Google said that "in about two weeks, we’ll be launching a change for published Google Docs. The change’ll allow published docs that’re linked to from a public Web site to be crawled and indexed, which means they can appear in search results you see on Google.com and other search engines. This only applies to docs which you explicitly publish using the 'Publish as web page' or 'Publish/embed' option, and which’re linked to from a publicly crawled webpage. This doesn't apply if it's only set to 'Allow anyone with the link to view (no sign-in required)'.  If you don't want your published docs to be crawled, then you can un-publish them by doing the following: -Go to the 'Share tab' -For documents and spreadsheets, choose 'Publish as web page'. For presentations choose 'Publish/embed' -Click on the button that says 'Stop publishing', announced.
