Use structured data only for actually visible content
Structured data must not provide any information other than that contained in the page itself. Visibility, recency, and consistency are checked.
For SEO teams and developers, "Binding Markup to Visible Content" illustrates the difference between "Same Factual Basis" and "Relevant Page Content." "Invisible Offering" is the typical warning sign.

Why must structured data match the visible page content?
Every distinguished entity and essential attribute needs a visible or easily accessible counterpart on the same page. A common data source keeps names, prices, availability, dates, and ratings synchronized; conditional fields disappear from both displays simultaneously.
Invisible Offer
Invisible Offer JSON-LD contains price or availability, even though the page doesn't display this condition or presents it differently to users.
Outdated Entity – A central markup cache retains old opening hours, authors, or product values after the visible update.
Global External Information Footer data is output as the primary entity of each subpage, even though its actual subject is something else.
Working Example: "Invisible Offer"

Synchronous State
Proportion of structured core values with a clear visible correspondence and a shared, responsible data source.
Number of conflicting or orphaned markup entries per page type after content changes and releases.
Relevant Page Content
Map all entities and essential properties of a template to their visible page element and data field.
Implement common sources and conditions and automatically compare the rendered view against the final JSON-LD.
Monitor discrepancies in content maintenance and releases and do not output unassigned properties until clarified.
Same Factual Basis
Test criterion
Same Factual Basis
Markup and visible view retrieve name, value, status, and time from the same responsible source.
Test criterion
Relevant Page Content
The marked-up entity is the subject of the page and not merely mentioned in navigation, a hidden tab, or the global footer.
Synchronous State – Changing, expiring, or removing a visible value updates the structured output in the same publishing process.
