Schema markup helps Google knowledge panels and AI search engines (Perplexity, ChatGPT, Gemini, AI Overviews) extract memberships and surface them in answers — the same discipline applied to credentials at [[rule-gold-seal-use-schema-org-person-hascredential]].\n3. **A dedicated page is what procurement leads and architects look for** when pre-qualifying a firm — the same logic as the Gold Seal `/credentials` page at [[rule-gold-seal-dedicated-credentials-page]].\n\n**How to apply:**\n\n- Single page, link from global footer (under *\"About\"*) and from team-bio mentions of credentials.\n- **Update every January** after annual membership renewal.\n- Validate every JSON-LD block with the **Schema Markup Validator** (validator.schema.org) before deploy.\n- For RenoMark specifically, also implement [[rule-renomark-dedicated-page-with-certificate-image]] — the dedicated `/renomark` page lives alongside `/affiliations`, not inside it.","rationale_body":null,"metadata":null,"links":{"outgoing":[{"slug":"rule-renomark-dedicated-page-with-certificate-image","title":"Rule (renovator client sites): build a dedicated `/renomark` page with the verbatim 10-point Code and the current-year certificate image","kind":"rule","scope":"business","link_type":"relates-to"},{"slug":"rule-gold-seal-dedicated-credentials-page","title":"Rule (Tier-2 ICI GC sites): build a single dedicated /credentials page listing every team credential (P.Eng., GSC, P.GSC, PMP, CET, LEED AP, Red Seal, COR, CHSC) with brief descriptions, no puffery","kind":"rule","scope":"business","link_type":"relates-to"},{"slug":"rule-gold-seal-use-schema-org-person-hascredential","title":"Rule (Tier-2 ICI GC sites): use schema.org Person + hasCredential + EducationalOccupationalCredential markup so Gold Seal credentials surface in Google knowledge panels and AI overviews","kind":"rule","scope":"business","link_type":"relates-to"},{"slug":"hba-site-display-pattern-a-vs-pattern-b","title":"Two HBA display patterns across Ontario builder/renovator sites: Pattern A (small custom + renovation firms show HBA + RenoMark prominently in footer); Pattern B (large production builders rarely show HBA logos, lead with HCRA + Tarion)","kind":"reference","scope":"business","link_type":"depends-on"}],"incoming":[{"slug":"research-brief-canadian-hba-stack","title":"Research brief: The Canadian HBA stack — CHBA / OHBA / BILD / WRHBA federated three-tier model, with marketing implications for Ontario builders and renovators (May 24, 2026)","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"hba-site-display-pattern-a-vs-pattern-b","title":"Two HBA display patterns across Ontario builder/renovator sites: Pattern A (small custom + renovation firms show HBA + RenoMark prominently in footer); Pattern B (large production builders rarely show HBA logos, lead with HCRA + Tarion)","kind":"reference","scope":"business","link_type":"relates-to"},{"slug":"schema-markup-for-contractor-sites-2026-google-guidance","title":"Schema markup for contractor sites (2026 Google guidance): GeneralContractor / HomeAndConstructionBusiness / LocalBusiness, Service per service-line, Review + AggregateRating, Person for principals, FAQPage on service pages, Project (Article subtype) on case studies","kind":"reference","scope":"business","link_type":"relates-to"}]},"created_at":"2026-05-24T16:32:33.850Z","updated_at":"2026-05-24T16:32:33.850Z"}
