What is internal linking and how does it help my local SEO?
An internal link is a link from one page on your website to another page on your website. Navigation links, footer links, and links you include within the body of blog posts or service pages are all internal links. They're one of the most overlooked, easiest-to-improve aspects of local business websites — and getting them right helps both your rankings and how easily customers can find what they're looking for.
How internal links help SEO
Internal links do two important things for search engine optimization:
- They distribute "authority" (link equity) around your site. When external websites link to your homepage, that authority can flow through internal links to other pages. A well-linked service page benefits from the authority your homepage receives.
- They help Google discover and understand your pages. If a page has no internal links pointing to it, Google may not find it — or may treat it as low-importance. Pages linked from your homepage are treated as more important than pages buried three clicks deep.
Which pages to prioritize for internal links
Your most important pages for local SEO are your service pages and location pages. These are the pages you want to rank — so they should receive the most internal links from other pages on your site.
- Link to your main service pages from the homepage
- Link to location/service area pages from your homepage, service pages, and a dedicated "Areas We Serve" page
- Link to related service pages from each service page ("Interested in our drain cleaning service? Check out our full plumbing services...")
- Link from blog posts to the most relevant service page ("If you're dealing with this issue, our water heater repair page has more details")
The service hub architecture
A strong internal linking structure for a local business typically looks like a hub-and-spoke model:
- Hub pages: Your homepage and main category pages ("Plumbing Services," "HVAC Services") are linked from navigation and link to all sub-pages below them
- Spoke pages: Individual service pages ("Water Heater Repair," "Drain Cleaning") and location pages link back to the hub and cross-link to related spokes
This structure ensures every important page is reachable within 2–3 clicks from the homepage and creates a logical hierarchy Google can understand.
Common internal linking mistakes
- Orphan pages — Pages with zero internal links pointing to them. Google may never index these.
- Generic anchor text — "Click here," "Read more," "Learn more" tell Google nothing about the destination
- Linking to the same page with different anchor texts constantly — Pick 2–3 primary anchor texts per destination page and use those consistently
- Too many links on one page — A page with 150 internal links dilutes the authority passed to each destination. Focus on 5–15 contextually relevant links per page.
A quick internal link audit
Open Google Search Console → Sitemaps and check that all your key pages are indexed. Then use the "Links" report to see how many internal links each page receives. Any important page with zero internal links is an immediate fix.
Key Takeaways
- Internal links distribute authority between your pages and help Google discover and prioritize them
- Your most important pages (service pages, location pages) should receive the most internal links
- Always use descriptive anchor text — "water heater installation in Austin" is far better than "click here"
- A hub-and-spoke structure (homepage → category pages → individual service/location pages) creates a clear, SEO-friendly hierarchy
- Check for orphan pages (pages with no internal links) in Search Console — these are a quick fix with immediate impact
