GUIDE / DATA

Publish structured data that matches the page

Markup helps systems interpret a page when it describes exactly what readers can verify there.

01 / GUIDE / DATA

Start with visible content

List facts actually shown: title, author, date, image, organization, references and page relationships. Then select a relevant schema.org type. JSON-LD cannot add invisible promises or guarantee visibility in search or assistants.

IN PRACTICE

A correction is complete when its consequences have been reviewed

A page belongs to a system: summary, title, tables, links, language versions and structured data. Correcting a sentence requires finding where it is reused and checking that each version still tells the same story.

Which check comes first?

Choose the situation you observed. Each path gives a first check, useful evidence and the limit of that check.

Two pages give incompatible information

First check
Isolate the same claim on both pages and compare source, effective date and scope. Name the reference page and decision owner before propagating a correction.
Evidence to retain
Both URLs, exact wording, references, effective date, decision and pages or snippets repeating the information.
Limit to remember
The newest page is not necessarily correct. Changing a publication date does not resolve different definitions or missing evidence.

  1. Identify

    Which claims depend on the change?

  2. Propagate

    Which pages and languages reuse them?

  3. Review

    Do numbers, links and limits agree everywhere?

Final check

An update date marks a real edit. It does not redefine source or observation dates. Keep those roles separate in prose and references.

02 / GUIDE / DATA

Five consistency checks

Each property needs a visible source, an exact value and an owner for updates.

01

Relevant type

Choose a type suited to the page and to features actually documented by the search provider.

Record to retain · Type and rationale
02

Visible parity

Align titles, dates, author, image and descriptions with public content; avoid unseen awards or reviews.

Record to retain · Field and visible element
03

Stable identity

Use canonical URLs and stable @id values to connect page, article, person and organization without conflating them.

Record to retain · URL and identifier
04

Dates and versions

Separate original publication from a substantial modification. A minor edit does not justify claiming a major revision.

Record to retain · Verifiable dates
05

Validation and monitoring

Check syntax, required properties, rendered HTML and search reports after changes.

03 / GUIDE / DATA

Four control steps

Markup follows editorial publication and remains testable after updates. Validate syntax and agreement with the page separately: readable JSON does not establish that authors, dates or relationships are correct. After a correction, compare marked-up values with visible content and open the URLs identifying entities.

  1. 01

    Inventory

    List visible information and where it appears on the page.

  2. 02

    Model

    Choose useful types and relationships; omit unjustified properties.

  3. 03

    Validate

    Test JSON-LD and compare values with each language version.

  4. 04

    Maintain

    Recheck dates, images, links and identifiers after content changes.

04 / GUIDE / DATA

Where divergence appears

Common errors arise when page, metadata and reality drift apart.

01

An entity profile changes

Update name, URL, relationships and sources together; do not merge namesakes.

02

A translated article retains stale data

Check title, language, date, image and canonical URL for every variant.

03

No rich result appears

Check eligibility, quality and guidelines first; valid markup never guarantees display.

06 / FAQ

Markup questions

Does JSON-LD guarantee an AI citation?

No. Google AI features rely on search fundamentals; no special markup guarantees a citation.

Can invisible facts be added?

Markup should represent relevant visible content. Add verified, useful facts to the page first.

Must every page be marked up?

Choose types useful for each page. Exhaustive properties create maintenance without improving content.

How should the same entity be linked across several pages?

Use a stable identifier for the intended entity and distinguish it from pages describing it. Check names, roles and source links. A shared logo or similar name does not justify merging organisations or inventing a relationship between them.

07 / Discuss a context

Describe what can be checked

Modest, dated markup tied to public content makes review and maintenance easier.

DEEPER READING / PRACTICE

Describe what the page allows to check

Metadata describes an organisation, article or service. Its value depends on agreement with visible content, identifiers and information that is kept up to date.

Updated on .

Priority checks

Compare each important property to its equivalent on the page. Check names, URLs, dates, authors and references, and then check the consistency of the objects linked to each other.

Interpretation pitfalls

A valid syntax does not prove the accuracy of the data. Adding an attribute to make a presentation more attractive can create a statement that the content does not support.

Working record to retain

A inventory connects object, property, value and visible proof. Identity or date changes trigger a review of the pages that reuse the same information.

PRACTICAL CASE / WORKED EXAMPLE

An old date remains in the metadata

The example is a web control educational situation. It connects the defect to a concrete path and describes a way to verify the correction, rather than consider the only publication of the change as a proof of resolution.

Example context

The content of an article is revised, but the structured data retains an old description and an incoherent date. The different representations of the page differ.

Suggested approach

Compare visible content, labelling and shared references. Identify values from a template or data file. Fix the common sources and then check the objects concerned.

Conclusion and next step

The page and its metadata describe the same editorial status. The control retains the modified values and their justification, without adding property not supported by the content.

Questions for deeper practice

Should we copy all the content in the label?

The goal is a consistent description of the relevant elements. Each selected property should correspond to verifiable information that is kept up to date, rather than exhaustive duplication or an additional promise.

DETAILED WORKSHOP / APPLICATION

Relate declared properties to their visible evidence

  1. 01 / Prepare the necessary information

    Assemble the labelling, page content and reference information. Identify properties that describe identity, dates, author or relationship between objects.

  2. 02 / Carry out the approach

    For each property, find the corresponding information and check its consistency. Examine the values shared between pages. Reduce or correct claims whose content does not provide the expected support.

  3. 03 / Examine an alternative situation

    If a property is optional and its meaning is misestablished, do not fill it with deduction. The quality of the description depends on its relevance and accuracy.

  4. 04 / Decide on the next step

    The labelling is controlled when syntax and values are examined separately. A technical validation should not end the verification of the declared information.

  5. 05 / Hand over the verification records

    Transmit the inventory property, value and visible source. Identity or content changes trigger the review of the templates that reuse this information.

ANNOTATED WORKING DOCUMENT / REVIEW GRID

A inventory of properties related to visible content

The inventory combines object, property, value and proof of page. It identifies the shared information and dependencies that must be reviewed when a change of identity or content.

On a small screen, scroll the grid horizontally to read all three columns.

Example situations to assess
ObservationSupported interpretationNext step
The property corresponds to visible information that is kept up to date.The statement is consistent for the subject and page concerned.Keep the relationship and control its reuse on other pages.
The syntax is valid but the value is old.The labelling may describe a different state of content from the published content.Fix the source of data and check the dependent occurrences.
A property adds a non-supported statement.The description exceeds what the reader can check.Remove or reformulate the value before continuing the technical validation.

Reviewing the working document

The final verification should be processed syntax and background separately. A facultative attribute does not need to be informed when its significance or documentary support is not sufficiently established.

REPORTING / EXAMPLE WORDING

Presentation of results: Describe what the page allows to check

Point to clarify

A declared property must remain supported by the information actually published.

Before handing over

Examine the conformity of the background and technical validity as two additional checks.

Example of a qualified conclusion

The controlled properties correspond to the objects and visible contents indicated. Uncertain or unsustained values have been removed or left to be specified.
