Articles, series and the full MasterClass course list
MasterClass articles. The /articles library dwarfs the class catalog: how-to guides, recipes and explainers under the byline MasterClass, filed in categories that follow the older taxonomy - Food, Design & Style, Wellness and the rest - rather than the 13 class categories. Each article carries a last updated date, read time and an average rating with its count, usually with a linked instructor and a featured class, so the library maps which class each search-driven page promotes. Recipes add schema.org Recipe data: ingredients, prep and cook times, yield and cuisine. The hub's own latest rail has not moved for years, so freshness is read article by article.
MasterClass series. Original series such as GOAT are cut into episodes, each with its own expert, bio and runtime, and some list episodes newest first, so episode order gets a field of its own.
The full course list. The class sitemap carries series under /classes/ paths but leaves Sessions out, and one title shows up under several categories. Complete MasterClass course offerings come from merging the sitemap with the category pages and deduplicating on the class id.
Certificates and Executive. Certificates form a separate catalog of 15 to 20 hour programs with projects and learning paths, and MasterClass Executive runs application-based cohorts with a deadline, a start date and a faculty that mixes executives with Chicago Booth professors.
