Google Analytics now provides a new Asynchronous Tracking Code snippet as an alternate way to track your website!
Think of the asynchronous tracking code snippet as a script that uses a "separate lane" to handle part of the processing of your webpage. As the number of cars (or in this case, scripts on your webpage) increases, the asynchronous tracker uses this lane to reduce webpage load time. Websites that use many scripts or rely on rich media content will especially benefit from this new method, but even lightweight sites will see improvements.
The new tracking snippet offers the following benefits:
Faster tracking code load times for your web pages due to improved browser execution
Enhanced data collection and accuracy
Elimination of tracking errors from dependencies when the JavaScript hasn't fully loaded
The asynchronous tracking code is now in Beta and available to all Google Analytics users. Using the new tracking code is optional: your existing Google Analytics code will continue to work as-is. But if you want to improve your webpage load times and fine-tune the accuracy of your Analytics data, then we think you'll love this new option.
