An SEO silo, also known as website silo architecture, is a method of organizing a website’s pages into interlinked, isolated groups based on a specific topic.

En example of an SEO soli

The concept behind an SEO silo is that a topically-related group of pages can benefit from contextual links from other topically-relevant pages, as well as the flow of link equity within the silo.

One of the questionable aspects of the classical SEO silo structure is the prohibition of internal links between silos.

Here at Ahrefs, we believe that internal links can be placed anywhere as long as they’re relevant and beneficial to users. Additionally, we recommend using the ‘pyramid’ website structure over silos.
