Crawl & render with the Fetch as Google tool
Learn about Fetch as Google
Fetch as Google is a diagnostic tool that allows you to simulate how Google crawls or renders a URL on your site.
The Fetch as Google tool has two modes of operation that you can use to test Google crawling and rendering for URL on your site:
When the Fetch as Google tool is in fetch mode, Googlebot crawls any URL that corresponds to the path that you requested. If Googlebot is able to successfully crawl your requested URL, you can review the response your site sent to Googlebot. This is a relatively quick, low-level operation that you can use to check or debug suspected network connectivity or security issues with your site.
