What is a semantic silo in SEO?
The semantic silo is an SEO architectural method which consists of organizing the content of a website by major themes. Each group of pages deals with a specific subject and is linked by a structured internal link.
The purpose of a semantic silo is to help search engines understand the structure and main topics of a site. By grouping content around the same theme, a site strengthens its relevance and authority on this subject.
This approach also makes it possible to improve user navigation by offering them a logical path between pages linked to the same theme.
Semantic silo principle
The principle of the semantic silo is based on a hierarchical organization of content. Each main theme has a central page called a pillar page, around which more specific pages are structured.
- a pillar page that presents the subject in a global way;
- secondary pages that delve deeper into sub-themes;
- an internal link that connects the pages together.
This structure makes it possible to create a coherent set of content around a specific theme.
Why use a semantic silo in SEO
Using a semantic silo can improve the visibility of a website in search engines.
- it clarifies the structure of the site for search engines;
- it reinforces the thematic authority of a site;
- it improves the distribution of the internal mesh;
- it makes navigation easier for users.
By grouping content by subject, a site shows search engines that it covers a topic in depth.
How to build a semantic silo
Creating a semantic silo generally begins with an analysis of the keywords and main themes of a site.
Identify the main themes
The first step is to identify the major topics related to the site's activity. Each theme can become a separate silo.
Create a pillar page
For each theme, a main page is created in order to present the subject overall. This page serves as an entry point to more specific content.
Develop complementary content
Secondary pages are then written to deal with more specific aspects of the subject. They enrich the silo and deepen the theme.
The role of internal networking in a silo
The internal network plays a central role in the functioning of a semantic silo. Pages from the same silo are linked together to create a coherent structure.
This mesh allows authority to be transmitted between pages and helps search engines understand the relationships between content.
- secondary pages point to the pillar page;
- the pillar page links to the secondary pages;
- pages at the same level can link to each other.
A well-constructed internal network reinforces the coherence of the silo and improves the flow of traffic within the site.
Semantic silo and semantic cocoon
The notions of semantic silo and semantic cocoon are often confused, because they are both based on a thematic organization of content.
The semantic silo generally corresponds to the overall structure of the site, with categories and pages organized by theme.
The semantic cocoon is a finer approach to internal networking, where pages are linked together according to a logical path based on search intent.
In a complete SEO strategy, the two approaches can be complementary.
Frequent errors in setting up a semantic silo
Certain errors can limit the effectiveness of a semantic silo.
- creating too many silos with little content;
- mix several themes in the same silo;
- produce content that is too similar;
- neglecting the coherence of the internal mesh.
To be effective, a semantic silo must remain coherent and treat a theme in depth.
