How do you build notability for a Wikipedia page over time?

Building notability is a project measured in months and quarters rather than weeks. The work is to assemble a body of substantive third-party coverage in the reliable-source category that establishes the subject’s encyclopedic importance. The cadence matters: a single piece in a top outlet does not establish sustained notability; the community looks for coverage that runs over time and across outlets. Recognition from independent bodies (analyst rankings, awards from established institutions, inclusion in authoritative reference works) contributes where it is editorially generated rather than self-submitted. The work intersects with PR strategy but it is not the same work: notability requires substantive treatment of the subject, which means coverage that goes beyond announcement and quotes into actual analysis and reporting. Twelve to eighteen months is the planning baseline for borderline subjects, often longer for subjects who start without a meaningful source base.
