How do I keep Google from indexing documents I share?
You don't need to do anything
Every document you share on Clarify-it.com includes a header that tells Google and other search engines not to add your page to their indexes. In addition, no services are notified when you create a new document.
The only way for someone to view your document is for you to give them the unique, random url that is generated when you create your document.
Can I password protect a document?
No. But unless you send the url for your document to them they will not be able to access it.
