Google Search Console (formerly Google Webmaster Tools) is a free tool from Google. It helps to optimise websites and plays a key role in their positioning. It allows you to monitor your own websites in Google searches.
GSC will help you check:
- Whether your site is indexed correctly.
- Data on your website's search traffic, e.g. how often your website appears in Google searches, which keywords it appears for, etc.
- What links lead to your website
