Google Search Console is a wonderful way to understand search engine issues and optimize your site for Google. “Fetch as Google” is an option available for webmasters to check how a web page will look when Googlebot crawls that page.
The Fetch as Google tool enables you to test how Google crawls or renders a URL on your site. You can use Fetch as Google to see whether Googlebot can access a page on your site, how it renders the page, and whether any page resources (such as images or scripts) are blocked to Googlebot.
