Internal Linking for SEO: The Complete Guide in 2024

Internal linking is essential to any website because it helps establish site architecture and spread the link juice. Simply speaking, internal linking refers to any links from one page of a domain, which is linked to another page within the same domain. It can be linking to categories or main site navigation, within articles to related content or the footer, etc.

Internal link building has several advantages as it helps build page authority, domain authority, usability, connections between web pages, user experience, and potentially your search engine rankings. This article aims to provide useful tips on why you should focus on your internal linking and how it can bring a plethora of SEO benefits to your website.

What Are Internal Links?

If your website is a bustling marketplace, interlinks are like signposts, directing visitors from one stall (or webpage) to another within your website. Internal links connect relevant content within your website, helping users navigate smoothly and discover hidden gems. These links also play a secret role, whispering to search engines about the importance of different pages on your site. By strategically using internal links, you can create a user-friendly website that ranks higher in search results.

On paper, they seem trivial and it looks like internal linking doesn’t bring significant results. But dig deep into the technicalities and you’ll find that relevant internal linking results in:

• Improved domain authority
• Better user navigation and experience
• Lower bounce rates
• Higher SERP rankings, and more.

Why Are Internal Links Important?

An internal link might seem like a simple website feature, but they pack a powerful punch. They’re not just about helping users find their way around your website; they’re a strategic tool that benefits both your visitors and your SEO efforts. Let’s delve into why internal links are so important:

Weaving A User-Friendly Web

Internal links act as a guide, connecting related content and allowing users to explore your website intuitively. They keep visitors engaged by offering them a clear path to discover deeper information or explore topics that pique their interest. This smooth navigation experience keeps users happy and encourages them to spend more time on your website, an important aspect for engagement metrics.

Building A Strong Information Architecture

Internal links act like bridges, creating a clear hierarchy and structure for your website. By strategically linking relevant pages together, you signal the importance and relationships between different pieces of content. This helps search engines like Google understand the overall theme and organization of your site, allowing them to crawl and index your content more effectively.

Spreading The SEO Power

Internal links are a way to distribute “link juice” – a search engine ranking factor. When you link to high-quality pages within your website, you’re essentially sharing that ranking power. This can help boost the authority and visibility of less prominent pages, potentially improving their ranking for relevant keywords. By strategically distributing link juice, you can ensure that all your valuable content has a chance to shine in search engine results.

Keep Visitors Engaged

Internal links can be a powerful tool for keeping visitors hooked. Let’s say you’re reading a blog post about healthy recipes. A well-placed internal link to a detailed article on how to make fresh homemade protein smoothies might entice the reader to delve deeper. This increases page views, alleviates bounce rate on your pages, and keeps users engaged with your website for longer periods of time. Ultimately, this engagement level tells search engines that people love your content, so they start showing your pages on top of SERPs more often.

Sculpting The Search Engine Journey

Search engines rely heavily on internal links to understand the context and flow of information on your website. By strategically linking related pages, you can guide search engines towards the content you deem most important. This can potentially improve your website’s ranking for relevant keywords by sending search engines the right signals about your content’s focus and value.

Building Topical Authority

Internal linking allows you to create thematic clusters within your website. Imagine a travel website with blog posts on various European destinations. Leveraging connections between these posts establishes them as related topics, telling search engines that the site is a complete European travel encyclopedia. With this kind of focused linking approach, the authority for particular keywords can be strengthened and this is likely to improve your ranks on search engine results pages.

Combating Orphaned Pages

Every page on your website deserves to be seen. Internal linking helps prevent orphaned pages – valuable content that sits isolated, unnoticed by search engines and users alike. Linking with a plan to these hidden gems can bring them into the fold, ensuring they get indexed and discovered.

Encouraging Fresh Content Discovery

Internal linking isn’t just about promoting older content. It’s also useful in sending traffic to your new content. This action introduces your newly built pages to users while they go through already established content that is successful and maintains that feel of newness and dynamism on the site. And fresh content discovery is just one side of the story. Due to the ability of passing the link juice, these internal links will uplift the authority of those fresh pages, expediting the ranking process on search engines.

Simplifying Website Navigation

For a good user experience, it is essential to have a website with clear and easy-to-understand navigation. A tricky, puzzle-like interface will be the last thing you want on your website, as it will drive the users away from your pages. Guiding users along the way through your website’s hierarchy, internal links act as breadcrumbs, making information search straightforward. This simplified navigation keeps users engaged and reduces frustration and the dreaded bounce rate (which can leave a dent on the user experience and put your site in the bad books on search engines).

Promoting Calls To Action

Internal links can be powerful tools for driving conversions. Let’s say there’s a blog post on healthy eating habits. By strategically linking to a page with meal plans or a recipe ebook, you’re gently nudging users towards a desired action. This targeted approach allows you to leverage your existing content to promote specific products or services.

Building Brand Consistency

A well-linked website fosters a sense of brand consistency. Connecting related content across different sections helps you reinforce your brand message and establish yourself as a thought leader within your industry. This cohesive brand experience builds trust and loyalty with your audience.

Improving Mobile Usability

User experience becomes even more important on smaller screens. Internal links can enhance mobile usability by making it easy for users to navigate your website with just a few taps. Ensure your internal links are visible enough, not looking spammy on mobile devices, easy to identify even in dark mode, etc. You can also employ tactics like A/B testing or heatmaps to check if your links are attracting the eyeballs they were supposed to on mobile devices.

Streamlining Website Updates

As your website grows, evolves, and scales, internal linking becomes even more vital. New content can be seamlessly integrated into existing webs of information, ensuring it gets discovered by search engines and users alike. This makes website updates and content expansion a breeze. It’s always better to have a linking roadmap or just a list of the few highly important pages you are prioritizing. Having such a list will remind you to add their URL on every important page, which will signal search engines about the significance of the page.

Advantages Of A Good Internal Linking

A well-crafted internal linking strategy can be your website’s secret weapon, boosting user experience, SEO performance, and overall engagement. Here’s why:

1. Internal Linking Improves User Experience

Finding the way through a website with poor internal link structure feels like getting lost in a maze with no clear path. Internal links pointing users towards relevant content act like helpful guides, keeping readers engaged and exploring.

• The User-Centric Approach: A well-linked blog post on a specific topic, for example, can connect to articles that delve deeper into related areas. Think of a post on home gardening. Links to articles on different vegetable varieties, DIY composting techniques, or essential gardening tools provide valuable resources for the reader. This creates a smooth sailing journey for users, allowing them to discover more without feeling lost.

• Reduced Bounce Rates, Increased Satisfaction: Strong internal linking encourages users to explore further, which translates to lower bounce rates (the percentage of visitors who leave after viewing only one page and not taking any action on it). Satisfied users are more likely to return in the future, fostering a loyal audience.

• A Clear Information Roadmap: You don’t want to leave your readers in the lurch after making them land on your website. Internal linking takes care of this and ensures your readers steer clear on the right pages without any friction. Linking to your own pages tells readers that you have more related content on the subject, so they can get in-depth information about the topic without reaching for a different site, just like how a YouTube creator adds the links in the “i” button or description for a video related to the current video.

2. Internal Link Helps Spread The Link Juice

Link juice is like a website’s currency – the more a page receives links from other high-authority pages within your site, the more valuable it becomes in the eyes of search engines. Internal linking helps distribute this link juice effectively.

• Boosting Page Authority: Carefully linking relevant pages together tells search engines which content deserves a higher ranking for specific keywords. This targeted flow on link juice strengthens the authority of individual pages within your website, which comes together to improve the entire domain authority.

• A Stronger Website Overall: Imagine a website where only the homepage receives the links. The rest of the content languishes in obscurity. Internal linking helps distribute link juice throughout your website, potentially boosting the ranking of all your pages and increasing overall website authority.
• Makes You A Credible Name In Your Niche: Internal links aren’t just for keeping your readers stuck to your website. If woven together strategically within the content, they have the potential to enhance your site’s credibility in the industry. Using correct internal links has a positive impact on your Domain Authority (DA). Higher domain authority helps you secure higher search engine rankings. Apart from search rankings, websites with higher domain authority are often looked at as valuable resources for information. You’d obviously prefer the email marketing tactics shared by Forbes rather than a random, shady website.

3. Internal Linking Boosts Page Views

Ever get sucked down a Wikipedia rabbit hole, clicking from link to link and learning a ton? That’s the magic of well-placed internal links. They pique user curiosity and encourage them to explore further, racking up page views.

• The Power Of Curiosity: Well-crafted & descriptive anchor text – the visible text of the link – acts as a teaser, enticing users to click. Think beyond generic phrases like “read more” and use descriptive keywords like “Download your copywriting guide” to accurately reflect the linked page’s content.

• More Content, More Value: With a well-linked website, users can easily find related content that expands their knowledge and keeps them engaged. This translates to more page views, a key metric for website success. But this does not mean that you can add links anywhere and everywhere just to keep them hopping from one page to another. The point is to find the right balance. More about it later in this article.
• Become A Search Engine Favorite: As discussed in the earlier point, internal links are an amazing tool for uplifting your website’s domain authority. In search engine’s eyes, higher domain authority means a trustworthy source. Bloggers often check domain authority before linking to a site, and high-authority websites often rank on the first pages (even for competitive terms). The verdict? Internal links amplify domain authority, and domain authority boosts rankings. So, if you are eyeing those number-one spots on SERPs, plan your internal links strategically.

4. Internal Linking Improves Time On Site

The longer users stay on your website, the more valuable they become. Internal linking plays a vital role in keeping visitors engaged, leading to increased time on site.

• Engaging Content Flow: Strategic internal linking encourages users to explore further, reading related articles, watching videos, or downloading resources, which creates a sense of continuous discovery, keeping them hooked and spending more time on your website.

• Building Brand Loyalty: Increased time on site benefits your SEO and allows you to establish yourself as an authority in your niche. Users who spend more time consuming your content are more likely to trust your expertise and brand, fostering loyalty.
• Increasing The Chances Of Conversions: Internal links make users stick to your site. And having long-lasting users isn’t just an aid for improving your vanity metrics. It can actually turn into tangible results. Users sticking to your content shows they love your content. When they love your content, they will also believe what you suggest or sell them. So, if you put a CTA at the end of your blog saying, “Get trendy web designing tips in your email,” they’re more likely to click on it and opt-in since they trust you. This is an indirect effect, but the right linking at the right place will surely lead you there.

5. Internal Linking Helps To Crawl And Indexing

Search engines rely on crawlers – automated programs that scan through websites to discover and index content. Internal links act as a roadmap for these search engine crawlers, making it easier for them to find and understand your website’s structure.

• Unveiling Hidden Treasures: Search engines might miss valuable content buried deep within your website if it’s not properly linked. Strategic internal linking ensures all your content gets discovered and indexed, improving your website’s visibility in search results.
• A Well-Oiled Machine: Internal links help search engines efficiently crawl and index your website, ensuring all your valuable content gets a chance to shine in search results. This comprehensive indexing can lead to higher website traffic and organic search growth.
• Outsmarting Competition: Conversions, lower bounce rates, better on-site engagement, higher domain authority. You are familiar with these amazing perks of well-planned internal linking. But the icing on the cake is that these elements play a huge part in keeping you ahead of your competition. There’s a continuous war going on in the digital ecosystem, and every contender is trying to outrank its competitors. In this cutthroat competition, having all best practice boxes checked can give you an edge over your competitors. Just use your internal links wisely, and your competition won’t be able to chase you.

How Many Internal Links Should Be On A Page?

Too few internal links leave users lost, while too many create a confusing labyrinth. So, how many internal links should grace a single webpage for optimal SEO and user experience?

There’s no magic number etched in the SEO stone. The ideal amount depends on several factors, like your page length, content type, and website structure. Let’s explore some helpful guidelines to find that sweet spot.

How Many Internal Links On A Page Is Good?

Internal links are bridges connecting different islands of information on your website. A well-linked page helps users move around your website seamlessly, discover relevant content, and, ultimately, stay engaged. Here’s why a healthy dose of internal links is beneficial:

• Improved User Experience: Strategic linking allows users to delve deeper into topics that pique their interest. Imagine reading a blog post about hiking essentials. Well-placed links to articles on specific gears or popular hiking trails keep users on the website, exploring related content. 

• Enhanced SEO: Internal links distribute “link juice” — a search engine ranking factor – throughout your website. By linking relevant pages together, you signal their importance to search engines, potentially boosting their ranking for targeted keywords.

• Stronger Website Architecture: Creating internal links builds a clear hierarchy, helping search engines understand your website’s structure and content organization.

How Many Internal Links Is Too Many?

While internal links are valuable, overdoing it can backfire. Here’s what happens when you go overboard:

• Information Overload: A cluttered page with too many links overwhelms users. They might not know where to focus, leading to frustration and a quick exit.

• Diluted Link Juice: Imagine a room full of people whispering secrets. The message gets lost. Similarly, with excessive internal links, the SEO value (link juice) gets diluted, weakening the impact on each individual page.

• Search Engine Confusion: Search engines might prioritize certain links on a page based on placement or prominence. Too many internal links can make it difficult for them to determine the most relevant ones.

Finding The Balance

So, how many links is “just right?” Here are some practical pointers:

• Focus On Relevance: Prioritize linking to content directly related to the current page’s topic. Don’t shoehorn irrelevant links just to hit a quota.
• Consider Length: Longer pages naturally lend themselves to more internal links. Aim for a balanced distribution – enough to guide users without overwhelming them. A good rule of thumb is 3-5 internal links for shorter pages and 5-7 for longer content-rich ones.
• Prioritize User Experience: Would you, as a user, find the link helpful and relevant? If not, leave it out.

How to Optimize Your Internal Linking?

But how do you build a strong internal linking structure that’s both SEO-friendly and user-centric? Here are a few factors to consider:

1. Segment And Focus

Before you start adding internal links randomly, take a step back and understand your website’s content architecture. Group similar topics together into thematic clusters. This could be product categories for an eCommerce store or different service offerings for a professional firm.

For example, on a travel website, a blog post on “Must see sights in Rome” could link to other articles on “Day trips from Rome” and “Hidden gems of Rome.” This focused linking strengthens the topical relevance of each page and helps search engines understand your website’s hierarchy.

2. Build Semantic Sillos

When you are writing new content, you can probably refer to other pages that are topically related to the content you are writing. Utilizing tags that are relevant to the topic can help the reader find other pages with similar themes, which make a semantic “inlinks sillos” or spreading the link juice, a lot of sense.

3. Write Your Inlinks In The Wikipedia Way

Remember how Wikipedia catches you with its internal links. You land there to research a famous personality and end up reading all their works, personal life journeys, and more. That’s the magic of well-written internal links – they’re informative, relevant, and naturally guide users deeper into your website.

The Wikipedia secret is also not a whole new strategy – just use descriptive anchor text. Don’t settle for generic links like “click here” or “learn more.” Instead, use keywords that accurately reflect the content of the linked page.

4. Don’t Forget The Deepest Pages

Internal linking isn’t just about connecting popular pages. Unearth the hidden gems of your website – those informative, in-depth articles buried within your content. Strategically link to them from high-authority pages, like your homepage or popular blogs.

This helps search engines discover and index these valuable pages, potentially boosting their ranking for relevant long-tail keywords. Remember, a well-linked website is like a well-connected city – every corner deserves to be accessible and discoverable.

5. Don’t Be Afraid To Set Up Nofollow And No-index

Internal linking isn’t a one-size-fits-all approach. There might be pages on your website that you don’t necessarily want search engines to prioritize, like privacy policies or login pages. This is where the power of nofollow and no-index tags comes in.

A nofollow tag instructs search engines not to pass on link equity (ranking power) to the linked page. This is useful for both internal and external links pointing to the content you don’t want to endorse, but it can also be used strategically for certain internal links. For example, you might add no-follow links to contact forms, blog category pages, or other non-content pages.

Here’s how you can add a nofollow tag to a link: <a href=”https://website.com/example-link” rel=”nofollow”>Anchor Text</a>

A no-index tag tells search engines not to index the page altogether. This can be helpful for temporary pages or pages with duplicate content. However, use no-index sparingly because valuable content might get accidentally hidden from search results.

You can use this code to add a no-index tag to a link: <a href=”https://website.com” rel=”noindex”>Anchor Text</a>

Closing Remarks

Internal linking might not be flashy, but its power is undeniable. Reasonably linking pages on your site can develop an intuitive and engaging user experience. Search engines will also take notice, appreciating the clarity and structure your internal links provide. Thus, do not belittle these unnamed champions. Dedicate some time and create a comprehensive internal linking strategy and blend it with the right external links to see unparalleled results on SERPs while enhancing user engagement on your pages.
