How to Add External Links

Adding external links to your website is a fundamental aspect of content creation and on-page SEO. These links point to other websites, expanding your content's reach and providing valuable resources for your audience. When done correctly, external linking can significantly boost your website's authority, credibility, and search engine rankings. This guide will walk you through the best practices for incorporating external links effectively.

Understanding External Links

An external link, also known as an outbound link, is a hyperlink that directs users from your website to another domain. Unlike internal links that connect pages within your own site, external links lead to content hosted elsewhere on the internet.

Why Are External Links Important?

External links serve multiple crucial purposes:

  • Enhancing User Experience: They provide users with access to supplementary information, data, or resources that you may not have covered in detail on your own page. This can lead to increased engagement and satisfaction.
  • Building Authority and Credibility: Linking to reputable and authoritative sources demonstrates that you've done your research and are providing well-supported information. This can transfer some of that authority to your own content.
  • Supporting Your Content: Citing sources strengthens your arguments and makes your content more trustworthy.
  • Improving SEO: Search engines like Google interpret external links as signals of quality and relevance. When you link to high-quality, relevant external sites, you're essentially telling search engines that your content is well-researched and part of a broader online conversation.
  • Establishing Relationships: While not a direct SEO benefit, linking to other sites can foster goodwill and potentially lead to reciprocal linking opportunities down the line.

Best Practices for Adding External Links

Simply adding links isn't enough; you need to do it strategically. Here are the key best practices to follow:

1. Link to Authoritative and Relevant Sources

This is perhaps the most critical aspect of external linking. Always link to websites that are:

  • Reputable: Choose established, trustworthy sources. Think of well-known publications, academic institutions, government sites, or leading industry experts.
  • Relevant: The linked content should directly support or expand upon the topic you're discussing. Irrelevant links can confuse users and harm your SEO.
  • High-Quality: Ensure the external content is well-written, accurate, and up-to-date.

Avoid linking to:

  • Spammy or low-quality websites.
  • Websites with excessive ads or pop-ups.
  • Sites that are not relevant to your content.

2. Use Descriptive and Natural Anchor Text

Anchor text is the clickable text of a hyperlink. The anchor text should accurately describe what the user will find on the linked page.

  • Be Specific: Instead of "click here," use something like "learn more about [topic]" or "view the full report."
  • Avoid Generic Phrases: "Read more," "visit this site," or "link" are not descriptive.
  • Incorporate Keywords (Naturally): If a keyword naturally fits the description of the linked content, use it. For example, if you're discussing the importance of site structure, you might link to an article about what is product url structure.
  • Vary Your Anchor Text: Don't use the exact same anchor text for every link to the same external site.

3. Open External Links in a New Tab

By default, links open in the same browser tab, replacing your current page. For external links, it's generally best practice to have them open in a new tab.

  • Preserves User Session: This allows users to visit the external resource without leaving your site. They can easily return to your page when they're done.

  • How to Implement: Most content management systems (CMS) like WordPress have a checkbox option when you're adding a link to "open in new tab." If you're using HTML, you'll add the target="_blank" attribute to your anchor tag:

    <a href="https://www.example.com" target="_blank">Descriptive Anchor Text</a>
    

4. Use rel="noopener" and rel="noreferrer" Attributes

When you use target="_blank", it's a good security practice to also include rel="noopener" and rel="noreferrer".

  • rel="noopener": Prevents the new page from having access to the window.opener property of the original page, which can prevent security vulnerabilities like tabnabbing.
  • rel="noreferrer": Prevents the browser from sending the originating page's address (your site's URL) to the new page. This is good for privacy and can help prevent referral spam.

Your HTML link would look like this:

<a href="https://www.example.com" target="_blank" rel="noopener noreferrer">Descriptive Anchor Text</a>

Most modern CMS platforms automatically add these attributes when you select the "open in new tab" option, but it's good to be aware of them.

5. Link Strategically, Not Excessively

While external links are beneficial, overdoing it can be detrimental.

  • Quality over Quantity: Focus on adding links only when they genuinely add value to the reader.
  • Avoid Link Stuffing: Don't sprinkle links everywhere just for the sake of it. This can make your content look spammy and distract readers.
  • Context is Key: Ensure each link is placed within a relevant sentence or paragraph where it makes logical sense. For instance, when discussing internationalization strategies, you might link to information about what is hreflang tag.

6. Consider the "YMYL" Factor

For certain topics, particularly those related to health, finance, or safety, search engines place a higher emphasis on expertise, authoritativeness, and trustworthiness (E-A-T). When linking to external sources on these sensitive topics, ensure they are exceptionally authoritative and reliable. Understanding what is ymyl expertise is crucial here.

7. Don't Link to Competitors Unnecessarily

While linking to a competitor might seem counterintuitive, there are rare instances where it can be appropriate, such as citing a statistic or a definitive guide they've published. However, be very selective. If your content is comprehensive, you might not need to link out to them at all.

8. Link to Diverse Sources

Don't just link to one or two websites. Diversifying your external links shows that you're drawing information from a broad range of reputable sources. This reinforces your content's credibility.

9. Understand Searcher Behavior

When users are searching for information, they often have specific questions or needs. Your external links should help satisfy those needs by providing further clarity or depth. Understanding what is searcher behavior can inform your linking strategy.

10. Check Your Links Periodically

Broken links are a common problem. Regularly audit your website to ensure all your external links are still active and pointing to the correct pages. Broken links frustrate users and can negatively impact your SEO.

11. Don't Be Afraid to Link to High-Quality Multimedia Content

If a relevant, high-quality video, infographic, or interactive tool exists on another site, consider linking to it. This can enrich your content and provide a more engaging experience for your audience, much like linking to what is multimedia content on a related topic.

The Impact of External Links on SEO

Search engines use a variety of signals to rank web pages, and external links play a significant role.

  • Link Equity (PageRank): While the exact algorithms are proprietary, the concept of PageRank suggests that links passing authority from one page to another. When you link to authoritative sites, you're essentially vouching for them, and in turn, receiving a small boost from their authority.
  • Topical Relevance: Linking to relevant external pages helps search engines understand the topic of your page more precisely. If your page is about baking, and you link to a reputable source on yeast, it reinforces that your page is indeed about baking.
  • User Engagement Signals: If users click on your external links and spend time on the linked pages, it can signal to search engines that your content is valuable and helpful. Conversely, if they immediately return to your page (a "pogo-stick" effect), it might suggest the external link wasn't a good fit.

Tools to Help Manage External Links

  • Broken Link Checkers: Tools like Ahrefs, SEMrush, or free online checkers can help you identify broken external links on your site.
  • SEO Audit Tools: Comprehensive SEO audit tools often include checks for external link quality and quantity.

Common Mistakes to Avoid

  • Linking to Low-Quality or Spammy Sites: This is the fastest way to damage your own site's reputation and SEO.
  • Using Generic Anchor Text: "Click here" offers no SEO value and is poor for user experience.
  • Not Using target="_blank": For external links, this is generally a user experience must-have.
  • Linking to Competitors Too Often: Unless it's absolutely necessary and beneficial to the user, avoid it.
  • Ignoring Broken Links: These are detrimental to both user experience and SEO.

Frequently Asked Questions about External Links

What is the difference between internal and external links?

Internal links connect pages within your own website, helping users navigate your site and aiding search engines in understanding your site structure. External links, on the other hand, point to content on completely different websites.

How many external links should I include on a page?

There's no magic number. The focus should be on quality and relevance. Include external links only when they genuinely add value to your content and provide additional resources for your readers. Avoid overstuffing your pages.

Can linking to external websites hurt my SEO?

Yes, it can if you link to low-quality, irrelevant, or spammy websites. However, linking to authoritative, relevant, and high-quality external resources is generally beneficial for your SEO.

For external links, it's highly recommended. This opens the link in a new browser tab, allowing users to visit the external resource without leaving your website, thus improving user experience.

What are the security implications of using target="_blank"?

Using target="_blank" alone can create a security vulnerability known as tabnabbing. To mitigate this, it's best practice to also include rel="noopener" and rel="noreferrer" attributes in your link tags.
