Google Webmaster Tools Fetch and Render tool Includes a Submit to Index Feature for "Critical Cases"


Per SE Roundtable, there's an interesting recap of a thread John Mueller was involved in where he discussed the uses cases for the Submit to Index feature of the Fetch and Render tool in GWMT.

For sites that have made changes to particular pages or directories, but Google is not crawling them quickly enough, this seems to be an interesting option to get those changes reflected more quickly. I think this might work particularly well for sites that were suffering from duplicate and/or thin content but have made the necessary changes to the pages and their crawl "budget" is limited.

Has anyone used Submit to Index in cases similar to above? Thoughts?
