SEO optimization

Search engine optimization based on Lighthouse SEO audits and Google Search guidelines. Focus on technical SEO, on-page optimization, and structured data.

Evidence-led audit workflow

When a rendered page is available:

1. Run live Lighthouse SEO and Agentic Browsing checks when that capability is available; with Chrome DevTools MCP, use lighthouse_audit. Use the results to localize rendered-page failures.
2. Inspect signals Lighthouse cannot establish on its own: response headers, redirects, robots.txt, sitemap coverage, canonical consistency across page templates, structured-data eligibility, and Search Console evidence when the user provides access.
3. Separate technical crawl/index findings from content quality and authority. Do not invent ranking-factor weights or promise ranking changes.
4. Fix the source and re-run the same checks. For indexation or ranking outcomes, report that search-engine validation remains pending.

If live tools are unavailable, use category-specific Lighthouse CLI output plus direct source and HTTP inspection. A Lighthouse SEO score covers a useful subset of technical checks; it is not a prediction of rankings.

Area	What this skill can verify
Crawl and index controls	Technical configuration and consistency
Rendered metadata and semantics	Presence, validity, and page-template issues
Structured data	Syntax and eligibility signals, not guaranteed rich results
Core Web Vitals	Link to measured field/lab evidence from the Core Web Vitals skill
Content usefulness and authority	Review quality, but do not assign synthetic ranking percentages
