So we all know that the structure of your website is important for both user journeys and SEO but what do we mean by hierarchies and silos?
Website Content Silos
Silo’s of content effectively means categorisation of content based on similar topics. All of your content should be categorised and collected together in to similar topics as this makes it easier for users to navigate in between posts, pages and products and tells gives the right signals to search engines.
Think of your favourite website, can you see from their top navigation, or highest level of the website that content is joined together? If not then they probably aren’t doing themselves any favours.
Website Silo Structure
In this image taken from SEO Experiments even as far back as 2013 it has been advised to group content in to silos.
Users can easily, at a high level navigate through topics of content, or product ranges that are more relevant to them. This funnel aids the flow of users as well as search engines because search engines look for links between content and page rank flows more effectively this way.
By structuring your site you can influence how much page rank flows to specific pages and ensure that pages are easily crawlable and rankable which then drives traffic.
Ignore search engines here. Think about users. If you get it right for users, searxh engines will pick up on this.
