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:
- 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. - 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. - Separate technical crawl/index findings from content quality and authority. Do not invent ranking-factor weights or promise ranking changes.
- 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.
