Google Search Console (GSC)

Google Search Console is a free tool from Google that shows how your site is doing in search. It reports the queries you appear for, your clicks, impressions, average position, and CTR, plus which pages are indexed and any technical issues Google found. It is first-party data straight from the source, unlike third-party estimates.

Live in the Performance report to find queries where you rank on page two (quick-win opportunities), pages with high impressions but low CTR (title and snippet fixes), and rising or falling trends by query and page. Use the Pages report to diagnose indexation problems, URL Inspection to check individual pages, and the enhancement reports for structured-data and Core Web Vitals issues. It is the primary diagnostic tool in SEO.

Senior practitioners treat GSC as ground truth and build reporting and monitoring around it, exporting via the API to get past the 1,000-row UI cap and to track query-cluster trends over time. They cross-reference its indexation data with crawl and log-file analysis for a full technical picture, and they know its quirks — sampling, data delays, the way AI Overviews inflate impressions — so they interpret rather than take it literally.
