It's time for another experiment!
This time we'll be checking if Google can learn about a new term through a selectively shared post.

Google+ is based on selective sharing principle and only public posts should be indexable. If you share something with only 1, 2 or 100 other people it should still remain inaccessible within Google's index.

What you need to do.
Share this message to a limited number of people (not to public, only those you think would participate in the experiment) and in the custom part (your message) add an imaginary term that you cannot find in Google. (e.g. I just found disaquivalated). Don't mention that phrase anywhere.

And then?
Set up a Google Alert ( for that term and report back here if you get an email.
