If you are the creator of a website or web application yourself, you might want to install the rack-preview gem for Ruby, or something similar. We discovered Safari Top Sites was polluting Splitwise’s Google Analytics and Mixpanel data.
A couple of weeks ago, while digging into our site analytics, we noticed something strange with Safari. We’d just launched Fat Rabbit and were really interested in making sure we measured all the useful statistics around user growth and engagement. As we pulled out interesting details about website visits (using a combination of Google Analytics and Mixpanel), we started seeing an odd pattern – the average visit length on Safari was half that of our other browsers and the bounce rate was much higher.
