Internal linking is one of the foundations of effective website optimization for search engines.
Through a strategic network of hyperlinks within a single domain, it allows not only for Google's algorithms to better understand the structure of the site, but also to improve the user experience and distribute the authority of the pages.
In the era of advanced AI models, such as those used in generative search, well-planned content connections become crucial to building topical authority.
But let's start from the very beginning, with the definition.
(The rest of the article can be found below the form)
What is internal linking?
Internal linking involves links pointing from one page to another within the same domain.
Unlike external links, which point to external sites, internal links create a navigation map that makes it easier for both users and crawlers to discover content. For example, in HTML, such a link takes the form:
<a href="/podstrona">Opisowy tekst kotwicy</a>
– where the anchor text provides semantic context.
Technical structure of internal linking – relative and absolute paths
It is worth mentioning that in terms of technical structure, we can distinguish two types of internal links – let’s assume that we want to link internally to a subpage at: verseo.pl/kontakt.
We can use the so-called relative path , i.e. include in the link only the fragment of the subpage address that comes after the slash ending the main domain:
<a href="/kontakt">Skontaktuj się z nami</a>
We can also use an absolute path , i.e. the full address:
<a href="https://verseo.pl/kontakt">Skontaktuj się z nami</a>
Which technique is better? There's no concrete data confirming the SEO advantage of one or the other – so you can use whichever method is most convenient for you.
Types of internal links
We can simplify into three main categories:
- navigation links (menu, breadcrumbs),
- contextual (in the content of articles),
- footer/sidebar (for key pages such as contact or regulations).
Navigational links define the hierarchy, contextual links deepen the topic, and auxiliary links provide universal access. Crawlers like Googlebot treat these links as priority paths, which speeds indexing and understanding the relationships between pages.
Navigation link - example from our website
Scroll up one floor and look at the top menu of verseo.pl – all these links take you to separate subpages related to the offer or other information about our agency.

Breadcrumbs – an example from our website
These internal links demonstrate the hierarchy—that is, this particular store SEO subpage is part of a broader SEO category , which in turn is part of an offer that belongs to the main page. You can jump to any of these points using breadcrumb links.

Contextual link - example from our website
Below is a screenshot from another article on our blog. The link in the content redirects to a subpage within the verseo.pl domain, where you can schedule a free SEO audit of your website.

Benefits of Internal Linking for SEO
One of the main advantages is improved indexing.
Googlebot and other search engine crawlers follow internal links, discovering new pages faster and more efficiently, which minimizes the risk of stranded content (i.e., content that exists and is published but cannot be easily accessed).
Crawlers therefore gain insight into the structure of the site and can thus obtain more complete data for the algorithm.
Benefits of internal linking for the user
The user perspective should also be considered. Internal linking is a crucial element of a website's user experience. Improving navigation directly leads to longer sessions and lower bounce rates, which signals the value of the content to search engines.
Furthermore, contextual links reinforce topical authority by creating content clusters where related articles support each other. This is particularly valuable in GEO ( AI SEO ). As a result, increased views and engagement translate into better ranking signals.
In this context, internal linking is crucial, for example, for e-commerce content. A blog post describing various aspects related to a given product category, such as a how-to article on "Which drone should you choose?" or "What to look for when choosing a laptop?", can include links to individual products, providing users with an immediate and—very importantly—naturally embedded link to where they can purchase the product.
Another example? Content portals that base their business model on creating articles—take film review sites as an example. An article about a new film by a specific director, with naturally woven links to articles about previous productions by the actors featured, allows the user to deepen their knowledge on a given topic, and the portal retains the user for longer.
Good internal linking practices
Internal linking is simply placing links between your pages on the same website – like doors and hallways connecting rooms in a house.
Imagine you're building a website about gym exercises: you add a link to a workout plan and descriptions of other exercises to an article about weighted squats. This helps Google search engines better understand your content and makes it easier for readers to discover more.
Make sure your anchor texts are friendly
The text on the link – the so-called anchor – is the visible link text that you see and click on the page – e.g. in the code:
<a href="/seo-poradnik">sprawdź przewodnik po SEO</a>
– the anchor is "check out the SEO guide." Avoid anchors like "click!" without more context.
IMPORTANT! Don't confuse the anchor with the title. The title attribute is a separate thing: a tooltip that appears on mouseover, e.g.:
<a href="/seo" title="Pełny poradnik dla początkujących">SEO</a>
The title attribute helps with accessibility (for screen readers), but it doesn't impact SEO as much as an anchor, which tells Google (and the user) what the target page is about.
Highlight links, but don't overdo it
You can use bold or italics to draw the eye and make it more clickable, but don't overdo it with excessive exposure. Or with the number – a maximum of 3–5 links per 1000 words is generally recommended.
Plan strategically
When starting your strategy, identify key pages, so-called pillar pages , and link them to supporting content. Think of the pillar page as a large guide, e.g., "Everything about SEO for beginners"—this is your main topic. From there, link to smaller articles, or "spokes," e.g., "How to write good content?" Anchor? Instead of "click," write "check out my guide to writing SEO content." From the spoke, you need to provide a way to return to the pillar: "Return to the full guide."
For example, on a blog about smartphones, the pillar "Top models 2026" links to "iPhone vs Android", and the latter links back – like a carousel that reinforces the whole.
Control
Check the "Links" section of Google Search Console (a free tool from Google)—it shows what's popular. If your "About Us" page has a lot of links, add a link to "Case Studies" there. Look for "orphan" pages—pages without links—and link them to categories.
Use breadcrumbs
Always think about the user: would I click? So add clickable breadcrumbs, like:
- Home > Blog > Post Category -> Post
- Home > Product Category -> Product
Don't use abbreviations
Don't use bots for mass linking - it can cause chaos and a potential penalty from Google.

FAQs about internal linking
This is a deliberate and strategic network of hyperlinks between different pages within the same domain. It is one of the absolute foundations of technical and content SEO, helping to structure the entire website's architecture.
A properly planned link structure performs three key functions:
- Helps Google robots (crawlers) discover, understand, and index new content faster.
- It transfers so-called ranking power (link juice) from the strongest pages (e.g. the home page) to weaker or newer subpages.
- It makes navigation easier for users, which increases their time spent on your site and reduces the bounce rate.
Use descriptive and varied anchor texts that naturally inform users and algorithms about what's behind the link (e.g., "check out the meta tag optimization guide"). Avoid empty, unnatural anchor texts like "click here" or "more."
This is called topic clustering. It involves creating a very comprehensive main page (pillar) that covers a given topic comprehensively, around which shorter, detailed articles (so-called satellites) are grouped. These articles link both to the pillar page and to each other, building significant topical authority in the eyes of search engines.
The most harmful practices include:
- Creating "orphan pages" (subpages to which no links lead).
- Applying the nofollow attribute to links on your own domain (this blocks the flow of ranking power).
- Excessive crowding of links in one text, which dilutes the SEO signal.
- Linking with the same anchors to different subpages, which may cause keyword cannibalization.
- Leaving broken links that return a 404 error.
