Every business on the planet wants their website to rank number one for every keyword that relates to their business. Leveraging internal links for SEO is one of the easiest ways to increase your changes of locking in that number one ranking.
And why not? Billions of users turn to Google on a daily basis to answer their questions or find what they’re looking for.
A problem, however, lies in the simple fact that the internet is a huge place. Even Google only remains the top search engine worldwide because it quickly and consistently provides value to users. If Google didn’t efficiently serve users content highly relevant to their search queries, people just wouldn’t use it.
Though Google’s algorithm continues to be opaque, we know that clear, consistent web design matters more than ever. The foundation of your website is the content, but the connective tissue is the internal link.

An internal link is created when a link is added from one page on a website to another page on the same website. These are all internal links because they share the same root domain.
There are a variety of ways you could breakdown the different types of internal links. Here at DOM, we define them based on the general location of where the internal links are placed.
- Navigational Links: these links are commonly found at the top of a webpage or in an HTML sitemap. They are used to help visitors move around your site to the most important or most trafficked destinations.
- Sidebar Links: these links had their hey day in 1990’s and 2000’s when the majority of internet usage was tied to a desktop or laptop computer. With today’s modern web design being focused on a mobile-first, responsive experience on an iPhone or Android device, these links are less prevalent. You will commonly find sidebar links point users to areas of a website that are complementary to what they are viewing – like popular blog posts or related products to what a visitor is currently viewing.
- Contextual Links: these links serve as a reference point to other related content around the web. Contextual links may be indicated by a “click here” call to action or a “read more” statement. Say you own a sporting goods ecommerce site that points you to the company blog. On that blog, there is a post compiling the top 10 basketball shoes. Since each shoe is available for purchase on the site, you post a direct link to each individual product page in an effort to turn readers into potential customers.
Basically, any link on a page that takes a user to a different page on the same website is considered an internal link.
Internal links are usually much easier to create and manage than external backlinks, which are created when another website links out from their domain to anywhere else on the web.
Because of their simplicity, they are often overlooked. But a solid internal linking strategy can have a huge impact on your site’s rankings and performance in organic search.
Not only can a defined internal link structure contribute to a positive, intuitive user experience, but Google can also better understand the content on a site with clear, ordered internal links.
Once Google has a greater understanding of the relevance of the content on your site, it can rank your content higher. It’s no coincidence that Google Search Console has a report specifically dedicated to internal links.
The internet is gigantic and is growing every day. The service that Google provides is a simplified way to navigate this seemingly infinite space by providing pages that are relevant to user searches. Before search engines like Google, the best way to navigate the web was to use directory services that categorized websites by content type (think Yellow Pages). A few of these directories still exist, but they are simply too large to be useful.
If you clicked down to this question, hopefully you did so because you’ve just found a post that is getting some rankings or traffic. If your goal is to find out how many contextual internal links you should place in a page to benefit other priority pages on your site, this is the right place for you.
Side note: if you’re trying to determine how many internal links a page on your website should receive, this isn’t where you will find your answer. But keep scrolling, please, because we address that below.
How Many Internal Links On A Page Is Good?
Historically, conventional wisdom among the SEO community was that the optimum number follows this easy guide:
every long form piece of content and all important pages should have around 3-4 internal links pointing out to other pages, with an additional link per 300 words or so.
Granted, these were loose guidelines.
Then, of course, there was also the equivalent of the “it depends” answer, too. Many SEOs would have also told you that you have to add more or use fewer links depending on the actual content itself.
How Many Internals Is Too Many?
So, if you’re trying to determine the precise, accurate number of internal links you need to have pointing to your top pages, we hate to be the ones to break this to you…
There is no right answer.
Seriously, have you ever paid attention to a Wikipedia page before?
If you ever have a question about whether or not you should add an internal link from one page on your website to another, try asking yourself if placing that link improves the user experience.
If it’s useful, do it.
If it’s not useful, don’t.
Every link on a page that goes to a different page, no matter whether that page is internal or external, is called an “outgoing” link. If this sounds like every link on a given page, you’d be right! Every hypertext link we make is considered an “outgoing” link.
An incoming internal link refers to links that come from elsewhere to a given page. Therefore, the subject of our next section is these “incoming” links.
If you’ve read down this far, you know how to begin a strategy to add internal links pointing to your top website pages. For most websites, and for most pages on those websites, the optimum number of links that point back to your content should be around 20. As with everything else related to SEO, this number will get slightly smaller or larger depending on the size of your site.
The tool we use on our travels through the valleys of SEO, SEMRush, has a bunch of resources we can use to see the entire link architecture of a website (some of which also include external links). You can get a succinct internal linking score that gives you an overall target to aim for, while also including a series of suggestions for how you can improve your website’s score. A high score equals a good link profile, and any SEO tool with its price will have something similar.
As you see in the above example screenshot, the example website has an internal linking score of 71% overall, with a whole bunch of major issues presented for us, the stewards of the web, to fix. And that’s not even the whole list!
Another tool we use is Yoast SEO‘s integration with WordPress. It’s a handy way to do a lot of different SEO operations, often allowing us to see the parts of our pages that have the most impact on our organic rankings. If you don’t believe us about how important internal links are, you can believe Yoast–you can see, at a glance, exactly how many outgoing and incoming internal links each of your blog posts currently has, like so:
Those two icons on the right? Those are internal links. You can even sort your pages by the information in those columns so you know which blogs have the most (or least) internal links flowing into them and flowing out.
As you get to know what your link setup looks like, you will start to see a pattern emerge. This pattern of links is called the hierarchy.
The hierarchy of a website is important because it lets a user understand where they are on your site. Most websites are not single-page sites and therefore require some sort of directory-like structure for their content. Information is best understood when categorized into groups of similar pages.
If your website does not have a logical grouping of content, Google’s site crawlers may not be able to properly discover and index all your web pages. More importantly, users will likely struggle to navigate your site and quickly bounce.
Websites tend to fall under one of two hierarchical content grouping formations: flat and deep hierarchies.
A flat hierarchy is a website that has a larger number of categories than sub-categories. This type of web site is said to be “wider than it is tall,” in terms of graphical link structure.
A deep website hierarchy is a website that is organized into many sub-levels of information. Content is said to be more discoverable when it’s not hidden under multiple hierarchical layers. Deep hierarchy website structures are considered more difficult to use. This is likely due to how the human brain stores information and processes location.
Both types of websites can utilize a home page, which acts as a high-level information hub. In a flat hierarchy, a larger portion of the website’s content is understood when examining links from the home page. This is not only because there are more links from the home page, but also because those links do not lead to multiple sub-levels of information. This is compared to a deep hierarchy structure where the index page links to high-level categories of information that then link to more high-level categories of information.
Your website’s internal links and anchor text are essential to search engine optimization (SEO). Especially when a website is newly developed, these links will be the only links to your website’s pages and are pivotal to Google’s understanding of your website content. Within the Google Search Console, there is even a tool that analyzes your internal links to show you which of your pages you link to the most.
In general, every page of a website has the same header menu, top menu, and sidebar if there is one. Therefore, the number of links to each page of a website is typically approximately even. The hypertext that links from each menu to a category page should be descriptive of that category. Google uses this hypertext as an indication of what type of information is contained in the linked page (this is of course not the only method they use to determine page content, but it is a factor).
So spamming tons of internal links is the answer, right? Not exactly.
We recommend only linking pages when it seems natural. Performing historical SEO by going through old pages and blog posts and looking for internal link opportunities is highly recommended here. It is also important to try to diversify the hyperlink text leading to each page. As it pertains to link spam, in technical terms, Google is advanced enough to cross-check page relevancy by comparing the semantic distance between linked entities within the semantic web.
In layman’s terms, don’t spam links.
Google ranks pages, not web sites. While it is important to remember that domain rank is a dated metric, its core ideology is still in use and highly relevant today. This is easy to prove. In our 15-plus years of experience helping companies grow confidently online through digital marketing, we have never seen a website that ranks highly for a highly trafficked query and doesn’t rank for any other queries. Clearly domain authority has some effect here.
Although PageRank often cannot fully explain a website’s keyword rankings, it is a very good indication of where a website has the potential to rank. Since the original PageRank algorithm was largely released to the public by Google, it is possible to determine a numerical approximation for if the potential of each domain and page to appear in search results. The most popular tool for determining page rank today is the Mozbar and is one of many important tools in our SEO arsenal. Other commonly used web browser extensions for determining domain rank or domain authority include Ubersuggest, SEOquake, and the Ahrefs SEO toolbar.
