Internal Linking Explained
Internal linking means connecting the pages of a single site to one another through links placed within the content, with descriptive link text, to help Google understand the relative importance of each page and guide visitors toward relevant complementary content. It's an SEO lever entirely under the site's control, unlike external links.
Why internal links matter for SEO
Every link a page receives, whether from another site or another page on the same site, is read by Google as a signal of importance. A page linked from many other places on the site is generally seen as more central than an isolated page with no incoming links at all.
Beyond that signal, internal linking concretely helps Google's crawlers explore the site, since they discover new pages by following existing links. A page that's published but never linked from any other page on the site can take a long time to be discovered, or may never be discovered at all.
The effect on visitor experience
Internal linking doesn't only serve Google: it also guides visitors toward complementary content that answers questions related to their initial search. An article about bathroom renovation that naturally links to a dedicated page for a related plumbing service extends the visit and brings the visitor closer to making contact.
This extra time spent on the site, along with a lower bounce rate (leaving immediately without taking any other action), are indirect signals that favor SEO, on top of their direct commercial value.
Building logical linking, not mechanical linking
The most common mistake is adding links systematically and mechanically, with no real value for the reader, purely to multiply the number of internal links. This kind of artificial linking is easy to spot and brings neither value to the visitor nor a genuinely positive signal to Google.
Effective linking starts from the content itself: whenever a topic covered in detail elsewhere on the site is mentioned, a contextual link to that page naturally deepens the reading experience. This approach requires knowing the site's full set of pages in order to identify the relevant connections between them.
The role of link text (the anchor)
The clickable text of a link, called the anchor, gives an indication of the destination page's content, both to the visitor and to Google. A descriptive anchor such as "our guide to choosing SEO keywords" is far more useful than a vague anchor like "click here" or "learn more", which provides no information about what follows.
Slightly varying the anchors pointing to the same page, while remaining descriptive, avoids mechanical repetition while keeping the link clear for the reader.
Pillar pages, the heart of internal linking
On a site with several articles or pages covering the same broad topic, a more comprehensive, general pillar page can centralize links to all the more specific related pages, which in turn link back to that pillar page. This hub-and-spoke structure strengthens the pillar page's authority while helping Google understand the hierarchy between general and detailed content.
Internal linking versus external linking (backlinks)
Internal linking and external links (backlinks received from other sites) play a complementary but distinct role in SEO. External links are harder to obtain because they depend on the goodwill of other site publishers, while internal linking remains entirely in the hands of the site's own publisher, without depending on any third party.
This difference explains why internal linking deserves priority attention, especially for a recent site that hasn't yet had time to accumulate natural external links: it's the fastest lever to activate and adjust, with no waiting period and no negotiation with other parties.
Balancing links between old and new pages
A common trap is linking newly published pages only to each other, while forgetting to create links from the site's older pages toward this new content. Older pages, often already better ranked and receiving more traffic, pass on some of their authority to the pages they link to: ignoring them deprives new pages of valuable support for their own progress.
Conversely, periodically revisiting older pages to add links to more recent, relevant content keeps the linking structure alive, rather than frozen at the moment each page was created and never touched again.
Detecting orphan pages
An orphan page is a page that exists on the site but that no other internal link points to, making it hard to discover for both Google and visitors. These orphan pages often appear after a menu reorganization, a link removed during a partial redesign, or simply an oversight when publishing a new page.
A regular audit of internal linking, using tools that map the links between a site's pages, makes it possible to spot these isolated pages and add incoming links to them before they lose visibility entirely for lack of connection to the rest of the site.
Links in menus, footers, and conversion pages
Beyond contextual links within the body text, the main menu, the footer, and the calls to action present on every page also contribute to internal linking. A link to the contact or quote page consistently present on service pages, for example, naturally guides an interested visitor toward the next step, while also reinforcing the importance of that conversion page in Google's eyes.
Steps to build effective internal linking
- List all the site's pages along with their main topic.
- Identify the natural, relevant connections between these pages.
- Add contextual links within the content, wherever they bring real value.
- Write descriptive anchors rather than generic ones for each link.
- Identify or create pillar pages for the site's major topics.
- Regularly check that no important page is left without an incoming link.
What to remember
- Internal linking connects a site's pages to one another and remains entirely under the publisher's control.
- A well-placed internal link serves both Google's crawling and the visitor's experience.
- Mechanical, artificial linking brings little value, unlike genuinely relevant contextual links.
- A link's anchor should describe the destination content rather than use a vague phrase.
- Pillar pages centralize links to a set of more specific content on the same broad topic.
- Every published page should stay linked from at least one other page on the site to be properly discovered.
Conclusion
Internal linking requires few technical resources but a good understanding of your own content as a whole to create genuinely useful connections. It's one of the rare SEO levers that's fully controllable without depending on external factors.

Frequently asked questions
›What is the difference between internal linking and external links?
Internal linking connects the pages of the same site to one another. External links, or backlinks, come from other sites pointing to yours. Both count for SEO, but internal linking is entirely under your control, unlike external links.
›How many internal links does a page need?
There is no ideal fixed number. What matters is that every link added has real value for the reader and points to a page that is genuinely relevant to the content, rather than multiplying links without logic just to add more of them.
›Does the link text (anchor) matter?
Yes, a descriptive anchor that reflects the topic of the destination page ('see our guide on X') helps Google understand what the target content is about, unlike a vague anchor like 'click here', which gives no information about the destination.
›Does internal linking work for a small five-page site?
Yes, even at a small scale. Logically linking the contact page from the service pages, or the homepage from every page, is still useful. The effect is simply more limited than on a site with a full blog offering more opportunities for contextual links.
