Another thing to watch for are IP’s that are continuously creating bounces.  Very often, the site owner can be the source of many of the bounces simply because they are checking their ranking or are showing a client their home page, or simply because they have it set for their home page.  In order to stop this, you need to go to the Google Analytics and add the ip of the office to the filter manager.  This way, your internal traffic won’t skew the numbers.

This also applies for Google Maps.  If you see your website on a serp, you always want to click on it and go through a few pages if you are on an ip which is not in the filter manager.  Good luck!
