Make Google Analytics load faster with asynchronous tracking

by Patrick Altoft on December 2, 2009 / 8 responses

With site speed apparently set to be a factor in the 2010 Google algorithm webmasters are looking for easy ways to speed up their sites and Google wants to help.

The latest Google Analytics code loads asynchronously allowing your page to load faster – download it here.

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.
