Google Search Console (previously known as Google Webmaster Tools) is a free tool by Google. Among all of its other features, it lets you understand better how people are finding your website through Google’s Search Engine. It displays keywords, their volume, click-through rate, etc. But in order to get access to such data, you need to verify the ownership of that particular website. In 2013, Google added another way to verify the site ownership in Google Search Console with Google Tag Manager.
