Page uses schema types Google deprecated for desktop rich results in H1 2026 (HowTo / PracticeProblem / MathSolver)
Schema markup is code added to a webpage that describes its content in a structured way, so search engines can sometimes display it as a rich result, such as a step-by-step box, instead of a plain blue link. This site still uses schema types, HowTo, PracticeProblem and MathSolver, for which Google has reduced or removed rich result support. Check Google's current structured data documentation for the exact status of each. The markup itself is not broken, but it may no longer produce the rich result it was added for.
Why this matters
This doesn't break anything visibly, but deprecated schema is a quiet freshness signal to Google and AI crawlers that a page hasn't been actively maintained, which can work against it when freshness is weighed against newer competitor pages. The one exception is if AI-engine citation is specifically your goal, since some AI systems still read HowTo schema even though Google's rich results no longer act on it.
How to fix it
Your developer and content team should migrate any HowTo content into a standard Article with an ordered list and Step schema, and remove or replace PracticeProblem and MathSolver markup with Question and Answer schema instead. This is a markup swap rather than a content rewrite, and the engine estimates about 2 hours of work once the affected pages are identified.
