You are running the post-deploy SEO regression check. A new deployment to production has just completed. Your goal is to confirm that no SEO signals were degraded by this release.
## Context
The deployment was triggered on the `main` branch. Pull the deployed URL from the environment or deployment payload. If multiple URLs are available (preview vs. production), always check the production domain.
## Steps
1. **Define the pages to check.** Use the following priority list:
- Homepage (`/`)
- Top 5 pages by organic traffic (refer to the tracked list in the repo or use GSC data if available)
- Any pages modified in the most recent deploy (inspect the git diff or deployment manifest for changed routes)
2. **Scan each page** using `scan_page`. Collect: HTTP status code, canonical URL, title tag, meta description, and any schema/structured data blocks.
3. **Deep-check each page** using `get_page_seo`. Compare the following against the known-good baseline (last successful deploy):
- Title tag: text, length (50–60 chars ideal), keyword presence
- Meta description: text, length (120–158 chars ideal), not missing
- Canonical URL: must be self-referencing and use the production domain (not a staging URL)
- Open Graph tags: `og:title`, `og:description`, `og:image` must be present
- Structured data: type and `@id` must match pre-deploy values; no `null` or empty fields
- Robots meta: must not be `noindex` on publicly intended pages
4. **Flag regressions.** A regression is any change from the previous deploy that worsens SEO signals. Examples: title changed without a release note, canonical pointing to a wrong domain, structured data removed, page newly marked `noindex`.
5. **Check redirect integrity.** For any known redirect rules (301/302), verify they still resolve correctly and do not chain more than 2 hops.
## Output Format
### Deploy Info
- Deploy timestamp
- Git SHA or deploy ID
- Production URL checked
### SEO Health: PASS / FAIL
### Regressions Found
If none: "No regressions detected."
If any: numbered list — Page URL | Signal | Before | After | Severity
### Warnings
Non-blocking issues worth noting (e.g., title length borderline, description slightly short).
### Recommended Immediate Actions
If any regressions are CRITICAL (e.g., noindex on homepage, wrong canonical), flag for immediate rollback or hotfix. Otherwise list remediation steps with ticket suggestions.
