Two of our guide pages are instructions and one is a list, so only one of them emits a HowTo

Try this: curl -s https://pub-trivia.app/guides/how-to-host-a-pub-quiz \ | grep -o '"@type":"HowTo"' # "@type":"HowTo" curl -s https://pub-trivia.app/guides/pub-quiz-round-ideas \ | grep -o '"@type":"HowTo"' # nothing Two pages in the same cluster, built from the same component, with the same metadata pipeline behind them. One of them is a numbered procedure a reader follows from start to finish. The other is a list of ideas you pick from. Only the first one is a HowTo, and the restraint is the part of structured data that is actually hard. We run a 72 page marketing site for quiz software.
