Google Search Console is a free service offered by Google that helps you monitor, maintain, and troubleshoot your site's presence in Google Search results. You don't have to sign up for Search Console to be included in Google Search results, but Search Console helps you understand and improve how Google sees your site.

Google Webmaster Tools (GSC) concentrates on the technical aspects of a website. It offers insights into how Google's search engine views your site, highlighting issues like crawl errors, sitemap submissions, and mobile usability. It also provides data on search queries leading to your site.
