External links are like votes of confidence from the rest of the web. Internal links, the ones pointing from one page on your site to another, work more like a nervous system. They don’t just help people click around your site. They also tell search engines which of your pages matter most, how your content relates to itself, and how trust moves through your site.
Most people spend their energy trying to get links from other websites. That’s worth doing, but the smartest place to start is with the links you already control.
How Do Internal Links Actually Help SEO?
Picture your homepage as a city centre. It’s usually where most of your outside trust lands first, since other sites and social shares tend to point there. Internal links are the roads leading out from that centre to smaller towns, your deeper blog posts and product pages, carrying some of that trust along with them.
Search engines also rely on links to discover pages in the first place. They crawl the web by following it. If a page has no internal links pointing to it at all, it becomes what’s known as an “orphan page.”
It’s easy to assume a sitemap fixes this, but a sitemap mostly helps a page get found. It doesn’t carry the same weight as being linked to from real content elsewhere on your site. An orphan page can still read as low-priority or abandoned even while sitting in your sitemap.
What’s the Best Way to Structure Internal Links?
Two structures come up again and again, and the useful thing to know upfront is that they’re not rivals. Most well-built sites use both at once.
The pyramid is the shape almost every site already has, even without trying. Homepage, then category pages, then sub-categories, then individual posts or products. Trust flows down through that structure, and context flows back up.
Hub-and-spoke (sometimes called a content silo) sits inside that pyramid, usually at the category or sub-category level. You write one solid, broad guide on a topic (the hub), then several narrower articles on specific parts of that topic (the spokes). Every spoke links back to the hub, and the hub links out to each spoke. Done well, it tells search engines this whole cluster of pages knows what it’s talking about.
Think of the pyramid as your site’s skeleton and hub-and-spoke as the muscle built onto specific parts of it. You’re not choosing one over the other. Most sites that rank well are quietly running both at the same time.
Why Does Anchor Text Matter?
One of the most common mistakes is using generic text for links.
The weak version: “To read our guide on nofollow links, click here.”
The better version: “For a deeper dive, check out our complete guide to understanding nofollow links.”
Anchor text, the clickable words themselves, gives search engines a clue about what the linked page is about. Google’s own link guidelines confirm this directly: anchor text should be descriptive and relevant, and generic text like “click here” should be avoided. It should also read naturally. Stuffing it full of exact keywords tends to look spammy rather than helpful.
How Many Internal Links Is Too Many?
A few common pieces of advice are worth a second look here, since they tend to oversimplify what’s actually going on:
Depth. You’ll often hear that every page should be reachable within three clicks of the homepage, or it won’t rank well. There’s no confirmed rule that exact, and large sites regularly have pages buried deeper than that without any issue, as long as the internal linking and sitemap around them are solid. The real principle is simpler: don’t bury pages under layers of navigation for no reason. A user or a search engine should be able to find your important pages without a scavenger hunt.
Link count. Another common claim is that packing 200 links onto one page “dilutes” the value of each one. In the original version of PageRank, that was actually true. A page’s authority was mathematically split across its outgoing links, so more links genuinely meant less weight passed through each one.
Modern search ranking is far more nuanced than that original formula, and Google’s own guidance reflects it: there’s no magic ideal number of links a page should have, but if it feels like too many, it probably is. The practical issue today isn’t a strict math penalty. It’s decision fatigue for readers and cluttered context for search engines trying to figure out which links on the page actually matter. Be selective because it helps your reader take the next useful step, not because you’re rationing a fixed pool of trust.
Broken links. Internal links pointing to deleted or moved pages matter mostly because they frustrate visitors and send trust to nowhere useful. They can have a small effect on crawling too, but that’s a secondary concern, not the main reason to fix them.
Keeping It Going
Internal linking isn’t something you set up once and leave alone. It’s an ongoing habit.
Every time you publish something new, ask two questions: which existing pages should this new post link back to, and which older posts should be updated to link to this new one? Keeping those pathways open is what keeps your site structure working for you instead of against you.
