Creating silos gives you a clear strategy in building content that’s structured and links across the site. Silos help readers and search engines understand the overall theme of your website. It became a standard for how to emphasize the expertise of your website the focusing the main topic of your site in a hierarchical way.

What is a Silo Structure?

You might have entered a library in your school at least once in your life. If you have noticed every book inside the library are organized and separated to different category; be it about Science, Mathematics, Fiction, or Non-Fiction. This process of categorizing content is called content siloing, the same procedure done for your website.

A silo structure is a design of a deep site structure where the site content is accordingly organized. A silo consists of hierarchical groupings determined by topics and subtopics. In another way, it is like sorting the contents of your website into categories and sub-categories. 


Content Silos often used to help readers and search engines understand your website’s overall theme and content. Since a silo organizes a website’s content, it will give the users the convenience of what the site is about, how it is structured, and where the contents are based.

Contents that are topically related and relevant to each other should go together. Google and other search engines favor websites that cover topically relevant content in their silo. You will get better results in the SERPs if you cover all large search queries that people are using when searching for information on Google.

2 Types of Silo Structure

There are two types of content silo structures that you can build for your website; Physical Silo for directory structure and Virtual Silo for linking structure.

To get a deeper understanding of the two, let’s discuss both structures separately.

What is a Physical Silo?

A physical silo is an organization you create in the directory of your website. Using a physical silo in your website is like making a filing cabinet to organize related content and pages. Each filing cabinet should represent each of your website themes, and the folders in each cabinet represent the sub-categories of the matter. 

For example, your business is a flower shop, and you offer flowers for weddings and for birthdays.

Your physical silo will look something like this:

○ Wedding Flowers

  • White Roses 
  • Red Roses
  • Pink Roses
  • White Tulips
  • Red Tulips
  • Calla Lilies

○ Birthday Flowers

  • Yellow Roses 
  • Red Roses
  • Pink Roses
  • Lilies
  • Sunflower
  • Orchids

For a physical silo, your URL structure for the wedding flowers pages, for example, may read as follows:

<a href="yourflowershop.com/wedding-flowers/white-roses">anchor text</a>
<a href="yourflowershop.com/wedding-flowers/red-roses">anchor text</a>
<a href="yourflowershop.com/wedding-flowers/pink-roses">anchor text</a>
<a href="yourflowershop.com/wedding-flowers/white-tulips">anchor text</a>
<a href="yourflowershop.com/wedding-flowers/red-tulips">anchor text</a>
<a href="yourflowershop.com/wedding-flowers/calla-lilies">anchor text</a>

As noticed, each subtopic falls under the “wedding flower” directory on the website. The same rule applies to “birthday flowers”.

What Is A Virtual Silo?

A virtual silo is a connection you created through interlinking related pages on a website. Unlike physical silo, you don’t need to create folders and separate categories in your site’s director. You can easily link pages within the same theme and topic to hint readers and search engines that a stable connection between the interlinked pages.

Each content within the virtual silo is linked to every other page within the same silo. But you need to keep in mind that the silos themselves do not link to each other. In a simple sense, using our example above, you can interlink every topic within the wedding flower silo but, you cannot link a single wedding flower page to the birthday flower silo.

In implementing a virtual silo structure, you need to make sure that every silo has a category page and at least five (5) supporting pages. The category pages will link to the supporting page also the entire supporting pages will link to the category page. If you link to the category page all the supporting pages should all link to one another. You can achieve it by creating a navigation list of all the links towards the bottom of all the pages that feature other pages on their silo.

Using your target keyword that represents the category in the supporting pages will help you rank up. It also emphasizes the theme of the silo and will make it easier for the search engine to search for your content.

Linking Different Virtual Silos

Making the outgoing link point to the category page for other silos is a must in linking two different silos. Linking supporting pages to one another will hinder the all-inclusive essence of the SEO silo structure. 

If you must link between two different silos, make the outgoing link point to the category page for the other silo. Do not link supporting pages to one another, as that will interrupt the all-inclusive nature of the SEO silo structure.

If you want the content to stay as separate as possible, then try linking the category pages. It’ll show search engines that you are transitioning to an entirely new silo. Always remember that if you want to keep linking within virtual silos, you need to build and create new silos for your websites.

Improve Your SEOs Practice with Silo Structures

The main point of this is that the organized content will improve the user’s experience which will boost the site’s SEO. Constructing a silo structure for your site will give you a strategy that can help in building content that’s structured and links across the site.

If you use a CMS platform, you can use a third-party tool to help create siloed content. There are many plugins available to help boost WordPress SEO including ones for creating silo structures. You can find all-in-one SEO plugins that will guide your content planning strategies.
