Internal Links and External Links: A Deep Dive
Internal links are hyperlinks on a website that point to other pages within the same domain, while external links are hyperlinks that point to different domains, serving as citations or references.
Introduction: Navigating the Web with Links
The internet is built on connection, and at the heart of this connection lie hyperlinks. They are the roads and bridges of the digital landscape, allowing users to navigate effortlessly between pages and websites. Understanding what are internal links and external links is crucial for website owners, marketers, and anyone seeking to improve their online presence. Links are fundamental to search engine optimization (SEO), user experience (UX), and overall website authority. They act as crucial signals for search engines like Google, helping them to understand the structure, relevance, and trustworthiness of a website.
Internal Links: Weaving Your Website Together
Internal links are like the internal pathways within a city. They connect different parts of the same website, guiding visitors (and search engine crawlers) to relevant content. This is vital for a cohesive user experience and effective SEO.

Benefits of Internal Linking:
- Improved Website Navigation: Helps users easily find related content, increasing time spent on site.
- Enhanced SEO: Signals to search engines the importance and relationship between pages.
- Boosted PageRank: Distributes PageRank (a search engine ranking factor) throughout the website.
- Increased Crawlability: Makes it easier for search engine bots to discover and index all pages.
- Lower Bounce Rate: Keeps users engaged and less likely to leave after viewing only one page.

Best Practices for Internal Linking:
- Use relevant anchor text: The clickable text should accurately reflect the destination page’s content.
- Link contextually: Integrate links naturally within the flow of your content.
- Prioritize high-value pages: Link to pages you want to rank higher in search results.
- Avoid excessive linking: Too many internal links can dilute their effectiveness.
- Monitor and update: Regularly review internal links to ensure they are still relevant and working.
External Links: Connecting to the Wider Web
External links, also known as outbound links, are hyperlinks that point from your website to another website. They are often used to cite sources, provide additional information, or recommend relevant resources. The key thing to consider when wondering what are internal links and external links is that external links always go to a separate domain.
-
Benefits of External Linking:
- Improved Credibility: Linking to authoritative sources enhances your website’s trustworthiness.
- Enhanced User Experience: Provides users with valuable resources and additional information.
- Potential Reciprocal Links: Linking to other websites can sometimes lead to them linking back to you.
- Relationship Building: Can help foster relationships with other websites and industry leaders.
-
Best Practices for External Linking:
- Link to reputable websites: Ensure the websites you link to are trustworthy and authoritative.
- Use relevant anchor text: The clickable text should accurately reflect the destination page’s content.
- Consider “nofollow” links: Use the “nofollow” attribute for links to untrusted sources or paid placements.
- Open external links in new tabs: Prevents users from leaving your website entirely.
- Regularly check for broken links: Ensure your external links are still working.
Dofollow vs. Nofollow Links: Understanding the Attributes
Links have attributes that dictate how search engines should interpret them. The most common are “dofollow” and “nofollow.”
| Attribute | Description | SEO Impact |
|---|---|---|
| Dofollow | Allows search engines to pass PageRank and link juice to the destination website. (Default) | Contributes to the ranking of the linked website. |
| Nofollow | Instructs search engines not to pass PageRank or link juice to the destination website. | Does not directly contribute to the ranking of the linked website, but can still drive referral traffic. |
Understanding the difference between dofollow and nofollow is key when considering what are internal links and external links, and how they impact SEO.

Frequently Asked Questions (FAQs)
What are internal links and external links – here are some answers to your questions!
What is “link juice” and how does it relate to internal and external links?
Link juice is a metaphorical term used to describe the value or authority passed from one website or page to another through hyperlinks. Internal links distribute link juice within a website, strengthening its overall authority. External links (dofollow) pass link juice from the linking website to the destination website, boosting its ranking potential.
How many internal links should I have on a page?
There is no magic number, but aim for a natural and contextual approach. Focus on linking to relevant content that enhances the user experience. Avoid excessive linking, which can dilute the effectiveness of individual links. A good rule of thumb is to link to 2-5 relevant internal pages per 1000 words of content.
Should I always use “dofollow” for internal links?
Yes, you should always use “dofollow” for internal links. There’s essentially no reason to mark an internal link as nofollow, as you want search engines to consider all of your own pages when they are ranking them.
When should I use “nofollow” for external links?
Use “nofollow” for external links in the following situations: sponsored or paid links, links to untrusted or spammy websites, user-generated content (e.g., comments), and affiliate links.
How can I find broken links on my website?
Several tools can help you find broken links, including Google Search Console, Ahrefs, SEMrush, and Screaming Frog. Regularly scanning your website for broken links is crucial for maintaining a positive user experience and SEO.
Does linking to external websites hurt my website’s SEO?
Linking to reputable and relevant external websites actually benefits your website’s SEO. It demonstrates that you are providing valuable resources to your audience and enhances your website’s credibility. The key is to link to high-quality, trustworthy sources.
How important is anchor text for internal and external links?
Anchor text is very important for both internal and external links. It provides context to search engines and users about the destination page. Use descriptive and relevant anchor text that accurately reflects the content of the linked page.
Can I use the same anchor text for multiple internal links?
While you can use the same anchor text for multiple internal links, it’s generally best to vary your anchor text to avoid keyword stuffing and to provide a more natural and diverse linking profile.
How often should I review and update my website’s internal and external links?
You should regularly review and update your website’s internal and external links, ideally on a monthly or quarterly basis. This helps ensure that all links are working, relevant, and pointing to the correct destinations.
What is the difference between a “link building” strategy and simply adding internal and external links to my site?
While simply adding internal and external links will organically improve your site’s SEO over time, link building refers to the active process of getting other websites to link to yours.
How do I ensure that the websites I am linking to are reputable?
Look for websites with high domain authority, good content, and a strong reputation within their industry. Avoid linking to websites that are spammy, low-quality, or contain inaccurate information.
Are there any tools that can help me manage internal and external links more effectively?
Yes, several tools can help you manage internal and external links, including Ahrefs, SEMrush, Google Search Console, Screaming Frog, and Yoast SEO. These tools can help you identify broken links, analyze your linking structure, and track your website’s overall link profile.
