Google Search Console is a free web service that gives website owners and administrators detailed insights into how their site is performing in Google Search. This includes information on the number of impressions and clicks your site gets in Google search results, as well as the average position of your site for certain queries. Google Search Console also allows you to submit your sitemap to Google, so that they can index your pages more effectively. Finally, GSC provides data on any crawl errors that Google encounters when trying to access your site.
