Using advanced segments in Google Analytics is something that you must consider if you are interested in how your web sites performs and how to improve the quality of traffic. The way I use advanced segments is to improve traffic that has high bounce rates or from people that spend less than 1 minute on my web site or people that are browsing only 1 page. The great advantage is the fact that you can see from what region that traffic comes, what keywords lead people to your web site or what landing pages were returned by search engines. This way you will be able to address each segment of visits and this way you’ll be able to improve the quality of traffic on your web site.
