What are internal links?  

Internal links are hyperlinks that connect one page on a website to another page on the same domain. They help users navigate your site and allow search engine crawlers to discover, index and understand your content.  

Internal links help search engines and users find your most valuable content.

Internal links also pass link equity, highlight important pages and strengthen your overall site structure. Unlike external links, which point to other websites, internal links keep traffic flowing through your own pages—improving engagement and SEO. 

What is the difference between internal and external links? 

The main difference between internal and external links is where they point. Internal links connect pages within the same website, while external links point to other websites. 

Internal links help guide users and search engines through your site, improve your internal linking structure and pass value to important pages. In contrast, external links direct visitors away from your site and often serve to reference or cite sources from trusted domains. 

Both types are important—internal and external links work together to improve SEO, boost authority and enhance the user experience. 

What are the types of internal links? 

Not all internal links are created equal. On a typical website, internal links appear in different places and serve different purposes. From guiding navigation to boosting SEO, each type plays a unique role in your internal linking strategy.  

Here’s a quick breakdown: 

1. Navigational  
2. Contextual  
3. Footer  
4. Sidebar  

Let’s look at each type in detail. 

1. Navigational  

These are the links you see in your website’s main menu or header. Navigational links help users move through your site’s main navigation, making it easy to find important pages like your homepage, blog or contact page. They also help search engines understand your site structure and hierarchy. 

Example: A top menu link to “Blog,” “Services” or “Contact Us.” 

2. Contextual  

Contextual links appear within the body of your content—like blog posts or landing pages. They connect relevant pages using descriptive anchor text, guiding readers to related content and passing link equity to key pages. This type of link is especially valuable for SEO, as it helps search engines understand how your website pages relate to each other. 

Example: A blog post on SEO linking to another post titled “How to Do Keyword Research.” 

3. Footer  

Footer links are found at the bottom of a web page. They often link to essential information like privacy policies, terms of service or important pages you want users and search spiders to access easily. While they don’t carry as much link value as contextual links, they still support your crawlable link structure. 

Example: Links to “Privacy Policy,” “Terms of Service” or “Sitemap” in the footer section. 

4. Sidebar  

Sidebar links typically appear alongside your main content. They might point to recent posts, categories or high authority pages you want to highlight. These internal links can increase visibility for other internal pages and reduce crawl depth, helping both users and bots find deeper pages more efficiently. 

Example: A “Popular Articles” or “Related Posts” section in the blog sidebar. 

What is the importance of internal linking for SEO?

Internal linking is vital for SEO because it helps search engines crawl and index your website, improving rankings. Internal links connect related pages, making it easier for search engine crawlers to discover and prioritize important content. They also help distribute link equity, passing value from high-authority pages to others. Additionally, internal links improve user experience by keeping visitors on your site longer and guiding them to relevant content, which reduces bounce rates and boosts engagement.  

The right internal linking strategy turns traffic into conversions by guiding users across your site.

Keep in mind that adding internal links to your WordPress website is a simple process but holds high value. 

What are the best practices for internal linking? 

To get the most out of your internal linking strategy, follow these key best practices. They will help improve both user experience and SEO, ensuring that your site is easy to navigate and search engines can crawl it effectively. 

• Link to relevant pages: Direct users and search engines to related content on your site. 
• Use clear anchor text: Make sure the text you link is descriptive and explains what the linked page is about. 
• Don’t overload with links: Keep the number of links reasonable and focus on linking to important pages. 
• Ensure links are crawlable: Avoid no follow tags and broken links to make sure your pages are indexed correctly. 
• Regularly audit your links: Check for broken links and fix them to maintain a smooth linking structure. 
• Keep site navigation simple: Organize your content logically so both users and search engines can easily find related pages.

How to find internal linking opportunities?  

Finding the right internal linking opportunities is essential to creating a strong SEO strategy. By identifying relevant pages that can be linked to one another, you can improve site navigation, boost page authority and enhance user experience. 

• Analyze existing content: Review your current content for gaps where internal links could provide value. Look for articles or pages that mention topics covered on other pages and link them. 
• Use a site audit tool: Tools like Google Search Console, Screaming Frog or Ahrefs can help you find pages with few or no internal links. These “orphan” pages are great candidates for internal linking. 
• Link to high-authority pages: Identify your highest-ranking pages and ensure they link to important, related content on your site. This passes link equity to those pages. 
• Review top-performing content: Find your most popular content based on traffic or conversions. Look for opportunities to link from these pages to less popular but relevant content. 
• Use keyword research: Conduct keyword research to identify pages targeting similar or complementary keywords. These can serve as great internal linking opportunities. 

How to build an effective internal linking strategy?

Building an effective internal linking strategy is key to improving SEO, increasing page visibility and enhancing user experience. By linking your content strategically, you can guide both users and search engines through your site in a meaningful way. 

• Create a logical site structure: Organize your content in a way that makes sense to users and search engines. Group related topics together and ensure there’s a clear hierarchy, with key pages easily accessible. 
• Prioritize important pages: Identify the most valuable pages on your site (e.g., high-converting or high-ranking pages) and make sure they receive the most internal links. This will help pass link equity and boost their visibility. 
• Use descriptive anchor text: Choose anchor text that clearly describes the content of the linked page. This helps both users and search engines understand the relevance of the linked page. 
• Limit the number of links per page: Avoid overwhelming users and search engines with too many links. Keep it focused on the most relevant pages to maintain a clear, easy-to-follow internal linking structure. 
• Maintain a balance between internal and external links: While internal links are crucial for SEO, don’t neglect external links. Ensure you link to authoritative external resources where appropriate but keep the majority of links internal. 
• Regularly update and audit your links: Over time, some links may become broken or outdated. Regularly audit your internal links to ensure they’re working and point to the right pages.

What are some common internal linking mistakes to avoid? 

Internal linking is a powerful SEO tool, but it’s easy to make mistakes that can hinder your site’s performance. Here are some common errors to avoid when building your internal linking strategy. 

• Overlinking or excessive links on a page: Too many internal links on a single page can overwhelm both users and search engines. This can dilute the link equity and reduce the overall effectiveness of your links. Keep it balanced and relevant. 
• Using generic anchor text: Using vague anchor text like “click here” or “read more” doesn’t give search engines or users any indication of the linked page’s content. Always use descriptive, keyword-rich anchor text. 
• Ignoring broken links: Broken internal links can negatively impact both user experience and SEO. Regularly audit your site to ensure all links are functioning correctly. 
• Not linking to important pages: Failing to link to your high-value pages can make it harder for search engines and users to find them. Make sure you are linking to your most important content, such as high-converting pages or cornerstone content. 
• Overusing exact match anchor text: While using keyword-rich anchor text is important, overusing exact match keywords can appear unnatural to search engines. Aim for variety to avoid penalties. 
• Not having a clear site structure: A disorganized internal linking structure can confuse users and search engines alike. Ensure your content is grouped logically, with a clear hierarchy that allows for easy navigation and efficient crawling. 
• Forgetting to update links: As your site grows, old content may become outdated and new content may require internal links. Always keep your internal linking strategy updated to ensure new pages are properly linked and older pages remain relevant.
