The searcher never takes the course. It is an operations manager buying for forty people, so the page has to answer how it is rolled out, chased and reported — questions no individual learner would ever ask.
Platform comparisons are made by people with money approved. Those visitors read specifications and pricing carefully, so a page that hides the cost loses them to a competitor who publishes it.
Companies with existing material search for conversion. A firm sitting on slide decks and manuals wants them turned into something trackable, and that phrasing is nothing like a platform search.
The long tail is sector by sector. Training for care staff, for scaffolders, for kitchen teams: each combination is a small search with an exact buyer, and together they outweigh the generic terms.
