Here is a quick post found on the keynote site on how to remove keynote sessions from Google Analytics. We recently added GA to the Ford site I run and wanted to exclude our monitoring visits to get real results.

Just implemented as suggested in this post: http://blogs.keynote.com/the_watch/2011/09/filtering-out-web-performance-monitoring-traffic-from-google-analytics.html

As the post notes it does not apply to historic traffic so I guess I have to wait until tomorrow to see if it really works.

Thanks Keynote!
