Google webmaster is a tool used for indexing and also allows you to communicate with Google and adjust many aspects of how Google sees your site, such as list the external and internal links to your site, adjust the crawl rate at which Google bot indexes your site, check the keywords users typed to land on your site, as well as the click through rate for each keyword, see your site's statistics, and many more.

Google Webmaster Console is like your own Hubble Telescope inside the Google Galaxy: it allows you to see how your site interact with Google, how many pages have been indexed, how your data is processed.
It's a diagnostic tool which is vital to properly know, because Seo is 50% technical issues and 50% understanding what people want.
