Google Analytics Asynchronous Code Improves Page Load Time
April 28th, 2010
Google introduced Asynchronous Tracking as an “alternate way to track” websites. To recap the benefits of using the new asynchronous ga.js snippet over the older ga.js are:
- Faster tracking code load times via improved code execution
- Improvements in data collection accuracy
- Elimination of tracking errors caused by the ga.js snippet not being fully loaded
A recent Google Analytics script test preformed by Position 2 reveal quantifiable speed increases when using the asynchronous.
Analytics Tracking Code Test Key Findings
Position 2 observed the following results from their test:
- A 17% speed increase in page load using the asynchronous ga.js over the traditional ga.js code
- Page placement has little effect on the asynchronous ga.js load time conpared to the traditional ga.js
- Top of the page placement no longer slows the page load. This is important when tracking clicks is and possible while page is loading content.
