Pottery carries more demand than everything else combined, and it is searched as a thing to do rather than as a subject to study. A school with a wheel and a kiln that says so plainly captures an audience the painting pages never reach.
Beginners search differently from improvers. For beginners, for absolute beginners, no experience needed: those phrasings convert because they answer the fear first and the curriculum second.
One-day workshops sell as presents. They are searched in November and December by somebody buying for another person entirely, which makes them the only page on the site that needs a gift voucher next to it.
Portfolio preparation follows the application calendar. Parents look months before the deadline, competition is minimal, and those students often stay on for years afterwards.
