Create a Content Hub Table for SEO

Develop a comprehensive content hub schema for [TOPIC] with a three-tiered structure. Construct a table that categorizes search terms into tier 1 (general topics), tier 2 (subtopics), and tier 3 (specific long-tail keywords). Ensure that each keyword is unique and appropriately nested under broader terms. The resulting list should cater to the search patterns of consumers interested in [TOPIC]. Compose this in [LANGUAGE].
