What data do I need to provide for a forensic investigation?

Ideally, you should have access to Google Search Console (GSC), web analytics like GA4, server or CDN logs, and recent deployment/change logs.

Does it help with technical SEO regressions?

Yes, it specifically checks for technical failures such as robots.txt changes, noindex tag injections, broken redirect chains, and server availability issues.

When should I use the SEO Forensic skill instead of a regular audit?

Use this skill during 'incident' scenarios where you see a sudden, significant drop in metrics. Use a standard SEO audit skill for routine health checks or opportunity identification.

Can this skill identify Google Core Update impacts?

Yes, it includes a specific classification framework for algorithm updates, helping you determine if a drop coincides with known Google update dates and which content clusters were affected.
