Deprecated schema type: markup with no rich result

What it means

The page uses a schema.org type that Google previously turned into a rich result but has since removed from its documentation and feature set. The markup is syntactically valid — Google will parse it — but no rich result, carousel, or SERP enhancement is produced. Detected dead types include HowTo, Special Announcement, Learning Video, Course Info (EducationalOccupationalProgram + courseMode), Estimated Salary (Occupation + estimatedSalary), Vehicle listing, Practice Problem, and the WebSite Sitelinks Searchbox (SearchAction with {search_term_string}).

Why it matters

Structured data earns value two ways: it informs the knowledge graph (always available for valid schema.org markup) and it powers visible rich results. When Google retires a rich result type, the second path closes permanently and the markup becomes inert for SERP features. Google removed a wide range of types in 2023-2026: HowTo (Sep 2023), Sitelinks Searchbox (Nov 2024, now auto-generated), Special Announcement / Learning Video / Course Info / Estimated Salary / Vehicle (Sep 2025), and Practice Problem (docs removed Jan 2026). Keeping deprecated markup is noise: it consumes parse budget and signals that structured-data maintenance is not systematic.

How to fix it

1. Identify the deprecated type — the issue detail names which one(s) were found on this page.
2. Confirm no rich result is generated using Google's Rich Results Test.
3. Remove the block if the deprecated rich result was its only purpose; strip only the deprecated properties if the block also powers a still-active type.
4. For the Sitelinks Searchbox, remove the WebSite + potentialAction block entirely — Google now generates it automatically for eligible sites.
5. Re-test after removal to confirm no active types were affected.

When it's not a problem

Do not treat ReadAction on Book as deprecated — it was partially un-deprecated in November 2025 and is not flagged. ClaimReview is ambiguous as of mid-2026 and is not flagged. If you mark up content for non-Google consumers (third-party tools, internal search, other engines), the Google deprecation does not affect those uses and you may keep the markup. FAQPage has its own dedicated rule and is not covered here.
