Google Knowledge Graph: Entity isReference Domains

Dataset: 62,202 isReference domains | entities

Proprietary analysis of Google's entity validation patterns across the Knowledge Graph.

The Google leak in May 2024 confirmed that Google explicitly associates people with their profile pages (isReference) and articles they have written (isAuthor).

⚠️ You Can't Use Just ANY Domain!

Out of 1,738,093 domains we monitor, only 62,202 qualify as isReference domains.

3.65%

Only 3.65% of domains earn isReference status from Google. Domain selection is critical.

Wikipedia is NOT Required (or even your best bet)

Wikipedia: 6 million entities
Kalicube Pro: 71 million entities
Knowledge Graph: 50 billion entities

0.012%

Wikipedia covers only 0.012% of the Knowledge Graph. If your entity isn't in that 0.012%, you need to build a Knowledge Panel with ~30 isReference url instead.

Why isReference Domains Control AI Narrative

AI assistants (ChatGPT, Google AI, Microsoft Copilot) rely on three sources - the Algorithmic Trinity(and Kalicube Pro tracks all three for every client !):

1. LLM Memory

Creative but unreliable. Will hallucinate without facts.

2. Knowledge Graph

The trusted encyclopedia. isReference domains are how you get IN.

3. Search Results

Real-time window. Needs KG foundation first.

The bottom line: Without isReference validation → No Knowledge Graph entry → AI assistants hallucinate about your brand. The domains below are your path to entity recognition.

Why This Data Matters

Google validates entity information through patterns of corroborating mentions across trusted domains. This list shows where Google recognizes all entity types - but here's the catch: entity authority is extremely niche-specific.

Entity Validation at Scale

Google's Knowledge Graph requires consistent entity recognition across validated domains.

Only 3.65% of domains (62202 out of 1738093) qualify as isReference
Brands typically need ~30 entity-validated url for a stable Knowledge Panel
Each niche has unique entity authority patterns
Generic "authority lists" miss 95%+ of niche-specific opportunities

⚠️ This Free List is Intentionally Limited

The top 100 domains shown above are dominated by massive generalist sites. For 99% of brands, the real opportunities lie in the niche-specific domains that only appear in our full platform dataset.
