Content Clustering is an SEO strategy that organizes content into topical groups. The idea is to create a pillar page on a broad topic and then link to more specific articles related to that topic. This method improves the structure of your site and helps search engines better understand the relationship between your content.
For example, if you have a digital marketing blog, you could have a pillar page on “Social Media Marketing” and then specific articles on “Instagram Strategies,” “Facebook Advertising,” and “Twitter Tactics.” Not only does this approach improve the structure of your site, but it also increases the time users spend on your site and improves your SEO.
