The silo structure in SEO is a type of website architecture in which content on a specific topic is grouped, isolated and interlinked. This creates clean and distinct sections of related content on your website. You can see that each silo consists of a main silo page and related content, all of which are interconnected. A silo structure for SEO requires a main page on a specific topic and secondary pages that have content related to the topic.
A silo is an excellent image for grouping pages and improving SEO. Just as silos in a group of farms work separately, maintaining their integrity and value, isolating a website improves website optimization around a topic. Your site is likely to contain information on a wide variety of products or services. With a silo structure, you group all the pages of your site into sections by topic and create those separate information groups.
With respect to blogs, isolation is the process of organizing related information on your site as a whole. This silo structure is often traced before a website is launched. If the lower pages of a silo didn't link to the top, the juice of any link created to the pages in the lower silo would hit a dead end as soon as they were created. Near the end, I'll tell you more about how to build a hard silo that can reinforce the soft insulation of your site.
However, let's consider that this isolation configuration also has some serious deficiencies that could affect your website. In a case study conducted by Moz, they found that Google evaluates the quality of a silo within a website and ranks pages within that silo accordingly. In addition, this isolation model has the power to direct live readers to more general and commercial pages of the website, even if they land on a long page found at the bottom of the structure. Also called content clusters, content silos improve website information architecture and user experience.
Applying an SEO silo architecture to your site also helps you choose more carefully the pages and content you want to improve with more current relevance. Before implementing a silo on your site, it's very important to create a mind map or at least an outline of the silo structure you want to present. I suggest that you use breadcrumbs when using silos to give Google a better understanding of the structure of silos. In fact, applying a silo can be so effective that you may see pages in your website structure rank better in search engines even before they receive their own backlinks.
Having a silo structure will guide users and search engines throughout your website in a clear and understandable way. The green arrow lines in each of the following examples of silos represent the direction in which internal links on the website will travel. While implementing a silo structure can be a challenge, it will help search engines to better crawl, index and rank your website. The titles should accurately describe the content of the page and subtly reinforce the differences between this page and the rest of the content of the silo website.
