How to make a SILO site structure

Short description

The SILO site structure is a technique for organizing content on a website by creating hierarchical thematic sections. Each page is placed in its specific block, connected by internal links. Breaking the site into thematic blocks will aid search engines in recognizing the topic of the site, and a hierarchical structure will improve UX by simplifying navigation. A SILO structure promotes better SEO optimization by efficiently distributing reference weight, as all pages relate to each other by topic, while a lower rejection rate reduces site bounces. Other site structures include Cluster or Hubs, Pyramid or Tree, and Chinese Site structures.

How to make a SILO site structure

Making the site convenient and understandable for visitors, as well as optimized for search engines, is the task of every SEO specialist. One of the key elements influencing these factors is the structure of the site. Today we will talk about how to structure a site according to the SILO method in order to improve its position in search engines and increase traffic.

What is a SILO structure?

The SILO site structure is a technique for organizing content on a site, where each page is in its place in a hierarchical structure. It implies the creation of thematic sections (blocks), inside which there are pages related to each other by topic and semantic meaning.

Before the implementation of the SILO structure, the site looks like a chaotic cluster of various pages. Take a look at this jar of balls, for example, and think about how it will be perceived by search engines.

In such conditions, it is difficult for the search engine to understand what topic the site is devoted to. To simplify the task, it should be divided into different groups, then the search engine will more accurately recognize each of them.

For this to work within a single site, the content should be about a common topic, but broken down into thematic subcategories. For this, groups of pages need to be connected with each other by internal links.

What are the benefits of a SILO site structure?

  1. Improved SEO optimization. Search engines understand the structure of a site better when it is organized according to the SILO methodology. This allows you to attract more traffic to the site. This is what a study conducted by the Russian Slay company tells us.SEO Siloing: How to Build a Website SEO Silo“. Summary of research results

    1. The SILO structure improves the site’s SEO performance by creating a clear and logical structure.

    2. It requires careful site planning, as well as an understanding of keywords and those that are relevant to CA.

    3. Improves UX by making it easier to find the right content

  2. Simplifying navigation for users. The thematic structure of the site makes it easier for users to find the information they need. This increases the usability of the site and reduces rejections. And as we know from the recent past leak from Yandex Bounce rate is one of the important behavioral factors. The lower the rejection rate, the better.

  3. The best reference weight distribution. When all the pages of the site are related to each other by topic, the distribution weight is distributed more evenly between them.

How to make a SILO site structure: a step-by-step guide

  1. Break the website into thematic blocks. Determine the main topics that are presented on your site and create a separate block for each topic.

  2. Create a hierarchy of pages. In each block, define a main (root) page that will link all other pages within the block.

  3. Create an internal link. Inside each block, list all the pages together. This will allow search engines to better understand the structure of your site and index its pages faster. In addition, it will simplify navigation for users who will be able to quickly find the information they need.

  4. Use keywords. For each block, identify the main keyword that will be most relevant to that topic.

A specific example

It is important to understand that although this is a specific example, it is an example. It is clear that this site has more pages.

Let’s say you have a car repair site and you want to structure your site using the SILO methodology. In this case, you can divide the site into the following thematic blocks:

  1. Engine. In this unit, you can collect all the pages related to car engine repair, such as “Engine Diagnostics”, “Cylinder Head Repair”, “Timing Kit Replacement”, etc. engine”.

  2. Hodova. In this block you can collect all the pages related to the repair of the box and drive of the car. This can be the page “Replacing suspension parts”, “Replacing stabilizer bar and bushing”, “Replacing lever, swingarm”, etc. The main page of this block can be the “Chassis Repair” page.

  3. Electricity. In this unit, you can collect all the pages related to car electrical repair, such as Electrical System Diagnosis, Battery Replacement, Alternator Repair, etc. The main page for this unit can be the Electrical Repair page.

Each block should contain several pages related to the topic. Inside each block, you need to use internal linking to connect all pages to each other by topic. For example, on the “Engine Repair” page, you should insert links to other pages from the “Engine” block, such as “Engine Diagnostics” and “Changing Oil and Filters”.

Red arrows indicate a link within one level, black arrows within one branch.


It is worth noting that there are SEO specialists who believe that the SILO structure of the site is not effective. For example, in the Ahrefs study “SEO Silo Structure: Why It Makes No Sense» says that it often makes sense to put a link from one page of a particular block to another in another block. But once we do that, we lose the SILO framework.

Briefly about other methods of structuring the site

Clusters or hubs

In this structure, all pages are placed in their hubs (clusters) and linked between similar services in another hub.

Arrows of different colors indicate a link of similar pages, for example, the “Transmission Repair” page, which belongs to the “Transmission” hub, is also linked to the “Repair” hub.

A pyramid or a tree

The advantage of this structure is that the pages themselves are fairly rigidly anchored in the hierarchy, but can link to any other pages if the link is appropriate.

The most popular structure in my opinion, in fact, it is similar in many ways to SILO, but in this structure, the pages are linked primarily by content and logic. If the previous types of structures can be automated, then they can be done well only by hand.

Although I recently tried one plugin for WP, it is built on the basis of chatGPT and automatically offers to put a link if it finds the right page on the site. But it still works far from flawlessly.

Chinese site structure

A living meme, just legendary funny sites for Europeans, of course.
In China, the structure of a website is often designed so that most pages are linked to the main page. This is due to the fact that the Baidu search engine gives the most weight to links to the main page.

Here is an example site

Please note, this is all a link


Creating a SILO site structure is one of the key practices of site SEO optimization. This structure has its disadvantages, but also a lot of advantages. Its main advantage is a rigid structure.
