Internal Linking for SEO: How to Pass Authority to Commercial Pages

Internal links tell search engines what matters. They also help users find the next step. Done right, internal linking boosts rankings for commercial pages — the ones that drive leads.

The Hierarchy

• Pillar pages — Broad topics: “SEO for manufacturers,” “B2B web design.” These attract links and traffic.
• Cluster content — Specific articles, guides, FAQs. They support the pillar.
• Commercial pages — Services, products, contact. These convert.

Link from cluster → pillar → commercial. Authority flows down.

What to Link

• Anchor text — Use descriptive, keyword-rich anchors. “SEO for manufacturers” not “click here.”
• Context — Link when it helps the user. Don’t force links into every paragraph.
• Reciprocal — Commercial pages can link back to supporting content. “Learn more about our approach” → pillar.

Common Mistakes

• Orphan pages — No internal links in. Search engines undervalue them.
• Over-optimization — Same anchor everywhere. Looks manipulative.
• Ignoring commercial pages — All links go to blog. Services and products get no authority.
