While Organization schemas appear 100% unique (different @id per page), the actual content is only 37.5% unique. The name "MA 10 - Informationsplattform" appears on 35 different pages!
What's Actually IN the Organization Schema?
Here's a real Organization schema from a kindergarten page:
âś“ Fields Present
- @context (always same)
- @type (always "Organization")
- @id (unique URL-based ID)
- dateModified
- datePublished
- inLanguage (always "de-DE")
- name (the ONLY useful info!)
âś— Fields Missing
- address
- telephone
- contactPoint
- description
- openingHours
- areaServed
- parentOrganization
Uniqueness Analysis Per Schema Type
Comparing FULL schema (with @id/dates) vs CONTENT only (without metadata):
| Schema Type | Total | Unique (Full) | Unique (Content) | Verdict |
|---|---|---|---|---|
| Organization | 176 | 176 (100%) | 66 (37.5%) | PSEUDO-UNIQUE |
| WebPage | 114 | 114 (100%) | 114 (100%) | TRULY UNIQUE |
| CollectionPage | 18 | 18 (100%) | 18 (100%) | TRULY UNIQUE |
| Preschool | 35 | 35 (100%) | 35 (100%) | TRULY UNIQUE |
| Project | 11 | 11 (100%) | 11 (100%) | TRULY UNIQUE |
| NewsArticle | 7 | 7 (100%) | 7 (100%) | TRULY UNIQUE |
| Event | 6 | 6 (100%) | 6 (100%) | TRULY UNIQUE |
Most Repeated Organization Content
These organization names appear on MULTIPLE pages with identical content:
| Organization Name | Occurrences | % of Total | Meaning |
|---|---|---|---|
| "MA 10 - Informationsplattform" | 35 | 19.9% | Magistratsabteilung 10 - Wiener Kindergärten |
| "MA 21" | 13 | 7.4% | Stadtteilplanung und Flächennutzung |
| "MA 10" | 7 | 4.0% | Wiener Kindergärten |
| "MA 08" | 2 | 1.1% | Wiener Stadt- und Landesarchiv |
| "MA 53" | 2 | 1.1% | Presse- und Informationsdienst |
35 different kindergarten pages all have the EXACT SAME Organization schema content: "name": "MA 10 - Informationsplattform"
They only differ by @id and dates - which is metadata, not meaningful content!
What AI/LLMs Can Extract
From Schema.org âś“
- Page title (name)
- Page description
- Last updated date
- Language (German)
- Organization abbreviation ("MA 10")
NOT from Schema.org âś—
- Full organization name
- Contact phone number
- Email address
- Physical address
- Opening hours
- Service descriptions
- Department hierarchy
Bottom line: An LLM reading "MA 10 - Informationsplattform" cannot know this means "Wiener Kindergärten" (Vienna Kindergartens) without external knowledge.

Recommendations for GEO Optimization
1. Enrich Organization Schema

Each kindergarten page should have its own ContactPoint with specific phone/email.
3. Use GovernmentService Schema
For service pages, use schema.org/GovernmentService with service descriptions.

Conclusion
Organization schema on wien.gv.at is PSEUDO-UNIQUE.
It looks different per page (unique @id and dates), but the actual meaningful content (just the "name" field with cryptic abbreviations like "MA 10") is repeated across many pages.
For AI/GEO: The schema provides basic page identification but lacks the rich organizational data (contacts, addresses, services) that would make it truly valuable for LLMs.
