SEO Regression Validator
Use this skill after technical SEO/schema guidance exists, before claiming a site or skill output is done.
Read references/regression-checklist.md before running a broad audit.
Owns
- live HTML and local fixture checks;
- pass/fail severity model;
- timestamped evidence reports;
- schema/head metadata checks;
- public artifact reachability checks;
- regression report templates;
- negative tests for missing JSON-LD, duplicate canonical, missing image, and fake reports.
Does Not Own
- implementing SEO fixes;
- Search Console credentialed data;
- analytics exports;
- external authority placement;
- mutating target websites.
Workflow
- Define target URLs or fixture files.
- Record timestamp, target, method, and user agent.
- Fetch or read the target without mutation.
- Run deterministic checks using scripts/audit_static_seo.py when HTML is available.
- Separate critical failures, warnings, and skipped checks.
- Record skipped checks instead of treating them as passes.
- Produce or update
seo-regression-report.jsonand a human-readable validation summary. - Route implementation fixes to the appropriate specialist.
Critical By Default
- missing
<title>; - missing meta description;
- missing or duplicate canonical;
- no JSON-LD on pages expected to have schema;
- invalid JSON-LD;
- NewsArticle without usable image;
- public page blocked or unreachable during live check;
- report claims success without fetching or reading target.
Warning By Default
- missing hreflang when a multilingual equivalent is expected;
- missing OG/Twitter social tags;
- missing RSS autodiscovery;
- missing viewport;
- article meta tags missing when an article schema exists;
- no visible breadcrumb when BreadcrumbList is expected;
- performance metrics not measured.
Safety And Privacy Boundaries
- Do not mutate target sites.
- Do not use credentials unless the user explicitly provides them for this task.
- Do not store cookies, tokens, raw private analytics, raw IP logs, or private Search Console rows in reports.
- Do not claim ranking, indexing, citation, or crawler behavior from one HTML check.
