"What does Googlebot see when it accesses my page?" is a common question webmasters ask us on our forums and at conferences. Our keywords and HTML suggestions features help you understand the content we're extracting from your site, and any issues we may be running into at crawl and indexing time. However, we realized it was important to provide the ability for users to submit pages on their site and get real-time feedback on what Googlebot sees. This feature will help users a great deal when they re-implement their site with a new technology stack, find out that some of their pages have been hacked, or want to understand why they're not ranking for specific keywords.
