Why it matters
FAQ rich results stopped showing on 2026-05-07, HowTo was removed in 2023 and the sitelinks search box in November 2024. The markup is harmless but earns nothing.
How to fix it
Don't add new FAQPage/HowTo/SearchAction for rich results. Keep visible Q&A in plain HTML (question headings with direct answers), which assistants lift well.
