What Are External Links?

External links, also known as outbound links, are hyperlinks that direct users from your website to a different website. For example, when your blog post includes a link to another authoritative site for reference, that's an external link. These differ from internal links, which point users to other pages within your website.

Common types of external links include:

  • Local Citations in blog posts leading to authoritative sources.
  • Links in guest posts directing users to your website.
  • References to brand partners or collaborators.

External links provide additional value to users by offering more in-depth information and context. For SEO professionals, they are vital for fostering trust and credibility within search engine algorithms.

External vs. Internal Links: What's the Difference?

Understanding the distinction between external and internal links is essential for effective SEO strategy. While both are hyperlinks, they serve different purposes and impact your site in unique ways.

External Links

External links are hyperlinks that point users to websites outside of your own domain. These links are incredibly valuable for establishing credibility and trust with search engines. For instance, linking to authoritative sources, such as industry-leading publications or research studies, signals that you’re providing users with well-researched and reliable information. However, it’s important to ensure these outbound links are actively maintained and lead to credible, relevant content, as broken or poor-quality links can negatively affect your site's reputation and SEO performance.

External links also help search engines understand the context of your content. By pointing to relevant and authoritative sources, your content is better positioned to rank higher as search engines consider it more trustworthy and valuable.

Internal Links

Internal links, on the other hand, direct users to other pages within your own website. They are a critical SEO tool for optimizing your site’s structure and navigation. By strategically linking key pages, you can funnel traffic to high-priority content, increase user engagement, and ensure that search engines can effectively crawl and index your site.

For example, an internal link from a blog post to a related service page helps keep users on your site longer and encourages them to explore other areas of your website. This improves metrics like session duration and pages per session, which can positively influence your search rankings. Internal linking also help distribute "link equity" (or ranking power) across your web pages, allowing less-visible pages to gain more authority over time.

Key Differences

  • Purpose: External links connect your content to authoritative outside sources, while internal links tie various pages of your own website together.
  • SEO Impact: External links build credibility and provide additional value to readers, whereas internal links improve site navigation and optimize your website’s structure.
  • Anchor Text: External links often use anchor text describing the linked resource for better context. Internal links, by contrast, typically focus on specific keywords to enhance on-site search rankings.

By integrating both external and internal links thoughtfully into your content, you can improve user experience, enhance your SEO efforts, and create a more cohesive website for both users and search engines.

What Makes an External Link Useful for Sites?

Not all external links are created equal. Google and other search engines evaluate the quality of these links when determining a site's credibility. Here’s what makes a high-quality external link valuable for SEO:

A. Credibility and Trust Markers

Search engines reward content that links to credible, trustworthy sources because these links enhance the overall quality and reliability of your page. A high-quality external link typically comes from an authoritative site—think well-known news outlets, respected academic institutions, government websites, or niche experts in your industry. These sources help signal to search engines that your content is well-researched and credible, which can improve your rankings.

Pro Tip: When sourcing external links, look for websites with high Domain Authority (DA) scores—a metric that reflects the strength of a site’s reputation. Tools like Moz, Ahrefs, or SEMrush can help you measure DA and decide which sites are worth linking to. Avoid linking to low-quality or spammy websites, as these can harm your SEO efforts and make your content appear less trustworthy.

B. The Importance of Relevance

Relevance is king when it comes to external links. While credibility is important, it won’t do much for your SEO if the links you include aren’t relevant to your topic. Google prioritizes links that connect to content closely related to your page’s subject matter. For instance, if you're writing about digital marketing strategies, linking to a bakery's homepage—even if credible—won’t be beneficial. Instead, you should link to resources like industry white papers, marketing blogs, or case studies.

The same principle applies to the anchor text (the clickable text of the link). The anchor text should clearly relate to the content being linked to. For example, instead of using generic phrases like "click here," you might use "best practices for content marketing" if you're linking to an article on that topic. This not only helps readers understand the purpose of the link but also assists search engines in understanding the context, boosting relevance and SEO value.

C. Proper Rel Attributes

Whether you're passing "SEO juice"—or link equity—to the pages you link to depends on the rel attributes you use. These HTML tags define the relationship between your webpage and the destination link. Using the proper attributes ensures you stay compliant with Google’s guidelines while maintaining control over what authority you pass to external sites.

  • DoFollow: Passes authority (or link juice) to the external page, helping it rank better in search results. Use this attribute for trusted and relevant sources you want to endorse. By default, most links are DoFollow unless otherwise specified.
  • NoFollow: Does not pass authority to the linked page. This is useful when linking to pages you cannot fully vouch for, such as random user-generated content, unverified sources, or sponsored material. By including this attribute, you prevent spammy or low-quality sites from benefiting from your link.
  • UGC (User-Generated Content): Indicates that the link comes from content created by users, such as blog comments, forum posts, or reviews. This helps search engines differentiate between editorial content and user-submitted links.
  • Sponsored: Tags links as advertisements or paid placements. Use this when linking to content created as part of a sponsorship or partnership to comply with Google’s transparency guidelines.

Understanding and applying these attributes is crucial for SEO professionals. Not only does it help you stay compliant with Google's rules, but it also allows you to build a more transparent and high-quality linking structure that benefits both your site and your readers.

By combining credibility, relevance, and the correct use of rel attributes, your external links can significantly enhance your content’s value, build trust with your audience, and boost your SEO performance.

Are External Links Helpful for SEO?

The short answer is: Absolutely. Here's why external links are beneficial for SEO:

  • Improves Search Engine Rankings: Google considers external links as an indicator of your content's reliability and relevance. By linking to reputable and trustworthy sources, you signal to search engines that your content is well-researched and authoritative. This can boost your article's ranking potential, making it more visible to your target audience.
  • Enhances User Experience: External links enrich your content by providing readers with additional value. They can dive deeper into related topics, explore further details, or gain new perspectives from the linked resources. This not only keeps users engaged but also establishes your site as a helpful and resourceful destination.
  • Builds Relationships and Backlinks: Linking to authoritative websites can open the door for building mutually beneficial relationships. When you acknowledge other experts by linking to their content, they may notice and be inclined to link back to you in the future. This exchange of backlinks strengthens your SEO strategy and expands your reach.
  • Adds Context to Content: External links serve as evidence to support your claims, giving your content credibility and depth. By directing readers to relevant studies, articles, or statistics, you provide solid proof to back up your ideas, making your arguments more persuasive and trustworthy.

How to Find External Links for Your Website?

Sourcing external links strategically is key to making the most of what they offer. Here are practical ways to find great links for your website:

  • Research Industry-Leading Publications: Explore websites like Forbes, HubSpot, or TechCrunch, which are known for publishing high-quality, trusted content on a wide range of topics. These sources often provide valuable insights and up-to-date information that can strengthen your content and make it more credible.
  • Leverage Research Tools: Use tools such as BuzzSumo and SEMrush to identify trending articles, widely shared content, and top-performing resources relevant to your niche. These tools can help you stay ahead of industry trends and ensure your external links are both relevant and valuable to your audience.
  • Consult Authoritative Studies: Look for peer-reviewed journals, government websites, and well-researched academic papers to back up your claims. These sources add a layer of authority and trust to your content, ensuring your readers view your work as reliable and well-informed.
  • Engage with Experts: Reach out to industry experts for interviews or insights, or quote their published work to enrich your content. Linking back to their websites not only provides value to your audience but can also help build connections and improve your own website’s credibility within your field.

Remember, the goal is to link only when it genuinely adds value—not to shoehorn irrelevant references for the sake of SEO.

How to Master External Linking Best Practices?

  • Be Selective: Only include external links when they add direct value or context to your content.
  • Focus on Quality: Prioritize links to authoritative, relevant sources in your industry.
  • Use Variety: Avoid over-reliance on a small pool of link sources to prevent patterns that might look unnatural to search engines.
  • Apply Rel Attributes Wisely: Make sure to use the correct HTML attributes to clarify the purpose of each external link.
  • Monitor Regularly: Audit your links periodically to identify broken or low-value external links.

Monitoring and Fixing External Links

Beyond adding external links, ongoing maintenance is a crucial part of your SEO efforts. Over time, external links can become broken or outdated, leading to errors that frustrate users and harm your SEO. Here's how to stay on top of them:

  • Use Automated Tools: Tools like Screaming Frog or Ahrefs make monitoring broken links simple. These platforms can regularly audit your site and highlight any broken outbound links that need fixing.
  • Redirect Where Possible: When links break due to changes in the linked site, set up a redirect if you have control over the destination. Alternatively, search for updated content on the same site.
  • Replace Carefully: When replacing unusable external links, opt for trustworthy alternatives tied closely to the original context. Never settle for low-quality sources.
