They still work — arguably better than ever, because FAQ and Q&A pages are structurally exactly what AI answer engines want: one clear question, one direct, self-contained answer, easy to lift and quote. The key is discipline: one distinct intent per page or entry, not a long list of loosely related questions crammed onto a single URL.
This is the model Kando's own Answers wiki follows — each question gets its own page with FAQPage schema attached, so it can be indexed and cited on its own terms rather than buried in a longer article.
