7 Internal Link Building Mistakes That Hurt Your SEO

Internal linking is one of those SEO tasks that can feel simple enough to run on autopilot. It is often the last thing we do when working on a piece of content, when we already see the end of our content creation process.

A typical writer spends days researching an article, getting all the data ready, outlining, writing, and adding external links and images. Speeding through the last, internal linking part seems a trivial thing to do.

That’s an unfortunate mistake. Failing to maximize your internal links SEO value creates a self-inflicted handicap that hurts your rankings.

In this post, we’ll look at seven internal linking mistakes that seem harmless but can have lasting SEO consequences. Fix them today to strengthen your entire site structure.

Why internal link building matters more than you think

A recent study conducted by Ahrefs shows that 66.2% of websites have pages supported by only a single incoming internal link. Furthermore, the same research revealed that 62.7% of websites contain internal links pointing to redirects.

For a tired copywriter about to finish their content piece, such a combination of mistakes may not seem unusual. But from an SEO professional perspective, that same combination of a single link plus a bunch of redirects signals a major ranking issue.

That lonely incoming internal link is perhaps the main concern, as it creates a highly fragile path for search engines. If it breaks or moves, the target page gets marooned.

Ahrefs openly describes internal links as an underused SEO lever.

A strong internal linking structure helps in three fundamental ways:

• It connects related pages;
• Establishes relationships between topics;
• Makes the hierarchy of your content clearer.

Search engines can use those connections to discover pages, understand their context, and determine which parts of your site deserve more attention.

And the interesting part is that internal links are entirely within your control. Unlike external links, you don’t need to conduct complex link-building campaigns and spend money, hoping that site owners will eventually choose to connect to your pages.

The decision on which pages should support each other on your website is entirely yours.

A well-thought-out, organized internal linking structure is good for SEO and, more recently, also for GEO (Generative Engine Optimization), as AI-powered search is increasingly about understanding relationships between concepts. Your internal links can reinforce those relationships by connecting supporting content with broader topic pages, related entities, and deeper explanations.

As a result, you form a well-connected content cluster that gives search engines — and AI-driven search systems — more context about how your content fits together.

On a broader, systemic level, a sound internal linking strategy has several SEO benefits for your site:

• Crawl budget preservation: Fully functional internal links prevent search bots from getting stuck in redirect loops.
• PageRank distribution: Links distribute authority across your entire website, from the key landing pages to deep pages on your blog and support sections.
• Clear site architecture: Grouping related content into clear clusters helps search engines understand your expertise.
• Better user retention: Contextual links encourage visitors to read multiple articles before leaving.

Apparently, there is a clear UX benefit too. Not only search bots, but also real users can better navigate your website and discover more content, provided you have allocated your internal links deliberately and wisely.

Despite these strong benefits, the value of internal linking often gets overlooked. Because it’s always within our immediate reach and power, we tend to set it aside and do (or forget to do) it at the very last moment. The quality of internal links is what suffers the most.

This brings us back to the purpose of the current article — to reveal seven key internal link building mistakes and offer best practices for avoiding them.

7 internal link building mistakes to avoid

Our list is organized to show a gradual progression in linking mistakes.

The first mistakes are more about individual linking decisions. From the middle to the end, the mistakes start to describe broader problems with your site’s internal linking structure and strategy.

We’ll open with anchor text and link relevance, then look at how link volume and equity distribution can affect your site. The last mistake in our progression is the one that often gets overlooked: treating internal linking as a one-time task.

1. Using generic anchor text

What does this mistake look like?

You’ve probably seen it hundreds of times: click here, read more, learn more, this article, or simply here. The simplicity of these links may be mistaken for effectiveness. Yes, they work, they’re crawlable, and readers can click them.

The problem is that the anchor text tells readers (and search engines) very little or nothing at all about the place where the link points.

The overly simple anchor text in these generic links is non-descriptive.

Now compare it with the ideal anchor text for internal links:

• Google recommends using anchor text that is relevant to the destination page, descriptive, and reasonably concise (two to three words).
• Ahrefs makes a similar point: descriptive link text gives both users and search engines more context about the linked page.

Source: Moz

For comparison, consider a sentence like:

For more information about improving your customer engagement, click here.

You can expect just about anything around the corner. This generic link could lead to a customer support guide, a retention policy, or a technical guide on how to fix major website issues and improve user experience. Now compare it with:

For a closer look at your site’s technical issues, see our technical SEO audit guide.

The second version gives a clear preview of what to expect when someone clicks the link.

Why is it a problem?

Generic anchors harm navigation for users. When users cannot clearly see where they’re heading, there won’t be a clear division between those motivated and engaged and those who don’t want to read any additional information.

However, the biggest problem that generic anchor texts create is their wasted SEO context. Instead of helping Google and other search engines understand the linked page, they waste the crawl budget and give little useful info.

Additionally, vague anchor texts:

• Hide opportunities to reinforce relationships between related topics.
• Make large internal linking structures harder to understand at a glance.

There is also a subtle motivation problem: engaged users seeking more information often get frustrated by the irrelevant content that they find behind generic links. Or the content is not what they expect to see, as vague anchor descriptions often create false expectations.

How to fix it

Start by reviewing your most common internal anchors. Look for vague phrases such as click here, read more, learn more, and this guide. Then fix all or most of them by changing the vague anchor wording into something more useful for readers.

You don’t need to re-read all your website’s content manually. Use the search function on your website, in your blog, or the general Google search that lets you find a specific phrase on a particular website (site:Yourwebsite.com/ search term).

It’s not necessary to cram a target keyword into every anchor, either. A good anchor should fit the sentence first and provide useful context second. In many cases, a natural phrase in internal linking such as technical SEO audit, internal linking guidebook, or user feedback manual will do the job perfectly.

2. Over-optimizing exact-match anchors

What does this mistake look like?

Over-optimizing exact-match anchors means repeatedly using the same keyword-rich phrase when linking to a particular internal page.

For example, suppose a site has a landing page targeting AI answer engine optimization. If ten articles on this website use the same anchor text to link to that landing page (e.g., enterprise SEO services), this signals to search engines a highly repetitive, over-optimized anchor text.

In real life, writers often edit their texts at the very end to insert links. Unfortunately, more often than not, they change natural sentences with artificial anchor texts. And they do it in multiple places in the same article. The anchor text that cleanly describes the destination gets replaced with keyword-rich, exact-match anchors.

A quick example

Imagine you have a page targeting SEO audit services.

Now look at three internal links pointing to that page:

Before redesigning your website, consider professionalSEO audit services.

OurSEO audit servicescan help uncover technical issues.

Learn more aboutSEO audit servicesbefore planning your next SEO campaign.

All three links are relevant. But together, they look overly deliberate because the exact same anchor is repeated every time.

A more natural version could be:

Before redesigning your website, consider a thoroughSEO audit.

A detailedtechnical website reviewcan help uncover hidden issues.

Why is it a problem?

There are two sides of the problem here. One is human, and another is machine or SEO.

The human side of the problem is when an over-optimized anchor text becomes noticeable to human readers. They see the same anchor text with the same keywords over several pages and articles. The obvious reaction is diminishing trust, more users who leave, and fewer pages that get read.

The technical, or SEO part of the problem is different. Google explicitly says internal-link anchor text helps both users and Google make sense of a site. But the problem with over-optimized anchor text is that it doesn’t.

If 50 internal links all point to the same page with exactly the same anchor, Google repeatedly receives essentially the same contextual signal.

Several internal links SEO problems emerge at once:

• You lose contextual variety. A page may be relevant to several related concepts, but identical anchors keep describing it through only one phrase.
• You oversimplify the page's topical relationship with the rest of the site. In a real-life scenario, different pages will have slightly different angles when they connect with the destination page. By using the same anchor text over and over, you make that relationship unnaturally simple and artificial.
• Forced anchor optimization may start resembling keyword stuffing. You may not immediately notice when that happens, but when it does, keyword stuffing gets explicitly penalized by Google.

Source: Searchenginejournal

As a result, the internal linking signal that should clarify relationships between pages becomes repetitive, narrow, or even ambiguous. You simply miss the opportunity to increase your website’s authority in the eyes of search engines.

How to fix it

Removing ALL exact-match anchors isn’t the best approach. Some of them might make good sense.

Start by checking all pages that lead to your key landing or central pages. Fix only those where the anchor text doesn’t quite fit the context.

Usually, when doing this exercise several days or weeks after you’ve created the original articles, the bad match between anchor and context will literally scream at you. It’s a known trick in writing to proofread your work the next day, when you’ll already have a fresh eye and mind.

Also check whether the same anchor text points to different URLs across your site. If several pages are repeatedly linked with the same keyword, decide which page is actually the best destination for that topic. Then make the other links more specific where necessary.

Pro tip: For large, content-heavy websites, doing this exercise manually will be a cognitive nightmare. You can use specialized SEO crawling tools (e.g., Semrush Site Audit, Screaming Frog, Sitebulb, Ahrefs Site Audit, and others), which can export all internal links on your site together with source URLs, destination URLs, and anchor text. Inside the tool, you can sort the data by destination and see all anchor text repetitions, if it’s the case.

For instance, here is a quick snapshot of what a Semrush Site Audit tool can do to help you improve internal linking:

3. Linking to irrelevant pages

What does this mistake look like?

Not every internal link is a useful internal link.

You can have a perfectly contextually relevant link in a text, use a descriptive anchor text, but it won’t do any good for your website’s SEO. Why? Because your destination page has little to do with the context around the link.

This mistake is more common than you think. And it mostly emerges when you try to forcefully and hastily place as many internal links as possible, without reading the content carefully.

One common scenario is when a writer finishes an article, sees that it needs three or four internal links, and starts looking for pages to add. This exercise turns out to be a numbers game, where the quantity of links is more important than their quality.

For example, imagine an article about reducing customer acquisition costs. It mentions social media advertising in one paragraph. The writer sees an opportunity and links the words social media to a general guide about creating Instagram posts.

Technically, there is a connection. Both pages talk about social media.

But that connection is not what you want, as it’s very weak.

Someone reading about customer acquisition costs is much more likely to benefit from a page about paid social advertising, advertising ROI, conversion rates, or lowering acquisition costs.

Why is it a problem?

Internal links help search engines understand how different pages on your website relate to each other.

When relevant pages regularly link to one another, they create a logical structure. All the interlinked pages revolve around closely related topics.

But irrelevant links add noise or even break this perfect structure.

If the same technical SEO guide suddenly links to loosely related pages about marketing theories, advertising, or web design principles, search bots start to receive incoherent information about the relationships between the pages on your site.

And there is another SEO interlinking issue: internal links distribute authority across your website.

By linking to a useful page, you channel the authority to the place where it’s most needed. But linking to an irrelevant page sends some of that value into nowhere. It’s a waste of value.

Besides, irrelevant internal links can also:

• Send users to content they didn’t expect to see.
• Increase the chance that visitors immediately return to the original page.
• Steal the attention from other important internal pages.

How to fix it

For the fix, we’d suggest asking one simple question every time you ponder over the quality of an internal link:

Would someone reading this particular paragraph genuinely benefit from opening that page?

If the answer is no, drop that link and look for other places where such a link would be genuinely useful.

Don’t choose internal links only because two pages contain the same keyword. Look at the topic, search intent, and context around the link.

Source: Moz

Other relevant questions to ask yourself may include:

• Does the destination page expand on the exact idea being discussed?
• Does the anchor text accurately describe what users will find upon following the link?
• Is there another page (article, blog post) on your site that provides much more useful additional information on that concept/idea/topic?

It’s often better to not place any links at all than to create a mess with unrelated or loosely related topics and concepts.

4. Creating too many internal links

What does this mistake look like?

We have all read articles with too many links. Perhaps we skimmed through them, as reading a text with a link in every paragraph doesn’t look pretty. We quickly lose trust.

With too many internal links, the situation is the same. They look forced, abundant, and make texts appear overly commercial, as if someone is competing for your attention and wants to sell you something.

Why is it a problem?

Links give search engines pathways to follow, sending important signals about how content is interconnected on your website. They help distribute authority and help search engines understand concepts and entities.

However, more internal links don’t translate into more SEO benefits. They can actually cause harm. Besides apparent user experience damage (when a reader stops trusting a text with too many links, or their attention is diluted), too many internal links can have the following negative consequences for internal links SEO:

• Make the hierarchy of important and secondary pages less clear.
• Send link equity to pages that don't really need it.
• Create dozens of competing paths instead of directing users toward the most useful next steps.
• Make anchor text and surrounding content harder to read.
• Steal crawl budget from search crawlers when thousands of duplicate paths lead to the same destinations.

How to fix it

There is no clear threshold after which links start to cause more harm than they do good, but one useful principle in their saturation is modesty.

A 7,000-page research paper may contain 30 internal links, and that’s OK. But a 700-page article must proportionally have 3, i.e., ten times fewer.

When placing links internally, review every one of them and question what they actually do for the page. A good link should help the readers explore your content and discover closely-related content. It should also connect related pages together.

If a link doesn’t do any of the above two things, consider not using it. You don’t need a link that doesn’t provide real value.

It’s similar to a spice in a food, or jewelry on a dress. In small amounts, it tastes good and looks great; it adds value. But too much destroys all the benefits and produces an opposite effect.

When reviewing large websites with hundreds of thousands of pages, you cannot effectively fix every interconnection manually. If that’s the case, use a crawler such as Screaming Frog or Sitebulb to identify pages with unusually high numbers of outgoing internal links. But treat those pages as candidates for review, not as pages that automatically need fixing.

Remove only the ones that don’t earn their place.

5. Linking to pages that shouldn't receive SEO value

What does this mistake look like?

Not all pages are worth linking to. Accordingly, they shouldn’t receive SEO value.

Think of the pages that are created specifically to attract organic traffic. And others that exist simply because users need them to use the website.

Examples may include:

• Login and account pages.
• Shopping carts and checkout pages.
• Thank-you and confirmation pages.
• Certain filtered or faceted navigation URLs.
• Duplicate or near-duplicate pages

Besides, promotional or campaign pages quite naturally get old. You don’t want to get rid of them as they are still useful, but you don’t see a great sense in updating them either, as the product or service they describe doesn’t need to be updated.

What you don’t want is to treat such pages with the same importance as your main website pages, your most important landing pages, and product pages. Unfortunately, many SEOs often treat all pages on their sites similarly. And that is a problem.

Why is it a problem?

By linking to them with the same rigor as to your most important pages, you waste your time and efforts and create unnecessary noise, diluted SEO value, and authority concentration.

For example, imagine that an ecommerce category page links to 50 useful product and subcategory pages. But it also generates another 100 links to filter combinations with little unique content.

Search bots now have 150 paths to follow.

Some lead to valuable pages. Others lead to URLs such as:

/shoes?color=black&size=10&sort=price

There are several consequences for your internal links SEO:

• Internal PageRank gets distributed to unnecessary URLs.
• Search bots spend more time crawling duplicate, filtered, or otherwise low-value URLs.
• Large numbers of unnecessary URLs can make the site's architecture more complicated for search engines to process.

This diminishes the value of your most important pages, as they become relatively less prominent within your internal linkstructure.

How to fix it

Audit your website to clearly identify pages that matter to organic search and those that only have a functional purpose.

And a frequent mistake that SEOs often make at this stage is removing ALL links to login pages, navigational pages, checkout, and other similar ones. Users still need to find those pages.

You need to carefully evaluate and decide what should happen to each type of URL.

For example, if an old article has been replaced by a newer and better version, update your internal links to point directly to the new page. Don't keep sending users and search bots through an unnecessary redirect.

For faceted navigation, the solution may require more technical work.

Don't automatically make every possible filter combination crawlable. Leave only those filtered pages that have genuine search value.

The same principle applies to automated internal linking.

If a CMS, plugin, or website template generates hundreds of links, check where those links actually lead. A small template-level change can remove thousands of unnecessary connections across a large site.

And don't use nofollow as a universal solution. It is not a reliable way to “save” PageRank and redistribute it to your important pages. Consider removing the link altogether instead.

An equally bad scenario is when all or most of your links have the dofollow attribute.

Source: RankMath

The bottom line: Remove unnecessary internal links where they serve no important purpose. Keep functional links where users need them. The strongest internal linking paths should lead toward the content you actually want search engines to discover, understand, and prioritize.

6. Starving deep pages of link equity

What does this mistake look like?

Put simply, this mistake is about the lack of links to some key pages. The problem most often manifests itself on content-heavy sites, when distributing link equity equally across pages becomes difficult.

Imagine the following path:

Homepage → Blog → SEO → Technical SEO → Guides → Article

It may take four or five clicks to reach that final article from the homepage.

You may have an excellent article that targets an important keyword. But the only internal link pointing to it comes from an old category page three levels deep in your site structure. You simply wrote that article a long time ago and forgot about its existence, linking mostly newer articles.

Often, this problem is accompanied by a discrepancy: a newer article on the same topic may get plenty of internal links pointing to it, but your old article receives no links at all.

Why is it a problem?

These two pages in the example above are not getting the same internal support. It’s a shame, as together, they’d have made a perfect coverage of the topic.

The situation leads to some important pages getting starved of internal PageRank — Google’s original system for estimating the importance of a webpage.

This is what literally happens on your website: pages that receive links from other strong pages get a share of their internal PageRank. At the same time, pages with very few incoming links receive much less of it.

But the problem is not only in the PageRank distribution. Internal links also help search bots understand which pages you consider important and how those pages fit into the wider website structure.

Pages that are buried deep inside your internal linking structure are not crawled properly, which leads to poor discoverability. If search engines cannot discover some of your pages, the search ranking suffers.

Human readers also struggle to find your content. Click-through rate and depth are the most common SEO metrics that suffer.

How to fix it

You can solve this problem through several simple steps:

1. Make an audit of your website content and identify all the pages that you want to rank. The next step is to check if they receive enough internal links.

For a small website, this operation can be done manually. But for larger sites, the exercise demands automation and help from SEO tools. For instance, in Screaming Frog, you can crawl your site, select the URL, and look at its Unique Inlinks and the Inlinks tab. Ahrefs Site Audit and Site Explorer can provide similar information.

1. Check where those links come from. Make sure the pages you want to rank receive contextual links from closely related pages.
2. Also, you’d want to check the quality of anchor texts and the surrounding context. For example, if you want an article about technical SEO audits to rank, links from articles about crawling, indexing, XML sitemaps, and site architecture make logical sense.
3. Finally, review link depth. If the linking path is too long and complicated, consider shortening it.

7. Treating internal linking as a one-time task

What does this mistake look like?

Even if you fix all the above-mentioned mistakes, you might still run into trouble — a different kind — with time.

The thing is that your website doesn’t stay still. It changes and grows with your business or brand. You publish new guides. Add product and service pages. Update old content. Merge similar articles. Delete outdated pages. Create duplicate content and delete the one with less value. Change URLs and sometimes restructure entire sections of the website.

But the article or page with the six mistakes fixed remains unchanged. New topics or their extensions don’t connect with it. Neither does the article connect with the newly created pages.

The moral: internal linking is a continuous SEO process. You don’t do it once and for all. You should keep coming back to your old pages, rethink their connection logic with the new pages, and optimize internal links wherever possible.

Why is it a problem?

If you don’t treat internal linking as an ongoing exercise, the six problems you’ve already solved magically reappear again. It’s like maintaining a car, or renovating a house, or any physical object that degrades over time.

The new pages that you create miss relevant internal links that could pass link equity, provide additional crawl paths, and show search engines how the new content fits into your existing site structure.

Older links start to accumulate problems too.

For example, they may point to URLs that now redirect. Google can follow those redirects. Even worse, some old links may lead to deleted pages and return a 404 error. That’s a serious SEO issue, damaging your website’s search performance.

Over time, a neglected internal linking strategy can result in:

• Important new pages receiving fewer internal links than they should.
• Old pages continue to receive internal links even though they are no longer SEO priorities.
• Broken internal links.
• Unnecessary redirect chains.
• Orphan or poorly connected content.

The list can go on and on, as these seemingly minor SEO issues aggregate and grow like a snowball down a mountain.

How to fix it

The fix is obvious and straightforward. You should make internal linking an important part of your regular content maintenance.

No need to check every link on your website. A good maintenance routine, plus random, targeted checks, will suffice.

For example, whenever you publish a new page, don't only add links from it. Look for older relevant pages that could link to it as well.

Then, periodically review the rest of your internal links.

Look for:

• Broken links leading to 404 pages.
• Links pointing through unnecessary redirects.
• Important pages with very few incoming internal links.
• Orphan pages.
• Old URLs that have better or newer replacements.

The easiest part that can cover 80% of your interlinking needs is to work with your recently published content. The goal is to connect it properly with older pages. And as you open your older pages, you can simultaneously check random links there and fix any potential linking problems.

Conclusion

Internal link building is just as important a component of your SEO as any other part, be it keyword research, competitor analysis, or content analysis.

Today, we have shown why that is true by discussing some of the most common internal linking mistakes, analyzing their anatomy, and explaining how to build a solid internal link structure devoid of these mistakes.

The following three key takeaways should help you put all these recommendations into practice:

1. Internal linking is about quality and logic, not quantity. More links, more keywords in anchors, or more links to a priority page don't automatically mean better internal links SEO. The best links are the ones that naturally connect related pages, use meaningful anchors, and help readers explore a topic and search bots understand your website.
2. Your internal linking structure should reflect which pages actually matter. This one is about conscious internal linking, when you deliberately make certain pages stand out and distribute PageRank fairly.
3. Internal linking is a system you maintain, not a task you complete. Don’t do internal link building as a task or project. Rather, it’s your business or SEO process, or ongoing project that never ends. As you add more content and create new pages on your site, you should link them properly to your existing content logic.

Your entire link system should evolve with your site. If SEO rules and priorities change (e.g., you need to optimize for AI or generative engines), so should your internal links’ anchor text, keywords, and their frequency reflect these changes.

FAQ

What is an internal link?

An internal link is the kind of link that stays on your website and connects two or more pages together. When you click on an internal link, you get taken to another page on your website. Simple as that. These links help readers find related information and facilitate a better understanding of your website’s content by search engines.

What is the difference between backlinks and internal links?

Backlinks come from somebody else’s website. Internal links are the ones you create between your own pages. The first can bring authority into your site; the second helps spread that authority around and connect related content. And there is one obvious advantage with internal links: you decide where they go.

How many internal links should a page have?

There is no fixed or ideal number of internal links for a given page. Since pages differ by purpose and word count, the exact number of internal links will vary too. The only guiding principle is to rely on common sense and to genuinely try to help readers understand your content. One link per 3-4 paragraphs will be helpful, but a link in each paragraph might scare off readers by appearing too pushy or overly commercial.

How do I know which pages need more internal links?

If a page that you want to rank high in Google results currently sits deep inside your website’s structure, consider improving its visibility by adding more internal links. Also, look at where its existing links come from. A few good links from closely related pages can tell you much more than a large raw inlink count.

Do internal links help SEO rankings?

Yes, but they are not a ranking shortcut. Internal links help real users discover content on your site. They also help search engines to crawl your website, understand its content, and move PageRank through your pages. That kind of discoverability and user experience matter, but weak page content-wise won’t suddenly rank high in SERPs if you stuff it with ten internal links. Ranking via internal linking takes time.
