How to Use Internal Links to Improve SEO

Introduction

When most people think of link building, they think of acquiring backlinks from other websites (external links). However, one of the most powerful and entirely controllable SEO strategies is internal linking—connecting the pages within your own website.

Why Internal Links Matter

• Crawlability: Search engine bots follow links to discover new pages. If a page has no links pointing to it (an "orphan page"), Google may never find it.
• Site Architecture: Internal links help establish a hierarchy, showing search engines which pages are the most important (cornerstone content).
• Distributing Page Authority: When a high-ranking page on your site receives backlinks from external sites, it gains authority. Internal links pass some of this authority (link equity) to other pages on your site.
• User Experience: Relevant internal links keep visitors on your website longer, reducing bounce rates and increasing engagement.

Best Practices for Internal Linking

1. Use Descriptive Anchor Text

Anchor text is the clickable text in a hyperlink. Avoid generic phrases like "click here" or "read more." Instead, use descriptive text that indicates what the linked page is about. E.g., instead of "Click here for our SEO guide," use "Read our comprehensive SEO guide."

2. Link Deep

Avoid linking primarily to your homepage or contact page. Focus on "deep linking" to specific blog posts, product pages, or detailed guides that provide additional value relevant to the current context.

3. Update Old Content with New Links

When you publish a new article, it starts with zero internal links. Make it a habit to revisit older, high-performing articles and add relevant links pointing to your newly published content.

4. Use 'Topic Clusters'

A highly effective SEO strategy is creating a comprehensive "Pillar Page" on a broad topic (e.g., "Digital Marketing"), surrounded by smaller "Cluster Pages" that cover specific subtopics (e.g., "Email Marketing," "Social Media Strategy"). The cluster pages should all link back to the pillar page, and the pillar page should link out to the clusters.
