Can Google see all my sites that use the same Piwik installation?

I have been wondering if it would be possible for google to see all my sites that are using the same token to track my traffic? I have mostly personal sites on my Piwik installation but have some other sites that I do not want to have any connection between them to be found. Any help on this topic would be great.

The Piwik URL is found in the javascript code. You can make it a different domain on each website by doing a special procedure, hide your piwik footprints

Awesome thanks for the response.
