Google Docs: Is there any way to tell if people have opened a document that you have shared on Google Docs?

Question

I sent out links (read-only) to a number of people and am curious if there is a way to see whether people are actually going out and viewing that document.

I understand it likely won't have names for everyone/anyone that looks at it, but I'd be interested at least in knowing how many "hits" it got to make sure that at least some of those I sent it too actually looked at it.

Answer 1

This page describes a method to do so.

It suggests to add a blank image to the document which can then be counted using statcounter.com
