Schema is the new backlink

In the link era, you optimised for the graph between domains. In the citation era, you optimise for the graph between entities. Schema.org markup is how you declare that graph to the engines that build the answer layer.

A Citable Packet is the minimum viable unit: a chunk of expertise with enough structured metadata that an AI agent can quote it without ambiguity about who said it, when, and on what grounds.

Verified Citable Insight

"If a model can re-emit your claim with attribution intact and zero loss of meaning, you have a Citable Packet. If it cannot, you have content."
