Read-only SEO HTTP audit with saved evidence

What it does

Audits a live site's technical SEO without changing anything.

• Fetches pages, robots.txt and sitemaps (index to child sitemaps, recursively) and saves bodies, headers, redirects, hashes and timestamps
• Extracts title, meta description, canonical, meta robots, X-Robots-Tag, H1s, image alt text and OG images
• Evaluates robots.txt with Google's documented rules (longest match, Allow wins ties) and checks whether images are actually crawlable
• Classifies findings as observed defects, items needing Search Console, or things that are not automatically defects

How to use

python scripts/seo_audit.py https://www.example.com/ --out ./seo-audit

It writes seo-audit/report.json and evidence/. The agent then reports priorities, target URLs, evidence and remedies, citing Google's official documentation.

Requirements

• Python 3 (standard library only)

Notes

• No publishing, CMS edits, Search Console registration or URL submission during the audit.
• Indexing and ranking are never judged without Search Console data.
• Keep concurrency and delays conservative to avoid loading the target site.
