Internal linking is often underestimated, but in fact it is one of the pillars of website positioning.
In reality, faulty internal linking can squander the SEO potential of even the best content. Properly planned internal link building, on the other hand, is one of the cheapest and most effective ways to boost your rankings and strengthen topical authority.
What mistakes should you avoid when internal linking on your website? Below are some of the most common… and most damaging.
Chaos instead of website structure
The first and most fundamental mistake is a lack of well-thought-out content architecture. It sounds trivial, but you can't treat a website as a collection of separate subpages.
(The rest of the article can be found below the form)
Articles and subpages are created "to fit keywords," but they are not connected in any way by a logical network of links. In practice, this means isolated, poorly linked texts that can only be accessed through the website's search engine or, perhaps, the blog's pagination.
A crawler who lands on such a subpage does not see the thematic context around it, so it is more difficult to assign the right phrases and understand that a given section of the website covers the topic exhaustively.
Correct internal link building starts with planning the tree: main sections, pillar pages, supporting content, and only then adding links that reflect this structure.
On many websites, you'll find several or a dozen articles on very similar topics, which de facto take on a life of their own. Each one has links to categories, perhaps to the home page, but there's no dense network of connections between them. This is a waste of potential.
From an algorithmic perspective, such a scattered set of documents doesn't build a strong signal of topical authority. Proper internal link building ties content into topical clusters: there's a pillar page that broadly encompasses a topic, supporting articles, and all these resources link to each other according to a clear logic, strengthening the entire cluster.
Random and navigational only linking
The second common SEO mistake is relying solely on menus, footers, and sidebars. These links are essential, but from an SEO perspective, they have limited contextual value. After all, they're identical across hundreds of pages, so they don't tell a story about a specific topic.
Equally dangerous is random linking: adding links where they "look nice," without any thematic relevance. This leads users to pages that don't expand on the ideas in the paragraph, increasing bounce rates and reducing the user's time on the page.
Correct internal linking should lead the reader along a "logical path" – from general to specific, from problem to solution, from definition to case study.
Unlinked key pages
Another mistake is leaving key pages with virtually no internal support. This often applies to offers, e-commerce categories, or lead-generating landing pages. If the only way to access such a subpage is through a menu or a single blog link, it doesn't seem like a priority from an algorithm perspective.
This is how orphaned or "semi-orphan" pages emerge – theoretically accessible, but practically ignored by search engines and users. Proper internal link building means that the most important addresses receive the most high-quality links: from thematically related articles, from other sections of the website, and from extensive category descriptions.
Anchors: empty, repetitive, cannibalizing
One of the most underrated areas is anchor text. Common mistakes include using empty anchor text like "here," "check," "read more," and mechanically repeating the same exact match on multiple pages.
In the first case, you deprive the crawler of a semantic clue – the link is there, but it doesn't convey any information. In the second, you create the perfect environment for cannibalization: multiple URLs compete for the same phrase because they're all linked with identical anchor text.
In a correct model, anchors are descriptive, diverse, and naturally embedded in the sentence, often based on long-tail terms and synonyms. A given topic has its own set of anchors, not a single, rigid template.
Excessive links and signal blurring
Another common mistake is over-crowding links on a single page. From a user experience perspective, the user is presented with a wall of blue text fragments, making it difficult to distinguish important elements from the "noise."
From an SEO perspective, the signal is dispersed: the equity is spread across dozens of addresses, and it becomes harder for the crawler to determine which ones are truly relevant.
Correct internal linking focuses on selection: fewer, but more accurately chosen links, placed in places where the user actually needs the next step in the path.
Internal links marked nofollow
Internal linking should use dofollow links by default.
It happens that the automation imposed on the CMS marks internal links as nofollow by default, which noticeably sabotages the entire internal linking - after all, we want to show the bot more subpages, not close the door to it.
The exceptions where nofollow comes into play are usually login, registration, or the customer panel, but even then it is a good idea to think it through carefully.
Technical errors
The final group of errors is technical. 301 redirects in link paths, broken links leading to 404 errors, and content buried too deep that requires four or five clicks – all of these things hinder crawling and reduce the chances of good visibility.
It is also common to find pages that have no outgoing internal links, making them dead ends.
Correct internal link building assumes the shallowest possible structure (key pages within a maximum of three clicks), regular cleaning of 404 errors and shortening redirection chains.

FAQs about internal linking errors
Internal linking serves two key purposes. First, it provides a roadmap for crawlers (Googlebots)—allowing them to efficiently navigate your site, discover new subpages, and understand the relationships between them. Second, it distributes link juice (SEO power) across the site. By properly targeting your links, you transfer power to the most important subpages (e.g., sales categories or key services), which directly improves their ranking in search results.
Orphan pages are subpages that lack a single internal link from the rest of your website. While they may physically exist on the server and be listed in your sitemap (sitemap.xml), they are extremely difficult for Google robots to find and rarely visited. This means you lose the sales and branding potential of the content hidden within.
The most common sins of webmasters and website owners include:
- Linking to broken pages (404 errors): Wastes crawl budget and irritates users.
- Using inactive (dead) links: For example, leaving broken links in graphics or menus.
- Too much link density: Putting dozens of links in a single paragraph of text, which looks unnatural (so-called keyword stuffing) and dilutes the power conveyed by a single link.
- Improper use of the rel=”nofollow” attribute: Blocking your own subpages from robots at the internal linking level, which is usually a mistake (with specific exceptions, such as the login subpage).
Anchor text is the clickable content of a link. The biggest and most common mistake is using generic phrases like "click here," "see more," or "in this article." These phrases convey nothing to either the user or the AI algorithms. A valid internal link should include a keyword and clearly describe what the target address contains, e.g., "Read our guide on [e-commerce SEO]."
Click depth is the number of mouse clicks required to reach a specific subpage from the home page. In SEO, the 3-click rule applies. If a user or Google crawler needs to click more than three times to reach an important product or article, it indicates that the page structure is too complex. Subpages buried too deep are less likely to be indexed and have significantly lower ranking power.
A silo (topic) structure involves logically grouping related content and linking it primarily within the same area ("silo"). For example, if your food blog has a "Pizza Recipes" section, articles in that category should link extensively to each other and to the main category page. However, they shouldn't randomly link to articles about desserts. This helps search engines and generative AI engines recognize your site as a specialized authority in a given field.
Summary
The above article covers the following topics:
- The process of internal linking is a key, yet often neglected, element of an SEO strategy that determines the effectiveness of content and a website's search engine ranking.
- Correct internal linking should be based on well-thought-out architecture and the creation of thematic clusters that combine isolated content into a logical structure that supports the website's positioning.
- Navigational and random linking alone is a mistake, because effective SEO requires building logical thematic paths within the content that provide the user and search engine robots with the appropriate context.
- It is a mistake to leave key pages unsupported, so proper link building should direct the most quality links to the most important offer and sales subpages.
- Avoid empty and repetitive anchor texts in favor of descriptive, varied anchor texts that provide search engine crawlers with semantic information and prevent keyword cannibalization.
- Excessive link density disperses the SEO signal and makes navigation difficult, so effective internal linking is based on the selection of relevant links that actually support the user's path.
- Using the nofollow attribute in internal linking is a mistake because it blocks robots from accessing subpages that should be indexed and supported by the dofollow attribute by default.
- Technical errors such as broken 404 links, too deep a click structure, or unnecessary redirects effectively hinder the indexing of a website and weaken its visibility in search engines.
