What is Interlinking in SEO?

Interlinking is the practice of linking one page of a website to another page within the same domain.

Interlinking is a fundamental aspect of website architecture and Search Engine Optimization (SEO). Proper interlinking enhances user experience, improves site navigation, and boosts your website’s SEO performance. This guide will dive into what interlinking is, why it’s essential, its effects on SEO, best practices, examples, and the do’s and don’ts of interlinking.
 

What is Interlinking?

Interlinking, also known as internal linking, refers to the practice of linking one page of a website to another page within the same domain. These links are different from external links, which point to pages on different websites. Interlinking helps users navigate a website and allows search engines to understand the structure and content hierarchy of the site.
 

Why is Interlinking Important?

User Experience Enhancement

  • Navigation Aid: Interlinks guide users to related content, enhancing their browsing experience.
  • Content Discovery: Helps users find valuable information they might not have encountered otherwise.
  • Engagement: Encourages users to spend more time on your site, exploring various pages.
 

SEO Benefits

  • Crawling Efficiency: Search engine bots use links to crawl websites. Interlinking ensures bots can find and index all your important pages.
  • Link Equity Distribution: Spreads link authority (also known as “link juice”) throughout your site, improving rankings.
  • Keyword Context: Anchor texts provide context to search engines about the linked page’s content.
 

Effects of Interlinking on SEO

Improved Crawling and Indexing

  • Accessibility: Ensures all pages are accessible to search engine crawlers.
  • Indexation: Pages linked internally are more likely to be indexed by search engines.
  • Crawl Budget Optimization: Efficient interlinking helps search engines crawl your site more effectively, making better use of your crawl budget.
 

Distribution of Link Equity

  • Authority Sharing: High-authority pages can pass some of their link equity to other pages through interlinks.
  • Ranking Improvement: Pages receiving more internal links may rank higher in search results.
 

Keyword Optimization

  • Anchor Text Relevance: Using keyword-rich anchor texts signals to search engines the topic of the linked page.
  • Contextual Relevance: Helps search engines understand the relationship between pages.
 

Reduced Bounce Rate

  • User Engagement: Interlinking keeps users on your site longer by providing additional relevant content.
  • Behavioural Signals: Lower bounce rates and higher session durations can positively influence SEO.
 

Best Practices for Interlinking

  1. Use Descriptive and Relevant Anchor Text
    • Clarity: Anchor text should clearly describe the content of the linked page.
    • Keyword Inclusion: Include relevant keywords naturally within the anchor text.
    • Avoid Generic Phrases: Steer clear of non-descriptive terms like “click here” or “read more.”
  2. Example:
    • Instead of: “For more information, click here.”
    • Use: “Learn more about our digital marketing services.”
  3. Link to Relevant Content
    • Contextual Relevance: Ensure the linked pages are relevant to the content of the current page.
    • Value Addition: Links should provide additional value to the reader.
  4. Create a Logical Site Structure
    • Hierarchical Organization: Structure your site in a logical hierarchy with categories and subcategories.
    • Siloing: Group related content together and link within these groups to strengthen topic authority.
  5. Update Old Content with New Links
    • Content Refresh: Revisit older posts to add links to newer relevant content.
    • Maintain Relevance: Keeps all content interconnected and up-to-date.
  6. Limit the Number of Links per Page
    • Avoid Overloading: Too many links can dilute link equity and overwhelm users.
    • Quality Over Quantity: Focus on linking to the most relevant and valuable pages.
  7. Recommendation: Aim for no more than 100 internal links per page, but adjust based on content length and user experience.
  8. Use Follow Links
    • Default Setting: By default, links are “follow,” allowing search engines to pass link equity.
    • Avoid Nofollow on Internal Links: Do not use the rel="nofollow" attribute on internal links you want indexed.
  9. Ensure Mobile-Friendly Interlinking
    • Responsive Design: Links should be easily clickable on mobile devices.
    • Avoid Tiny Click Areas: Ensure links are large enough to tap without zooming.
 

Examples of Effective Interlinking

  • Wikipedia: Each article contains numerous internal links to related topics, enhancing user engagement and SEO.
  • E-commerce Sites: Product pages link to related products, categories, and recommended items.
  • Blogs: Articles link to other relevant posts, categories, and tags to encourage further reading.
