// FEATURED EXTRACT

Multi-domain @graph — the 3-rule system

Rule 1. Each domain's Organization entity uses a stable @id matching its canonical URL plus #org. Example: https://seoagencybangkok.com/#org.

Rule 2. Cross-references use subjectOf or knowsAbout with the partner's @id. Don't use sameAs for sister-brand links — that signals "same entity, different URL" which Google demotes as duplicate.

Rule 3. The Person entity for the founder is shared across all sites with the same @id. This is correct: it's literally the same person. Do this and the AI assistants build the right mental model.

We deployed this pattern across our 4-site network in March 2026. AEO citation rate for the cluster increased 3.4x within 7 weeks.
