Prompt
I need a complete SEO diagnostic report for our B2B SaaS platform's website and technical blog. Walk me through a comprehensive audit that evaluates crawlability, indexation status, performance metrics, header and title tagging, meta details, and E-E-A-T content depth. Organize your response into an executive summary, segmented technical findings, on-page review sections, and content assessment sections. Make sure each identified defect includes the specific problem, estimated impact, observed evidence, exact remediation steps, and priority level. Conclude with a clear action plan broken into urgent fixes, high-leverage updates, quick wins, and long-range strategies.
