranking near the bottom of page two for one of their most valuable search terms. The page had decent authority but was poorly optimized and, critically, had no internal links pointing to it. It was a strong page nobody was feeding. I rewrote it to sharpen the keywords and entities, then pointed internal links at it from ten topically relevant pages, and linked out from it to the homepage and the main category page. Within a month it moved from the bottom of page two to the top of page one, and its traffic rose 840%. But here’s the part that shows authority flowing both directions: the category page that article linked to saw its own traffic climb 143%. The links didn’t just lift the target page. They redistributed authority across the whole cluster.
Click depth is how many clicks it takes to reach a page from your homepage. And it functions as an importance signal to search engines.
The general rule is that your important pages should sit within three clicks of the homepage. A page that’s one click deep is signaling high priority. A page buried six or seven clicks down is signaling that even you don’t think it matters much. Search engines crawl shallow pages more often and treat them as more important.
This is where a lot of sites quietly sabotage themselves. They publish a genuinely valuable page, then bury it so deep in the site structure that it takes five clicks and a treasure map to find. The content might be excellent, but the depth signals otherwise, and the rankings reflect it.
When I audit a site, one of the first things I check is whether the revenue pages are reachable in a few clicks. I ran into this with a Western Massachusetts service business whose main money page, the one that actually generated calls, sat five clicks deep behind a tangle of dropdown menus. The page was solid. It just may as well have been hidden in the basement. Pulling it up to two clicks from the homepage and pointing a handful of internal links at it from stronger pages was one of the highest-impact changes in the whole engagement, and it cost nothing but a bit of restructuring.
An orphan page is a page with no internal links pointing to it. It exists, but it’s disconnected from the rest of your site.
Orphan pages are a problem for every reason internal links matter. Crawlers struggle to find them, because there’s no link path leading there. No authority flows to them, because authority travels through links. And they sit outside your topical structure, disconnected from the content they should relate to. Even if an orphan page is in your XML sitemap, the lack of internal links tells search engines it isn’t really part of your connected body of work.
Orphans usually happen by accident. An old blog post that nobody linked to. A service page that got dropped from the navigation during a redesign. A landing page built for an ad campaign and never integrated into the site. They pile up over time without anyone noticing. I’ve opened up crawls for clients and found dozens of orphaned pages they didn’t even remember publishing, all of them sitting there contributing nothing.
The impact of fixing this can be dramatic. I audited a local service business whose site had almost no internal links connecting its pages, with plenty of content sitting effectively orphaned. Going through and strategically interlinking everything, with no other changes at all, produced a 118% increase in organic traffic. That was the single variable. No new content, no new backlinks, no technical overhaul. Just connecting pages that should have been connected all along. It’s the clearest proof I have that internal linking is a lever in its own right, not just a finishing touch.
The most effective internal linking structure is the hub-and-spoke model, also called topic clusters.
It works like this. One comprehensive pillar page, the hub, covers a broad topic. A set of focused spoke pages each go deep on a specific subtopic. The hub links out to every spoke, and every spoke links back to the hub. Spokes also link to each other where the topics genuinely intersect.
This structure does something powerful for how search engines understand your site. It explicitly shows them that you don’t just have one article on a topic. You have an interconnected body of knowledge that covers the subject from every angle. That demonstrated depth is what builds topical authority.
Here’s a live example. The article you’re reading right now is a spoke. It’s part of a cluster built around a pillar page on on-page SEO, alongside sibling spokes on search intent, title tags, content clusters, and image optimization. The pillar links down to each of us. We link back up to it. And where it makes sense, we link to each other. That’s the hub-and-spoke model in action, and it’s a big part of how we build topical authority through content clusters.
A few principles pull all of this together into a workable strategy.
Favor contextual links over navigational ones. A link embedded in the body of your content, surrounded by relevant text, carries more weight than a link in your footer or sidebar. Contextual links signal a genuine editorial relationship between the two pages. Navigation links are useful for users, but they’re sitewide and carry less unique signal.
Keep your link density reasonable. A common guideline is a few contextual links per 1,000 words, with total links on a page staying well under 150. The exact number matters less than the principle: every link should serve the reader and the relationship, not pad a count.
Link to your priority pages from your strongest pages. Be deliberate about directing authority where you want it. Your best-performing content should be passing some of its strength to the pages you most need to rank.
Link related content together. When two pages genuinely relate, connect them. This builds the topical structure that signals expertise and keeps readers moving through your site.
Audit regularly. Internal linking is never finished. As you publish new content, you create new opportunities to link and new pages that need links pointing to them.
One thing worth saying here is that the right approach shifts with the size of the site, and in our market, that difference is stark. A rural Hampshire County contractor with twelve pages has the opposite problem from a multi-location Springfield or Boston operation running several hundred. The small site doesn’t have enough pages to build real clusters, so every single link has to earn its place and point somewhere that matters. The large site has the reverse issue, where orphan pages multiply, crawl budget gets wasted on low-value URLs, and the work becomes about pruning and directing rather than adding. Same principles, very different execution depending on how much site you’re working with.
These are the mistakes I see over and over when auditing sites.
Generic anchor text. “Click here” and “read more” everywhere, wasting every relationship-building opportunity.
Orphan pages. Valuable content sitting with no internal links, invisible to crawlers, and cut off from any authority.
Over-linking. Cramming so many links onto a page that none of them carry meaningful weight, and the reading experience suffers.
Linking everything to the homepage. The homepage usually doesn’t need more links. Your deeper pages do.
Broken internal links. Links pointing to pages that no longer exist, creating dead ends, wasting crawl budget, and signaling neglect.
No contextual links in content. Relying entirely on navigation menus and never linking within the body of the content, which is where the most valuable links live.
You don’t need expensive tools to understand your internal linking, though they help.
Start with a crawl. Screaming Frog or Sitebulb will map your entire site and show you the internal links pointing to each page, your orphan pages, your click depth, and your broken links. This gives you the full picture in one pass.
Use Ahrefs or Semrush for a health check. Their site audit tools flag internal linking issues, orphan pages, and pages with too few or too many links.
Check Google Search Console. The Links report shows you which of your pages have the most internal links, which can reveal whether your priority pages are getting the attention they need.
What you’re looking for is the gap between your most important pages and the internal links they actually receive. When you find a revenue page that’s buried deep and barely linked, you’ve found an opportunity.

How many internal links should I have per page?
There’s no hard rule, but a few contextual links per 1,000 words is a reasonable guideline, with total links on a page staying under roughly 150. Focus on relevance over quantity. Every link should genuinely help the reader or reinforce a real relationship between pages.
What is anchor text?
Anchor text is the clickable words in a link. It labels the relationship between the two pages and tells search engines what the destination page is about. Descriptive anchor text like “internal linking strategy” carries far more value than generic anchors like “click here.”
Do internal links help SEO?
Yes, significantly. Internal links pass authority between your pages, help search engines discover and crawl your content, and build the topical structure that demonstrates expertise. They’re one of the few ranking levers you control completely.
What are orphan pages?
Orphan pages are pages with no internal links pointing to them. They’re hard for search engines to discover, they receive no authority from the rest of your site, and they sit outside your topical structure. Connecting them back into your site is usually a quick, high-impact fix.
How do I build internal links?
Link related pages together using descriptive anchor text, point links from your strongest pages to your priority pages, keep important pages within three clicks of the homepage, and use the hub-and-spoke model to build topic clusters. Audit regularly to catch orphan pages and broken links.
Internal linking is the lever you control completely, and most sites waste it. If your important pages are buried, orphaned, or starved of authority, fixing that is often one of the fastest wins in SEO.
