Internal Linking: The SEO Move Nobody Talks About
External links get all the SEO attention. Other websites linking to yours, how authoritative those sites are, how many you have.
Internal links, the links from one page on your site to another, get ignored by comparison. That is a mistake, because internal linking is completely under your control and it is more fixable, right now, than building external backlinks.
What internal linking actually does
When Page A links to Page B, it passes a signal: this other page is relevant to what we are discussing, and it matters.
From a search engine's perspective, pages that receive more internal links are treated as more important. Pages that receive no internal links are essentially invisible, regardless of how good the content is. Search engines find pages by following links. If a page has no links pointing to it from the rest of your site, it is relying entirely on external discovery, which may never come.
Beyond priority, internal links help search engines understand relationships. When your blog post about emergency plumbing services links to your main plumbing services page, you are communicating: these two things are related and here is the more authoritative one. That relationship is part of how Google maps your site's structure and authority.
And from a reader's perspective, contextual internal links that genuinely help someone go deeper on a topic improve the experience of being on your site. That matters too.
The hub-and-spoke model, done simply
The most effective internal linking structure for a small business site is not complicated. You have pillar pages (the hubs) that cover a broad topic at a high level, and supporting pages (the spokes) that go deep on specific subtopics.
The pillar links out to the supporting pages. The supporting pages link back to the pillar. Related supporting pages link to each other where it genuinely makes sense.
This creates a cluster of content where authority flows through the whole group instead of being isolated in individual pages. Google reads the cluster as a coherent body of work on a topic.
The patterns I see most often in audits
Blog posts that link to nothing. The post exists, it might be good, but it has no links to related posts or service pages. It is a dead end that gives nothing to the rest of the site.
Service pages that do not reference each other. If you offer two services that serve overlapping audiences, those pages should acknowledge the relationship and link to each other.
Homepages that link only to nav pages. Your homepage has real authority. If it links only to your five nav links, those are the only five pages benefiting from that. Content that lives deeper in the site is not receiving any of it.
New content that never links back to existing content. Every new page you publish should connect to at least two or three existing pages where the connection is real and useful.
A fix you can start today
Pick your five most important pages. Use Google Search Console to see how many internal links point to each one. For any that have fewer than five internal links from other pages on your site, find every piece of existing content that naturally relates to that page and add a link with descriptive anchor text.
Not "click here." The actual topic: "our plumbing services page," "more on schema markup," "how we structure the audit."
That work is an afternoon of editing and it has compounding returns as your site grows.
