Backlinks require other people to cooperate. Internal links require nothing but a decision, and they do three jobs at once: they distribute authority between your pages, they show search engines how your topics relate, and they help crawlers find content that would otherwise sit undiscovered.
They're also the thing most WordPress sites handle worst, because linking tends to happen ad hoc — a link here when it occurs to you, nothing for the next thirty posts.
The hub-and-spoke structure
Pick a topic you want to be known for. Write one comprehensive hub page covering it broadly. Then write spoke pages that each go deep on one sub-topic the hub only touches on.
Every spoke links up to the hub. The hub links down to every spoke. Spokes link sideways to each other where genuinely relevant.
This does something specific: it concentrates authority on the hub, which is the page competing for your most valuable and competitive term, while giving each spoke a clear, narrow focus that's far easier to rank for individually. It also makes your topical coverage legible — a search engine crawling that cluster can see you've covered the subject properly rather than published one thin post about it.
A worked example for a WordPress SEO site: the hub is a complete WordPress SEO guide. Spokes are indexing speed, Core Web Vitals, schema markup, meta descriptions, and internal linking. Each spoke stands alone and answers one question thoroughly; together they demonstrate depth no single article could.
Anchor text: descriptive, varied, honest
The clickable text tells search engines what the destination is about. "Click here" tells them nothing.
Write anchors that describe the destination naturally, and vary them — five different pages all linking with the identical exact-match phrase looks engineered, because it is. Natural linking produces natural variation.
The honesty part matters for readers more than robots: an anchor should accurately predict what's on the other side. Nothing erodes trust faster than a link that promises one thing and delivers a sales page.
Mistakes that quietly waste the effort
Orphan pages. A page with no internal links pointing at it is nearly invisible — search engines find it through the sitemap at best, and it receives no authority from anywhere. Audit for these periodically; sites accumulate them without noticing.
Linking only from new to old. Most people add links to older posts when publishing something new, and never revisit. That means your oldest, often strongest, pages never point at your newest work. Go back and add links from established pages to new ones — that's the direction authority actually flows.
Too many links on one page. There's no magic number, but a page with two hundred links dilutes each one and reads like a directory. Link where it genuinely helps a reader.
Navigation instead of contextual links. A link inside a paragraph, surrounded by relevant text, carries more weight than the same link in a footer that appears on every page. Sitewide navigation links are largely discounted precisely because they're sitewide.
Ignoring the depth problem. Anything more than three clicks from your homepage is treated as less important, and often crawled less often. If a page matters, shorten the path.
Doing it in WordPress without it becoming a chore
The habit that works: when you publish a post, immediately add two or three links to it from existing relevant pages. It takes five minutes at the moment you have the most context, and it prevents the orphan problem entirely.
WordPress makes finding targets easy — start typing in the link dialogue and it searches your existing content. For a quarterly audit, filter Search Console by page to find URLs with impressions but few clicks, then check whether anything actually links to them internally.
Why this is worth the discipline
Internal linking is the rare SEO lever with no gatekeeper. You don't need outreach, budget, or anyone's permission — just a structure and the habit of maintaining it. On most sites it's the highest-leverage unglamorous work available, and it compounds: every new post makes the cluster around it slightly stronger.
