How to silo linking (step by step)

Opening instruction: Open with a one-line contrarian claim, no preamble.

Most SEO pros treat silo linking like a site architecture chart you draw once and then forget about it. In my 200+ outreach campaigns, I’ve seen the sites that rigidly stick to a static silo map stagnate while the ones that treat it as a living hierarchy constantly outrank them. If you’ve failed at silo linking before, it’s probably because you tried to force every page into a bucket instead of letting the topology evolve with your content and your link profile.

Why most silo strategies fail

The usual suspect is treating siloing as a design problem rather than a link equity problem. I’ve audited sites where the owner drew beautiful topical clusters on a whiteboard, then walked away. The problem? Those clusters existed only in a document. The actual internal links—the ones that move PageRank—were still pointing to the homepage or random corner pages. When you don’t map every outbound and internal link against that map, you end up with a “silo on paper” that looks good in a slide deck but passes zero authority in reality.

Another common breakdown happens when teams try to retrofit a new silo onto an existing mess. I’ve worked with clients who had five years of blog posts, product pages, and service pages with no consistent internal linking pattern. Trying to impose a clean hierarchy on that chaos often results in broken navigation, lost link juice, and a drop in rankings because you’re suddenly changing the link graph Google already trusts. The fix isn’t to rebuild from scratch; it’s to audit what’s already passing equity and work outward from there.

The third failure mode is ignoring click-depth. You can have the best themed cluster in the world, but if a page is four or five clicks from the hub page, Google treats it as a deep, low-priority page. I’ve seen teams celebrate getting a new page into a silo, only to realize three months later it’s getting zero organic traffic because every internal link goes through the main navigation, pushing that page to click depth six. Silo linking only works when you actively monitor and keep that depth at three clicks or fewer from the hub.

Step-by-step: Building a working silo from scratch

Step 1: Inventory your topically relevant pages. Open a spreadsheet and list every page on the site that could belong to a topic cluster. I usually start with the top 200 pages by traffic, then add any money pages that don’t get organic traffic but are critical to conversions. Don’t worry about perfect categorization yet—just get everything in one place so you can see the volume you’re working with.

Step 2: Identify your hub pages. Look at that list and pick the pages that already have the most internal links pointing at them, or the ones that rank on page one for your target keywords. Those become your natural hubs. If you’re launching a new site and don’t have hub pages yet, choose the page that best represents the broadest intent in that topic—usually a pillar page or a comprehensive guide.

Step 3: Map spoke pages to each hub. Go through your spreadsheet and assign every other page to the hub that makes the most thematic sense. Be strict about this: a spoke page should be directly about a subtopic of the hub’s main theme. If it’s a stretch, it probably belongs in a different silo or as its own topic altogether. I’ve seen too many sites where a “SEO tools” page got assigned to a “content marketing” silo just because the writer thought it fit; it diluted both clusters.

Step 4: Insert contextual internal links. Now grab your CMS or a spreadsheet formula and start linking from each hub to its spokes, and from each spoke back up to the hub. The anchor text should match the subtopic, not a generic “click here.” If you’re using OptiLink, you can run a silo report that shows you exactly which pages need a link to reach hub status within three clicks. Without a tool, I manually count clicks from the hub page to every spoke; if any are four or above, I add a direct link from the hub or from a closely related spoke.

Step 5: Audit link flow quarterly. Set a calendar reminder to run this audit every three months. Add new content to the appropriate silo, move spoke pages if their intent shifts, and kill any pages that no longer serve the topic. The sites that keep their silos tight are the ones that treat this as a rhythm, not a one-time project.

Common mistakes that tank link equity

One mistake I see repeatedly is building silos based on keyword match rather than user intent. A page might rank for “best running shoes” and another for “running shoe maintenance,” but if the user intent is different—one is transactional, the other informational—forcing them into the same silo creates a confusing experience and dilutes the signal. I’ve had to untangle clusters where the client insisted on grouping everything under “running shoes” because that was their top keyword, only to watch rankings drop because the internal links were sending mixed signals to Google.

Another frequent error is over-optimizing anchor text within the silo. Some teams go crazy using exact-match keywords on every internal link, thinking it’ll boost the hub’s rank faster. What actually happens is Google flags the pattern as manipulative, and you end up with a manual action or a ranking dip. Keep the anchor text varied and natural; if the spoke page is about “how to lace running shoes,” use that phrase or a close variation, not “running shoes” on every single link.

A third mistake is forgetting about the outbound link profile. I’ve audited sites where the hub page linked out to five authoritative sources in the same niche, and those outbound links were all from the same thematic cluster. That’s not a problem in itself, but if you’re also interlinking those outbound sites back to you in a reciprocal pattern, you’re creating a link loop that Google can devalue. Keep outbound links relevant and sparse, and don’t feel obligated to link out just to “balance” the silo.

Benchmarking your silo against the competition

How do you know if your silo is actually working? Compare your internal link distribution to a site that ranks above you for your target terms. I like to use a backlink crawler set to also show internal links—Ahrefs, Screaming Frog, or even the free version of Sitebulb will show you the internal link graph. Look at the top-ranking page’s hub: how many internal links point to it? What’s the anchor text distribution? If their hub has 40 internal links with varied anchors and yours has 8 all using exact-match keywords, that’s a quick win you can fix without creating new content.

Another benchmark is click-depth. Open the competitor’s site in a new tab, navigate from their main navigation to the hub page, then from the hub to a top-ranking subpage. Count the clicks. If you’re at four or five and they’re at two or three, you have a structural advantage to exploit. I’ve seen sites jump from page three to page one on their target keyword just by adding two direct internal links from the hub to the money page, reducing click-depth from four to two.

You can also benchmark the ratio of hub-to-spoke links. A healthy silo typically has one hub page linking to 5–10 spoke pages, and each spoke linking back to the hub at least once. If your site has one hub linking to 30 spokes, you’re diluting the equity across too many pages. Condense those spokes into sub-silos or give the extra pages their own hub. The math is simple: link equity is a finite resource per page, and spreading it too thin helps nobody.

The overlooked factor: external signals and topical authority

Most SEOs stop the silo conversation at internal links, but I’ll let you in on a secret that took me years to learn: internal linking only does half the work. If you build a perfect silo structure but have zero authority in that topic from the outside, Google will still struggle to rank your hub pages because they lack the thematic weight that comes from external citations. I’ve seen sites with razor-sharp internal architectures rank on page two forever, while a competitor with a messier structure but a handful of quality editorial links from industry publications cracks the top three. The external links act as a thematic validator; when an authoritative site links to your “Ultimate Guide to Running Shoes,” Google takes that as a signal that your entire silo belongs in that niche.

That said, you don’t need to chase links haphazardly. The most effective approach is to look at the external link profile of your top-ranking competitors and mirror the topics they’re getting cited for. If every site linking “running shoes” also links to resources about “sustainable athletic wear,” that’s your cue to make sure that subtopic has its own spoke page with dedicated internal links and, eventually, its own outreach angle. The silo becomes the engine, but the external links provide the fuel. In my campaigns, I always run a quick competitor backlink audit before finalizing a silo map—it tells me which subtopics are hot and which ones I can afford to let slide.

Real-talk conclusion

Silo linking stops being a “strategy” and starts being a habit the moment you stop treating it as a one-off site redesign and start treating it as the way you internally link every piece of content you publish. I’ve watched sites move from organic declines to steady month-over-month growth just by auditing their existing link graph, identifying their natural hubs, and committing to keeping every new page within three clicks of that hub. It’s not glamorous, and it doesn’t make for a great case study slide, but it is the most reliable way to make sure every page on your site has a fighting chance to rank.

If you’re tired of watching your content get indexed but never rank, give the three-click rule a try on your next five posts and see if the traffic doesn’t start creeping up. And if you want a hand mapping out the clusters and tracking the link flow without the spreadsheet hell, OptiLink handles the heavy lifting so you can focus on the content rather than the topology.
