In May 2015, Google updated its webmaster tools formerly known as Google Webmaster Tools to Google Search Console after the company felt the name webmaster was outdated. Google offers a number of resources to tune your site's SEO functions as well as get important information about visitors and their activities while on the site. Generally, the Google Search Console allows you to gain varied insights on your website. 
To access the search console functions, you first need to verify the ownership of the site you intend to analyze. There are five ways of verifying domain name ownership and these are:
• Using Google Analytics
• Use Google tag manager account
• Upload a HTML file
• Sign in to domain name provider
• Add a HTML tag to the head of your site
Once you have completed the verification process, these five functions can be used from the console.
