Technical SEO/GEO Control Plane 2026

Methodology

• Passing these controls does not guarantee rankings, traffic, AI citations, backlinks or market share.
• A failed critical control blocks release or page expansion until corrected.
• Controls prove implementation and governance; business outcomes still require reviewed GSC, AI citation, referral and authority evidence.

Control matrix

Pass criteria and failure response

• SEO/GEO release gate chain

  Pass criteria

  • TypeScript compiles with no emit.
  • Source/template SEO/GEO audits pass before build.
  • Production build completes with the canonical site URL.
  • Rendered artifact and build-performance budget audits pass against .next output.

  Failure response

  • Block release until the failing gate is fixed.
  • Do not publish traffic, ranking, citation or market-share claims from a failed gate.

  The gate proves local controls passed; it does not publish private analytics, raw Search Console exports or server logs.

• Static rendering, canonical and noindex control

  Pass criteria

  • Representative built pages contain canonical URLs and expected schema/citation snippets.
  • Indexable page manifest mirrors sitemap intent.
  • No known thin or disallowed page class is included in the sitemap.

  Failure response

  • Remove affected URLs from sitemap or apply noindex until source-backed value is restored.
  • Fix the rendered artifact, not only the source template.

  Rendered artifacts and manifests are public; crawl impressions and query rows remain local until reviewed aggregate reporting.

• Structured data and citation contract

  Pass criteria

  • Dataset/DataDownload JSON-LD points at canonical JSON endpoints.
  • Calculator and tool pages expose provenance and WebApplication context where applicable.
  • Rendered audit rejects misleading ClaimReview or unsupported guarantee language.

  Failure response

  • Remove unsupported schema before release.
  • Prefer visible source provenance over schema-only trust signals.

  Schema describes public source-backed content only; reviewedBy and sameAs fragments remain blocked unless local evidence workflows approve them.

• Open-data and API discovery control

  Pass criteria

  • PUBLIC_DATASETS count matches the catalog and rendered DataCatalog JSON-LD.
  • OpenAPI includes each dataset route.
  • LLM discovery files include strategic research, API and data endpoints.

  Failure response

  • Do not add a public endpoint without a catalog record and API reference entry.
  • Do not rely on a hidden JSON feed as a citation surface.

  Public endpoints expose reusable metadata and controls; raw outreach, analytics, evidence logs and rejected submissions stay local.

• AI and search crawler access control

  Pass criteria

  • Robots policy is generated from shared crawler allow/deny constants.
  • Crawler-access JSON and report explain live proof limits.
  • MCP and AI-agent surfaces expose read-only provenance-out tooling.

  Failure response

  • Fix robots, middleware or discovery headers before interpreting AI citation or referral metrics.
  • Require server-log evidence for crawler-fetch claims.

  Server logs are local evidence. Public surfaces can publish reviewed aggregate crawler findings only after redaction and scope review.

• Freshness and source-liveness control

  Pass criteria

  • Public freshness report has zero stale and zero invalid dated source records.
  • Major release sign-off can include source liveness checks.
  • Policy and figure-change surfaces keep old/new values, dates and source URLs.

  Failure response

  • Freeze new content expansion for affected cohorts until freshness is restored.
  • Rebase any forecast range that depends on stale high-risk facts.

  Freshness status is public; source-refresh working notes and failed live probes can remain local until triaged.

• Programmatic page quality and pruning control

  Pass criteria

  • Thin fallback combinations are excluded from sitemap and guarded from indexing.
  • Surviving long-tail pages include source-basis blocks and at-a-glance data.
  • Internal links route users and crawlers to stronger data, route and calculator pages.

  Failure response

  • Noindex or remove sparse page classes before adding more programmatic URLs.
  • Prioritise thickening and source provenance over raw URL count.

  Indexability intent is public through sitemap and manifest; GSC URL performance exports stay local.

• Client bundle and interactive-tool performance control

  Pass criteria

  • Root app JS stays within the 380 kB raw / 115 kB gzip post-build budget.
  • Representative route JS stays within the 425 kB raw / 130 kB gzip post-build budget.
  • Named data-heavy HTML and public feed artifacts stay within explicit .next/server/app payload budgets.
  • Calculator pages expose server-rendered context, provenance and worked examples where available.
  • Widgets and tools keep required attribution and source links.

  Failure response

  • Move bulky data and source-backed explanatory content back to server-rendered surfaces.
  • Do not accept client interactivity that hides the answer layer from crawlers.

  Bundle sizes and rendered output are public build evidence; user-entered calculator profiles are never logged or published by these controls.

• Experiment and private evidence boundary control

  Pass criteria

  • Local evidence commands require period, property/search type or bot-filter context where relevant.
  • Public datasets publish protocols and approved aggregate fields, not raw private exports.
  • Outcome claims require reviewed scope-matched evidence rows.

  Failure response

  • Reject unscoped or unredacted evidence from public claims.
  • Treat anecdotal wins as local notes until the aggregate review contract passes.

  Raw GSC, GA4, bot-log, screenshots, transcripts and outreach records stay local unless separately reviewed, redacted and aggregated.
