Content silos are important for SEO because they help search engines understand your website content more easily.
When a search engine crawls your site, it wants to ascertain exactly what your content is about, how it’s structured, and where it’s located.
By utilizing silo architecture, a website is able to provide the type of structure that makes it simpler for search engines to complete this task.
This technique not only helps you improve SEO, but it also helps you improve usability.
Some websites contain content that can seem disjointed because there is no clear way to understand how the web pages are related to each other. However, siloing your content by using taxonomy or subcategories can greatly improve user experience. It helps visitors better understand how each piece of content relates to each other.
