A group of related content pieces — typically several specific articles — all linking back to a central pillar page, organized around one broad topic to signal comprehensive topical coverage to search engines.
Why it matters
Search engines increasingly reward sites that demonstrate deep, comprehensive coverage of a topic, rather than a single isolated article — a well-built topic cluster can lift the ranking of the whole group, including pages that wouldn't rank as strongly in isolation.
In a sentence
"We restructured our blog into topic clusters, grouping every related article under the pillar page it should link back to."
