Internal linking might sound like just another SEO term, but it’s actually one of the most powerful tools you can use to boost your website’s performance. Think of internal links like bridges—guiding visitors (and search engines) from one page to another, creating a clear path through your content.
These links not only help your audience explore more of what you offer but also send signals to search engines about which pages are important. When done right, internal linking can improve user experience, keep visitors on your site longer, and increase your chances of ranking higher on search engines like Google.
In this guide, I’ll break down everything you need to know about internal linking—from the basics to advanced strategies—so you can build an SEO-friendly website that works for you!

What Are Internal and External Links?
Internal and external links play a critical role in guiding users through the web and helping search engines understand how content is related. Here’s how they differ:
Internal Links: These links connect one page of a website to another page within the same domain. For example, linking from your homepage to your services page.
External Links: Also very commonly known as backlinks, direct users from your website to another domain entirely. Think of it as referencing other valuable resources outside of your own site.
Internal Links vs. External Links
Internal Links build a structure within your website, helping search engines understand page hierarchy while keeping visitors engaged.
External Links add credibility by linking to other authoritative sources, which signals search engines that you’re providing valuable information.
Both internal and external links are essential for a well-rounded SEO strategy, but internal links give you more control over your content’s visibility and flow.
How to Find Internal Links to a Page
Locating internal links within your website ensures you know how different pages connect and if your important content is receiving enough link authority. Here are effective ways to find and analyze these links:
Manually Checking Pages: Go through key pages on your website and look for hyperlinks pointing to other internal pages. This gives a quick snapshot of how content connects.
Browser Search Function: Use CTRL + F (Windows) or Command + F (Mac) to search for specific internal links within your website’s HTML or text content.
Content Management Systems (CMS): Platforms like WordPress offer internal link suggestions when writing content, making it easier to cross-link relevant posts and pages.
Tools to Find Internal Links in Your Website
Save time by using dedicated tools to locate and analyze internal links across your site.
Google Search Console: In the "Links" report, you’ll find pages linked most often from your internal structure.
Screaming Frog: This SEO tool crawls your site and shows how all pages are interlinked, helping you identify gaps and new opportunities.
Ahrefs or Semrush: Both tools offer internal linking reports that reveal which pages link to each other and highlight orphaned pages (pages with no internal links).
Identifying Pages Linking to Other Pages
Knowing which pages are linking to others is essential for distributing link equity effectively and driving traffic to key pages.
Best Practices for Discovery:
Prioritize linking high-traffic pages to newer or underperforming ones to increase visibility.
Use contextual links within relevant content—links embedded in blogs, landing pages, or FAQs perform better than those in footers or sidebars.
Pro Tip: Avoid linking pages in a random manner. Make sure each link serves a purpose, whether it’s guiding users to related content or driving conversions through targeted calls to action.
