The last thing you need to know is that you have control.

If you're not signed in to Google,...
Matt Cutts
...you won't see all the social search goodness.
Matt Cutts
It's important to know that you always have control...
Matt Cutts
...over both your connections and your content.
Matt Cutts
As a user, you can always add or delete links on your Google profile...
Matt Cutts
...just like you can defriend someone on a social networking site.
Matt Cutts
You can also add or block your Google Chat contacts,...
Matt Cutts
...so you won't receive social search results from them.
Matt Cutts
And as a content creator, you can choose what content to make public...
Matt Cutts
...and which public content to be associated with your Google profile.
Matt Cutts
We hope this helps you understand how Google builds your social circle...
...and then, finds useful public information...
Matt Cutts
...from your network of contacts to show in search results.
Matt Cutts
The main thing to remember...
Matt Cutts
...is that Google social search makes your results more relevant.
