Introduction: Why External Linking Is One of the Most Underrated SEO Moves
Most beginners obsess over writing great content. That is a smart move. But there is one thing they keep ignoring that can seriously hurt their SEO — external linking.
External linking best practices are not just for big-budget marketers or tech-savvy SEO experts. Whether you run a personal blog, a freelance portfolio, a side hustle website, or an online store, understanding how to link out to other websites correctly can make a huge difference in how Google ranks your content.
In this guide, you will learn exactly what external linking is, why it matters, and how to do it the right way — step by step, in plain English.
No jargon. No confusion. Just clear, actionable advice.
This guide is part of our SEO category, where you’ll find tutorials on keyword research, technical SEO, internal linking, and growing organic traffic.
What Is External Linking? (And How Is It Different from Internal Linking?)
Before we dive into best practices, let us make sure we are on the same page.
External linking (also called outbound linking) is when your website links to another website. For example, if you write a blog post about nutrition and link to a Harvard study about vitamins, that is an external link.
Internal linking, on the other hand, is when you link from one page on your own website to another page on the same website.
Here is a quick comparison:
- External link: Your blog → Someone else’s website
- Internal link: Your blog post → Another post on your blog
Both types matter for SEO. But today, we are focusing on external links — and why getting them right is a game-changer.
Why External Linking Best Practices Matter for SEO
You might be wondering: why would I want to send my visitors to someone else’s website?
That is a fair question. Here is the honest answer.
Google does not just care about what is on your page. It also looks at how your page connects to the broader web. When you link to high-quality, trustworthy sources, you are essentially telling Google: “I care about accuracy. I want my readers to have the full picture.”
That builds trust. And trust is exactly what Google rewards with higher rankings.
Here are the real benefits of following external linking best practices:
- Improves your content’s credibility — Citing trusted sources makes your claims more believable
- Signals trustworthiness to Google — Search engines use links to understand context and quality
- Enhances user experience — Readers can dig deeper into topics they care about
- Reduces bounce rate — Quality resources keep visitors engaged longer
- Supports your E-E-A-T score — Google measures your Experience, Expertise, Authoritativeness, and Trustworthiness
Bottom line: smart external linking makes both Google and your readers trust you more.
The Golden Rules of External Linking Best Practices
Let us get into the practical stuff. These are the core rules every blogger, freelancer, and online entrepreneur needs to follow.
1. Always Link to High-Authority, Trustworthy Sources
This is rule number one, and it is non-negotiable.
Not all websites are created equal. Linking to low-quality, spammy, or outdated websites can actually hurt your SEO. Google evaluates the quality of the sites you link to.
Good sources to link to:
- Government websites (.gov)
- Educational institutions (.edu)
- Established news organizations (BBC, Reuters, Forbes)
- Industry-leading publications (HubSpot, Neil Patel, Moz)
- Peer-reviewed research and studies
Sources to avoid linking to:
- Spam websites with thin or copied content
- Sites with lots of pop-up ads and clickbait
- Websites that are not related to your topic
- Sites with a low domain authority or bad reputation
- Pages that have not been updated in years
Example: If you are writing about social media marketing, linking to Sprout Social or Buffer’s blog is a smart move. Linking to a random personal blog with no credentials? Not so much.
2. Make Sure Every External Link Is Relevant
Relevance is everything in SEO.
Your external links should directly support what you are talking about in that section of your post. A random link that does not match the content confuses both readers and search engines.
Ask yourself this before adding any external link: Does this link add value to what I am explaining right now?
If the answer is no, skip it.
Example: You are writing about how to start a freelance writing career. Linking to a U.S. Bureau of Labor Statistics report on writer employment makes perfect sense. Linking to a cooking recipe website does not — even if it is a high-authority site.
3. Use Descriptive Anchor Text (Not “Click Here”)
Anchor text is the clickable words in a hyperlink. This is one of the most overlooked external linking best practices among beginners.
Using vague phrases like “click here” or “read more” tells Google nothing. Instead, use anchor text that clearly describes what the linked page is about.
Bad anchor text examples:
- “Click here to learn more”
- “Read this article”
- “Visit this website”
Good anchor text examples:
- “a 2023 study on content marketing ROI”
- “Google’s official Search Quality Evaluator Guidelines”
- “HubSpot’s guide to email marketing”
Descriptive anchor text helps Google understand the context of the linked page. It also helps your readers know exactly what they will find when they click.
4. Open External Links in a New Tab
This is a simple but powerful trick.
When someone clicks an external link and it opens in the same tab, they leave your website. You lose them. But if the link opens in a new tab, your website stays open in the background. The reader can check the external resource and come back to finish your article.
In HTML, you do this by adding target="_blank" to your link tag. Most website builders like WordPress, Wix, and Squarespace have a simple checkbox for this in the link settings.
Why it matters: Keeping visitors on your site longer improves your engagement metrics, which signals to Google that your content is valuable.
5. Do Not Over-Link — Quality Over Quantity
There is no perfect number of external links per post. But there is such a thing as too many.
If every other sentence has an external link, it can make your content feel scattered and untrustworthy. It can also confuse Google about what your page is actually about.
A good rule of thumb is to add 2 to 5 external links per 1,000 words — but only when they genuinely add value.
Focus on:
- One or two links to major authoritative sources
- Links that back up statistics or bold claims
- Links to tools or resources your readers actually need
6. Use the “nofollow” or “sponsored” Tag When Necessary
This is a slightly more technical tip, but it is important.
By default, when you link to another website, you pass some of your website’s “link juice” (SEO authority) to that site. Sometimes, you do not want to do that.
Here are the link types Google recommends tagging:
- rel=”nofollow” — Use this for links you do not want to endorse, like user-generated content or links in comments
- rel=”sponsored” — Use this for any paid or affiliate links
- rel=”ugc” (User Generated Content) — Use this for links in forums, comments, or community posts
Warning: If you are an affiliate marketer or blogger who earns commission from links, not using the “sponsored” tag can get you penalized by Google. Always disclose affiliate relationships. It is both an SEO best practice and a legal requirement in many countries.
7. Check Your External Links Regularly
Links go dead. Websites shut down. Pages move.
A broken external link (also called a dead link) sends your readers to a 404 error page. This is terrible for user experience and can hurt your SEO score over time.
Make it a habit to audit your external links every 3 to 6 months. Tools that can help:
- Broken Link Checker (free WordPress plugin)
- Ahrefs Site Audit (paid but powerful)
- Screaming Frog (free version available)
- Google Search Console (free and built by Google)
Fix or remove any broken links you find. Your readers and your rankings will thank you.
8. Avoid Linking to Direct Competitors
This one requires some business thinking, not just SEO thinking.
If you are a freelance copywriter, linking to another freelance copywriter’s services page is essentially sending potential clients to your competition. That is rarely a smart move.
However, linking to industry publications, research studies, and non-competing resources in your niche is completely fine — and encouraged.
The rule: Link to resources that help your readers, not to websites that compete directly for the same customers or traffic you are after.
Common External Linking Mistakes Beginners Make
Even people who know the basics mess these up. Watch out for these common errors:
- Linking to irrelevant pages just to seem thorough
- Using exact match anchor text every single time (this looks spammy to Google)
- Forgetting to check if a source is current — a 2015 statistic presented as fact in 2025 misleads readers
- Linking to the homepage instead of the specific page that covers the topic you are referencing
- Not disclosing paid or affiliate links — this can get you penalized or even sued
- Never updating old posts — broken links pile up over time if you do not do regular audits
External Linking and Monetization: What You Need to Know
If you are building a blog or website to make money online, external linking plays a big role in your monetization strategy.
Here is how:
Affiliate marketing: You link to products or services, and you earn a commission when someone makes a purchase through your link. Always use rel="sponsored" and disclose the relationship.
Sponsored content: Brands pay you to link to their pages in your posts. Again, always use the sponsored tag and be transparent with your audience.
Building relationships: Linking to other creators and businesses can open doors. Many bloggers and entrepreneurs have formed partnerships, collaborations, and joint ventures simply because one person linked to another’s work and reached out.
One big warning: Avoid paid link schemes where someone pays you to insert links in your content without disclosure. Google’s guidelines explicitly prohibit this, and getting caught can lead to a serious drop in rankings — or complete removal from search results. It is not worth it.

Frequently Asked Questions (FAQs)
Q1: What is external linking in SEO?
External linking refers to placing links on your website that point to other websites. These links help Google understand your content’s context and signal that you are citing trustworthy sources. Following external linking best practices improves your site’s credibility and search rankings.
Q2: How many external links should I include in a blog post?
A good guideline is 2 to 5 external links per 1,000 words. Focus on quality over quantity. Every link should add genuine value to the reader and support a specific claim or point in your content.
Q3: Should I use nofollow on all external links?
No. Only use nofollow for links you do not want to endorse, like user-generated content, untrusted sources, or links in comment sections. Regular editorial links to trusted sources do not need a nofollow tag.
Q4: Does linking to other websites hurt my SEO?
No — if done correctly, it actually helps. Linking to authoritative, relevant sources improves your content’s credibility. What hurts your SEO is linking to low-quality, spammy, or irrelevant websites.
Q5: What is the difference between dofollow and nofollow links?
A dofollow link passes SEO authority from your site to the linked site. A nofollow link tells Google not to follow the link or pass authority. Use dofollow for trusted editorial links and nofollow for paid, untrusted, or user-generated content links.
Q6: Can broken external links hurt my website’s ranking?
Yes. Broken links create a poor user experience and can signal to Google that your site is outdated or poorly maintained. Audit your links every 3 to 6 months to find and fix any dead links.
Q7: Is it okay to link to competitor websites?
Linking to competitor websites that offer the same products or services as you is generally not recommended. However, linking to non-competing websites in your industry — like industry blogs, research organizations, or news publications — is perfectly fine and often beneficial for your SEO.
