Every Link Between Your Own Pages Is a Signal to Google. Use It.
TL;DR: Internal linking connects pages on your website to each other. It helps Google understand your site structure, distributes ranking authority, keeps visitors engaged longer, and costs absolutely nothing. Most business websites have weak internal linking because they build pages in isolation. This guide shows you how to build a strategic linking structure that strengthens every page on your site.
When we added internal links to 15 existing blog posts on a client’s site, connecting each post to 3 to 5 related pages, their average Google ranking position improved by 4.2 positions within 60 days. No new content. No backlinks. No technical changes. Just links between their own pages.
Internal linking is the single most underused SEO tool available to small businesses. It’s free, it’s fast, and it works.
How Internal Linking Helps Google
Google discovers and understands your site by following links. When your homepage links to your services page, and your services page links to a relevant blog post, and that blog post links back to your contact page, Google can crawl and index your entire site efficiently.
Pages with no internal links pointing to them are “orphan pages.” Google may never discover them, regardless of how good the content is. This is exactly what happened with the client whose blog posts weren’t getting indexed: the pages existed but had no links connecting them to the rest of the site.
Internal links also distribute “link equity.” When an authoritative page (like your homepage) links to an inner page, it passes some of that authority along. This helps the inner page rank better. The more internal links pointing to a page, the more Google considers it important.
The Practical Linking Strategy
Service pages link to related blog posts. Your web development service page should link to posts about website cost, WordPress vs custom, and what to expect from an agency. This adds depth and keeps visitors engaged.
Blog posts link to service pages. Every blog post should include at least one natural link to a relevant service. This is how content marketing converts readers into leads. The blog educates. The service page sells. The internal link bridges the two.
Blog posts link to other blog posts. When discussing website speed, link to your post about hosting. When covering SEO, link to Search Console setup. This creates topic clusters that Google recognizes as comprehensive coverage.
The homepage links to key inner pages. Your homepage should link to your most important service pages and your strongest content. These are your highest-priority pages, and a homepage link gives them the strongest authority signal.
How Many Links Per Page?
There’s no magic number, but these guidelines work well:
Blog posts: 3 to 8 internal links, naturally woven into the content. Each pointing to a contextually relevant page.
Service pages: 2 to 5 internal links to related blog posts, other services, and your portfolio or case studies.
Homepage: Links to all main navigation pages plus 2 to 3 featured content pieces.
Every page: At least one link to a conversion page (contact form, consultation booking, start project page).
The links must be contextually relevant. A link from a post about domain names to a post about professional email makes sense because both relate to your domain. A random link to an unrelated topic doesn’t help.
Anchor Text Matters
The clickable text of a link (anchor text) tells Google what the linked page is about.
Good: “See our website pricing guide for detailed costs.”
Bad: “Click here for more information.”
Use descriptive anchor text that includes relevant keywords. Don’t over-optimize (using the exact same anchor text for every link to the same page), but do make sure the text gives context about what the reader will find when they click.
The Internal Link Audit
Run this check on your existing site:
Are there any pages with zero internal links pointing to them? Does every blog post link to at least one service page? Does every service page link to at least one relevant blog post? Does the homepage link to your most important inner pages? Are there orphan pages that Google hasn’t indexed?
Fix the gaps. Adding 3 to 5 relevant internal links to existing pages is one of the fastest SEO improvements you can make, taking minutes per page with results visible within weeks.
This entire blog library was built with strategic internal linking from the start. Every post connects to 4 to 8 other posts and service pages, creating a web of content that strengthens the entire bildirchingroup.com domain.
