This is pretty scary if you are not careful.
Google will soon allow search engines to crawl and index Google Apps Documents, Spreadsheets, and Presentations that are published on Google Apps.
Yes, YOUR Google Apps.
This only applies to files explicitly published using the "publish as web page" or "publish/embed" options and linked to a public webpage.
This does not apply to files shared via the "Allow anyone with the link to view (no sign-in required)" option.`
If you don’t want your publicly-published documents crawled by the Google spiders, you can de-publish them
According to Google,
"We will be launching a change for published docs. The change will allow published docs that are linked to from a public website to be crawled and indexed, which means they can appear in search results you see on Google.com and other search engines."
Currently, the Google Apps master view does not indicate which documents (Documents, Spreadsheets, and Presentations) are publicly published
I have a lot of data in Spreadsheets that dynamically change onto a public web page.
I better start cleaning up my files and checking file permissions.
Just what I need on a Monday morning…
