An SEO silo is a method of representing an SEO architecture for a website that organises its content into distinct clusters or categories of theme. This arrangement helps establish topical relevance and enhance user navigability, alleviating the effort of figuring out the content of the website on the part of users and search engines alike. Each silo is concerned with one particular topic or subtopic. Related content is usually grouped together and linked internally to create an organised hierarchy while establishing credibility in expert matters, activities that favour search engine rankings. An SEO silo further helps distribute link equity across the website, as links within a particular silo ultimately contribute toward the authority of that topic cluster.
