Rich results are the visible proof that your structured data is working. Star ratings beneath search results, FAQ dropdowns, breadcrumb trails, business information panels, product prices: these are all generated from schema markup that Google has validated and chosen to display. When rich results disappear, it means your entity signals are degrading.

Rich Result Types and Their Entity Signals

Rich Result Type Schema Source Entity Signal CTR Impact
Breadcrumbs BreadcrumbList Site hierarchy is structured and machine-readable Moderate: clarifies page context
FAQ dropdowns FAQPage Entity has structured knowledge to share High: expands SERP real estate significantly
Star ratings AggregateRating, Review Entity has customer validation Very high: visual trust signal
Product details Product, Offer Entity sells identifiable products with pricing High: price and availability shown
Organization info Organization, LocalBusiness Entity is recognized as a structured business Moderate: logo and info in results
HowTo steps HowTo Entity provides structured instructional content High: step-by-step display in results
Sitelinks Navigation + authority signals Google trusts your site structure enough to show sub-links Very high: dominates SERP position

Monitoring in Search Console

Google Search Console tracks structured data health across your entire site continuously through the Enhancements report. This report monitors every schema type Google detects and flags when something breaks.

Errors vs. Warnings

Understanding the difference is critical:

Common error causes: missing required fields (like "name" or "image" for Product schema), incorrect data types (string where a number is expected), URLs that do not resolve, and nesting errors in JSON-LD.

Manual Rich Result Verification

The Enhancements report tells you whether schema is valid. It does not guarantee that Google will display rich results for every valid page. Google makes editorial decisions about when to show rich results based on query context, competition, and other factors.

To verify actual display, manually search for your key pages:

  1. Search the exact page title or a query the page should rank for.
  2. Check the search result: does it show any rich result features?
  3. Compare to what you expect based on your schema implementation.
  4. If schema is valid but rich results do not appear, the page may not rank high enough or Google may not consider the rich result appropriate for the query.

The September 2025 Schema Changes

In September 2025, Google removed support for six schema types in Search Console reporting: Course Info, Claim Review, Estimated Salary, Learning Video, Special Announcement, and Vehicle Listing. If your site uses any of these types, they no longer appear in the Enhancements report and no longer generate rich results.

This is a reminder that schema support is not permanent. Google adds and removes rich result types based on utility and usage. Monitoring for changes in the Enhancements report catches these shifts before they create extended gaps in your SERP presentation.

Loss of rich results is an early warning signal. Before traffic drops, before rankings fall, rich results disappear. This makes the Enhancements report a leading indicator of entity signal health.

Validation Tools

Tool Purpose When to Use
Google Rich Results Test Test if a page can generate rich results After implementing or changing schema on a page
Schema Markup Validator Validate JSON-LD syntax against schema.org During development, before deployment
GSC Enhancements report Site-wide schema health monitoring Monthly review, after schema changes

Assignment

Audit your rich results across your site:

  1. Check the GSC Enhancements report. For each schema type, note: valid items, warnings, and errors.
  2. Fix every error immediately. Errors prevent rich results entirely.
  3. Manually search for 10 of your key pages by title. For each, note whether any rich result features appear.
  4. Run any page with schema through the Rich Results Test. Confirm it passes validation.
  5. Compare your current rich result count to three months ago (if data is available). Is the count stable, growing, or declining?
