What the Audit Prioritizes

Improved machine readabilityRich-result potentialClearer entitiesStronger trust context

Test area: Structured data.

A JSON-LD block contains invalid JSON

Illustrative values, not customer findings. Existing audit-check X114b: JSON-LD is parsebar.

Example URL: https://example.org/produkt
Observed value: jsonld_parse_errors = 1, for example by a superfluous comma.
Expectation in the check: jsonld_parse_errors = 0.
When the statement applies: The rule checks existing JSON-LD blocks. Missing markup is another question and must not be called a parse error.
Limit of the statement: Parsebares JSON does not yet confirm suitable types, complete characteristics or truthful prices.

Why this area is important

Structured data helps search engines understand page types, entities, and relationships more clearly. They are an important link between classic SEO, rich results and AI readiness.

Risk without testing

Faulty, inappropriate or excessive markup can cost trust and weaken the chances of advanced search results. It is especially critical if JSON-LD does not fit the visible content.

For whom particularly relevant

Especially important for shops, local providers, organizations, events, guides, FAQ pages, breadcrumb structures and websites with clear products, locations or services.

Typical findings in the audit

JSON-LD contains syntax errors or invalid mandatory fields
Schema types do not match the visible page type
Product, LocalBusiness or Breadcrumb data is incomplete
several markup blocks contradict each other or are missing on important templates

Recommended implementation

Use only suitable schema types for real content
Check JSON-LD against visible content, URL, title and breadcrumb
Maintain mandatory and recommended fields per page type
Test Markup template-based and re-crawl after changes

From Diagnosis to Implementation

Unlocked audits show not only the area, but the affected URLs, examples and priorities. This makes it visible which errors belong first in development, editing, data protection or consulting.

Frequent Questions: Structured Data

The most important classifications before starting an analysis.

Do Structured Data Guarantee Rich Results?

No. They increase technical suitability, but do not guarantee representation. Google decides depending on quality, search query, guidelines and page.

Why does Seitenreport check the visible content reference?

Structured data should describe what users actually see on the page. The matching prevents over-optimized or misleading markup.
