The most important Technical SEO metrics include crawl errors, index coverage, Core Web Vitals (LCP, INP, CLS), page speed, mobile usability, broken links, duplicate content, and structured data issues, as these directly affect how well search engines can access and rank a website. When reporting to stakeholders or clients, these findings are usually simplified by grouping issues into priority levels (critical, high, medium, low) and explaining their impact on rankings, user experience, and traffic potential, often supported with visual trends and clear action steps so that both technical teams and non-technical stakeholders can easily understand what needs improvement and why it matters.
