Internal linking for SEO

This lesson covers

  • What internal links are
  • How to write good anchor text
  • How internal links help search engines find pages

Short answer

Internal links are links from one page on your website to another page on the same site. They help visitors find related content. They also help Google and other search engines discover your pages, understand how they connect, and see which pages matter most. Use clear anchor text that describes the page you link to.

An internal link points to a page on your own site. An external link points to a different website.

Internal links do three jobs:

  1. Help visitors. A reader of “how to start a sari-sari store” may also want “sari-sari store supplier list.”
  2. Help crawling. Search engine bots follow links to discover pages (Lesson 0.2).
  3. Share importance. Pages with many internal links look more important. Some ranking value, often called link equity, passes through links.

A page with no internal links pointing to it is an orphan page. Search engines may never find it.

Anchor text is the clickable text of a link. It tells readers and search engines what to expect on the other page.

Anchor textGood or badWhy

Vary your anchor text a little. Linking every time with the exact same keyword looks forced.

Topic clusters: an easy linking plan

A topic cluster is a group of pages on one topic, linked together.

Topic cluster: pillar page linked to cluster pagesKeywordsSearch intentTitle tagsHeadingsInternal linksBacklinksPillarSEO basics
Cluster pages link to the pillar, and the pillar links back to each one.
  • Pillar page: A main guide, like “SEO for beginners.”
  • Cluster pages: Detailed pages on parts of the topic, like “what are keywords.”

Each cluster page links to the pillar. The pillar links to every cluster page. Cluster pages link to each other when it helps the reader. This course is built exactly this way.

  1. Link new pages from older ones. Every new page should get at least two links from existing pages.
  2. Link from your strongest pages. Pages with traffic or backlinks pass more value.
  3. Link where it helps. Add links inside the text where the reader would want more.
  4. Fix orphan pages. Find pages with no links and connect them.
  5. Keep menus simple. Your main navigation should link to your most important pages.

Anchor text quiz

Each question shows a sentence with a link. The reader picks the best anchor text.

1. “Learn more about ___.” Best:
2. You link to a page about GCash cash-in fees. Best:
3. Which is an orphan page?

Common mistakes

  • Using “click here” everywhere. It wastes a chance to describe the page.
  • Adding too many links in one paragraph. Link only what helps.
  • Linking to broken pages. Check links after you delete or move a page (Lesson 4.3).
  • Forgetting old content. Go back and link old posts to your new ones.
