Internal linking: the complete guide to optimizing your SEO

What is internal linking?

Clear and simple definition

Internal meshing is the set of links on a website that point to other pages on the same site. It allows you to guide visitors in their navigation and help search engines explore, understand and index content. Good internal linking improves user experience and natural referencing by reinforcing the site's structure and transferring authority from one page to another.  

The difference between internal and external links and inbound/outbound links

It is important to distinguish between different types of links in order to understand how SEO works as a whole:

Visit internal links represent links between pages on the same site. Example: a home page that links to a product page.

Visit external links are links from your site to another site. Example: when you quote a source or recommend a site. 

Visit inbound links also known as backlinks, are links from other sites to yours. They're invaluable for SEO, as they boost your site's credibility with Google. 

Visit outbound links are links from your site to an external site. 

Why optimize internal links?

Improve SEO

Internal mailings, often underestimated, can strengthen a website's SEO. By intelligently linking your pages to each other, you make search engines' work easier and improve the visibility of your content.

Increase domain authority

Every page on your site accumulates "SEO value" over time. Visit internal networking allows this authority to be redistributed to other important pages. For example, if a very popular article links to a product page, it will pass on some of its SEO weight. This will enable the entire site to become stronger and gain credibility.

Facilitate page indexing

Search engine robots crawl the web by following the links. If some pages on your site are not linked to any other page, they may not be able to be accessed. never be discovered or indexed. By creating internal links to all your pages (especially the most important ones), you ensure that they are well explored, understood and referenced by Google.

Improve keyword positioning

Internal linking also allows you to better target your keywords. By using relevant link anchors, i.e. clickable words in your links, you tell Google what the pages you're linking to are about. This reinforces their relevance on these expressions and can improve their position in search engine results.

Improving user experience (UX)

Internal linking isn't just about improving a site's technical SEO: it also plays a key role in the site's development. important role in user experience. By guiding visitors smoothly and intuitively through your content, you enable them to better understand your offer, to quickly find what they're looking for and stay on your site longer.

Streamline site navigation

Good internal linking allows Internet users to easy navigation and logically between your site's pages. Instead of constantly returning to the main menu, users can follow links embedded in the content, which direct them to related or complementary pages. This makes reading more fluid, improves understanding of the site and naturally guides visitors on their journey.

Reduce bounce rate

When visitors land on a page and don't immediately find what they are looking for, they often leave the site This is what we call a "bounce". By integrating internal links to relevant pages, you offer users interesting alternatives before they decide to leave. This encourages them to explore further your site and significantly reduces the bounce rate.

Increase time spent on site

Time spent on a site is a behavioral signal positive for search engines. Effective internal linking encourages users to consult several pages in succession. By offering related articles, complementary products or in-depth pages, you hold their attention longerwhich can both increase their engagement... and improve your SEO ranking.

Boost conversions

Internal linking can also make a big difference improve your sales performance. By guiding visitors to the most strategic pages of your site, you can encourage them to make concrete actions : purchase, contact, quote request, etc. A well-thought-out network can transform traffic into results.

Direct users to key pages (products, services, forms)

How do you set up an effective internal linking strategy?

Implementing an effective internal linking strategy is not something that can be improvised. It requires a clear view of your site's structureWe take into account your existing content and your objectives. Among the steps involved in building a coherent, sustainable strategy, we first have a in-depth audit of your website.

Audit of your existing website

Before making any changes, it's important to analyze what already exists. An audit of your site's internal linking enables you to identify your site's strengths and weaknessesto know exactly where to act.

Identify the most important pages

The first step is to identify your strategic pages. These are the pages that attract the most visitors, convert the most, or target the most competitive keywords. These pages should become the central nodes of your mesh. This means they should receive a maximum number of links from other pages on your site. The more they are linked, the more their visibility and search engine positioning can improve.

Analyze site structure and tree structure

The tree structure is the way pages are organized, linked and accessed from the home page. A good tree structure should be logical, hierarchical and easy to navigate, both for users and for search engines. In general, it is recommended that no page should be more than 3 clicks away from the home page. Tools such as Screaming Frog, Sitebulb or Visual Site Mapper can help you analyze your site's tree structure.

Creating a page hierarchy

Not all pages are equal in terms of SEO value, which is why you need to structure your site around main content, called pillar pages, supported by secondary pages called satellite pages.

Defining pillar and satellite pages

Visit pillar pages are comprehensive, in-depth contents that deal with a central topic of importance to your site. They aim to rank for the most important keywords and should receive a maximum number of internal links. Around these pages, you can create satellite pages satellite pages: more targeted content that addresses a specific aspect of the main topic. Internal linking plays an important role here: satellite pages link back to the main page to reinforce authorityThe main page links to its satellites, enriching the user experience. This improves both the SEO of your main pages and the fluidity of navigation on your site.

Organize pages by theme (silos or semantic cocoons)

To take structuring even further, you can organize your pages into thematic groups called semantic silos or cocoons. The idea is to group together content dealing with the same subject (e.g. SEO, UX, e-commerce) in an internal network of coherent links, without multiplying connections to off-topic pages. The thematic silo is based on a clear, hierarchical structure (category > sub-categories > articles).

Choosing the right link anchors

The link anchorlinks, i.e. clickable text linking to another page, play an important role in internal linking. It helps search engines to understand content of the target page, and guides the user through navigation. 

Use relevant, natural keywords

The link anchor must contain keywords representative of the content of the target page. For example, if you're linking to a page on "local SEO", using an anchor such as "guide to local SEO" rather than "click here" would be more appropriate. This allows Google to better understand the context of the linkwhile giving users a clear indication of what they're going to find.

However, the priority remains the reading fluidity The anchor must fit naturally into the text, without forcing the use of keywords.

Vary anchors to avoid penalties

Using the same keyword anchor over and over again to point to the same page can be penalized by search engines. To avoid this, try to diversify your anchors: restatements, synonyms, long-tail expressions.

For example, instead of always using "local SEO", you can alternate with: "optimize your local presence", "SEO for local businesses", or even more neutral anchors like "learn more about this topic" right after a passage that discusses local SEO.

Strategically placing internal links

Beyond the choice of pages and anchors, location of links influence their effectiveness. Certain links are more visible, more clicked, and transmit more SEO value. That's why you need to think in the manner and the place where to embed your links in the site.

Contextual links in the body of the text

Contextual links are integrated directly into the content of a page. These are the most powerful, both for SEO and user experience. They fit in naturally in a paragraph, at a time when the user is already interested in the subject. This is the type of link most clicked and the one that transmits the most "SEO juice". To be optimized, it must :

• be relevant context,
• use an anchor claire and descriptive,
• do not interrupt the playback, but extend.

Links in navigation menus, footer, etc.

Visit navigation menus (such as the header, sidebar or footer) are fixed elements of the site that provide permanent access to certain main pages. These links reinforce the visibility of these pages, but are considered by Google to be less "contextualbecause they are not integrated directly into the content.

Here's an example:

They are essential for structuring the entire sitebut should not be your only method of internal linking. It's also important not to overload these menus with too many links, to avoid lose the user and reduce navigation efficiency.

Links in similar or recommended articles

Adding a "similar articles", "to read also" or "recommended" section at the bottom or side of pages is an excellent way to encourage exploration. This type of mesh encourages visitors to discover more content effortlessly, prolongs their time on the site and improves navigation depth.

Regularly monitor and optimize internal links

Establishing a good internal link is not a one-time action, but a long-term one. continuous work. SEO is constantly evolving, and internal linking is no exception. What works today may become less relevant tomorrow. So it's very important to monitor regularly to correct errors, detect opportunities and maintain a strategy that works. This can be done using the SEO analysis tools we'll look at below.

Internal linking strategies

The silo network

The silo is to organize your site into thematic sections called silos. Each silo groups together pages dealing with the same subject, linked to each other, but without any direct link to the other silos.

For example, a marketing site might have an "SEO" silo, another "online advertising" silo, and a third "social networks" silo. Each page in a silo links only to pages in the same silo. This method helps Google to understand the site structure and reinforces thematic relevance.

Semantic cocoon meshing

This type of mesh is based on the lexical richness and the content complementarity to create a network of pages linked around a single topic. Each "pillar" page is supported by secondary pages that delve deeper into the subject. These pages are all linked together, in a well-thought-out order, with natural link anchors. This method aims to respond to all research intentions around a theme and guide users and search engines through a reading path consistent and progressive.

Networking by category/theme

This approach is based on the site's natural organizationoften based on categories or sections. Each page in the same category is linked to the others, whether in the menu, in associated articles or at the bottom of the page. This is a simple method to implement, especially on blogs or e-commerce sites where content is already structured by section.

Common mistakes to avoid

Certain internal linking practices can harm your SEO or user experience. Identifying these common mistakes will enable you to optimize your strategy safely and avoid potential penalties.

Broken links (error 404)

Internal links to other pages deleted, displaced or misnamed generate a 404 error, i.e. a page that can't be found. These broken links have a detrimental effect on the visitor's experience. frustrate and interrupts their navigation. On the SEO side, they weaken the effectiveness of your internal mesh: link juice no longer circulates properly, and certain pages can go unnoticed by search engines. 

Excessive nofollow links

The nofollow tag tells search engines to do not follow a linktag, and therefore does not transmit any SEO value (PageRank) to the targeted page. This tag can be useful in certain cases (e.g. for non-strategic pages such as GTC, legal notice, privacy policy, etc.). On the other hand, its use on important internal links can harm your SEO. Overusing them is tantamount to blocking the circulation of SEO juice within your site. That's why vast majority your internal links are expected to remain in dofollowIn other words, they are free to be followed and taken into account by search engines. 

Too many or too few internal links per page

A page without internal links prevents users and search engines from browsing smoothly. It remains isolatedThis will hinder the flow of information on your site. On the other hand, a page containing too many internal links (especially if they are placed without logic) can become overloaded and difficult to read. In SEO terms, this reduces the impact of each link, as the value transmitted is dispersed among too many pages. The ideal is to add a number moderate links, well integrated into the content, and always related to the page's subject. The longer the text, the more links you can insert, provided they are really useful for the reader.

Lack of thematic coherence between pages

Linking unrelated pages weakens the structure of your site. Meshing must respect a semantic logic, so linked pages must deal with the following subjects related or additional. This enhances Google's understanding of the content and helps the user to progress naturally through the reading process.
