Internal linking for SEO: Why and how? (2024)

Before your content can rank, it needs links. Google finds your posts and pages best when linked to from somewhere on the web. Internal links also connect your content and give Google an idea of the structure of your website. They can establish a hierarchy on your site, allowing youto provide the most important pages and posts with more link value than other, less valuable pages. So using the right internal linking strategy can boost your SEO! In this article, we’ll discuss the importance of internal linking, how to approach it, and how Yoast SEO can help you with internal linking.

What are internal links?

An internal link is any link from one page on your website to another page on your website. Your users and search engines use links to find content on your website. Your users use links to navigate through your site and to find the content they want to find. Search engines also use links to navigate your site. They won’t see a page if there are no links to it.

There are several types of internal links. In addition to links on your homepage, menu, post feed, etc., you can also add links within your content. We call those contextual links. Contextual links point your users to interesting and related content. Moreover, they allow search engines to determine what content on your site is related and its value. The more links a significant page receives, the more important it will seem to search engines. Therefore, good internal links are crucial to your SEO.

Internal links vs. external links

Every website — even online stores — consists of internal and external links. Internal links connect pages and posts on your website, and external links connect your pages to other websites. This post focuses on internal links and what they mean for SEO. See our posts on link building if you want to get more external links pointing to your site.

Why are links important to Google?

Internal linking is an essential factor for Google and other search engines. But why? Google follows links to discover content on websites and to rank this content in the search results. If a post or page gets many links, this signals to Google that it’s an essential or high-value article. This counts for internal as well as external links.

Internal linking is something you control as a site owner. You’ll guide visitors and Google to your most important pages with the correct internal links. Our internal linking tool (not available yet in Yoast SEO for Shopify) can help you suggest related posts to link to!

Internal links establish relationships between content

Google crawls websites by following internal and external links using a bot called Googlebot. This bot arrives at the website’s homepage, renders the page, and follows the first link. By following the links, Google can work out the relationship between the various pages, posts, and other content. This way, Google finds out which pages on your site cover a similar subject matter.

For example, this post will have links to the ‘Content SEO’, ‘Internal linking’, and ‘Site structure’ tags. We make sure Google understands that the content on those pages is related to the content of this post by adding these links.

Internal links help search engines better find your content

As websites grow in size and complexity, orphaned content becomes an issue for many. Orphaned content refers to pages on your website that have no internal links pointing to them. This issue is because search engines can’t find and index them without any internal link to lead the Googlebot to these pages.

Even though websites nowadays have sitemaps that list the URL of — most — pages on your site, search engines may take a long time to reach these pages eventually. This is especially true for very big websites that take a lot of resources to crawl or newly created sites that don’t get visited often by Google. Adding internal links to your newly published pages provides search engines with more ways to reach those content.

Link value

In addition to understanding the relationship between content, Google divides link value between all links on a web page. Often, the homepage of a website has the most significant link value because it has the most backlinks. That link value will be shared between all the links on that homepage. The link value passed to the following page will be divided between the links on that page and so on.

Therefore, your newest blog posts will get more link value if you link to them from the homepage instead of only onthe category page. And Google will find recent posts quicker if they’re linked to from the homepage.

When you understand that links pass their link value on, you’ll understandthat more links to a post mean more value. That’s because Google deems a page with lots of valuable links more important; you’ll increase the chance of that page ranking.

Setting up an internal linking strategy

It’s crucial for your SEO to evaluate and improve your internal linking strategy regularly. It’s one of the ways to improve the fitness of your website. By adding the right internal links, you make sure Google understands the following:

  • the relevance of pages;
  • the relationship between pages;
  • and the value of pages.

There are several things to consider to set up your internal linking strategy. How you go about it depends on your site and goals, but the following steps are a good rule of thumb.

1. Determine the ideal structure for your site

We always advise website owners to imagine their website as a pyramid. On top of it is your homepage; below are some sections or categories, and further down are individual posts and pages — possibly with subcategories in between.

Internal linking for SEO: Why and how? (1)

Your website’s menu should reflect this structure if you do it well. In our Ultimate guide to site structure, you can read how to create the best site structure for your site.

2. Decide what your most important content is

It would help if you determined what your most important content is. If you’re not sure, please read our article on cornerstone content. In short, it’s your best and most complete content about the core of your business. It’s the content you want people to find when searching for topics or products you specialize in.

You must add many links to inform Google that this is your most important content. There are various spots from where you can link to your cornerstone content. Here, we’ll give the most common options, from your post’s copy to your navigation.

3. Add contextual links

When you’ve written various articles about a certain topic, you should contextually link them. This will show Google – and your users – that those articles are topically related. You can link directly from sentences in your copy or add links at the end of your post.

Moreover, you want to show Google which articles are your cornerstone: your most complete article on this topic. To do so, you must add a link to the cornerstone in all articles on this topic. And don’t forget to link back from the cornerstone to the individual posts.

Contextual linking: an example

Our blog has a cornerstone content article called ‘The ultimate guide to keyword research’. This post will rank for all related search queries about [keyword research] in Google search results.

So we’ve added links from other relevant articles, such as ‘7 keyword research mistakes to avoid‘, ‘ What is keyword research‘, or ‘Focus on long tail keywords‘ to the mainarticle. And we link back from the main article to these posts. In doing so, Google will understand that the ultimate guide contains the most informationabout [keyword research]. So, in the end, Google will rank the ultimate guide above the other shorter posts about keyword research.

4. Link hierarchical pages

If you have hierarchical pages on your website, link parent pages to their child pages and vice versa. Also, don’t forget to link sibling pages to each other. These pages should be related to each other on a well-organized site, and connecting them like this make perfect sense.

Read all about linking parent and child pages for SEO.

5. Consider adding a related post section

You can find many plugins and modules to add complete related post sections to your posts. This is an excellent way to show your posts to more visitors. If you use one, we recommend testing whether the related posts are related. If you’re not sure, linking topostsmanually is probably best. That’s what we do on Yoast.com – we select a related post manually (or with a bit of help from our internal linking tool– more on that later) and place a link to that post at the bottom of the article. The related links block in Yoast SEO Premium helps you do this in a jiffy.

We explain this in detail in this post about linking to related posts.

6. Try adding navigational links

Besides linking from topically-related posts and pages, it’s possible to make your cornerstone content more authoritative by adding links from the homepage or the top navigation menu. It would help if you did this with the posts and pages most important to your business. This will give these posts or pages a lot of link value and strengthen them in Google’s eyes.

7. Add links to your taxonomies

Taxonomies, like categories and tags, help you organize your site and help users and Google understand your content. Ifyou have a blog, adding internal links to the taxonomies that the post belongs to could be beneficial. Adding links to the category and tags helps Google understand your blog’s structure andhelps visitors navigate related posts more easily.

For instance, on the first page of our SEO blog, we link to several tag pages, including technical SEO and SEO basics.

8. Add links to your most recent posts

A good practice after you publish a post or page is to link to that newly published post from other content on your site. Of course, the posts or pages that link to the recently published post must be of a similar topic. You shouldn’t just link to this new post from a random post or page on your site.

Now, this might sound daunting, especially if you regularly publish content. But it’s worth the hassle, as you won’t end up with a bunch of orphaned content that needs fixing. Besides, adding internal links to your most recent posts ensure that search engine crawlers can crawl and index them when they land on other pages on your site.

9. Consider adding links to popular posts

The last option to mention is creating internal links to your website’s most popular posts or pages. Preferably create these sections in the sidebar or the footer of yourwebsite to have them appear on all pages and posts. As link value passes to these most popular posts from many different pages, they get a boost. Besides, the posts will be more accessible for visitors, increasing traffic – and more traffic is a positive sign for Google.

Nofollow links

You also probably have links that aren’t important for SEO on your website. For example, if you have a login link for your clients on the homepage,you don’t want to leaklink value to your login page – that page doesn’t need to rank high in the search results.

You used to be able to prevent losing link value to unimportant links by giving them a nofollow tag. A nofollow tag asks Google not to follow the link, so no link value is passed. Now you might think: “I’m going to nofollow less important links to give the most important links more link value.” While this worked in the past, Google has become more competent. Now it seems that the link value for those nofollow links doesn’t automatically flow to the other links on the page. The nofollow link will be counted as a link, and the link value will be lost. Thereforeit makes more sense to have fewer links on a page instead of nofollowing some of the links.

Adding a nofollow tag doesn’t mean those target pages can’t be found in Google’ssearch results. You should give them a noindex tag if you don’t want pages or posts to appear in the search results. The noindex tag means that Google shouldn’t render the page and shouldn’t give the content a place in the Google index to show up in the search results.

Anchor texts

Once you have decided which links should be on a page and which pages should get link value, using the correct anchor text is essential. The anchor text is the clickable text that visitors see. For example, the anchor text of the two internal links in the example below are ‘link schemes’ and ‘paid links’:

Ifyou over-optimize anchor text, you might hurt your website. Byover-optimizing, we mean keyword stuffing. Previously, you could give all anchor texts the same keyword, and Google would rank your site higher for that keyword. Nowadays, Google is smart enough to understand that the content around the anchor text says more about the relevancy of a keyword than the anchor text itself. So please ensure the anchor text looks natural in your copy:it’s OK to use keywords but don’t add the same keywords to every link’s anchor text.

Internal linking in Yoast SEO

Yoast SEO includes several checks and features to help you improve your internal linking.

On a post level, the Yoast SEO plugin helps ensure you give internal links some thought. In the plugin meta box — or the sidebar, as shown below –, the internal link assessment of Yoast SEO checks whether you’ve created links to other pages on your website in your text. It also checks if these links are followed or nofollowed.

For Yoast SEO for Shopify, this check only works on posts or pages. You do not have internal links on your product pages or product descriptions because you want to keep customers there — not send them to another part of your site. You need your customer to convert as quickly as possible. An essential part of Shopify SEO, right?
