Question

What appeared for a specified query under specified conditions?

Nodes

Query; SERP snapshot; Result occurrence; URL; Domain; Result feature

Relationship sketch

snapshot → query/context
snapshot → occurrence
occurrence → URL and feature

Evidence inputs

Permitted search observations or licensed data, exact collection context, time, URL and feature details.

Implementation

Model each appearance as an occurrence, not a timeless edge. Distinguish organic results, ads, local results, and AI citations. Compare URL-set overlaps only within documented sampling.

Acceptance checks

Every result belongs to a dated snapshot
Position definition and feature type are retained
Unavailable result data is not represented as zero visibility

Do not infer

Ranking for one query does not make a competitor's schema, word count, or backlink pattern causal.

Publication boundary

Aggregate research may be public; raw collected data obeys permissions.

Source basis
