Can topic clusters work without Schema.org markup?

Internal linking creates human-navigable clusters, but AI agents require machine-readable relationships. Without Schema.org about/subjectOf properties, clusters are invisible to LLMs, AI Overviews, and agentic search systems. Traditional topic clusters rely on anchor text and URL patterns—semantic clusters use explicit entity relationships that AI can verify and traverse.
