Topical clusters are groups of related content that centre around a main topic, or "pillar" page.
These clusters help to create a clear and organised content structure that search engines can easily understand, which in turn boosts your site's relevance and authority in that area.
By linking all the related content back to a central pillar page, you not only improve your site’s SEO but also provide a more comprehensive resource for your visitors, helping to keep them engaged and on your site longer.
