Internal and external links can make or break your website’s search visibility — yet many site owners still misuse them or overlook them completely.

In this guide, you’ll learn exactly what internal and external links are, how they affect your SEO, and how to build a smart linking strategy that improves both rankings and user experience. 

What Is Internal Link and External Link? Full SEO Guide & Benefits

8 SEO Benefits of Internal Links (With Real Examples)

Before we get into strategies and best practices, let’s break down what are internal link and external link and how they fit into your SEO link building strategies.  

1. What is an Internal Link?

An internal link is basically your website talking to itself—but in a productive, healthy way. It’s a hyperlink that points from one page to another within the same domain. You know, the digital version of “Hey, if you liked this, you’ll love my cousin over here!”

Example: <a href=”http://www.same-domain.com/” title=”Keyword Text”>Keyword Text</a>

A blog post linking to another related article on the same website is using an internal link

Types of Internal Links (aka “the squad”):

• Navigation links – The menu items that say “Click me or be lost forever.”

• Footer links – For the overachievers who scroll all the way down.

• Contextual links – Hidden gems inside your actual content, linking to stuff people might actually want.

Why Do Internal Links Matter?

• Google’s personal GPS: Helps the almighty bot army figure out where things are and how they’re connected.

• Content Hierarchy: It’s like telling Google, “This page is Beyoncé, and this one is Michelle.”

• Link Equity Redistribution: Got a strong page? Use it to prop up your awkward, overlooked blog posts. It’s charity with SEO benefits.

2. What is an External Link?

Let’s talk about external links—those hyperlinks that take your readers away from your website, like sending them on a quick field trip… hopefully not to a sketchy alley on the internet.

These are the links pointing to a whole different domain. Not your turf. Someone else’s house. Ideally, a really nice, reliable house with a clean URL and good snacks.

External links are mostly used for providing references, citations, or supplementary material

For example: <a href=”http://www.external-domain.com/”>Anchor Text Example</a> You use them when you say: “Hey, I’m not just making stuff up—look, this smart person agrees with me.”

Common Types of External Links

Now, not all external links are the same. Depending on how they’re used—and how you label them—they can send very different signals to search engines. Here are a few types you’ll probably come across:

• GC (User-Generated Content) Links: These are links that come from people who leave comments like “Nice article! Check out my NFT project [link].” That’s why you slap a rel="ugc" on it, so Google knows you didn’t personally vouch for this random internet goblin.
• Sponsored Links: You got paid to place that link? Cool. Just tell Google with rel="sponsored". Transparency is hot. It’s also required.
• DoFollow Links: These are the default. They say, “Yes, I recommend this link, pass along some SEO juice.” Great for the one being linked, and risky if you’re linking to dodgy websites. Choose your friends wisely.
• NoFollow Links: Like saying: “Here’s a link but don’t trust it too much.” Useful for sketchy sources, affiliate stuff, or just when you’re emotionally unavailable.

Why it’s important:

• Increases credibility: When you link it to relevant and authoritative sources, you build more trust now and improve its value.
• Signals content relevance to search engines: Google and other search engines use external links because they signal content relevance to help them understand your content’s context and trustworthiness.
• Supports a stronger backlink profile (when others link to your site in return): To link to other people encourages reciprocal linking. This strengthens your backlink profile with improved SEO, supporting a stronger backlink profile when others link to your site in return.

8 Benefits of Internal Links for SEO

SEO benefits of internal links: improved rankings, longer user sessions, link equity distribution, and better site structure

A well-structured internal linking strategy is key toward this impact. These eight important advantages get consideration to stress value.

• Clarify Site Structure for Google: Internal links help search engines understand the relationship between pages. They show which content is connected and how your site is organized.
• Improve Crawling and Indexing: Linking to new or important content from existing pages makes it easier for search engines to discover and index your updates faster.
• Distribute Page Authority (Link Equity): When a high-authority page links to a lower-performing one, it passes some of its SEO value, helping boost rankings and visibility across your site.
• Enhance User Experience: Smart internal linking helps visitors find relevant content without having to dig. It encourages them to explore more of your site organically.
• Reduce Bounce Rate and Increase Time on Site: When people find more useful content through links, they stay longer and interact more. This is a positive engagement signal to search engines.
• Strengthen Website Architecture: A clear internal link structure supports a strong content hierarchy. It makes your site easier to navigate and more logical to both users and search engines.
• Support Keyword Targeting: When you use anchor text with keywords, it tells Google what the linked page is about giving it a better shot at ranking for those terms.
• Improve Long-Tail Keyword Rankings: Internal links can help surface niche pages that target very specific search queries, boosting your chances of showing up in more detailed searches.

Tips on How To Use Internal and External Link Effectively

Using Internal and External Link Effectively

Whether you’re working on internal or external link building, the right strategies are key to SEO success. 

1. Internal Linking Strategy

Content Hub Structure: Create pillar pages with topic clusters that link to and from each other. Learn how create your first content hub in our article: How to Create a Content Hub: Step-by-Step Guide

Contextual Relevance: Only link related pages with natural, descriptive anchor text. Like the internal link about “content hub” you see above.

Orphan Page Fixing: Ensure all pages are linked from somewhere within the site. If you have an old campaign landing page that still has SEO value, find relevant blog posts to link to it.

Navigation Optimization: Use sidebar, footer, and breadcrumb links to support core site structure. For example, a product page might use breadcrumbs like Home > Collection > Women’s Shoes to help users navigate where they are.

Update Old Content: Revisit high-performing older posts and add internal links to newer, relevant content. This helps maintain their authority and keeps them SEO-relevant.

Full Control: You choose the anchor text, target page, and context. That’s a big advantage of internal links over backlinks, which are often out of your hands.

Clarify Site Hierarchy: Helps search engines understand your website’s structure. Tip: A clear internal linking structure increases the chances of Google displaying sitelinks beneath your listing, which improves visibility and CTR.

Keyword Targeting: Select keywords carefully in anchor texts for better SEO relevance. Mixing exact-match keywords with semantic alternatives helps you avoid over-optimization and improves topical relevance.

2. External Linking Strategy

Link to Authoritative and Relevant Sources:When referencing facts, data, or industry insights, link to high-quality, trustworthy domains. It improves credibility and signals relevance to search engines.

Open External Links in a New Tab: To keep users on your site, consider setting external links to open in a new browser tab. This way, readers can explore the external source without leaving your page.

Be Mindful of Quantity and Placement:Don’t overload your content with outbound links. Use them only when they enhance the user’s understanding or provide genuine value.

Social Sharing & PR: Share your content strategically to attract backlinks. PR outreach, social media, and guest content can all help build your external link profile organically.
