The shift

Search systems increasingly evaluate a site’s coverage of a subject as a whole, not just the strength of one ranking page. A single excellent article competing against a thin site rarely wins the way it used to — engines now weigh how completely a domain represents an entire topic space. This is the core idea behind the content strategy guide.

What this means for you

Instead of chasing isolated keywords, group content into clusters: a pillar page for the core topic, supporting pages for related subtopics, and clear internal links tying them together. Depth and structure now matter more than raw page count — an approach that also feeds directly into GEO optimization and citation-worthiness.
