This skill should be used when the user asks to "build an internal linking strategy", "improve internal links", "internal linking for SEO", "link between pages on my site", "internal link structure", "connect pages for SEO", "internal linking audit", "fix internal linking", or any variation of building, optimizing, or auditing internal linking strategy for B2B SaaS websites.
Internal Linking for SaaS
Internal linking is how you connect pages on your own site. Every internal link passes authority, signals topical relevance, and helps Google discover new pages. A well-linked site makes every page stronger. A poorly linked site isolates pages and wastes the authority you've built.
For SaaS sites with 50+ pages, internal linking is often the single highest-ROI SEO action — it requires zero external effort, zero budget, and can be implemented in a day.
Internal Linking Rules
Rule 1: Every page links to 3-5 related pages
Every page on your site should contain 3-5 contextual links to related pages. Not in a sidebar. Not in a footer. In the body content, where they're relevant to the reader.
| Source page type | Link to |
|---|---|
| Blog post about lead scoring | → Glossary definition of lead scoring, → How-to guide for setting up scoring, → Comparison of scoring tools, → Product feature page |
| Comparison page (X vs Y) | → Your pricing page, → Related comparison pages, → Product feature page, → Case study |
| Glossary term | → Comprehensive guide on the topic, → Related glossary terms, → Blog posts that discuss the concept |
| Case study | → Product page, → Use case page for the same industry, → Related case study |
Rule 2: Use descriptive anchor text
| Bad anchor text | Good anchor text |
|---|---|
| "Click here" | "See our lead scoring comparison" |
| "Learn more" | "Read the complete guide to pipeline forecasting" |
| "This article" | "Our analysis of cold email reply rates" |
| Raw URL | "HubSpot vs Salesforce comparison" |
Rule: Anchor text should describe the destination page's topic. It gives Google a relevance signal about what the linked page is about.
Rule 3: Link from high-authority pages to important pages
Your highest-traffic and most-linked pages have the most authority to pass. Use them strategically.
| High-authority page | Link it to |
|---|---|
| Homepage | Top comparison pages, pricing, product pages |
| Top blog post (by traffic) | New content you want to rank, key product pages |
| Most-linked page (by backlinks) | Priority pages that need ranking boost |
Rule 4: New pages get links immediately
When you publish a new page, add links to it from 3-5 existing pages on day 1. This ensures Google discovers and crawls the new page quickly.
Process on every publish day:
- Identify 3-5 existing pages related to the new page's topic
- Add a contextual link from each existing page to the new page
- Add links from the new page back to 3-5 related existing pages
Rule 5: Hub pages link to all spokes
If you use topic clusters, every hub page must link to every spoke page in the cluster. Spoke pages link back to the hub and to 1-2 adjacent spokes.
Internal Linking Audit
How to audit
- Crawl your site with Screaming Frog or Ahrefs Site Audit
- Check these metrics:
| Metric | Target | How to fix |
|---|---|---|
| Pages with 0 internal links pointing to them (orphans) | Zero | Add links from related pages |
| Pages with only 1 internal link | Minimum 3 links per page | Add links from additional related pages |
| Average internal links per page | 5+ | Add contextual links to underlinked pages |
| Anchor text distribution | Descriptive, varied | Replace generic "click here" with descriptive text |
| Crawl depth (clicks from homepage) | ≤ 3 for priority pages | Add links from navigation or hub pages |
| Broken internal links | Zero | Fix or update broken links |
Priority fixes
| Fix | Impact | Effort |
|---|---|---|
| Link to orphan pages from 3+ related pages | Very high | 5 min per orphan |
| Add links from top 10 pages (by traffic) to priority new content | High | 15 min total |
| Replace "click here" anchor text with descriptive text | Medium | 2 min per link |
| Add breadcrumbs to all pages | Medium | 1-time dev implementation |
| Create hub pages for topics with 5+ related pages | High | 2-4 hours per hub |
Automated Internal Linking
For sites with 100+ pages, manual internal linking doesn't scale. Implement automated linking.
| Method | How it works | Best for |
|---|---|---|
| Related posts plugin/component | Automatically shows 3-5 related pages at the end of each page | Blog posts, guides |
| Glossary auto-linker | Automatically links glossary terms when they appear in content | Sites with glossary pages |
| Topic tag pages | Tag-based hub pages that auto-aggregate related content | Large content libraries |
| Contextual link suggestions | Tool suggests internal links while writing (Yoast, LinkWhisper) | Writing workflow integration |
| Programmatic cross-links | Code-generated links between related pSEO pages | pSEO sites with 50+ pages |
Pre-Audit Checklist
- [ ] Site crawled with Screaming Frog or equivalent
- [ ] Orphan pages identified (pages with zero incoming internal links)
- [ ] Underlinked pages identified (pages with < 3 incoming links)
- [ ] Priority pages identified for link boosts
- [ ] Anchor text audit completed (generic vs descriptive)
- [ ] Breadcrumb implementation checked
- [ ] Hub pages exist for major topic clusters
- [ ] New page linking process documented (3-5 links on publish day)
- [ ] Automated linking evaluated for scale needs
- [ ] Broken internal links fixed
Anti-Pattern Check
- Orphan pages exist on the site → Pages with zero internal links can't be crawled or ranked. Find orphans with Screaming Frog and add 3+ links from related pages immediately
- All internal links are in the sidebar or footer → Sidebar and footer links carry less weight than contextual body links. Add links within the body content where they're relevant to the reader
- "Click here" as anchor text → Generic anchor text wastes a relevance signal. Use descriptive text that tells Google what the linked page is about
- New pages published with zero internal links → Google may not discover the page for weeks. Add 3-5 links from existing pages on publish day
- No hub pages for major topics → Without hub pages, related content is disconnected. Build a comprehensive hub page for every topic with 5+ related pages
- Internal linking is a one-time project → Internal links should be updated every time new content is published. Build linking into the publishing workflow, not as a quarterly cleanup
