“Cornerstone Content” refers to the main, high-quality, and evergreen content pieces on a website that serve as the foundation of a site’s content strategy. These pieces are designed to be comprehensive, informative, and well-optimized, and they are typically used to rank well in search engines, attract and retain visitors, and establish a site’s authority and expertise in its niche.
Examples of cornerstone content can include product reviews, how-to guides, top 10 lists, tutorials, and resource pages, among others. Cornerstone content is usually updated and promoted frequently, and it is linked to from other pages within the site, helping to boost its relevance, authority, and visibility in search results.
