The most important reports
Performance report: Keywords (search queries), clicks, impressions, CTR, and average position. Filter by date, country, device, and page. The most important report for daily SEO work.
Page indexation: Shows which URLs are indexed and why certain URLs are excluded (noindex, redirect, duplicate, server errors). Essential for indexation monitoring.
Core Web Vitals: Shows LCP, INP, and CLS for mobile and desktop based on real user data (Chrome UX Report). Groups URLs by performance status (Good, Needs improvement, Poor).
URL Inspection: Check individual URLs: Is it indexed? When was it last crawled? Are there any issues? Live test of the current state.
GSC for strategic decisions
Keywords with high impressions but low CTR: Optimize title tags and meta descriptions. Keywords in positions 4-10: Increase content depth for top 3. Pages with indexation issues: Fix technical errors.
