Google Search Console: Your SEO Foundation
Google Search Console is the most important free SEO tool. It shows how Google sees your site: which pages are indexed, what queries trigger impressions, your average position for each keyword, and any crawl errors or manual actions. No other tool provides this direct communication channel with Google.
Check Search Console weekly. Review the Performance report for ranking changes, the Pages report for indexing issues, and the Enhancements report for Core Web Vitals and mobile usability. Set up email alerts for critical issues.
PageSpeed Insights and Core Web Vitals
PageSpeed Insights measures your page performance using real user data from Chrome UX Report and lab data from Lighthouse. It reports LCP, INP, and CLS scores with specific optimization recommendations. Test your most important pages monthly.
Our page speed checker provides complementary performance analysis with additional metrics and recommendations. Use both tools for comprehensive performance monitoring.
Rich Results Test and Schema Validation
The Rich Results Test validates your structured data implementation. Paste a URL or code snippet to see which rich results Google can generate from your schema markup. It identifies errors and warnings that prevent rich result eligibility.
Our structured data checker provides deeper analysis, checking all schema types on a page and validating against Google requirements. Run it after any schema changes to catch issues before they affect search appearance.
