Google Search Console
Free Google tool for monitoring a site's visibility in the Google index — performance reports, index coverage, Core Web Vitals data, and URL inspection. A mandatory SEO tool.
Google Search Console — explained in more detail
Google Search Console (GSC) is the official interface between a site owner and the Google index. Core features: Performance (clicks, impressions, CTR, position per query and URL — up to 16 months of history), Index Coverage (which URLs are indexed, which are blocked/errored), URL Inspection (check the crawl status of individual URLs and request indexing), Core Web Vitals, Sitemaps.
GSC provides the only authoritative data on Google visibility. Third-party tools (Ahrefs, Semrush) estimate volume and position from their own crawls — GSC shows what actually happened in the SERPs. The GSC API allows automated data exports, making it useful for recurring reports and AI-driven analysis.
Example / In practice
A site loses visibility after a core update. Instead of speculating, you check GSC: which queries and URLs are affected? What position shifts occurred? Which clusters stayed stable? That yields a grounded recovery hypothesis — without GSC, it’s guesswork.
